Four pre-registered online forced-choice precognition experiments investigated whether yoga and meditation practice enhances precognitive ability among Indian yoga university students (total N=273). Study 1 (N=104) tested a 40-day yoga course, Study 2 (N=103) tested cyclic meditation, Study 3 (N=164) compared experienced vs. beginner practitioners, and Study 4 (N=245) examined demographic and personality correlates. None of the pre-registered hypotheses reached statistical significance (all d < 0.08), but post hoc analyses revealed consistent psi-missing across all three experimental studies (e.g., Study 1 post-intervention: 14 missers vs. 3 hitters, p<0.001).

Perspective article arguing that near-death experiences warrant systematic identification and management in emergency and intensive care settings. Reviews NDE incidence data (approximately 20% of cardiac arrest survivors, 15% of ICU survivors, and possibly 58-64% of pediatric survivors) and discusses enduring psychological impacts including reduced death anxiety, increased meaning, and post-traumatic growth, while noting that at least 14% of NDEs are distressing. Proposes incorporating NDE screening via the NDE-C scale into clinical care plans, differentiating NDEs from delirium, and attending to set-and-setting factors that may modulate NDE valence. Draws parallels with psychedelic experiences and discusses pharmacological concerns around sedation suppressing potentially beneficial NDE recall.

Forty-seven participants selected through a worldwide three-phase recruitment for attentional expertise each received a custom optical diffraction grating apparatus and completed 10 formal half-hour sessions with alternating 30-second observe/unobserve periods. Illumination at one first-order maximum was provided as real-time feedback while a second was recorded simultaneously but never observed. Three preregistered hypotheses were not supported overall, though differential skew was significant after FDR correction. An exploratory trend analysis found progressive interference decline during observation versus the simultaneous unobserved control (p = 5.9 x 10^-14), with no such pattern during non-observation periods (p = 0.77) or in 212 control sessions run without observers.

This study tested the hypothesis that collective human focus and emotional resonance during New Year's Eve midnight celebrations produces measurable departures from randomness in a global network of random number generators (RNGs). Analysis of Global Consciousness Project (GCP) data spanning 1998-2025 (27 years, 33 billion samples, 6.6 trillion bits) employed seven analytical methods: mean-shift, correlation dimension, permutation entropy, Higuchi fractal dimension, BDS test, autocorrelation, and Principal Components Analysis (PCA). Results revealed statistically significant deviations at or within minutes of midnight on New Year's Eve compared to all other midnight transitions (PCA: z=-4.9, p=4.8×10^-7). Mean-shift analysis showed 6-sigma deviation from 2.3 minutes before to 2.0 minutes after midnight (joint probability=0.00029). High population time zones (6.8 billion people) showed significant deviations; low population zones (629 million) did not, suggesting effect scales with number of minds engaged. Effect survived temporal scrambling of RNG timestamps by ±60 seconds. Alternative mundane explanations (environmental artifacts, data glitches) deemed unlikely given RNG design and specificity to New Year's Eve.

Telecommunication Telepathy: A Meta-Analysis

Sheldrake, Rupert et al. • 2025

Basic MA

Can people identify who is contacting them before answering when several possible callers exist? This meta-analysis pooled 26 telecommunication telepathy experiments from 15 papers (2003-2024), covering telephone, email, SMS, and automated protocols, and applied random-effects modeling (REML with Hartung adjustments). Telepathy-condition performance was 8.7% above chance (95% CI 5.3-11.9; standardized ES = 0.17, p = 1x10^-7), whereas three precognition-condition datasets were near chance. Moderator analyses showed stronger effects for preselected participants and emotionally bonded pairs, with publication-bias sensitivity checks indicating the overall signal remained significant.

This editorial introduces a Research Topic on self-ascribed parapsychological abilities, marking a shift from proving/disproving psi to understanding psychological underpinnings. Synthesizes findings from multiple contributions: Dagnall et al. found paranormal beliefs serve adaptive coping functions while conspiracy theories link to avoidant coping; Simmonds-Moore et al. identified overlap between psychometry and synesthesia/ASMR; Michael et al. showed DMT experiences and NDEs share phenomenological similarities (entity encounters, ego dissolution); Toriz et al. observed beta/gamma oscillations in shamanic trance; Chaudhary et al. reviewed fMRI studies showing meditation activates alertness networks. Concludes self-ascribed abilities link to cognitive-perceptual traits, heightened sensitivity, and altered states.

A pro-psi perspective piece responding to the global debate sparked by The Telepathy Tapes podcast (2024), which featured nonspeaking autistic individuals appearing to convey information beyond ordinary sensory channels. Weiler and Woollacott argue that critics conflate S2C and independent typing with the historically discredited FC method — noting that 9 of 22 podcast participants communicated entirely without physical support, ruling out facilitator influence for those cases. Eye-tracking evidence (Jaswal et al. 2020) supports intentionality in letterboard use. Drawing on a century of parapsychological research on mind-to-mind communication, the authors argue the telepathic claims deserve rigorous controlled study rather than reflexive dismissal rooted in FC stigma.

Using network analysis (EBICglasso) on a cross-sectional survey of 1,667 UK adults, interrelationships between paranormal belief (PB), conspiracy theory endorsement (CT), schizotypy, and positive wellbeing factors were examined. PB and Self-Esteem emerged as the two most central nodes. PB linked most strongly with CT (r = 0.60), cognitive-perceptual schizotypy (r = 0.56), search for meaning (r = 0.42), and avoidant coping (r = 0.40). Though correlated, PB and CT related differently to wellbeing: PB correlated positively with presence of meaning while CT did not, and CT correlated negatively with life satisfaction while PB did not. PB appeared to mediate relationships between schizotypy, meaning-seeking, and avoidant coping, while self-esteem bridged coping, meaning in life, and life satisfaction.

Planning Falsifiable Confirmatory Research

Kennedy, James E • 2024

Non-Empirical

Falsifiable research requires that study designs can provide evidence a hypothesis is false as well as true. This article integrates power analysis, equivalence testing, Bayesian operating characteristics, and preregistration into a framework for falsifiable confirmatory research. Power >= .95 for a prespecified minimum effect size is optimal; .90 is good. If any nonzero effect is considered meaningful, the hypothesis is unfalsifiable. For d = 0.20, sample sizes of 858-1,084 are needed at adequate power. The alternative hypothesis can be rejected via noncentral t distributions when power is high. Preregistrations should specify criteria for evidence the hypothesis is true, false, or inconclusive. Retrospective meta-analyses are exploratory; prospective meta-analysis is preferred.

Policy and practice review analyzing three strategies for addressing researcher fraud: (1) retrospective investigations after allegations — common but vulnerable to post-hoc bias, low evidentiary standards, and inability to identify perpetrators; (2) real-time sting operations — conclusive when feasible, but rarely practicable; (3) preventive data management practices from FDA-regulated clinical trials — largely absent from academic research. Eight preventive practices are described: archiving raw data, audit trails, restricted data access, software validation, quality control, blinding with preregistered analysis programs, research audits, and public raw data. Proposes an 'error-controlled data management' badge for studies meeting these standards. AI is identified as a looming escalation of fraud sophistication.

Cross-sectional survey comparing cognitive styles among four groups: academic psi researchers (N=44), lay psi believers (N=32), academic skeptics (N=35), and lay skeptics (N=33). Measured actively open-minded thinking (AOT) and need for closure (NFC) using validated scales, plus psi beliefs/experiences via the NEBS. Found significant group differences in AOT (F(3,138)=4.8, p=0.003, η²=0.09): psi researchers scored identically to academic skeptics (4.5±0.3 vs 4.5±0.3, p=0.91) and lay skeptics (p=0.80), while lay psi believers scored significantly lower (4.2±0.4, ps: 0.005-0.04). No differences in NFC (p=0.67). Results held after controlling for age and education. The AOT-belief inverse correlation was driven entirely by skeptics (r=-0.29, p=.01) and was null in psi groups (r=-0.03, p=.78).

A convergent mixed methods online survey (N=164) investigated how autonomous sensory meridian response (ASMR) and synesthesia relate to psychometry — the experience of receiving information about a person by touching objects. Psychometry experiencers scored significantly higher on ASMR (t(159)=-3.06, p=0.003, d=0.5) and on anomalous experiences with paranormal attribution (d=1.2). Synesthetes scored higher on ASMR and anomalous experiences but were not significantly more likely to report psychometry (p=0.078). Thematic analysis of 47 descriptions identified five themes: contextual framing, flash of imagery, intense emotions, noetic knowing, and perspective-taking/empathy. The author concludes ASMR-related sensitivity may partly underpin psychometry phenomenology.

Both frequentist (REML with Knapp-Hartung adjustment) and Bayesian random-effects models yielded convergent estimates: ES ≈ 0.08 (95% CI [0.04, 0.12]; BF₁₀ = 89.5). Four publication bias tests (3PSM, p-uniform*, RoBMA, Mathur-VanderWeele sensitivity) indicated results are robust. Cumulative meta-analysis showed effect stabilization since 1997; meta-regression found no decline (slope = 0.0012, p = 0.53). Moderator analyses revealed selected participants produced ES = 0.13 vs. 0.04 for non-selected; telepathy-type tasks (Type 3) showed ES = 0.08 vs. 0.04 for clairvoyance (Type 2).

Four Buddhist monks directed meditative intention into bottles of ultrapure water with the specific aim of causing beneficial changes in glioblastoma cancer cells. In a double-blind design, U87MG human glioblastoma cells were cultured in growth media prepared with treated vs. untreated water, and cell migration was measured via wound healing assay at 0, 3, 6, and 9 hours across three experimental replications. Cells in treated water migrated significantly less: repeated measures ANOVA yielded a time x water condition interaction of F(3,9) = 8.560, p = 0.005 (Huynh-Feldt corrected p < 0.008). At 9 hours, migration was reduced by approximately 25%. The study extends the Shiah/Radin treated-water paradigm to a clinically relevant cancer cell line.

A pre-registered study tested whether participants could guess who was calling them using a fully automated Twilio/PHP system. 177 participants in triads completed two randomized trial types: telepathic/pre-selected (caller chosen before guess) and precognitive/post-selected (caller chosen after guess). Pre-selected trials yielded 48.1% accuracy versus 33.3% chance (p < .001), while post-selected trials showed no above-chance performance (32.5%, p = .61). Genetic relatedness at 25% predicted 2.88× higher odds of accuracy (P = .04), and communication frequency was significant (P = .03). Results favor a telepathic over precognitive mechanism, though potential cheating in pre-selected trials where participants could be co-located remains uncontrolled.

A Comparison of Four New Automated Telephone Telepathy Tests

Sheldrake, Rupert & Stedall, Tom • 2024

Non-Empirical

Four automated telephone telepathy experiments compared conference-call and separated-trial formats using the Twilio platform. In Experiments 1–3, three participants remained connected in a conference call; a randomly chosen caller thought about the receiver, who guessed the caller's identity (2-choice, 50% chance). None showed significant effects: Exp 1: 51% (1,047 trials), Exp 2: 51% (231 trials), Exp 3: 52% (447 trials). Experiment 4 separated callers and receivers between trials, allowing normal activity between randomly timed calls. In 266 trials, the hit rate was 57% (p = .01, one-tailed binomial). The positive effect was distributed across participants (36 positive vs 17 negative tests, p = .006), ruling out optional stopping and minority-cheater explanations.

Emotional intelligence was measured via the MSCEIT. Group 2 (believers/images) scored significantly above chance (M=10.09/32, d=0.853, BF₁₀=60.5), exceeding the average SAIC effect size of d=0.447. The experiential area of EI predicted 19.5% of RV hit variance in Group 2. Participants with low experiential EI (<89) scored below chance. A triple-blind protocol with SEM invariance analysis addressed prior criticisms by Hyman (1996) and Utts (1996). Authors conclude RV is statistically but not empirically verified.

Proposes a non-substance dualism in which reality consists of ontologically real Possibles (Res potentia, following Heisenberg's 1958 concept) that do not obey Aristotle's law of the excluded middle, and ontologically real Actuals (Res extensa) that do. Mind acausally converts Possibles into Actuals through measurement, breaking the causal closure of classical physics and allowing consciousness an active role. This single hypothesis is claimed to explain five quantum mechanics mysteries. Reviews supporting evidence from ganzfeld experiments (30.6% hit rate, 8.1σ), forced-choice precognition (11σ), presentiment (5.3–6.9σ), dice PK (19σ), RNG experiments (6.8σ), and double-slit consciousness studies (cumulative p < 4 × 10⁻¹¹). Argues that quantum mind provides a basis for responsible free will.

Systematic analysis of 54 studies (27 case reports, 20 case series, 7 qualitative studies) spanning 1980-2022, involving 465 NDErs across multiple cultures and religions. Screened 2,407 initial records from PubMed, Scopus, EMBASE, CINAHL, and Google Scholar using PRISMA-P guidelines and JBI quality appraisal. NDEs were categorized into 4 main categories with 19 subcategories: emotional, cognitive, spiritual/religious, and supernatural experiences. Supernatural experiences—especially out-of-body experiences (35/54 studies) and heightened senses (39/54 studies)—were the most frequently reported. A universal phenomenological core (OBEs, tunnel passage, heightened senses, life review) was found across all cultures, with cultural variation confined to interpretation rather than experiential structure.

Meta-analysis of 16 telepathy experiments from 9 articles published over the prior 20 years, encompassing 21,441 total trials across telephone, email, SMS, card-guessing, and virtual-environment paradigms. Effect sizes were calculated as the deviation of observed from expected hit rates normalized by binomial standard deviation, then weighted by trial proportion. The overall weighted effect size was 0.091 (average unweighted 0.15), indicating a small positive effect. Twelve of 16 experiments (75%) showed statistically significant above-chance hit rates. Decline effects were observed when high-scoring participants were retested. The author notes limitations including possible cheating, confounds with precognition or clairvoyance, and variable replication success across labs.

Neuro-functional models of near-death experiences (NDEs) are evaluated to determine whether NDEs can be explained as brain-based phenomena occurring during altered states of consciousness (ASCs). Evidence is drawn from drug effects (ketamine, DMT), epileptic seizures, electrical brain stimulation, anesthetic awareness, and ischemic stress, including ~1,000 fighter pilot G-LOC episodes recorded across 16 years. A large overlap was found between NDE themes from original reports and those induced experimentally. Out-of-body experiences can be localized to the temporo-parietal junction (TPJ). The models collectively suggest NDEs emerge as hallucination-like phenomena from brains in ASCs.

Reanalysis of the complete Global Consciousness Project database (August 1998 – December 2021, ~6 trillion random bits from a worldwide RNG network) using multiscale entropy (MSE) and a novel deconvolution technique. MSE found original data significantly more negentropic than scrambled controls (z = –3.45, p = 0.0003, es = –0.16). Deconvolution detected significant temporal structure at 8–15 minute scales (z = 5.08 vs controls, p = 1.9 × 10⁻⁷, es = 0.43). Crucially, the effect was present on days with no pre-selected global events (z = –6.22, p = 7 × 10⁻¹¹), suggesting a continuous rather than episodic mind-matter relationship.

Tests whether daily Twitter sentiment data in 10 languages shows anticipatory declines before unpredictable negative world events (terrorism, mass shootings, unexpected celebrity deaths). Thirteen years of hedonometer.org sentiment data (2009-2023) were filtered through a four-step process to identify 83 unpredictable negative events. Ensemble averages of sentiment from 14 to 2 days before each event were analyzed via linear regression slopes corrected with circular-shift permutation testing.

Across 10 laboratories in 9 countries, 2,115 participants completed 37,836 forced-choice erotic trials. Hit rate was 49.89% (chance = 50%), yielding BF₀₁ ≈ 72 — strong Bayesian evidence for the null model. The 90% HDI for population success rate was [49.57%, 50.40%], with >99% probability below 50.6%. Credibility-enhancing tools included direct data deposition, born-open data, real-time reports, external audits, and tamper-evident software.

Cognitive activity during cardiac arrest (CA) was examined in a prospective 25-site study across US and UK hospitals (May 2017-March 2020). Independent audiovisual awareness testing and continuous real-time EEG and cerebral oxygenation (rSO2) monitoring were incorporated into CPR during in-hospital CA. Of 567 IHCA, 53 survived (9.3%); 28 completed interviews and 11 (39.3%) reported memories suggestive of consciousness. Four experience categories emerged: CPR-induced consciousness (7.1%), post-resuscitation awareness (7.1%), dream-like states (10.7%), and transcendent recalled experiences of death (21.4%). Despite marked cerebral ischemia (mean rSO2=43%), normal EEG activity (delta, theta, alpha) consistent with consciousness emerged 35-60 minutes into CPR. No survivor identified hidden visual targets; one showed inconclusive implicit auditory recall.

Systematic review of 71 studies (N=20,993) examining associations between paranormal beliefs and cognitive functioning published 1980-2021. Study quality was assessed using the AXIS tool. Results show 75% of studies rated good-to-strong quality, with quality improving over time. Most consistent findings: paranormal belief associated with increased intuitive thinking style (8/8 studies), increased confirmatory bias, poorer conditional reasoning, and reduced perception of randomness. Two-thirds of studies document poorer cognitive performance in believers. Major methodological weaknesses identified: only 7% included a-priori power analyses, 3% preregistered, 63% used undergraduate samples, 17% corrected for multiple comparisons. Authors propose a fluid-executive model suggesting disparate cognitive deficits may reflect common underlying executive dysfunction.

This correlational study examined associations between 16 specific near-death experience (NDE) features and five death attitude variables in the largest-to-date sample of NDE reporters (N = 384 NDErs from 422 total participants). Using Spearman correlations with Bonferroni correction (p < 0.003), encountering mystical beings and undergoing a life review emerged as the strongest predictors of reduced Fear of Death (rho ≈ -0.22). Cosmic unity and mystical beings predicted lower Death Anxiety. Approach acceptance was predicted by joy, bright light, mystical beings, and encounters with deceased persons. Contrary to theoretical predictions, out-of-body disembodiment was not associated with reduced fear of death. NDErs showed markedly lower fear of death and higher approach acceptance than non-NDErs and normative samples. Findings have implications for end-of-life interventions and challenge Terror Management Theory assumptions.

Experimental evidence of non-classical brain functions

Kerskens, Christian Matthias & López Pérez, David • 2022

Non-Empirical

Using proposals from quantum gravity that entanglement between two known quantum systems can witness non-classicality in a mediating system, this study applied zero quantum coherence (ZQC) NMR protocols to 40 human volunteers at rest in a 3T MRI scanner. Evoked signal bursts resembling heartbeat-evoked potentials appeared in most brain regions with up to 15% signal increases. These signals showed definitive ZQC characteristics (magic angle dependency R²=0.9958, optimal flip angle at 45° R²=0.9964, MTC immunity), had no classical NMR contrast correlates, surpassed classical bounds, and depended on conscious awareness—declining during sleep. The authors conclude these constitute experimental evidence of non-classical (quantum) brain functions.

This paper presents a clinical approach to counseling individuals who report distressing subjective paranormal experiences, termed anomalous or exceptional experiences. Approximately one-third to one-half of the population reports such experiences, with nearly half experiencing difficulty integrating them. The author describes the main components of a Psychodynamic Psychotherapy focused on Anomalous Experiences (PPAE) based on clinical work at CIRCEE, which has conducted over 750 counseling sessions since 2009. The approach involves three steps: phenomenological exploration using micro-analysis techniques, subjective inscription (emotional containment, de-pathologization, and detachment), and subjective integration of meaning. The clinical attitude of undecidability and non-judgmental listening facilitates transformation of ontological shock into psychological integration.

This review examines phenomena that contradict the notion that consciousness is exclusively dependent on brain activity. Six categories are reviewed: (1) remote viewing meta-analyses show significant evidence for perceiving distant locations; (2) ganzfeld telepathy studies (120+ experiments, ~4,000 trials) show 31% hit rate vs 25% chance; (3) presentiment meta-analyses demonstrate physiological responses 1-10s before future stimuli (Mossbridge et al. 2012: d=0.21, p<2.71×10⁻¹²); (4) xenoglossy and acquired savant syndrome cases; (5) non-local experiences reported by 10-97% across populations; (6) terminal lucidity in dementia patients with 80%+ complete remission before death. Non-local consciousness theories (operational probabilistic theory, interface theory, analytic idealism, Orch-OR) are compared to physicalist models (GWT, HOT, IIT, predictive processing). The authors propose consciousness may be fundamental rather than emergent, with non-local properties transcending spacetime constraints.

Self-Ascribed Paranormal Ability: Reflexive Thematic Analysis

Drinkwater, Kenneth Graham et al. • 2022

Non-Empirical

Investigated how 12 individuals with self-ascribed paranormal abilities (mediums, psychics, sensitives, clairvoyants) perceive and make sense of their professed powers through semi-structured interviews analyzed with reflexive thematic analysis (RTA). Four themes emerged: Formative Influences (childhood experiences and gifted family members), (Inter)Subjective Paranormal Experience (transcendental/mystic encounters and ESP), Embodied Processes (sense of control over abilities), and Perception of Reality (self-awareness and surreal perceptions). These themes mapped onto lifeworld fractions of temporality, inter-subjectivity, embodiment, and spatiality. Self-ascription operates as an attributional process where individuals construct coherent narratives to contextualize and validate their claimed powers, with belief reciprocally reinforcing paranormal interpretation of anomalous experiences.

Adapts a medical evidence-grading framework (A–F) to evaluate nine categories of survival-of-consciousness evidence. Mental and physical mediumship received the highest grades (B+); reincarnation and NDE OBE aspects received B−; EVP/ITC and deathbed visions received C+; apparitions, induced experiences, and ADCs received C. No category achieved grade A, primarily because the psi-vs-survival interpretive confound cannot be resolved with current methods. Proposes ten new experiments and surveys 422 academics: controlled veridical OBEs during NDEs ranked most persuasive (mean 14.4/50), followed by mediumship (9.6) and reincarnation (9.0).

Psychometric validation of the CAPE-P15—a 15-item self-report scale measuring psychosis-spectrum experiences (paranoid ideation, bizarre experiences, perceptual anomalies)—in 1,594 Chilean adolescents (ages 12–19). Using Item Response Theory, item discrimination parameters ranged from moderate (α=1.05) to very high (α=2.44); scale reliability was high (α=0.94, ω=0.81). Both unidimensional and hierarchical models fit acceptably; the test information function was most accurate between −1 and +2.5 SD. Items assessing auditory/visual hallucinations and being controlled by external forces showed highest discriminative power.

An experiment conducted from 2012 to 2013 at the Institute of Noetic Sciences explored possible psychophysical effects on a double-slit optical system. 25 participants focused attention toward or away from the slits in 250 planned sessions inside an electromagnetically shielded chamber. Matched sham sessions without observers served as controls. The planned analysis found no evidence for a psychophysical effect. Two exploratory analyses were then developed: a simplified spectral metric yielded a 3.4 sigma effect (p = 0.0003), and fringe visibility analysis showed 7 of 22 fringes above 2.3 sigma after FDR correction, with one at 4.3 sigma (p = 0.00001). Sham data showed uniformly null outcomes. Environmental artifact analyses (temperature, vibration) found no mundane explanations. The 8-year delay between data collection and publication was due to the study funder's request to withhold results pending his own analysis.

Is the Sun Conscious?

Sheldrake, Rupert • 2021

Non-Empirical

Applying panpsychist philosophy and electromagnetic field theories of consciousness to the sun, this article argues that self-organizing systems at all levels of complexity — including stars — might possess awareness. The sun's electromagnetic complexity, with millions of granulations, sunspots, solar flares, and coronal mass ejections, creates an integrated field spanning the heliosphere. Under IIT, the sun plausibly has high Φ, though computation is intractable. EM field theories (McFadden's CEMI, Pockett, Murphy) suggest the sun's integrative fields could be conscious. Solar cognition would be slow: ~4.6 s across the sun's diameter, ~16.7 hours to sense the heliopause.

Basic MA

Umbrella review of 11 meta-analyses conducted between 1989 and 2021, encompassing 928 studies of anomalous cognition across six states of consciousness and three response types. All 16 reported effect sizes were statistically significant except for slow-thinking forced-choice precognition (ES = 0.03). Effect sizes ranged from 0.005 (forced-choice clairvoyance) to 0.39 (remote viewing free-response). State of consciousness and response type were strong moderators (Spearman rs = .81, p = 1.9 × 10⁻⁴): altered states with free-response protocols and physiological anticipation measures yielded the largest effects, while forced-choice paradigms in normal consciousness yielded the weakest. Between 54% and 81% of individual studies in most meta-analyses were non-significant, which the authors argue militates against questionable research practices.

Nine nonspeaking autistic young adults who communicate by pointing to letters on a hand-held letterboard wore head-mounted eye trackers while answering 24 comprehension, spelling, and open-ended questions about a lesson read aloud by a familiar assistant. Frame-by-frame video coding (30 fps, inter-rater κ = 0.88–0.94) showed letter accuracy of 94%, word accuracy of 83%, and a median inter-point interval of 952 ms (~1 letter/second from 26 alternatives). Anticipatory gaze fixations preceded pointing on 71% of letter selections by a median of 476 ms. IPI was significantly longer at word boundaries (b = 0.75, p < .0001) and shorter for high bigram-frequency pairs (β = −0.18, p < .0001), paralleling timing signatures of fluent spelling in non-autistic typists. These patterns render a cueing account unlikely and provide objective evidence that the participants, not the assistant, authored their communications.

Preregistered, multi-lab replication of Maier et al. (2014, Exp. 4) testing retroactive avoidance — unconscious anticipatory avoidance of randomly selected future aversive stimuli. Across five labs in Germany, Italy, Russia, France, and Sweden (N=2,004), participants completed 60 binary key-press trials with quantum-based random stimulus selection and masked picture presentation. Sequential Bayesian analysis yielded BF01=4.38, moderate evidence against retroactive avoidance. Wider priors produced BF01>30. Meta-analytic effect size across labs was ES=0.008 (p=.76) with negligible heterogeneity. Exploratory temporal analyses combining original and replication data (N=2,328) found non-random oscillations in the sequential BF curve, consistent with Generalized Quantum Theory predictions.

Argues that psi research faces a fundamental epistemological paradox: if psi exists, it violates the observer-independence assumption underlying the scientific method, meaning that proving psi retroactively invalidates the experimental framework used to prove it. Using the Ganzfeld protocol and Bem's (2011) precognition experiments as case studies, traces an infinite logical loop where successful psi demonstrations undermine their own evidential basis. Connects this paradox to the broader replication crisis in psychology, the decline effect, and proposes Lucadou's Model of Pragmatic Information as a framework for moving beyond classical experimental approaches.

An update to Storm, Tressoldi, and Di Risio (2010), this meta-analysis assessed free-response ESP studies from 2009-2018 in three categories: ganzfeld (k=9, ES=0.119), nonganzfeld noise-reduction (k=19, ES=0.045), and standard free-response (k=15, ES=0.050), all with significant Stouffer Z scores. Combined with 1992-2008 databases (total k=108), ganzfeld yielded ES=0.133 (95% CI [0.071, 0.194], p=1.37x10^-9), noise-reduction ES=0.072, and standard free-response ES=0.027. No decline effect appeared across 44 years. Ganzfeld significantly outperformed standard free-response, and selected participants outperformed unselected in ganzfeld.

An independent replication of a micro-psychokinesis experiment tested whether anomalous correlations arise between human operator behavior and a Zener-diode random number generator. 244 participants (503 valid experiments) interacted with an RNG-driven fractal display using shift keys while intending to direct its movement. A 45×45 Spearman correlation matrix crossing five physical and five psychological variables per subrun was compared between experimental and matched control runs via a 10,000-iteration permutation test. The experimental matrix contained 307 significant correlations (p < .1 two-sided) versus 200 in controls (chance expectation ~203), yielding p = .0177. Significance held across stricter thresholds and for the 27×45 matrix but not for the original 18×27 matrix. The authors interpret results as supporting non-causal entanglement-like correlations rather than direct psychokinetic influence.

This theoretical paper argues for a complementarist dual-aspect monism ontology where consciousness and matter are coprimary aspects of an underlying reality, not reducible to either. Walach traces how 'experience' historically narrowed from Roger Bacon's bimodal conception (inner spiritual and outer sense experience) to modern empiricism's exclusive outer focus. The materialist ontology cannot explain consciousness itself or anomalous cognition (telepathy, precognition, psychokinesis), which have robust meta-analytic support but defy locality assumptions. A complementarist model (inspired by Bohr, Pauli-Jung unus mundus) permits epistemological access through both outer sense experience and inner contemplative experience. The paper proposes 'contemplative science' where scientists trained in contemplative practices systematically explore inner experience as complementary to third-person neuroscience, potentially accessing deep reality structures including mathematical intuition and ethical values.

Response to Radin et al.'s (2020) commentary defending the Radin double-slit experiment on observer consciousness. A funder-commissioned replication using an advanced meta-experimental protocol (AMP) with data encryption found a significant false-positive effect (p = 0.021, σ = −2.02, N = 1,250 trials) but no significant effects where Radin had predicted true positives. Documents two instances of HARKing by Radin et al.: (1) a chi-square test falsely claimed as pre-specified was actually post-hoc, and (2) a call for multiple-testing correction that abandoned the planned predictive single-testing strategy after unblinding. Three independent sources (Guerrer 2019, Tremblay 2019, Walleczek & von Stillfried 2019) converge on the conclusion that the Radin DS-experiment is prone to false discoveries, particularly with post-hoc analyses.

Case studies show all three share Stace's core mystical attributes (unity, sacredness, noetic quality). Neuroimaging reveals significant Default Mode Network deactivation during meditation and psilocybin ingestion, with flatlined EEG during cardiac arrest NDEs. Proposes a filter/reducing valve theory: when DMN activity is reduced or eliminated, expanded consciousness becomes accessible.

A formal reply to Walleczek and von Stillfried (2019), who claimed a false-positive in one of eight comparisons from an unpublished 2012–2013 double-slit consciousness experiment funded by Walleczek's foundation. Radin et al. argue the design required multiple-comparison correction: with eight non-overlapping tests at p < 0.05, the probability of at least one false positive was 34%. After applying the False Discovery Rate algorithm, none of the eight mean comparisons remained significant, but a pre-planned variance comparison not reported by WS survived FDR correction, suggesting a genuine but unstable observer effect. Across 28 double-slit experiments by four independent groups, 11 were significant (p < 0.05), with cumulative binomial probability p < 10⁻⁷.

Interest in near-death experiences (NDEs) has grown rapidly but the standard measurement tool — Greyson's (1983) NDE scale — shows several psychometric weaknesses. Across three studies with 564 French-speaking participants, a new 20-item Near-Death Experience Content (NDE-C) scale was developed and validated. Study 1 (N=403) identified structural weaknesses in the Greyson scale's factor structure. Study 2 (N=161) established the NDE-C scale's 5-factor structure (Beyond the Usual, Harmony, Insight, Border, Gateway) with Cronbach's α=0.85 and concurrent validity correlations above 0.76. Study 3 showed the scale discriminates NDEs from drug-induced, meditation, and trance experiences, with Border and Gateway factors being most distinctive. A cut-off score of ≥27/80 is proposed for research use.

Reviews four behaviors: (1) eye contact avoidance reflects sensory discomfort and adaptive processing, not disinterest; (2) reduced pointing stems from motor planning difficulties, not absent communicative intent; (3) motor stereotypies serve regulatory functions uncorrelated with social impairment; (4) echolalia functions communicatively and for self-regulation. Draws on cross-cultural research, motor/sensory literature, and autistic testimony to argue that misinterpreting these behaviors as diminished social motivation creates self-fulfilling prophecies.

A broad-based critique of parapsychology published as a direct rebuttal to Cardeña (2018) in American Psychologist. Argues psi phenomena are impossible because they violate four fundamental principles: causality (no mechanism exists), time-asymmetry (precognition requires time reversal unsupported by physics), thermodynamics (psychokinesis creates energy in closed systems), and the inverse square law. Dismisses quantum mechanics and relativity as scaffolding for psi, critiques parapsychological meta-analyses as built on marginal individual studies, and highlights Bem's 2017 interview admission that his precognition studies were "rhetorical devices." Concludes parapsychology persists due to isolation from mainstream science, unfalsifiability, and appeal of secular dualism.

An applied remote viewing experiment at the buried ancient city of Marea, Egypt, in which two experienced viewers — George McMullen and Hella Hammid — independently located and described a 6th-century Byzantine structure under triple-blind conditions before excavation in April 1979. Viewers predicted wall depths (confirmed at 3 ft 4 in vs. predicted 3–4 ft), three rooms, doorway and corner positions, the color green, and marble mosaic tiles; all major predictions were confirmed by excavation. A direct comparison with a 1976 electronic remote sensing survey (proton precession magnetometer, satellite imagery) by Prof. Mahmoud Sadek showed the electronic survey found no sub-surface structures at this location, while remote viewing produced the only positive predictive data.

Twelve blind wine-tasting experiments tested whether group meditation intention could alter aesthetic preference for wine. Each session used a single 750ml bottle decanted into two 375ml carafes; one received 20-30 min intention from 6-10 meditators (93 total intenders), the other served as control. Seven blinded tasters per session (84 total) voted preference. Eleven of 12 sessions showed majority preference for treated wine (binomial p=0.00049); 95% CI [0.76, 1.0]. Effect consistent across different intender groups, party hosts, and session compositions.

Morphic fields — organizing fields within and around self-organizing systems — may explain telepathy and the sense of being stared at (scopesthesia) as natural biological phenomena. Seven postulates of formative causation are presented, proposing that minds extend beyond brains via perceptual fields linking observers to objects, with telepathy occurring through interaction between bonded members of social groups within the group’s morphic field. Supporting evidence cited from prior work includes stare detection trials significantly above chance, CCTV/galvanic skin response studies showing unconscious physiological detection, and animal telepathy research (dogs anticipating owners’ returns, parrot language-based telepathy). The framework differs from quantum-based psi models by starting from holistic biology, predicting effects dependent on attention, intention, and emotional bonding rather than attenuating with distance.

A conceptual replication of the Radin double-slit (DS) experiment was commissioned using 10,000 test trials performed blindly by the same investigator who reported the original results. The Advanced Meta-Experimental Protocol (AMP) implemented systematic negative, positive, and time-reversed controls alongside a sham-experiment conducted without test subjects. The replication failed to confirm the original anomalous consciousness effect (0% true-positive match rate). Critically, the sham-experiment revealed a statistically significant false-positive effect (p = 0.021, σ = −2.02, N = 1,250) in exactly the test category predicted for a true-positive result. The false-positive effect size (~0.01%) was within an order of magnitude of the claimed consciousness effect (0.001%), and its statistical significance matched that of the original study. These findings demonstrate that the DS-apparatus produces significant effects without observers present, calling into question all prior claims of anomalous observer consciousness effects.

Investigated the prevalence, classification, and phenomenology of distressing near-death experiences in 123 NDErs recruited through the Coma Science Group (Liège). Using the Greyson NDE Scale and Memory Characteristics Questionnaire, 17 experiences (14%) were classified as distressing — higher than the 1–10% reported previously. Multiple coders categorized these into 8 inverse, 8 hellish, and 1 void accounts, confirming Greyson and Bush's (1992) taxonomy with high inter-rater reliability (kappa = 0.855–1.0). Suicide survivors were overrepresented among distressing NDErs (24% vs. 1%, p < .001). Bayesian analyses showed decisive evidence for lower affective scores (BF₁₀ = 42.3) but no differences on cognitive, paranormal, or transcendental components. Memories were equally vivid and detailed as classical NDEs.

In vitro experimental study testing whether 'stored' or 'recorded' healing intention (the Bengston method) induces transcriptional changes in breast cancer cells. Three delivery methods were compared: cotton charged by trained healers, an electromagnetic recording (R18) of 3 healers captured on 38 channels in a Faraday chamber, and direct hands-on treatment. Of 167 genes screened by qRT-PCR, 68 showed significant changes (p<0.05) when cells were exposed to R18, with 37 exceeding 1.5-fold change. ATP citrate lyase (ACLY) was consistently downregulated at 4 hours across 3 independent experiments (fold: −1.35 to −2.11, p=.011 to .00007), and IL-1β was consistently downregulated at 24 hours (fold: −1.73 to −1.61, p<.004). Hands-on delivery produced faster and stronger effects. ACLY and IL-1β are proposed as candidate biomarkers of the healing method.

This study tested a novel neurobiological model proposing that frontal brain systems act as a filter to inhibit psi, with inhibitory mechanisms related to self-awareness. Two participants with frontal lobe damage performed mind-matter interaction tasks using a portable Random Event Generator (REG) from the PEAR lab. Case 1: 68-year-old female with behavioral variant frontotemporal dementia (bilateral frontal damage, C9ORF72 mutation). Case 2: 55-year-old male with large left frontal tension pneumocephalus. Task: influence REG output (200 bits/sec) translated into arrow movement on computer screen (right/left intention, baseline). Each intention: 1000 trials; control runs without participant/experimenter. MRI analyzed for frontal volume loss. Results: Both participants showed significant effects for intention right vs control (Case 1: t=-2.16, p=.03; Case 2: p=.0015, replicated p=.0115), but not for left or baseline intentions. Effects lateralized contralateral to lesion side. Effect sizes 4-15x larger than normal participants. Primary lesion overlap: left medial middle frontal region (Brodmann areas 9, 10, 32) - 33% damage Case 1, 17% Case 2. REG passed NIST randomness tests. Conclusions: Medial frontal lobes may act as biological psi-inhibitory filter via self-awareness mechanisms. Damage to this region may enhance psi abilities.

On statistical grounds, the authors argue that extremely small effect sizes in precognition meta-analyses do not exceed the 'crap factor' — systematic measurement artifacts inherent in psychological experiments — and that standard null hypothesis testing is biased toward rejection with increasing sample sizes. On theoretical grounds, Hooper argues that nothing in special/general relativity, quantum mechanics, or quantum field theory permits retrocausal information transfer, and any such mechanism would violate the second law of thermodynamics. The authors propose transliminality and intuitive thinking as conventional neuropsychological explanations for apparent presentiment effects.

Precognition as a Form of Prospection: A Review of the Evidence

Reviewing controlled experiments across five domains — precognitive dreaming, forced-choice conscious precognition, free-response precognition, implicit (Bem-style) precognition, and physiological presentiment — this paper evaluates whether precognition represents a genuine form of human prospection. The forced-choice literature (309 studies, 1935-1987) yields ES = 0.02, Z = 6.02, p = 1.1x10^-9. Implicit precognition (90 experiments) shows Hedges' g = 0.09, p = 1.2x10^-10, with fast-thinking tasks driving the effect. The presentiment meta-analysis (26 studies) reports ES = 0.21, z = 5.3, p = 5.7x10^-8. The authors conclude converging evidence challenges standard assumptions about temporal causality.

Intravenous DMT (7–20 mg) was administered to 13 healthy volunteers in a within-subjects, placebo-controlled, single-blind study to test whether the psychedelic experience overlaps phenomenologically with near-death experiences (NDEs). Using the Greyson NDE scale as the primary outcome, all 13 participants scored above the NDE threshold (≥7) after DMT, with a massive effect (t = 10.91, p = 1.39×10⁻⁷, d = 3.09). Ten of 16 NDE items reached significance after correction. Comparison with a matched sample of 13 actual NDE experiencers revealed comparable total scores (d = 0.49, p = 0.089), with only 'point of no return' differing significantly. NDE scores correlated strongly with ego dissolution (r = 0.69) and mystical experience (r = 0.90). Baseline delusional ideation predicted NDE intensity. These results demonstrate striking phenomenological overlap between DMT experiences and actual NDEs.

Under double-blind conditions, psilocybin (30 mg/70 kg) produced complete mystical experiences in 57-67% of participants, with effects persisting at 14-month follow-up. The psychometrically validated 30-item Mystical Experience Questionnaire (MEQ30) captures four factors: Mystical, Positive Mood, Transcendence of Time and Space, and Ineffability. Mystical experience scores mediated therapeutic outcomes in addiction and cancer-related distress. Proposes a functional neural model in which disruption of the default mode network — particularly decreased activity in the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus — underlies the unity and timelessness central to mystical experience, drawing parallels with meditation neuroimaging.

This paper critically examines 17 years of Global Consciousness Project (GCP) data (1998-2015, 491 pre-registered events, 50-60 RNGs worldwide, 26+ billion trials). The cumulative result rejects the null hypothesis by 7 standard deviations (mean event z=0.316±0.045, P<10^-12). However, Bancel argues this cannot support a simple global consciousness (GC) field model due to XOR processing in RNGs (which blocks pre-XOR correlations) and inadequate network timing synchronization (1-second accuracy vs required 100 microseconds). Four tests of self-referential fine-tuning (SFT) favor goal-oriented (GO) psi interpretation: (1) surrogate Earth/Peace days not registered showed null (z=0.01) vs registered days (z=0.65); (2) variance statistic significant only for its designated events; (3) variance peaks at exactly 15-minute blocking as specified; (4) correlations decline with timestamp shifts. Conclusion: GCP demonstrates goal-oriented PK associated with experiment-engaged individuals, not collective consciousness. Effect size constant over 17 years despite quality improvements.

Short commentary responding to Iso-Ahola (2017) who argued that falsifiability and replication are of secondary importance to scientific progress and that psychological phenomena are inherently not fully reproducible because humans are irreducibly complex. Heino, Fried, and LeBel counter that complexity should motivate more sophisticated study designs (person-level time series, within-person repeated measures) rather than abandoning replicability standards. They argue that falsification is what makes science self-correcting, and that without rigorous direct replications psychology turns into astrology. They cite successful complexity science in ecology, biology, and physics as evidence that complexity and replicability are compatible.

Drawing on firsthand experience exposing the W. J. Levy fraud at J. B. Rhine's lab and two decades of work in FDA-regulated pharmaceutical research, Kennedy argues that standard post hoc investigations of fraud are uniquely ineffective in parapsychology because statistical anomalies indicative of data manipulation can be explained as psi effects. The Levy case required direct covert detection during an ongoing experiment — a 'sting operation' — to produce compelling evidence. Kennedy advocates adopting the pharmaceutical research standard that fraud by one experimenter should be very difficult or impossible, implemented through duplicate data records, dual-experimenter oversight, and documented software validation. This systematic prevention approach would eliminate the vast majority of fraud cases and is preferable to reliance on after-the-fact accusations and investigations.

Scientists should be able to provide support for the absence of a meaningful effect, but nonsignificant p-values cannot establish this. This tutorial introduces the two one-sided tests (TOST) procedure for equivalence testing: researchers specify upper and lower equivalence bounds based on the smallest effect size of interest (SESOI), then test whether observed effects fall within this range. Formulas and worked examples are provided for independent/dependent t-tests, correlations, and meta-analyses. An accompanying spreadsheet and R package (TOSTER) enable psychologists to perform equivalence tests and power analyses. Adopting equivalence testing prevents misinterpreting nonsignificant results as evidence for the null, enables replication studies to test for absence of meaningful effects, and encourages researchers to specify which effect sizes they find theoretically worthwhile.

Mixed-methods investigation of meditation-related experiences in Western Buddhist practitioners, with deliberate focus on underreported challenging, difficult, distressing, or functionally impairing effects. Qualitative interviews with 60 practitioners (20 each from Theravāda, Zen, Tibetan traditions) and 32 experts yielded a taxonomy of 59 meditation-related experiences across 7 domains (cognitive, perceptual, affective, somatic, conative, sense of self, social) and 26 influencing factors across 4 domains (practitioner-level, practice-level, relationships, health behaviors). Valence ranged from very positive to very negative; 73% reported moderate-severe impairment, 17% suicidality, 17% hospitalization. Causality assessment met WHO/FDA criteria (mean 4.2/6). Findings challenge assumptions that meditation difficulties only occur in vulnerable populations or intensive practice contexts.

Participants completed the Greyson NDE scale and Memory Characteristics Questionnaire (MCQ). Greyson total score positively correlated with MCQ total score (r=0.29, p<0.0005), indicating more intense NDEs have richer memory phenomenology. Specific associations found for sensory details, personal importance, and reactivation frequency. No associations with time since NDE, suggesting memory characteristics remain stable over time (mean 23 years).

Decline Effects: Types, Mechanisms, and Personal Reflections

Protzko, John & Schooler, Jonathan W • 2017

Non-Empirical

A taxonomy of four types of declining effect sizes in science: false positive (no true effect; e.g., Mozart effect), inflated (true effect exaggerated by small N and selective reporting), under-specified (true effect but boundary conditions unknown), and genuinely decreasing (true effect diminishes over time with variables held constant). General mechanisms include underpowered studies, publication bias, and selective reporting. Schooler reports his verbal overshadowing effect declined from ~25% impairment to markedly smaller effects in a 30-lab registered replication. Protzko argues most genuinely decreasing effects are Type I errors of a mega-analytic framework. Both advocate pre-registration and prospective multi-site replication.

This meta-analysis examines dream-ESP studies from 1966-2016, testing whether dream content corresponds to randomly selected target material more often than chance. The homogeneous dataset (50 studies, 1,968 trials, 734 hits) yielded mean ES=0.20 (SD=0.31), Stouffer Z=5.32, p=5.19×10^-8, with 95% CI [0.11, 0.29]. Maimonides Dream Laboratory (MDL) studies (n=14) showed mean ES=0.33; non-MDL studies (n=36) showed mean ES=0.14, but the difference was non-significant, t(48)=1.97, p=.055. No significant differences emerged between ESP modalities (telepathy/clairvoyance/precognition), REM vs non-REM monitoring, or dynamic vs static targets. Bayesian parameter estimation (50,000 MCMC iterations) confirmed frequentist results: 95% HDI for ES=[0.03, 0.20], null rejected. Quality ratings (two blind judges, alpha=.84) averaged 0.64/1.00, with quality-ES correlation non-significant (r=.09, p=.527). However, ES declined over time (r=-0.29, p=.044) while quality improved (r=0.39, p=.006). Fail-safe N=110 unpublished studies would be needed to nullify results.

Examines the popular claim that the pineal gland secretes N,N-dimethyltryptamine (DMT) in amounts sufficient to produce near-death and out-of-body experiences. Reviews the biochemistry of indolethylamine N-methyltransferase (INMT), DMT receptor binding affinities, dose-response data from human IV studies, and evidence for brain accumulation. The adult pineal weighs <0.2 g and produces only ~30 µg/day of melatonin; producing the ~25 mg DMT needed for psychoactive effects is implausible by three orders of magnitude. No credible evidence supports active DMT accumulation in neurons. Alternative mechanisms—dynorphin/kappa-opioid activation, massive neurotransmitter surges during asphyxia (norepinephrine >30-fold, serotonin >20-fold), and glutamate excitotoxicity—more parsimoniously explain near-death altered states.

Retrospective meta-analyses resemble exploratory rather than confirmatory research because inclusion criteria, statistical methods, and moderator decisions are made after analysts know study outcomes. Three options for prospective meta-analysis are compared: (1) preregistered plans, still allowing retrospective decisions about unanticipated variations; (2) preplanned multi-center projects, optimal but requiring funding rarely available in behavioral science; (3) registration-based prospective meta-analysis, where inclusion/exclusion of independently-initiated studies is decided at pre-registration, before data collection. An exemplar applying Option 3 to ganzfeld ESP studies at the Koestler Parapsychology Unit illustrates the approach.

Using Monte Carlo simulations and a genetic algorithm, a method was developed to quantify the impact of Questionable Research Practices (QRPs) on meta-analytic results. Applied to 78 post-1985 Ganzfeld telepathy experiments (3,494 trials, mean hit rate 31% vs. 25% chance), seven QRPs were modeled at prevalence rates from published surveys of psychologists. With realistic QRP parameters and no anomalous effect, simulations failed to reproduce the empirical database (F=10.15, p<0.05). Allowing a 2% excess hit rate yielded acceptable fit (F=1.79, p=0.47). QRPs explain approximately 60% of the reported effect size, but a residual effect remains significant (p=0.003).

Across three studies, strong psychic believers and strong skeptics (screened from 2,541 adults using a modified Australian Sheep-Goat Scale, matched on age, sex, and education) completed multiple cognitive tasks. No consistent group differences emerged on episodic memory distortion (DRM false recall, criterial recollection, imagination inflation) or working memory. However, skeptics reliably outperformed believers on Shipley Logic (pooled d = 0.46) and Vocabulary (d = 0.62), and believers disproportionately endorsed conspiracy theories (interaction eta-squared = .104, pBIC > .99). Believers also reported higher dissociative experiences (d = 0.84) and absorption (d = 1.30). Both groups equally endorsed Darwinian evolution, and psychic belief positively predicted life satisfaction (beta = .19, N = 2,541).

Prompted by Bem's (2011) 'feeling the future' experiments, psychology recognized the need for pre-registered confirmatory research. Eight additional methodological deficiencies remain unaddressed in both fields: deficient study registration, bias from dropouts and incomplete data, lack of software validation, absence of fraud prevention measures, inappropriate statistical methods for confirmatory studies, overlooked Bayesian inferential errors, weaknesses of retrospective meta-analysis versus prospective meta-analysis, and statistical dependence problems in outcome variables. Drawing on regulated medical research standards (FDA clinical trial guidance), specific practices are recommended for each deficiency. When confronted with the choice between psi and methodological flaws, psychologists will inevitably choose reform — making proactive adoption of these standards the efficient path forward.

An online experiment tested whether conscious attention directed toward a distant double-slit optical system could modulate the interference pattern fringe visibility, following von Neumann's proposal that an extra-physical factor is involved in quantum measurement. Over 2013-2014, 1,479 participants from 77 countries contributed 2,985 test sessions while 5,738 automated robot sessions served as controls. Participants alternated 30-second concentration and relaxation epochs, receiving real-time feedback linked to the double-slit spectral component. Combined analysis showed fringe visibility deviated from null by z = 5.72 (p = 1.05 x 10^-8), conforming to observers' intentions. Control sessions showed z = 0.17 (p = 0.86). A serendipitous feedback-coding error between years reversed the direction of effect, providing evidence for active intentional steering rather than passive observation.

EEG Correlates of Social Interaction at Distance

Investigates whether EEG activity in a sensorily isolated 'receiver' correlates with stimulation experienced by a distant 'sender'. Six meditation-experienced participants formed 25 sender-receiver pairs over three days. Senders received 128 light-and-audio stimulations; receivers sat in separate soundproofed rooms. Traditional ERP averaging found a clear response in senders but nothing in receivers. A novel inter-electrode correlation algorithm (GW6) detected a weak but significant receiver response in the 9-10 Hz alpha band (p = 0.002-0.003, Monte Carlo) and at 8-12 Hz (p = 0.04). Effect was approximately 0.5% correlation change. Receiver latency of ~700 ms suggested tracking of the sender's altered state rather than the stimulus.

Integrated information theory (IIT) starts from five phenomenological axioms — intrinsic existence, composition, information, integration, and exclusion — and derives postulates about the physical substrate of consciousness (PSC). The PSC is the complex of neural elements specifying a conceptual structure with maximum integrated information (Phi_max). IIT explains why the cortex supports consciousness but the cerebellum (with 4x more neurons) does not, why consciousness fades during slow-wave sleep despite continued neural activity, and predicts that consciousness can split in split-brain patients. The perturbational complexity index (PCI), validated across sleep, anesthesia, and brain damage, serves as a practical proxy for Phi_max.

Examining epistemological implications of near-death experiences and other non-ordinary mental expressions (NOMEs), this paper critiques proposed neurobiological NDE explanations — retinal ischemia, endogenous opioids, temporal lobe epilepsy, NMDA receptors, and REM intrusion — finding each unsupported by clinical evidence. NDE incidence is 10-18% in critical-condition patients; NDE memories show theta-band EEG consistent with true episodic memory. The authors trace the mechanist-reductionist paradigm to Galileo and Descartes, proposing to replace the 'altered states of consciousness' framework with NOMEs, integrating first-person and third-person perspectives per Varela's neurophenomenology.

Six methodological and analytical objections to predictive anticipatory activity (presentiment) raised by Schwarzkopf (2014) are addressed point by point. Removing questioned studies from the original meta-analysis (Mossbridge et al. 2012) still produced overwhelmingly significant results. Simulation of expectation bias detection across 1000 experiments showed ~92% of effects could not be explained by expectation bias (r = -0.16, p > 0.524 between effect size and sample size). Stimulus ratio imbalance (2:1 or 3:1 neutral-to-emotional) actually works against finding presentiment effects. Baseline correction via z-transformation is methodologically appropriate, and higher-quality studies produced larger effect sizes. The authors propose that presentiment may reflect time-symmetric processes consistent with known microscopic physics.

Cognitive psychology findings replicated better (50%) than social psychology (25%). Replication success correlated with original evidence strength rather than replication team characteristics, implicating publication bias and analytic flexibility as likely contributors to inflated original effects.

Consciousness: here, there and everywhere?

Tononi, Giulio & Koch, Christof • 2015

Non-Empirical

Integrated Information Theory (IIT 3.0) is presented as a principled framework for understanding consciousness. Starting from five phenomenological axioms — intrinsic existence, composition, information, integration, and exclusion — IIT derives postulates about the physical substrates required for experience. The theory identifies consciousness with maximally irreducible integrated information (Phi_max), explaining why the cerebral cortex supports consciousness while the cerebellum, despite having four times as many neurons, does not. IIT predicts that feed-forward networks are unconscious regardless of computational sophistication, that digital simulations of conscious brains would not themselves be conscious, and that consciousness is graded and widespread among biological organisms. The perturbational complexity index (PCI), inspired by IIT, reliably tracks consciousness across sleep, anaesthesia, and brain injury.

Seven meta-analyses evaluated the robustness of religious priming effects across 93 studies (N = 11,653). Using effect-size analyses, p-curve analyses, and trim-and-fill publication-bias corrections, the review examined whether religious priming reliably alters psychological outcomes, promotes prosocial behavior, and extends to non-believers. Overall priming produced g = 0.40 (p < .0001), reduced to g = 0.29 after bias correction. Prosocial effects were smaller (g = 0.27, adjusted g = 0.18) but robust. P-curve analyses confirmed evidentiary value over p-hacking. Effects were confined to religious participants (g = 0.44) with no reliable effect on non-believers (g = 0.04, p = .71), suggesting priming depends on activation of culturally transmitted beliefs rather than universal low-level associations.

Introduces the "small telescopes" approach for evaluating replication results: instead of asking whether a replication effect is significantly different from zero or from the original estimate, the method tests whether it is significantly smaller than d33% — the effect size giving the original study only 33% power. Applied to three replication disputes, the approach shows that underpowered replications (e.g., Gamez et al. with 44% power) can be uninformatively noisy, while large well-powered replications can reject the original design's adequacy even when the replication finds a significant effect. A simple rule emerges: replications need approximately 2.5x the original sample size for 80% power to reject d33%.

This retrospective study used the Greyson NDE scale to compare 190 self-reported near-death experiences: 50 'NDE-like' experiences from non-life-threatening events (sleep, syncope, meditation, drugs) and 140 'real NDEs' from coma survivors (anoxic n=45, traumatic n=30, other n=65). NDE intensity and content did not differ between NDE-like and real NDE groups (total score 17+/-7 vs 16+/-6, p=0.10), nor within the real NDE group across coma etiologies (p=0.29). Peacefulness was the most frequently reported feature (89-93%); only 1% reported negative experiences. Comparing retrospective anoxic data to historical prospective studies revealed significantly higher overall feature frequencies retrospectively (GEE p<0.0001), with the exception of encounters with deceased spirits which were more frequent prospectively (57% vs 27%, OR=0.27, p=0.004).

Conceptual analysis comparing Bayesian and classical (frequentist) hypothesis testing for controversial research areas such as parapsychology. Describes the philosophical differences (objective vs subjective probability), mathematical models, and practical implications of each approach. Demonstrates that a uniform Bayesian prior can bias against small effects: 5100 hits in 10000 trials yields classical p=.046 but Bayesian BF=10.8 for the null. Recommends the FDA guidance on Bayesian clinical trials as a framework for confirmatory psi experiments: specify priors, acceptance criteria, operating characteristics (Type I error and power), and relative roles of priors vs data prospectively. Argues that both approaches are valid when properly applied, but psychology and parapsychology lack confirmatory methodology, undermining both statistical traditions.

Seven double-blind experiments investigated whether masked negative stimuli presented 500 ms after a response could retroactively influence unconscious key-press selections, as predicted by the Orch-OR quantum-mind model. Using IAPS images and a simultaneous two-key press paradigm, four of seven studies found significant avoidance of negative future outcomes (Study 1: N=111, d=0.25; Study 2: N=201, d=0.21; Study 3: N=1222, d=0.07; Study 4 with quantum RNG: N=327, d=0.10). A meta-analysis across all seven experiments (total N≈2,970) yielded ES=0.07, z=3.79, p<.0001, with a combined Bayes factor of 293 favouring retroactive influence.

A narrative review of predictive anticipatory activity (PAA), the phenomenon whereby human physiology appears to distinguish between unpredictable future emotional vs. neutral stimuli 1–10 seconds before they occur. Drawing on a meta-analysis of 26 experiments from seven independent laboratories (fixed-effect ES = 0.21, z = 6.9, p < 2.7 × 10⁻¹²; random-effects ES = 0.21, z = 5.3, p < 5.7 × 10⁻⁸), the review critically evaluates p-hacking and expectation bias as alternative explanations, finding neither compelling. Proposes 'temporal mirroring' (pre-event responses mirror post-event responses) and discusses quantum biology and delayed conscious experience as speculative mechanisms. Concludes that PAA is a robust unconscious phenomenon with potential practical applications.

A 15-year international experiment using a global network of up to 65 hardware random number generators (RNGs) tests whether synchronized random data streams become non-random during major world events. Over 450 pre-specified formal tests using the Netvar statistic show a composite departure of approximately 7 standard deviations from expectation, with odds exceeding a trillion to one against chance. Roughly two-thirds of events show positive correlations and nearly 15% reach nominal significance (p < 0.05). Secondary analyses reveal effects concentrate in large, powerfully engaging events, vary with local time of day (larger during waking hours), and show only ambiguous distance constraints (Z ~ 1). Controls exclude electromagnetic radiation, power grid strain, and mobile phone artifacts.

This editorial introduces Registered Reports, a novel publishing format that incorporates peer review and preregistration of designs before data collection. The authors present the first known journal issue in any discipline consisting exclusively of pre-registered replication studies: a special issue of Social Psychology with 15 articles. The process involved issuing calls for proposals (36 received), peer review of full proposals (24 encouraged, 14 accepted), and OSF registration prior to data collection with publication guaranteed irrespective of results. This approach shifts incentives to evaluate methodological quality rather than results, addressing the publication bias against replications and negative results that undermines scientific credibility.

This study investigated whether NDE memories are phenomenologically and neurally distinct from imagined event memories. Ten NDE experiencers (Greyson scale ≥7) and 10 matched controls recalled real and target memories (NDE or imagined) before and after hypnotic induction. Memory Characteristics Questionnaire assessed phenomenology; 32-channel EEG recorded neural activity during recall across delta, theta, alpha, beta, and gamma bands. NDE memories showed similar detail richness to real memories and significantly more than imagined memories (p=0.021). NDE recall uniquely correlated with delta (2-3 Hz) and theta (3.5-6 Hz) band power, whereas real memories correlated with high alpha and gamma bands. Hypnosis significantly increased memory detail across all conditions (all p<0.02). Findings suggest NDE memories are stored as episodic memories of events experienced in a peculiar state of consciousness, phenomenologically indistinguishable from real memories but with distinct neural markers.

Of 2060 CA events, 140 survivors completed initial interviews and 101 completed detailed follow-ups using a three-stage quantitative and qualitative interview system. Results showed 46% had memories during CA with seven major cognitive themes, 9% had experiences compatible with NDEs on the Greyson Scale, and 2% described full awareness with explicit recall of seeing and hearing resuscitation events. One patient demonstrated verified conscious awareness for approximately 3 minutes during a period when cerebral function was not expected, accurately describing specific details confirmed by medical staff.

In Study 1, 162 participants completed Bem's retro-priming paradigm (classifying words before seeing a congruent or incongruent picture prime). Results were non-significant overall (es=0.11) but post-hoc analyses found effects for students (r=0.17, p<0.05) and males (r=0.41, p<0.01). In Study 2, the 28 highest scorers returned; retro-priming results were negative and non-significant (es=−0.25), with a significant negative correlation between sessions (r=−0.46, p<0.05). Forward priming remained robust (es=0.63). No psychological profile distinguished consistently high scorers.

Precognition claims violate the second law of thermodynamics and would invalidate baseline correction procedures fundamental to experimental research. Six objections are raised against the Mossbridge et al. (2012, 2014) presentiment meta-analysis: questionable primary study quality including circular inference in fMRI data, failure to include broader non-parapsychological literature using similar designs, neglect of ~2:1 trial imbalances enabling learned stimulus predictions, potential baseline correction artifacts from slow post-stimulus signal decay, inadequate testing of expectation bias, and biological implausibility of one neural mechanism producing precognitive effects across measures with vastly different temporal scales.

In telephone tests with 4 random callers, participants achieved 40% hit rate (N=63, 570 trials, p<10⁻¹⁰) and 45% under videotaped conditions (271 trials). Email telepathy showed 43% accuracy (552 trials, p<10⁻¹⁸); SMS telepathy 37.9% (800+ trials, p=0.001). Automated mobile phone tests yielded 56% vs 50% chance (600+ trials, p=0.001). Confidence strongly predicted accuracy (85% when 'confident'). Precognition control tests showed chance-level performance, supporting telepathy rather than precognition as the mechanism.

Argues that parapsychological phenomena lack scientific acceptance not merely due to insufficient evidence but because no adequate theoretical framework connects them to mainstream science. Proposes Generalized Quantum Theory (GQT), which extends quantum formalism to any system requiring incompatible/complementary observables. Derives three conditions for generalized entanglement correlations (GET): a system with identifiable subsystems, a global observable complementary to local observables, and an entangled state. Applies the framework to telepathy, healing, clairvoyance, psychokinesis, and precognition. The No-Transmission (NT) axiom predicts that classical experimental designs will fail in exact replications because they attempt to code nonlocal correlations as signals — explaining the decline effect in PK meta-analyses and repeated replication failures.

Pre-registered confirmatory study testing whether EEG activity of a distant 'receiver' can reflect the stimulus sequence (silence/signal) delivered to a paired 'sender' ~190 km away. Seven experienced meditators served as both senders and receivers across 20 sessions. An SVM classifier detected 78.4% coincidences (BF=390,625) between stimulus protocol and receiver EEG, and significant alpha-band (r=0.37) and gamma-band (r=0.24) correlations were observed between pairs. However, a stricter cross-participant analysis reduced positive results to only 4 of 20 pairs, and specificity controls showed similar correlations for unpaired participants. Reviewer reanalysis demonstrated the main SVM result was an analytical artifact caused by temporal autocorrelations in EEG data.

Reviews the physical plausibility of retrocausality via time-symmetric physics, Wheeler-Feynman absorber theory, and the transactional interpretation of quantum mechanics, noting no physical law precludes retrocausal information transfer. Acknowledges reliability concerns about small effect sizes and replication difficulty, drawing parallels to social priming research.

A biophysical hypothesis proposes that brilliant light perception during near-death experiences arises from bioluminescent biophoton emission caused by unregulated free radical overproduction in retinotopic visual areas during brain hypoxia and reperfusion. Rat brain studies showed ultraweak chemiluminescence rising from 11±15 to 231±35 counts/10s-g during hypoxia, with spectral peaks at 480–700 nm consistent with singlet oxygen species. The model extends to visual imagery in NDEs via REM sleep-associated dream-like biophysical picture representations from long-term visual memory stored as epigenetic codes. The authors further speculate that self-consciousness may involve low-energy quantum entanglements via biophotons, potentially persisting outside the body during NDEs.

Low statistical power in neuroscience studies reduces both the chance of detecting true effects and the probability that significant findings reflect genuine effects (positive predictive value). Analysis of 49 neuroscience meta-analyses (730 studies published in 2011) reveals median power of 21%, falling to 18% when high-power neurological outliers are excluded. Brain volume studies show median power of just 8%. An excess significance test confirms more significant results than expected (349 vs. 254, p < 0.0001), indicating reporting biases. The winner's curse further inflates initial effect estimates by 25-50% at typical power levels. These problems undermine reproducibility and waste resources, including animal lives in preclinical research. Recommendations include a priori power calculations, pre-registration, transparent reporting, data sharing, and large-scale collaborative replication.

Six Windbridge Certified Research Mediums underwent two experiments combining double-blind accuracy testing with 32-channel EEG recording. In Experiment 1, each medium was given only the first name of a deceased person and answered 25 questions during 20-second silent intervals optimized for movement-free EEG collection. Blinded sitters scored both target and decoy transcripts. Three of four evaluated mediums scored significantly above chance (M5: +46.8% accuracy difference, p < 0.00005; M1: +14.2%, p = 0.008; M2: +3.1%, Wilcoxon p = 0.004). Medium M1 showed a significant correlation between frontal theta power and accuracy (p < 0.01, cluster-corrected), with theta decreasing monotonically as accuracy increased. In Experiment 2, all six mediums showed significant EEG differences across four mental states (communication, recollection, perception, fabrication), primarily in gamma and beta bands, though gamma effects could not be distinguished from muscle artifacts.

Challenges the traditional definition of autism as a triad of deficits in social interaction, communication, and imaginative play, arguing that neurological differences in sensory and movement systems account for many behaviours previously interpreted as volitional social withdrawal. Drawing on Thelen's dynamic systems theory, neuroscience literature, and self-advocate testimonials, the paper proposes that difficulties initiating, stopping, or switching sensation and movement underlie the social presentation of autism. Motor skill at age 2 is the strongest predictor of losing the autism diagnosis by age 4. Recommends accommodation of sensory-movement differences rather than behavioural control.

IPA of the 3 NDE experiencers revealed four themes: unique light visions, intense emotions, helplessness, and supernatural-but-rational interpretations.

One twin received five randomly-timed shock/surprise stimuli while the isolated twin was monitored via polygraph. A blinded expert used forced-choice to identify stimulus windows. Six hits occurred out of 24 assessed trials versus three expected by chance (P = 0.07, one-tailed). One twin pair produced four hits in seven trials.

No physiological, psychological, or pharmacological variable predicted NDE occurrence.

Continuous six-channel EEG recordings in nine rats revealed that cardiac arrest triggers a transient (~30 s) surge of highly organized gamma oscillations before isoelectric EEG. Low-gamma (25–55 Hz) power during the near-death state exceeded 50% of total EEG power (vs. <5% waking; P < 0.0005), with global coherence more than doubling relative to waking (P < 0.001). Directed connectivity via normalized symbolic transfer entropy showed feedback (top-down) low-gamma connectivity eight-fold above waking levels (P < 0.0001). Phase-amplitude coupling patterns paralleled signatures of conscious visual processing. CO2 asphyxiation produced comparable results, ruling out pain artifacts.

The CEMI Field Theory: Closing the Loop

McFadden, Johnjoe • 2013

Non-Empirical

Synchronous neuronal firing is the strongest known correlate of attention, awareness, and consciousness, yet when EM field theories of consciousness were first proposed around 2002 there was no direct evidence that synchrony was functional or that endogenous EM fields influenced neuron firing. Three key studies have since closed that evidential gap: Fujisawa et al. (2004) showed externally applied 40 Hz fields modulate hippocampal neuron firing; Frohlich & McCormick (2010) demonstrated that endogenous fields as weak as 0.25 mV/mm entrain neocortical oscillations; and Anastassiou et al. (2011) proved ephaptic coupling causes phase-locked synchronous firing. Together these establish a feedback loop — neurons generate coherent EM fields that in turn recruit more neurons into synchrony — supporting the CEMI field theory's claim that the brain's EM field is the physical substrate of consciousness.

Editorial commentary comparing Stefan Schmidt's meta-analysis of distant intention effects (11 studies, 576 sessions showing small but consistent effect sizes) with the Princeton Engineering Anomalies Research (PEAR) laboratory's 30-year program.

PEAR's work with random-event generators found similarly small effect sizes but with extreme statistical significance from large databases. Key PEAR findings: no attenuation by distance or time, multiple operators producing stronger effects than individuals, and operator intentions correlating with RNG deviations regardless of generation method.

Less expert mediums showed the opposite pattern with increased activation. Paradoxically, psychographed content was rated significantly more complex than control writing for the whole sample (16.8 vs 14.4, p=0.007) and experienced mediums (18.4 vs 15.4, p=0.041).

Analyzes whether the unreliability of replication in controversial psychological phenomena stems from insufficient statistical power rather than non-existence of the effects. Retrospective power analysis of meta-analyses covering four phenomena — subliminal semantic priming (d = 0.47–0.80), incubation effect (d = 0.29), unconscious thought theory (d = 0.22), and non-local perception across three protocols (d = 0.011–0.16) — reveals that except for semantic priming on categorization (power = 0.96), the typical study has power far below 0.90. Forced-choice ESP studies (d = 0.011) would require N = 3,450 participants for adequate power, yet average N = 128. Recommends alternatives to NHST including confidence intervals, equivalence testing, and Bayesian approaches.

An Agenda for Purely Confirmatory Research

Wagenmakers, Eric-Jan et al. • 2012

Non-Empirical

Argues that the pervasive confusion between exploratory and confirmatory research threatens psychological science. Proposes preregistration as the primary remedy: researchers publicly post a detailed analysis plan before testing any participants, and only pre-specified analyses qualify as confirmatory with valid statistical inference. Illustrates the proposal with a preregistered Bayesian replication of Bem's (2011) precognition experiment (N=100 women, two sessions of 60 forced-choice trials each). The replication found BF01 = 16.6 (default prior) and BF01 = 6.2 (Bem's knowledge-based prior), both strongly favoring the null hypothesis of no precognition.

Pre-registered confirmatory replication of Bem's (2011) Experiment 1, testing whether participants can detect erotic pictures behind curtains at above-chance rates. One hundred female participants each completed two sessions of 60 trials (15 erotic, 45 neutral). All methods and Bayesian analyses were specified and posted online before data collection. Six pre-specified Bayes factor tests — comparing erotic vs. neutral performance, erotic vs. chance, extraversion correlations, and cross-session consistency — all yielded evidence favoring the null hypothesis. Combined-session Bayes factors reached BF₀₁ = 16.6, providing strong evidence against precognition. A small positive extraversion-performance correlation (r = 0.13) was not supported by Bayesian analysis (BF₀₁ = 3.64).

The social motivation theory of autism

Chevallier, Coralie et al. • 2012

Non-Empirical

Argues that diminished social motivation — decomposed into social orienting, social reward (wanting/liking), and social maintaining — constitutes a primary deficit in Autism Spectrum Disorders, with downstream consequences for social cognition. Reviews behavioral evidence (reduced eye contact, social anhedonia, absent reputation management), neurobiological substrates (orbitofrontal-striatal-amygdala circuit abnormalities, disrupted oxytocin signaling), and an evolutionary framework explaining why affiliative motivation is selectively impaired while attachment and sexual drives are preserved. Concludes that boosting social attention enhances social cognitive performance, suggesting underlying competence is more intact than spontaneous behavior indicates.

Using arterial spin labeling perfusion and BOLD fMRI, two groups of 15 healthy volunteers were scanned during IV infusion of psilocybin (2 mg) versus saline placebo in a task-free protocol. Psilocybin produced only decreases in cerebral blood flow and BOLD signal, with no increases in any region. Decreases were maximal in default mode network hub regions — thalamus, anterior and posterior cingulate cortex, and medial prefrontal cortex. Greater ACC blood flow decreases predicted more intense subjective effects (r = −0.55, p = 0.017). A pharmaco-physiological interaction analysis revealed significantly decreased positive coupling between mPFC and PCC. The authors conclude that psychedelic consciousness arises from decreased activity and connectivity in connector hubs, enabling unconstrained cognition — consistent with Huxley's 'reducing valve' metaphor.

Why Science Is Not Necessarily Self-Correcting

Ioannidis, John P.A • 2012

Non-Empirical

Self-correction is widely assumed to be a defining hallmark of science, but how often does it actually occur? Reviewing empirical evidence from psychology and biomedicine, Ioannidis argues that self-correction requires active replication effort — yet only ~1% of psychology papers are replications, fewer than 0.2% are independent direct replications, and most yield confirming results (perpetuated fallacies). With average power of 35% and modest bias, unchallenged fallacies may constitute 30–95% of published significant findings. A taxonomy of six discovery–replication paradigms quantifies the problem. Thirteen impediments to self-correction are catalogued, including publication bias, selective reporting, underpowered studies, and editorial bias against replication. Proposed reforms each carry unintended risks unless pursuit of truth remains the overriding priority.

A 250-year literature survey identified 83 cases of 'terminal lucidity' — the unexpected return of mental clarity and memory shortly before death in patients with severe psychiatric and neurological disorders. Cases span brain abscesses, tumors, strokes, Alzheimer's disease, meningitis, schizophrenia, and affective disorders. Historical asylum data showed 13% of 139 deceased patients had considerably improved mental states at death; a modern nursing home study found 7 of 10 caregivers had witnessed the phenomenon. Two distinct patterns emerged: gradual improvement paralleling physical decline, and sudden full clarity just before death. The authors argue these cases, particularly those involving extensive brain tissue destruction, challenge prevailing neurological models of cognition and memory.

Qualitative investigation of sensory and movement differences from the perspective of five adults with autism. Through 40+ hours of interviews, questionnaires, and observations, participants described disruptions in perception (auditory pain, visual sensitivities), action (difficulty controlling/combining movements), posture (proprioceptive challenges), emotion (difficulty expressing/modulating feelings), communication (speech execution problems, nonverbal challenges), and cognition (intrusive thoughts, cognitive overload). Participants described behaviors typically interpreted as social deficits — such as avoiding eye contact or unusual postures — as sensory-motor accommodations. All five rejected the assumption that autistic individuals lack theory of mind, reporting nuanced emotional understanding despite expressive difficulties. The data support a view of autism as a disorder affecting motor planning, sensory-motor integration, and their dynamic interaction, rather than primarily a social-cognitive deficit.

Publication norms in academic science emphasize novel, positive results, creating incentives that inflate false-positive rates and discourage replication. Drawing on the authors' own failed replication of a provocative embodied-cognition finding (original p = .01, N = 1,979; replication p = .59, N = 1,300), the paper catalogues nine common practices that increase publishability at the expense of accuracy, including optional stopping, selective reporting, HARKing, and avoidance of direct replication. Existing remedies (negative-results journals, education campaigns, reviewer vigilance) are judged insufficient. The proposed solutions restructure incentives around open data, open methods, open workflow with pre-registration, post-publication review, and Replication Value metrics, arguing that transparency and accountability can make the abstract accuracy motive competitive with the concrete publication motive.

Identifies multiple procedural irregularities: protocols changed mid-study in Experiments 1 and 2 (after 40/100 and 100/150 participants), at least seven t-tests without correction for multiple comparisons rendering the headline p=.01 nonsignificant (~.06 after correction), ad hoc two-item stimulus-seeking scales with no psychometric validation, and deliberate use of one-tailed tests. Effect sizes correlate negatively with sample size across all nine experiments (r=-0.91).

Nine experiments (total N = 1,050 Cornell undergraduates) tested for anomalous retroactive influence by time-reversing well-established psychological effects: precognitive approach to erotic stimuli, precognitive avoidance of negative stimuli, retroactive affective priming, retroactive habituation, and retroactive facilitation of recall. Eight of nine experiments yielded statistically significant results (one-tailed), with a mean effect size of d = 0.22. Stimulus seeking, a component of extraversion, correlated with psi performance in five experiments; high stimulus seekers achieved a mean d = 0.43. Both hardware-based and software-based RNGs were used across experiments, and control simulations with random inputs yielded null results, arguing against artifacts of inadequate randomization.

A reply to Wagenmakers et al. (2011), who argued that a Bayesian reanalysis of Bem's (2011) nine precognition experiments yields no evidence for psi. Bem, Utts, and Johnson contend that Wagenmakers et al.'s diffuse Cauchy prior is unrealistic, placing 57% probability on effect sizes >= 0.8 and triggering the Lindley-Jeffreys paradox. Using a knowledge-based normal prior (90th percentile of |d| at 0.5, informed by known psychological and psi effect sizes), the combined Bayes factor across all nine experiments is 13,669 with posterior P(H0) = 7.3 x 10^-5 — extreme evidence for psi.

Near-death experiences reported during cardiac arrest and general anesthesia include enhanced mentation, veridical out-of-body perceptions, and visions of deceased persons not known to have died. Drawing on prospective studies showing 12-18% of cardiac arrest survivors report NDEs despite flat-line EEG within 10-20 seconds, a UVA case collection where 22% of NDEs occurred under anesthesia, and Holden's (2009) review finding 92% of veridical OBE reports completely accurate, this review argues that complex consciousness under conditions where neuroscience deems it impossible requires a revised cosmology. The shift from materialist reductionism to a framework including consciousness as fundamental is compared to the historical transition from classical to quantum physics.

Information consists of symbols, media for storing and transmitting the symbols, and an interpretational infrastructure that establishes meaning. Information processing in living systems includes genetics, perception, behavior, memory, learning, communication, imagination, creativity, and culture. This article summarizes and clarifies concepts pertaining to information as they emerge in scientific research on life, consciousness, quantum physics, and paranormal phenomena. After extensive research, the hypothesis that an observer can sometimes paranormally influence the outcome of quantum events lacks convincing empirical support. Current experimental results in parapsychology do not have properties of a signal in noise and cannot be convincingly distinguished from methodological bias. The findings may be most consistent with a model where paranormal phenomena result from supernatural information processing agencies with relatively independent motivations that manifest as spirituality and influence the meaning and direction of an individual's life.

Critique of the Bösch, Steinkamp, and Boller (BSB, 2006) PK meta-analysis in Psychological Bulletin, which concluded micro-PK evidence was attributable to publication bias. Examination of BSB's original SPSS data files reveals the database included at least 40 ESP (mainly precognition) studies despite being limited to PK, contained fabricated z-scores and arbitrarily coded control data, and excluded substantial portions of the PEAR database. The entire negative overall z-score (z = −3.67) resulted from three PEAR MegaREG studies using a potentially malfunctioning high-speed RNG contributing ~100× more trials than all other studies combined; without these three studies, z = +3.59.

Bem's (2011) nine-experiment report of evidence for psi is used as a diagnostic case study for three systemic deficiencies in modal research practice (MRP) in empirical psychology: (a) overemphasis on conceptual rather than close replication, which allows failed extensions to be filed away while successful ones count as replications; (b) failure to independently verify measurement instrument integrity, with no reliability estimates reported for any dependent variable; and (c) flawed NHST implementation that tests against a nil hypothesis virtually guaranteed to be false, making rejection contingent only on sample size (e.g., a 51.7% hit rate reaching p < .05 at N = 150). These deficiencies produce an 'interpretation bias' that buffers any theory from falsification. Conservatism in theory choice favors revising beliefs about MRP over revising beliefs about causality and time.

Approximately 3% of Americans report near-death experiences (NDEs), which classically involve out-of-body sensations, a tunnel of light, encounters with deceased persons, and feelings of bliss. This concise review argues that each NDE feature maps onto known neuroscience: tunnel vision and bright light are attributed to retinal ischemia and peripheral-to-foveal cortical disinhibition; out-of-body experiences to disruption of the right temporoparietal junction (Blanke et al. 2002 stimulation studies); the sense of being dead to Cotard syndrome (right parietal damage); encounters with the deceased to expectation-driven dopaminergic hallucinations (as in Parkinson's disease); and life review and REM components to locus coeruleus-noradrenaline activation. Positive emotions may reflect endogenous opioid and dopamine release under extreme danger. The authors conclude that no paranormal explanation is needed.

A Bayes Factor Meta-Analysis of Bem's ESP Claim

Rouder, Jeffrey N & Morey, Richard D • 2011

Minimal MA

Bayesian meta-analysis of the nine experiments in Bem's (2011) 'Feeling the Future' paper, using a newly developed meta-analytic extension of the JZS default Bayes factor t-test. Excluding three retroactive mere-exposure experiments as uninterpretable, the remaining data were categorized by stimulus type. Evidence for ESP with erotic stimuli was slight (BF = 3.23), with neutral stimuli negligible (BF = 1.57), but with emotionally valenced nonerotic stimuli noteworthy (BF = 38.7). The analysis also demonstrated that simply multiplying individual Bayes factors across experiments — as Wagenmakers et al. (2011) implicitly did — systematically underestimates cumulative evidence. Despite the BF of ~40 for emotional stimuli, the authors argued this is insufficient to overcome appropriate prior skepticism about ESP given the absence of plausible physical mechanisms.

Tressoldi analyzes seven databases covering six experimental protocols: ganzfeld free-response, remote viewing, dream-ESP, presentiment/anticipatory responses, implicit precognition, and forced-choice ESP. Using both frequentist meta-analysis (weighted effect sizes) and Bayesian meta-analysis (Bayes factors), the paper evaluates whether cumulative evidence meets 'extraordinary evidence' standards. Frequentist analysis rejects the null for all protocols (effect sizes d=0.007-0.28). Bayesian analysis shows strong evidence for H1 in three protocols: ganzfeld (BF=18.8 million), remote viewing (BF=25.4 billion), and anticipatory responses (BF=2.89×10^13).

Orchestrated objective reduction (Orch OR) proposes that consciousness arises from quantum computations in microtubule protein polymers within brain neurons, terminated by an objective reduction of quantum states linked to quantum gravity and spacetime geometry. Building on Penrose's argument that human understanding requires non-computable processes (via Gödel's theorem), and Hameroff's models of microtubules as molecular automata, the theory posits that quantum superpositions of tubulin states evolve until reaching a Diósi–Penrose gravitational threshold (τ ≈ ℏ/EG), producing discrete moments of conscious awareness at roughly gamma synchrony frequencies (~40 Hz). The authors review and respond to criticisms including Tegmark's decoherence calculations, and cite emerging evidence for warm quantum biological processes in photosynthesis, bird navigation, and preliminary ballistic conductance in microtubules.

'Peak in Darien' experiences — near-death visions in which dying persons see recently deceased individuals whose death was unknown to anyone present — are reviewed across historical and contemporary cases from the 1st century AD (Pliny the Elder) through 2008 (Sartori). Cases are classified into three types with increasing evidential weight: deceased thought to be alive, deceased who died immediately before the vision, and deceased unknown to the experiencer. From a collection of 665 NDEs at the University of Virginia, 138 (21%) included encounters with deceased persons versus only 25 (4%) with living persons. These cases challenge the expectation/hallucination hypothesis and are argued to provide some of the strongest evidence for survival of consciousness after bodily death.

Responding to Storm, Tressoldi, and Di Risio's (2010) meta-analysis of ganzfeld studies, this commentary argues that meta-analytic aggregation manufactures apparent consistency from fundamentally heterogeneous data. The original ganzfeld database's significant hit rate derived almost entirely from four experimenters (44% hit rate) while others obtained chance-level results (26%). The autoganzfeld's significance came only from dynamic targets (37%), with static targets at chance (~26%), constituting a failed replication of the original static-target database. Autoganzfeld II, meeting all of Storm et al.'s criteria for a reliable study, yielded hit rates of 26.5% (N=151) and 25.8% (N=209) — chance level.

Arguing that abandoning mediumship research due to the survival/super-psi impasse was a self-inflicted wound on psychical research, this essay reviews three historically important types of mediumistic evidence: cross-correspondences, drop-in communicators, and proxy sittings. Detailed case studies from the 1920s-1930s demonstrate that proxy sittings with Mrs. Leonard and other mediums produced highly specific veridical information unknown to the proxy. Saltmarsh's controlled study found real sitters' scores over 12 times higher than controls across 19 proxy sittings, and Kelly & Arcangel's modern study with 9 mediums and 40 sitters yielded p < .0001 using global scoring. Proxy sittings are proposed as the most productive direction for renewed research.

Study 1 (N=21, office setting) yielded 26.7% hit rate (chance = 25%, ns). Study 2 (N=8, home setting with email pre-screening) yielded 30% (p = .15). One exceptional participant scored 10/20 in Study 2 and continued in Study 3, achieving 24/60 correct (40%, p < .01, h = 0.32). Across 80 trials this participant hit 42.5% (p = .00015). Overall results driven entirely by one individual; no group-level anomalous cognition detected.

An Automated Test for Telepathy in Connection with Emails

Sheldrake, Rupert & Avraamides, Leonidas • 2009

Low Rigor

This study investigated whether people can sense telepathically who is about to send them an email before they receive it, using a fully automated online testing procedure. Participants aged 12 to 66 registered via Rupert Sheldrake's website, providing the names and email addresses of three contacts. The automated system selected a contact at random, asked that contact to send an email message to the subject through the system, and then asked the subject to guess the sender's name before delivering the message. Tests consisted of 6 or 9 trials. In a total of 419 trials, there were 175 hits (41.8%), significantly above the 33.3% chance level (p = .0001; Cohen's d = 0.2). Complete tests (37 tests, 276 trials) showed a hit rate of 38.4% (p = .03), while incomplete tests showed 48.3% hits (p = .0001), with incomplete tests scoring significantly higher than complete tests (p = .05). Analysis of response delays revealed hit rates of 42.2% for delays under 3 minutes (p = .01), dropping to chance (32.1%) for 3-10 minute delays, then rising to 45.6% for delays over 10 minutes. Male subjects (265 trials) scored 43.4% and female subjects (154 trials) scored 39.0%, with no significant sex difference. The highest hit rates by age group were in the 20-29 year cohort (52.9% from 102 trials). The effect size (d = 0.2) was notably smaller than in previous supervised telephone telepathy experiments (d = 0.5) and simultaneous email telepathy tests (d = 0.5), consistent with the authors' prior hypothesis. The study authors attribute the lower effect size to two factors: subjects were not pre-selected for apparent telepathic sensitivity, and crucially, the automated system introduced unavoidable delays between sending and guessing, meaning subjects were not guessing simultaneously while the sender was focusing on them. The study demonstrates the feasibility of automated email telepathy testing while also revealing its limitations compared to real-time supervised protocols.

A Rapid Online Telepathy Test

Sheldrake, Rupert & Beharee, Ashwin • 2009

Low Rigor

In an automated online telepathy test, each participant had four senders (two actual, two virtual). Computer selected one sender at random per trial; sender composed message for 30 sec, then participant guessed sender identity. In 6,000 trials across 500 tests, hit rate was 26.7%, significantly above 25% chance (p=0.002, d=0.03). Videotaped tests showed similar results (27.3%, p<0.01). Hit rate with actual senders was 33.7% vs. 19.5% with virtual senders, but strong guessing bias toward actual senders (62.9% of guesses) eliminated this difference when corrected. Hit rates declined with repeated testing (45.2% → 35.2% → 24.4% → 15.5%). Highest hit rates occurred at distances >500 miles. One exceptional subject (AF) maintained above-chance performance across multiple filmed tests.

Automated online experiment testing telepathy with SMS messages. 886 trials with participants aged 11-72; computer randomly selected one of three contacts to send a message, subject guessed sender before receiving message. Overall hit rate was 37.9% (336/886), significantly above 33.3% chance (p=.001, d=0.10). Incomplete tests showed 38.4% hit rate, ruling out optional stopping. Five high-scoring subjects retested under filmed conditions: 44.2% (19/43, p=.09). Effect size smaller than telephone (d=0.45) and email (d=0.50) telepathy experiments, attributed to unsupervised design and asynchronous timing.

Systematic review and meta-analysis of 21 surveys asking scientists about research misconduct, with 18 surveys pooled quantitatively. A random-effects meta-analysis found that 1.97% (95%CI: 0.86–4.45) of scientists admitted fabricating, falsifying, or modifying data at least once, while up to 33.7% admitted questionable research practices. Surveys about colleagues yielded higher rates: 14.12% (95%CI: 9.91–19.72) reported observing falsification and up to 72% observed QRPs. Three methodological factors—self vs. non-self reports, mailed vs. handed surveys, and use of explicit fraud terminology—explained 82% of between-study variance. Medical researchers reported significantly more misconduct. The author concludes these figures are conservative lower bounds.

Systematic review of 10 randomised controlled trials (N=7,646) evaluating whether intercessory prayer added to routine care improves health outcomes. Searched 10 databases including MEDLINE, EMBASE, and ATLA Religion Database through June 2007. Found no clear effect of prayer on death (5 RCTs, RR 1.00, 95% CI 0.74-1.36), clinical state (5 RCTs, RR 0.98, CI 0.86-1.11), CCU readmission (4 RCTs, RR 1.00, CI 0.77-1.30), or rehospitalisation (2 RCTs, RR 0.93, CI 0.71-1.22). Of 33 specific complications, 3 marginally favoured prayer but likely reflect multiple testing. Awareness of being prayed for was associated with more complications (RR 1.15, CI 1.04-1.28).

Replication of Wackermann et al.'s (2003, 2004) EEG correlation paradigm at IGPP Freiburg with a different experimenter. Seventeen pairs of related subjects were tested in acoustically and electromagnetically shielded rooms 8 meters apart; one subject viewed checkerboard reversals while the other relaxed. Critical review of the original bootstrap sampling method revealed it systematically overestimates effects (false positive rate 20.1-26.2% at nominal alpha = 0.05). A corrected nonparametric method with Monte Carlo correction for inter-channel dependence yielded no significant results across any of six tests (all p > .067). The original uncorrected method applied to the same data would have produced apparently significant results (1000 ms window: p = .038 uncovered, p = .0003 difference).

The GCP Event Experiment: Design, Analytical Methods, Results

Bancel, Peter A & Nelson, Roger D • 2008

Non-Empirical

Reports a decade-long experiment measuring output deviations from a global network of physical random number generators (RNGs) during major world events. The Global Consciousness Project (GCP) hypothesizes that coherent attention or emotional response of large populations corresponds to characteristic deviations in network output. Analysis of 236 formal events (1998-2008) using pre-registered variance statistics found cumulative significance of Z = 4.55 (p = 3 × 10⁻⁶). The effect is driven by inter-RNG correlations at 1-second timescale across global distances, not by individual RNG deviations. Mean event effect size = 0.296 sigma, with no outliers; modeling suggests 67% of events show positive deviations.

Using Neuroimaging to Resolve the Psi Debate

Moulton, Samuel T & Kosslyn, Stephen M • 2008

Low Rigor

Sixteen sender-receiver pairs (including identical twins, couples, and close friends) completed a forced-choice fMRI paradigm at Harvard. Receivers viewed 240 IAPS picture pairs in a 3T scanner while senders in a separate room attempted to transmit the designated target. Behavioral guessing was at exact chance (50.0%, 3,687 trials). Group-level fMRI analysis found no significant difference between psi and non-psi stimuli, despite control analyses confirming the method could detect subtle arousal effects (high vs. low arousal: p = 9.35 x 10^-21). The single participant showing apparent psi activation was explained by stimulus content confounds via permutation simulation.

Seventy-two participants in 36 couples (38 usable sessions) took part in a DMILS experiment where a sender directed compassionate intention toward a receiver in an electromagnetically shielded chamber 20 meters away. Skin conductance was measured during randomly timed 10-second intention epochs. Three groups were compared: trained (12 cancer couples, partner given 3 months compassionate intention meditation training), wait-list (10 cancer couples before training), and control (14 healthy couples, no training). Overall receiver SCL at stimulus offset was significantly elevated (z = 3.9, p = .00009, two-tailed). Per-session effect sizes for the motivated groups (e = 0.74) were 6.7x larger than prior DMILS meta-analytic estimates, though the between-group difference was not significant.

Nested ANOVA: treated crystals rated significantly more beautiful (p=0.03); planned treated vs proximal comparison p=0.05 one-tailed (beauty>1.0 subset p=0.01).

Eight pre-screened research mediums each performed two phone readings for absent university student sitters in a novel triple-blind design: mediums knew only the deceased's first name, a blinded proxy sitter conducted the session, and sitters scored itemized transcripts without knowing which reading was intended for them. Each deceased parent was paired with a same-gender deceased peer. Intended readings received significantly higher global scores than controls (M = 3.56 vs. 1.94; t = 3.105, df = 15, p = 0.007, effect size = 0.5). Sitters chose the intended reading 81% of the time (13/16, p = 0.01). The design eliminates cold reading, fraud, and telepathy with the sitter as explanations, though it cannot distinguish survival of consciousness from super-psi.

Long and Holden identify eight major weaknesses: (1) 40% of NDErs denied any REM-intrusion experiences; (2) survey questions lacked validity — 'yes' answers may reflect post-NDE aftereffects rather than pre-existing diathesis; (3) the control group (medical personnel) likely underreported REM intrusion due to awareness of pathological implications (7% vs. 19-28% general population prevalence); (4) the control group was not matched for life-threatening event exposure; (5) NDEs occur when REM is suppressed (general anesthesia, barbiturate overdose, congenital blindness without REM); (6) NDE features (coherent narrative, profound peace, veridical perception) differ fundamentally from REM intrusion (brief, terrifying, bizarre hallucinations); (7) NDERF data show 73.5% of NDErs report the experience as 'more real than real' vs. dreams; (8) NDEs have a consistent deep structure across cultures, whereas REM dreams do not.

Prayer and Health: Review, Meta-Analysis, and Research Agenda

Minimal MA

An updated meta-analysis of 15 randomized studies on distant intercessory prayer found no discernible health effects. Using a random effects model, the overall effect was g = 0.082 (p = .26); excluding a fraudulent study (Cha & Wirth, 2001), the effect dropped to g = 0.003 (p = .97). No moderator variables — random assignment, prayer frequency, or intervention duration — significantly influenced outcomes. A narrative review of prayer frequency, prayer content, and prayer as a coping strategy found mixed but suggestive results via recognized psychological mechanisms. The authors recommend abandoning distant intercessory prayer research and focusing on naturally occurring prayer practices studied via longitudinal and experimental designs.

An automated, internet-based telepathy experiment tested whether receivers could identify which of four senders had been randomly selected to write them a short message in a one-minute trial. Across 198 completed 10-trial sessions by 195 receivers (1,980 total trials), the hit rate was 29.3% against a 25% chance baseline (p = 0.000006, 95% CI: 27-31%). In conditions with two real and two virtual senders, raw hit rates were markedly higher for real senders (41.9% vs 23.7%), but after correcting for response bias, this difference was not statistically significant (34.2% vs 30.1%). Family members yielded higher hit rates than non-family (31.4% vs 27.5%, p = 0.02). The unsupervised online format could not rule out cheating, limiting evidential weight.

Three fundamental problems with p value null-hypothesis significance testing (NHST) are reviewed with concrete examples. First, p values depend on data never observed, violating the conditionality principle. Second, p values depend on the researcher's subjective sampling intentions — identical data yield p = 0.146 under binomial but p = 0.033 under negative binomial sampling. Third, the 'p postulate' (equal p values = equal evidence) is false: Bayesian analysis shows that for data with p = .05, posterior probability of H₀ rises from ~0.69 at n = 400 to ~0.92 at n = 10,000. The Bayesian information criterion (BIC) is proposed as a practical alternative, approximating Bayesian hypothesis testing without requiring prior specification.

Synchronistic and psi phenomena are reinterpreted as entanglement correlations within Generalized Quantum Theory (GQT), a framework extending standard quantum mechanics to non-physical systems while preserving complementarity and entanglement. From the Non-Transmission (NT) axiom — that entanglement correlations cannot transmit information — three empirically observed features of psi research are derived: the decline effect (effect sizes diminish with replication), displacement (effects migrate to unmonitored variables), and elusiveness. PEAR PK replication data show effect sizes declining from E=0.024 (1981) to E=0.001 (2000), consistent with the predicted 1/√n decay. Correlation-matrix experiments yield significantly elevated psycho-physical correlations without any detectable signal, as the model predicts.

Long and Holden examine the REM intrusion hypothesis proposed by Nelson et al. (2006, 2007) in Neurology, which suggested that near-death experiences arise from disruptions in the arousal system. They identify multiple methodological weaknesses: survey questions may not have validly assessed REM intrusion; the comparison group (medical personnel) likely underreported sleep phenomena; temporal ambiguity means reported experiences could be NDE aftereffects rather than predispositions. NDEs occur under general anesthesia, in congenitally blind individuals, and without fight-or-flight activation — conditions incompatible with REM intrusion. The diathesis-stress model of NDEs remains 'entirely hypothetical,' and prospective hospital-based research designs are recommended.

A $2.4 million multicenter randomized clinical trial at six US hospitals examined whether intercessory prayer affects recovery from coronary artery bypass graft surgery. 1,802 patients were randomized to three groups: prayed-for but uncertain (n=604), not prayed-for and uncertain (n=597), or prayed-for and certain of receiving prayer (n=601). Three Christian prayer groups prayed for 14 days starting the night before surgery. Complications within 30 days occurred in 52% of uncertain prayed-for patients vs 51% of uncertain non-prayed-for patients (RR=1.02, 95% CI 0.92–1.15, p=.67), showing no effect of prayer. Patients certain of receiving prayer had significantly more complications at 59% (RR=1.14, 95% CI 1.02–1.28, p=.025). Intercessory prayer had no effect on complication-free recovery, and certainty of receiving prayer was associated with worse outcomes.

Using both fixed-effects and random-effects models, the analysis found a statistically significant but extremely small overall effect (REM: π = .500286, z = 4.08, p < .001, excluding three outlier studies). However, effect sizes were inversely related to sample size (small-study effect) and extremely heterogeneous (Q = 1508.56, p ≈ 0). A Monte Carlo simulation showed that a simple publication bias model could reproduce all three main findings, requiring approximately 1,500 unpublished null studies.

Book review of 'Irreducible Mind: Toward a Psychology for the 21st Century' by Kelly et al. (2007), an 800-page work attempting to understand consciousness and psi through F.W.H. Myers's concept of the subliminal mind. Kennedy endorses the book's approach of moving beyond narrow laboratory controversies toward a broader theoretical framework. The review examines the book's coverage of near-death experiences, mystical experiences, genius, automatism, and psychosomatic phenomena as evidence against materialistic models of consciousness. Kennedy identifies two areas needing further development: the role of biological evolution in consciousness/psi, and the implications of psi's capricious, evasive nature for understanding spiritual realms. The capricious nature of psi may reflect motivations fundamentally different from materialistic evolutionary drives, offering insight into profound aspects of consciousness.

overview

In a prospective study of 344 consecutive cardiac arrest survivors across ten Dutch hospitals, 62 (18%) reported near-death experiences, with 41 (12%) having core experiences. Neither physiological (cerebral anoxia), psychological (fear of death), nor pharmacological factors explained why only 18% had NDEs despite all being clinically dead. Longitudinal follow-up at 2 and 8 years revealed lasting transformational changes exclusively in NDE patients. Since EEG becomes isoelectric within 10–20 seconds of cardiac arrest, these experiences occurred during absence of measurable cortical activity. A nonlocal consciousness model is proposed: the brain functions as a receiver for consciousness fields in ‘phase-space,’ rather than producing consciousness.

Responding to critiques by Schub, Scargle, Ehm, and Bösch et al. of the Radin & Nelson (1989, 2003) RNG meta-analyses, this commentary challenges the 'influence-per-bit' assumption — that mind-matter interaction (MMI) operates uniformly on each random bit regardless of bit rate, sample size, or psychological conditions. With bit rates spanning six orders of magnitude across experiments, the authors argue this assumption is unjustified. Funnel-plot asymmetry is shown to reflect genuine heterogeneity rather than publication bias via simulated constant-z data. A researcher survey found ~1 unreported study per investigator, far fewer than the thousands needed to explain the cumulative results. Bösch et al.'s own random effects model yielded z = 4.08 for pre-planned studies.

Demonstrates that the four largest studies (4.54×10^11 bits) contain 320 times more data than all other studies combined and show z = -4.03, refuting the constant per-bit effect size model.

Mathematical modeling using 2x2 contingency tables proves that most published research findings are false. Positive predictive value (PPV) depends on statistical power (1-beta), pre-study odds (R), Type I error rate (alpha), bias (u), and number of competing teams (n). The core formula PPV = (1-beta)R/(R - betaR + alpha) shows a finding is more likely true than false only when power times pre-study odds exceeds 0.05. Six corollaries identify conditions reducing PPV: small studies, small effects, multiple testing, analytical flexibility, conflicts of interest, and competitive fields. Simulations show adequately powered RCTs achieve PPV = 85%, underpowered exploratory research achieves 12-23%, and discovery-oriented genomics achieves < 0.2%.

A preliminary meta-analysis of 60 supervised experiments (33,357 trials) examined whether people can consciously detect being stared at. Fixed-effects weighted mean effect size was e = 0.089 (z = 32.5, p = 10^-232), though significantly heterogeneous. A random-effects model yielded e = 0.114 (z = 10.9, p = 10^-28). The most compelling subset — 10 through-the-window studies without feedback, precluding implicit learning of sensory cues — produced a homogeneous distribution with e = 0.060 (z = 8.31, p = 4.8 x 10^-17). Trim-and-fill analysis adding 6 estimated studies still yielded p = 10^-184. File-drawer estimates of 1,417-7,729 missing studies make selective reporting implausible.

Experimental fMRI and EEG study investigating whether correlated neural signals can be detected between physically and sensorily isolated human subjects. A pre-selected pair (from 30 pairs in a prior EEG study) participated in fMRI sessions where the stimulated partner viewed a flickering checkerboard while the nonstimulated partner lay in a 1.5T MRI scanner 10 meters away, wearing sensory-isolating goggles in an EMF-shielded room. Subject DW showed significant BOLD activation in left visual cortex (BA 17/18/19) correlated with the partner's stimulus in both trials (p < 0.017, Bonferroni corrected). Subject CW showed significant activation in right BA 17/18 in the replication trial only. EEG confirmed correlated alpha-power changes in separate sessions (CW: chi-squared=455.4, p<.0001; DW: chi-squared=317.4, p<.005).

Testing for Telepathy in Connection with E-mails

Sheldrake, Rupert & Smart, Pamela • 2005

Low Rigor

This paper reports two series of experiments testing whether participants could correctly identify which of four potential e-mailers was about to send them an e-mail before receiving it. The design was modeled on prior telephone telepathy studies: one minute before each designated trial time, participants e-mailed the experimenter with their guess; the randomly selected e-mailer then sent their message at the exact designated time, copying the experimenter, providing time-stamped records establishing that guesses preceded messages. In Series 1 (unfilmed), 50 participants completed 552 trials; there were 235 hits (43%), far exceeding the 25% chance baseline (z = 9.49, p = 2 x 10^-19, Cohen d = 0.42; 95% CI 38%-47%). Forty-three of 50 participants scored above chance (expected 24 by chance; z = 5.54, p = 2 x 10^-8). An additional 48 partial-series participants achieved 34% hits (z = 2.94, p = 0.002). In Series 2 (videotaped), five high-scoring participants from Series 1 each completed 30 trials under continuous video surveillance with computer screens covered between trials; in 137 filmed trials there were 64 hits (47%; z = 5.77, p = 3 x 10^-8, d = 0.50). Four of five participants scored individually above chance. Familiar e-mailers produced higher raw hit rates than unfamiliar ones; among participants with two unfamiliar e-mailers and after correcting for response bias, the familiar-unfamiliar difference was statistically significant (z = 3.37, p = 0.0004). Some participants achieved high hit rates with senders thousands of miles away, including one participant whose senders were in Hong Kong (~6,000 miles). Results replicate Sheldrake and Smart's telephone telepathy findings and favor a telepathy interpretation over pure clairvoyance or precognition hypotheses, given the significant familiarity advantage.

Reviews evidence for the sense of being stared at (SOBA) across five historical and dozens of modern experiments. Direct-looking experiments (30,803 trials; 21 original studies plus 37 independent replications) yield 54.7% correct vs. 50% chance (sign test: 853 positive vs. 466 negative subjects; p=1x10-20). The NeMo Science Centre tested 18,793 subjects (32-41% vs. 20% chance threshold). A meta-analysis of 15 CCTV-based DMILS studies confirmed significant autonomic (GSR) responses to remote staring. Artifact controls (blindfolds, one-way mirrors, CCTV, automatic recording) failed to eliminate the effect. Skeptic investigators all obtained initial positive results; null results emerged when experimenters themselves served as lookers, suggesting an experimenter effect. The paper concludes most evidence supports SOBAs reality and outlines six directions for further research.

This theoretical companion paper to Part 1 examines what the empirically supported sense of being stared at (SOBA) implies for theories of visual perception. Sheldrake first surveys over two thousand years of debate between intromission theories (vision as passive inward movement of light) and extramission theories (vision as an active outward process), from Pythagorean and Empedoclean extramission through Democritean intromission, Platonic combined theories, Aristotelian medium-based accounts, Euclidean-mathematical extramission, and the Islamic synthesis of Alhazen, to Kepler's retinal image theory. He notes that extramission intuitions are remarkably persistent: surveys by Winer and colleagues found that 92% of older children and adults report feeling unseen stares, and most college students revert to combined intromission-extramission beliefs even after explicit instruction in orthodox intromission theory. Modern intromission-only theories (computational/representational models, virtual-reality-in-the-brain accounts) predict that SOBA should not exist, providing a falsifiable test that the evidence appears to fail. Alternative theories more compatible with SOBA include Gibson's ecological direct perception, the enactive/embodied approach of Varela and colleagues, and Velmans's reflexive model in which perceptual images are projected outward into phenomenal space. Sheldrake then presents his own morphic/perceptual field hypothesis: minds extend beyond brains through fields analogous to known physical fields; these perceptual fields link observer to observed, and field-field interaction provides a mechanism for SOBA. He further reviews four aspects of quantum physics potentially relevant to SOBA: the observer-observed interconnection in quantum measurement, Feynman's Wheeler-Feynman absorber theory (advanced waves moving backward in time from the eye), quantum entanglement and Clarke's proposal that consciousness arises from brain-world entanglement, and Zurek's quantum Darwinism in which preferred pointer states proliferate across observers. The paper concludes that while both the conventional internal-representation theory and the field/quantum alternatives remain incomplete, the conventional theory makes at least one clear testable prediction—SOBA should not exist—and the evidence undermines it.

Testing Alleged Mediumship: Methods and Results

O'Keeffe, Ciarán & Wiseman, Richard • 2005

Moderate

Five professional mediums certified by the Spiritualists Nationalist Union each gave one-hour readings for five male sitters under acoustically isolated, double-blind conditions preventing all sensory leakage. Sitters rated the accuracy of every statement (1-7 scale) from all 25 readings without knowing which was intended for them. Pratt-Birge permutation analyses found no significant results for any individual medium (p = .27 to .89) or combined (p = .63). In 24 of 25 cases, non-target sitters rated the readings higher than the intended sitter. Readings containing more general, diverse statements received higher absolute ratings consistent with the Barnum effect, while highly specific statements consistently received low ratings.

An anonymous mail survey of 3,247 NIH-funded US scientists (1,768 mid-career R01 grantees and 1,479 early-career postdoctoral trainees) asked respondents to self-report engagement in 16 specific questionable research practices over the past three years. While falsification and plagiarism were reported at under 2%, broader misbehaviours were strikingly common: 33% admitted to at least one of the ten most serious behaviours, including changing study design under funding pressure (15.5%), dropping data on gut feeling (15.3%), and inadequate record keeping (27.5%). Mid-career scientists reported significantly higher rates than early-career (38% vs 28%, P<0.001). The authors argue these are conservative estimates and call for attention to systemic features of the research environment that may foster misbehaviour.

Tested whether increasing bits per trial in REG experiments proportionally increases anomalous intention effects. Double-blind protocol with 2-million-bit 'high-density' and 200-bit 'low-density' trials interspersed randomly. 24 operators completed 1000-trial series in three intentional conditions. High-density trials produced significant reversed intentional effect (D = -0.0971, T = -3.90, p = 9.4×10⁻⁵) contrary to intention; low-density trials matched earlier REG results (D = 0.0189, ns). New operators showed larger effects than experienced, but both groups showed reversal. MegaMega companion experiment replicated the reversal. Effect size 2.77× larger per trial but 30× smaller per bit than standard REG200.

Mindless Statistics

Gigerenzer, Gerd • 2004

Non-Empirical

The 'null ritual' — NHST as routinely practiced in psychology — is an incoherent hybrid of Fisher's null hypothesis testing and Neyman-Pearson decision theory that neither statistician endorsed. Surveys show ~90% of psychology students, teachers, and professors hold false beliefs about p-values (Haller & Krauss, 2002). Meehl's conjecture that null hypotheses in large non-experimental samples are virtually always false is empirically supported: 46% of random directional predictions confirmed as significant across 81,000+ MMPI-2 responses (Waller, 2004). Statistical power in psychology has averaged ~50% for medium effects since 1962 without improvement. Advocates replacing the null ritual with a toolbox including Bayesian methods, effect sizes, and exploratory analysis.

Pharmaceutical clinical trials, with FDA-mandated power analyses, pre-specified primary outcomes, and independent protocol review, offer a rigorous model for psi research trapped in cycles of inconclusive meta-analysis. Examining published psi meta-analyses reveals that 70-80% of constituent studies are non-significant and z scores fail to increase with sample size — violating a fundamental assumption of statistical testing. A committee of parapsychologists, moderate skeptics, and a statistician is proposed to review pivotal study protocols prospectively. Kennedy challenges skeptics to specify adequate protocols in advance and proponents to demonstrate psi effects are reliable enough for prospective planning.

Prospective replication of Sheldrake & Smart (2003) telephone telepathy incorporating local sidereal time (LST) as an independent variable, following Spottiswoode's (1997) finding that anomalous cognition effect sizes peak around 13:30 LST. Six women completed 214 usable trials across 6 sessions (3 at peak LST, 3 at non-peak). Caller selection was randomized by dice at a separate location; an in-home experimenter monitored for signal leakage. Overall hit rate was 29.4% (p=0.05, one-tailed) above 25% chance; regular sessions: 32.7% (p<0.005). Peak-LST sessions yielded 34.6% vs. 25.2% non-peak (p=0.09). Emotional bond correlated with hit rate (r=0.41, p<0.05). Results tentatively support both telephone telepathy and the LST hypothesis, but LST was confounded with local time of day.

Using a counterbalanced crossover design, 26 participants (11 male, 15 female) experienced in HeartMath techniques viewed 45 randomly selected calm or emotional IAPS pictures while skin conductance and heart rate variability were measured. Heart rate showed significantly greater deceleration prior to future emotional stimuli compared to calm stimuli in the baseline condition (zpre = -3.19, p = 0.001), with curves diverging approximately 4.5 seconds before stimulus onset. Skin conductance showed no significant prestimulus differences, likely because all participants were experienced meditators. Females showed significant heart rate prestimulus response in both conditions; males only in baseline. The study provides the first evidence that the heart is involved in processing information about future emotional events.

Four double-blind experiments explored whether electrodermal activity (EDA) before randomly selected photographs differed based on upcoming emotional content. Across 133 participants and 4,569 trials at five sites using varied hardware and photo stimuli, pre-stimulus skin conductance was consistently higher before emotional than calm photos. The three replications combined yielded p = 0.001; all four produced a weighted mean effect size e = 0.064 +/- 0.015 (z = 4.04, p = 1.3 x 10^-5). A positive correlation between emotionality ratings and pre-stimulus EDA (r = 0.04, p = 0.008) supported a dose-response relationship. Analysis of anticipatory strategies found relaxation before emotional targets, ruling out the most common artifact explanation.

A separate analysis of 15 remote staring studies found d = 0.13 (p = .01, 95% CI [0.03, 0.23]).

This paper reports a filmed replication of telephone telepathy experiments, conducted with the Nolan Sisters—five sisters who were members of a popular 1980s British pop group—for a UK Channel Five television documentary. The experiment followed a previously validated four-caller randomized protocol: participant Colleen Nolan was taken to a private room at the Strand Palace Hotel approximately 1 km from her four sisters (Anne, Maureen, Linda, and Denise) in a Soho bar. An experimenter selected each caller at random using a casino-quality die, and the selected sister telephoned Colleen at a prearranged time. When the phone rang, Colleen had to name the caller before answering. Calls were made on landlines without caller ID. Both locations were filmed continuously on time-coded videotape, and the videotape of Colleen was evaluated blind by an independent observer, Pam Smart, who was absent during the trials. Twelve trials were conducted. Colleen correctly identified the caller in 6 of 12 trials (50%), compared to the 25% chance expectation, a result significant at p = 0.05 (both binomial and chi-squared tests). In sensitivity analyses excluding two trials in which Colleen answered before guessing, her score remained 5 out of 10 (50%). Notably, her only sceptical sister (Anne) yielded the lowest hit rate (0 of 1), while her self-described favourite sister (Linda) yielded the highest (2 of 2, 100%). The authors discuss and dismiss alternative explanations involving sensory leakage, cheating via concealed mobile phones, and unconscious use of timing cues.

Six neurological patients experiencing out-of-body experiences (OBE) or autoscopy (AS) were studied with phenomenological interviews, EEG, electrical cortical stimulation, neuropsychological testing, and neuroimaging. In 5 of 6 patients, brain damage or dysfunction localized to the temporo-parietal junction (TPJ). OBE was always preceded by supine position and accompanied by vestibular sensations (elevation, floating); in Patient 3, OBE was reliably induced by electrical stimulation at the right TPJ at 3.5 mA. The authors propose that OBE requires both a disintegration of proprioceptive-tactile-visual body information and a vestibular dysfunction disrupting the relationship between personal and extrapersonal space, both due to paroxysmal TPJ dysfunction.

Three of 10 peak amplitude comparisons showed significant differences between pre-observed and non-pre-observed conditions (overall exact binomial p=0.0115).

Percipients attempted to describe unknown geographical targets visited by agents, with 24 analytical scoring methods applied across binary, quaternary, and distributive descriptor formats. The composite database yielded z = 5.418 (p = 3×10⁻⁸), confirming anomalous information acquisition with no attenuation by distance or time. However, progressive refinement of scoring methods correlated with declining effect sizes, suggesting a complementarity between analytical precision and the subjective process generating the anomaly.

Six frontal patients (4 bilateral, 1 left, 1 right) and 6 normal controls attempted to influence output of portable REG from PEAR lab (200 samples/sec) translated into arrow movement on computer screen. Three intention conditions (right, left, baseline), each 10 blocks of 100 trials. Control runs without anyone in room. Primary finding: Left frontal patient (S5, 45M, tension pneumocephalus) showed significant effect for intention right vs control (t=-3.1691, p=0.0015), significant after Bonferroni correction, replicated in second study (p=0.0115). Effect lateralized contralateral to lesion. No significant effects for bilateral frontal, right frontal, pooled frontal, or normal subjects. REG output significantly different from theoretical mean of 100 (t=2.01, p=0.045), confirming effect not artifact. Pseudodata controls showed chance-level results.

After a century of psychical research, many investigators have concluded that psi may be capricious or actively evasive. Evidence includes negative reliability (significant direction reversals from pilot to confirmation), shifts from intended to unintended secondary effects, pervasive decline effects for subjects, experimenters, and entire research lines, and persistent failure of practical applications. Houtkooper found meta-analytic summary followed by 90% average reduction in effect size across seven series. Three hypotheses are evaluated: competing psi motivation from a polarized population, mechanistic constraints (Lucadou's pragmatic information model), and higher consciousness inducing mystery and wonder. Kennedy favors the last, arguing psi may be inherently unsustainable.

Variance permutation analysis gave p = 0.0009. A persistent trend continued through September 13 (permutation p ≈ 0.012). Five independent analysts confirmed anomalous structure. Physical explanations (electromagnetic disturbance, mobile phone usage) were ruled out. The overall GCP database of 98 formal predictions over three years showed composite p = 8.3 × 10⁻⁸.

Reporting results from the Global Consciousness Project (GCP), a worldwide network of approximately 50 quantum-based random number generators collecting continuous data since August 1998. Pre-specified examination periods corresponding to 109 major world events were analyzed for deviations from chance expectation. The aggregate chi-square attained p = 2.7 × 10⁻⁷ (z ≈ 5σ), with individual z-scores distributing normally around a shifted mean of 0.53 ± 0.1. Detailed analysis of September 11, 2001 data revealed the largest inter-node correlation in 400 days (p = 0.0002), device variance peak (p = 0.0009), and sustained network variance deviations. An independent news-intensity metric correlated with RNG deviations at r = 0.15 (p = 0.002). No conventional physical explanation was identified.

A critical commentary on two accompanying papers by Nelson and Radin analyzing Global Consciousness Project (GCP) random number generator data from September 11, 2001. Scargle, a NASA astrophysicist, identifies several methodological concerns: the XOR bit-flipping operation renders the GCP insensitive to direct coherent effects on bit frequencies; cumulative sums of chi-squared statistics create misleading visual structure resembling 1/f noise even in purely random data; and the GCP prediction registry lacks sufficiently specific hypotheses to eliminate post-hoc 'fiddle room.' When independent (non-overlapping) running means are applied instead, the data resemble white noise. Scargle concludes that none of the reported results are compelling and recommends Bayesian analysis, stricter prediction protocols, and blind parallel testing.

Survey of 100 mothers from the Active Birth Centre in North London examined claims of telepathic milk let-down when separated from their babies. 62% experienced let-down away from their infant; 16% of the total sample (26% of those experiencing let-down) reported it coincided with their baby needing them. Women who noticed coincidence breast-fed significantly longer (>6 months) than those who didn't (chi-squared=8.67, P<0.005). 31% reported other intuitive senses of baby's needs; 3 discovered their baby was in distress from accidents after feeling something was wrong. Results suggest emotional closeness may facilitate spontaneous telepathic connections, though self-report methodology cannot rule out selective memory or chance coincidence.

A review of research documenting widespread extramission beliefs among adults — the conviction that vision involves emissions from the eyes. Across multiple studies using computer animations, drawings, and verbal forced-choice items, 41–67% of college students affirmed extramission representations; drawing tasks yielded rates as high as 86%. At least 70% of believers judged emissions as functionally necessary for seeing. Standard educational interventions (textbook readings, introductory psychology coursework) failed to reduce the misconception. Refutational teaching produced short-term gains (100% correct on immediate posttest) that vanished within 3–5 months. The authors attribute the belief’s persistence to primitive phenomenological experiences of outer-directed vision that syncretically fuse with lay theories of the visual process.

Proposes a minimal axiomatic generalization of quantum theory — "Weak Quantum Theory" (WQT) — in which observables are mappings on states forming a monoid rather than a C*-algebra. Six axioms preserve the key quantum features of complementarity (non-commuting observables) and entanglement (holistic correlations in composite systems) while discarding Planck's constant, Hilbert space, tensor products, and probability interpretation. Ordinary quantum theory is recoverable by progressively strengthening the axioms. Two applications are sketched: complementary dynamical descriptions in chaotic systems, and countertransference in psychotherapy as entangled mental states. Provides formal underpinning for applying entanglement concepts to mind-matter and psychophysical phenomena without claiming that quantum physics itself directly governs such processes.

Stimulating illusory own-body perceptions

Blanke, Olaf et al. • 2002

Low Rigor

Focal electrical stimulation of the right angular gyrus in a 43-year-old epilepsy patient undergoing presurgical evaluation reproducibly induced out-of-body experiences. At lower currents (2.0–3.0 mA), vestibular sensations of sinking or falling were reported; at 3.5 mA, the patient described seeing herself lying in bed from above, floating near the ceiling. The same site also induced complex somatosensory illusions: legs appearing shorter, arms seeming to move toward the face. OBE visual content was restricted to body parts also subject to somatosensory distortion, and the epileptic focus was >5 cm away. These findings suggest OBEs result from a failure to integrate somatosensory and vestibular information at the temporo-parietal junction.

Meta-analysis of 40 ganzfeld studies published after Bem and Honorton (1994), including 30 from Milton and Wiseman (1999) plus 10 new studies. The 10 new studies yield hit rate of 36.7% (Z=3.97, p=3.5×10⁻⁵); all 40 combined yield 30.1% (Z=2.59, p=.0048). Three independent raters rated each study's adherence to standard ganzfeld protocol. Standardness ratings significantly correlated with effect size (r=.31, p=.024). Standard replications (n=29) achieved 31.2% hit rate (ES=.096, Z=3.49, p=.0002), within confidence intervals of earlier studies. Non-standard replications (n=9) achieved only 24.0% (ES=−.10, Z=−1.30, ns).

The Anticipation of Telephone Calls: A Survey in California

Brown, David Jay & Sheldrake, Rupert • 2001

Low Rigor

A telephone survey of 200 randomly selected people in Santa Cruz County, California investigated the frequency and nature of anticipations of telephone calls. Results showed 78% had telephoned someone who said they were just thinking about calling them, 47% had known who was calling without any possible cue before the caller spoke, and 68% had thought about someone not seen for a while who then telephoned that same day. Women reported higher rates than men across all question types, though differences were not statistically significant. The proportion reporting other telepathic experiences was 45%, and those with other telepathic experiences were significantly more likely to report telephone-related intuition (p = 5 × 10⁻⁸). Unlike previous English surveys, no significant difference was found between pet owners and non-pet owners. The 20% participation rate may indicate self-selection bias. Results are compared with two English surveys and suggestions are made for empirical investigation through log books and controlled experiments where callers are randomly selected from a nominated pool.

Eleven hypotheses for why psi phenomena are weak, unreliable, and rare are reviewed: methodological artifacts, rarity of ability, precarious psychological conditions, unnoticed psi, goal-oriented experimenter effects, fear of psi, evolutionary inhibition, ecological interconnectedness, spiritual growth, multiple-observer influence, and nonphysical beings. Meta-analyses consistently show z scores unrelated to sample size, contradicting standard statistical assumptions, and replication rates declined across paradigms despite decades of research. An integrative model proposes a bimodal distribution of anomalous experiences, with psi practitioners (~1%) forming a subset who reliably guide psi by intention and psi-conducive experimenters shaping outcomes via goal-oriented influence.

A prospective, randomized pilot study (MANTRA I) at Duke University examined four noetic therapies — stress relaxation, imagery, touch therapy, and off-site intercessory prayer — as adjuncts to percutaneous coronary intervention in 150 patients with unstable coronary syndromes. Patients were randomized across five arms (four noetic plus standard therapy). Acceptance was excellent (88% consent, 98% treatment completion). No outcomes reached statistical significance, but there was a 25-30% absolute reduction in adverse periprocedural outcomes with noetic therapy (ACE 20.4% vs 25.9%). Off-site prayer showed the lowest complication rates. However, all 6-month mortality occurred in noetic therapy groups (9.2% vs 0%, P = .12), raising safety considerations for future trials.

Double-blind RCT testing whether retroactive intercessory prayer affects outcomes in 3,393 patients with bloodstream infection at Rabin Medical Center, Israel (1990-1996). In July 2000, patients were randomized and a single person said a short prayer for the intervention group's recovery — 4 to 10 years after the infections. Mortality was 28.1% (475/1691) in the intervention group versus 30.2% (514/1702) in controls (P = 0.4, not significant). Length of hospital stay was significantly shorter in the intervention group (median 7 vs 8 days, P = 0.01), as was duration of fever (P = 0.04). Published in the BMJ Christmas issue, the study is both methodologically rigorous and conceptually provocative, testing retrocausal prayer with a large, well-balanced sample.

Prospective study of 344 consecutive cardiac arrest patients resuscitated across ten Dutch hospitals (1988-1992). Of these, 62 (18%) reported near-death experiences, with 41 (12%) describing core experiences and 23 (7%) deep experiences on the weighted core experience index. NDE occurrence was unrelated to duration of cardiac arrest or unconsciousness, medication, or fear of death — findings that challenge purely physiological explanations such as cerebral anoxia. Patients under age 60 reported more NDEs (p=0.012) and women had deeper experiences (p=0.011). Longitudinal follow-up at 2 and 8 years showed NDE patients underwent sustained transformational changes including decreased fear of death and increased spirituality compared to matched controls.

The Global Consciousness Project maintains a network of ~50 hardware random event generators (REGs) at host sites worldwide, producing continuous random data streams. Data are analyzed for non-random patterns correlated with major global events. Formal predictions registered in advance test whether widespread human attention and emotion correlate with departures from randomness. Composite analysis of 105+ predictions over 4 years shows cumulative deviation with odds against chance ~1,000,000:1. Notable effects include September 11 attacks (p<0.001, with apparent precognitive response), New Year's celebrations (p≈0.003), NATO bombing of Kosovo (p=0.045), and Princess Diana's funeral (100:1 odds). Results interpreted as evidence for a global consciousness field or observer effects, though alternative explanations remain.

Re-analysis and extension of Milton and Wiseman's (1999) negative ganzfeld meta-analysis, which had found ES = 0.013 (Z = 0.70, p = .24) across 30 studies and questioned whether the ganzfeld paradigm produces replicable ESP. By assembling four databases spanning 1970–1997 — Honorton's (1985) 28 studies, 11 overlooked 1982–1986 studies, Bem and Honorton's (1994) 10 autoganzfeld studies, and Milton and Wiseman's 30 studies — a unified 79-study database yielded ES = 0.138, Stouffer Z = 5.66, p = 7.78 × 10⁻⁹, with an overall hit rate of 31% vs. 25% MCE. Bidirectional psi effects were significant in every database. The authors conclude that the ganzfeld remains a replicable technique for demonstrating anomalous communication.

A cross-sectional survey compared posttraumatic stress symptoms in 148 near-death experiencers and 46 individuals who came close to death without NDEs, using the Impact of Event Scale (IES). NDErs scored 9.0 points higher on the overall IES (95% CI = 3.4–13.7), but the elevation was confined to intrusive re-experiencing symptoms; avoidance symptoms did not differ between groups. Multiple regression confirmed NDEs as a significant predictor of intrusion (B = 7.59, p < 0.001) but not avoidance, after controlling for demographics and event characteristics. NDErs' scores fell 1.2 SD below a clinical PTSD criterion sample, suggesting a nonspecific stress response rather than clinical PTSD.

Analyzing 553 NDE cases from the University of Virginia collection, 74 cases involving reports of meeting recognized deceased persons were compared against 200 cases without such reports (for which medical records were available). People closer to death were significantly more likely to report seeing deceased persons (76% vs 51%, χ² = 6.69, p < .01). Deceased-person cases were associated with sudden-onset conditions (accidents, cardiac arrests) rather than gradual ones (surgery, childbirth; χ² = 13.02, p < .025). No age difference existed between groups, and 32% of deceased persons seen were emotionally neutral or never met. These patterns weaken the expectation/hallucination hypothesis and warrant more serious consideration of the survival hypothesis.

Three-laboratory consortium (Princeton PEAR, Freiburg FAMMI, Giessen GARP) attempted to replicate PEAR’s 12-year anomalous REG database. Using identical PortREG equipment and tripolar (HI/LO/BL intention) protocol, 227 operators generated 750 experimental sessions totaling ~2.25 million 200-bit trials. The primary criterion — matching PEAR’s prior HI-LO mean shift of delta=0.0208, Z=3.809 — failed by an order of magnitude (combined Z=0.596, delta=0.0034). Yet structural anomalies persisted across all sites: near-universal depression of trial-level standard deviations, irregular series-position patterns, and secondary-parameter dependencies at composite p=0.001–0.002. Authors frame this as an ‘empirical paradox’: the ordered mean-shift effect gave way to a polyglot pattern of structural distortions, suggesting the phenomena are real but inadequately modeled.

Notably, significantly more people anticipated calls than reported psychic experiences (51% vs 38%, p < 0.0004). Bury survey (N=200, June-July 1997) found 65% had telephoned someone who said they were just thinking about telephoning them (71% women vs 53% men, p < 0.02); 49% knew who was calling without cues; 45% thought about someone not seen for a while who then called same day. Pet owners showed non-significantly higher positive responses in both surveys. Response rates were 70-75%. Telephone anticipation may represent one of the commonest forms of psi experience.

In 12 formal experiments with randomly selected return times (signaled by pager from 300+ km away, unknown to anyone at home), Jaytee spent 4% of time at the window during the main absence versus 55% during the first 10 minutes of the return journey (repeated-measures ANOVA F(2,22)=20.46, p<.0001). Similar patterns appeared in 30 ordinary homecomings (11% vs 65%, p<.0001), when Jaytee was alone (p<.01), and in Wiseman et al.'s independent experiments (4% vs 78%, p=.02). Control evenings with no return showed no increasing window visits. The authors conclude the anticipation may depend on a telepathic influence from the owner.

In 9 of 10 trials, anticipatory behavior occurred; in 3 trials with randomly-timed returns via pager, the dog responded in 2. Results cannot be explained by routine, time-of-day patterns, or cues from people at home who were unaware of return times.

Consecutive coronary care unit admissions (N=990) at Mid America Heart Institute were randomized to receive daily remote intercessory prayer from teams of 5 Christian volunteers for 28 days, or usual care alone, under fully double-blind conditions with an IRB waiver of informed consent. Using a newly developed weighted MAHI-CCU composite score of 34 adverse events and procedures, the prayer group scored 11% lower than usual care (6.35 vs 7.13, P=.04). The unweighted event count also favored prayer (2.7 vs 3.0, P=.04). However, the effect did not replicate using Byrd's original categorical hospital course score (P=.29), and no individual outcome component reached significance.

Two-laboratory experimental study testing whether human intentionality can reduce the fringe contrast of a Young's double-slit interference pattern, framed as a test of anomalous quantum wavefunction collapse.

Princeton PEAR lab operators (20 series, goal-directed) achieved a marginal effect (Z = 1.654, p ≈ 0.049), consistent in scale with other PEAR REG experiments.

Commissioned alongside Jessica Utts to evaluate the U.S. government-funded Stargate remote viewing program at SRI and SAIC (1973–1994), Hyman focuses on the ten most recent SAIC experiments. He concedes these experiments are methodologically superior to earlier SRI work and that statistical effects are too large to dismiss as chance flukes. However, he argues Utts’ conclusion that psychic functioning has been proven is premature: the experiments were conducted in secrecy precluding peer review, relied on the same viewers, targets, and a single judge (the principal investigator) across all studies, and have not been independently replicated. He identifies key inconsistencies between ganzfeld and remote viewing findings and argues that without a positive theory of anomalous cognition, statistical departures from chance alone cannot establish its existence.

FieldREG Anomalies in Group Situations

Nelson, Roger D et al. • 1996

Low Rigor

Portable random event generators with software to record and index continuous sequences of binary data in field situations are found to produce anomalous outputs when deployed in various group environments. FieldREG systems operated under formal protocols in ten separate venues (professional meetings, religious rituals, group gatherings), all subdividing naturally into temporal segments. The most extreme data segments from each of the ten applications, after appropriate correction for multiple sampling, compound to a collective probability against chance expectation of 2×10⁻⁵. High degrees of attention, intellectual cohesiveness, shared emotion, or other coherent qualities of the groups tend to correlate with the statistically unusual deviations. Effect sizes per bit (0.0003) and per hour (average 0.3) are similar to laboratory REG experiments.

Commissioned by the CIA at Congress's request, this systematic statistical review examines two decades of government-sponsored remote viewing research at SRI International (1973-1989) and SAIC (1990-1995). Across 770 SRI sessions (effect size 0.209) and 445 SAIC sessions (effect size 0.230), anomalous cognition exceeded chance with remarkable consistency. Expert viewers replicated effect sizes of ~0.35 across institutions and years. Independent ganzfeld replications at four laboratories yielded consistent 32-37% hit rates against 25% chance. Utts concludes that psychic functioning is well established by standard scientific criteria and recommends redirecting resources from proof-oriented experiments toward understanding the underlying mechanism.

Experimental parapsychology faces a fundamental challenge if psi is goal-oriented and operates within a hierarchy of goals ranging from individual trials to entire research programs. Drawing on Schmidt (1974), where single-event PK trials (55.93%, z=5.55) and 100-event majority-vote trials (53.16%, z=2.89) produced approximately equal scoring rates despite communication theory predicting >90% for majority votes, the paper demonstrates that psi bypasses redundant opportunities to achieve goals directly. If psi operates efficiently at higher levels of the goal hierarchy, standard experimental methods may be unable to identify optimum conditions for psi.

Introduces Decision Augmentation Theory (DAT), proposing that statistical anomalies in micro-psychokinesis experiments arise not from a mental force perturbing physical systems but from anomalous cognition (precognition) biasing human decisions toward favorable outcomes within an unperturbed world. Mathematical expressions are derived for normal and binomial distributions, yielding a key testable prediction: under DAT, the expected z² is independent of n (items per trial), whereas force-like models predict z² increases linearly with n. Statistical power curves show that ~1,368 runs at n=10⁴ suffice to separate models at 95% confidence for typical RNG effect sizes. The theory implies all anomalous mental phenomena may reduce to a single mechanism—information transfer from future to past.

Commissioned by the CIA, this report evaluates the government-sponsored Star Gate remote viewing program through two components: a blue-ribbon research review by statistician Jessica Utts and psychologist Ray Hyman, and an operational assessment based on end-user interviews and feedback data. Both reviewers agreed that laboratory experiments demonstrated a statistically significant effect (effect size ~0.385 across 196 SRI sessions with expert viewers), but disagreed on interpretation — Utts concluded psychic functioning was well-established, while Hyman argued methodological issues (particularly single-judge evaluation by the principal investigator) prevented unambiguous attribution to paranormal phenomena. The AIR team concluded that adequate evidence for remote viewing had not been provided and that the phenomenon never produced actionable intelligence, recommending program discontinuation.

Reviews competing meta-analyses of 28 ganzfeld psi studies (Hyman 1985 vs. Honorton 1985) and presents 11 new autoganzfeld studies from Honorton's Psychophysical Research Laboratories. The original 28-study database yielded a composite z = 6.60 (p = 2.1 × 10⁻¹¹) with a 35% hit rate against 25% chance (effect size h = .28, 95% CI [.11, .45]). The 11 autoganzfeld studies (240 receivers, 329 sessions) achieved 32% hits (z = 2.89, p = .002, π = .59). Dynamic video targets outperformed static targets (37% vs. 27%, p < .04). Juilliard performing arts students hit at 50% (p = .014). Concludes the ganzfeld effect is replicable and large enough to warrant mainstream attention.

Einstein-Podolsky-Rosen (EPR) correlations between human brains were investigated to test whether the brain has a macroscopic quantum component. Seven pairs of subjects meditated together for 20 minutes, then were separated into soundproof Faraday chambers 14.5 m apart. Subject A received 100 light flashes while both subjects' EEGs were recorded from occipital derivations with high-pass filtering above 12.7 Hz. In ~25% of pairs reporting successful 'direct communication,' Subject B showed 'transferred potentials' morphologically matching Subject A's evoked potentials (r = 0.70-0.93, p < 0.005). All control conditions showed no transferred potentials. Interpreted as evidence for macroscopic quantum nonlocality between correlated brains.

Reanalysis of 11 autoganzfeld experiments (N = 330 sessions) from Bem and Honorton (1994) reveals inconsistencies challenging the claim of a replicable psi effect. Hit rate correlates strongly with target occurrence frequency (Spearman r = .83, p = .013), and a significant interaction with experimenter prompting shows hit rates jumping from .140 (first occurrences) to .445 (later occurrences; chi-squared = 14.702, p = .0001). The overall effect is a composite of different rates for dynamic (.372) versus static (.271) targets, undermining claimed consistency with the original ganzfeld database. Hyman concludes that inadequate randomization testing and target-frequency patterns cast doubt on whether results reflect psi or artifact.

Reviews 15 experiments testing whether mental intention of one person can influence the electrodermal activity (skin resistance responses, SRR) of another person in a separate, isolated room. Conducted at the Mind Science Foundation, the protocol seated subjects in a shielded room while an influencer 20 m away attempted to mentally calm or activate them during randomly scheduled 30-second periods (10 influence, 10 control per session), with subjects blind to the timing. Data from 323 sessions with 271 subjects and 62 influencers were analyzed using Stouffer's z. Thirteen of 15 experiments yielded results in the expected direction; 6 of 15 (40%) were independently significant at p < .05, versus 5% expected by chance; combined Stouffer z = 4.08, p = .000023; mean effect size d = 0.29. Subjects and influencers were unselected community volunteers, suggesting the effect may be broadly distributed. Traces historical precedents in Soviet psychophysiology (Vasiliev, Bekhterev) and calls for independent laboratory replications.

Survival or Super-psi?

Braude, Stephen E • 1992

Non-Empirical

Argues that even the most sophisticated discussions of survival evidence underestimate the conceptual difficulties posed by the rival 'super-psi' hypothesis. Two major weaknesses in survival arguments are identified: superficial treatment of subject psychodynamics when analyzing anomalous propositional knowledge, and naive conceptions of human abilities when analyzing anomalous skills. Cases examined include Eisenbud's depth-psychological analysis of the Cagliostro persona, Stevenson's Sharada/Uttara xenoglossy case, the Patience Worth literary productions, and evidence from child prodigies and dissociation. Published alongside Stevenson's formal reply and Braude's counter-reply in the same issue of JSE (Vol. 6, No. 2, pp. 127-155).

Three experiments investigated whether stimulus-evoked brain potentials could be 'transferred' between people isolated in separate electromagnetically shielded Faraday chambers. Pairs first established 'direct communication' — nonverbal meditative co-presence in darkness — then separated into two soundproof chambers 270 cm apart. One subject received randomized light flashes while the other's EEG was time-locked to stimulus onset. In Experiment 1 (5 pairs), transferred potentials correlated r = 0.629–0.966 with evoked potentials at 150–276 ms latency. In Experiment 2 (14 subjects), approximately 57% showed transferred potentials (r = 0.606–0.980). No transferred potentials appeared in non-communicating control pairs.

Surveyed 27 long-term Vipassana meditators (mean 4.27 years experience; 17 men, 10 women) at an intensive retreat in Barre, Massachusetts, using retrospective and prospective questionnaires at one month and six months post-retreat. Of the 27 subjects, 62.9% reported at least one adverse effect across the three time periods, and 7.4% suffered profound adverse effects leading them to stop meditating. Adverse effects were primarily intrapersonal (76.4%), including increased negativity, emotional pain, anxiety, and disorientation. Despite this, subjects reported significantly more positive than negative effects (p=.002 at time one). Frequency of adverse effects was not reduced by longer practice — the longest-term group (105 months average) reported the highest rate (75%).

Influencers attempted to mentally affect remote biological targets — including human electrodermal activity, blood pressure, muscular tremor, fish orientation, gerbil locomotion, and red blood cell hemolysis — while isolated in separate rooms with randomized influence/non-influence epochs. Twenty-one of 37 experiments reached individual significance (57% vs. 5% by chance). The overall Stouffer z = 7.72 (p = 2.58 × 10⁻¹⁴) with mean effect size r = .33 across all systems. Additional studies showed electrodermal correlates of remote attention (staring detection). Results are interpreted as laboratory analogs of mental healing.

Biological Utilisation of Quantum NonLocality

Josephson, Brian D & Pallikari-Viras, Fotini • 1991

Non-Empirical

Nobel laureate Brian Josephson and Fotini Pallikari-Viras argue that Bell's theorem demonstrates the existence of nonlocal connections between spatially separated objects, but that standard quantum mechanics predicts these connections vanish under statistical averaging. Drawing on Bohm's causal interpretation, they propose that this vanishing is an artifact of the specific probability distributions relevant to quantum measurement, and that biosystems — through evolutionary adaptation and developmental learning — may access qualitatively different, goal-focused distributions enabling practical use of nonlocality for telepathy and psychokinesis. The theory is entirely qualitative, offering no quantitative predictions.

Effects of Consciousness on the Fall of Dice: A Meta-Analysis

Meta-analysis of 148 dice-throwing PK experiments (1935–1987) by 52 investigators, involving 2,569 subjects and over 2.59 million dice tosses. The full database showed an effect 19 SE from chance (ē = 0.01220), but a physical dice bias artifact was identified: higher die faces show inflated hit rates due to mass asymmetry. A subset of 59 homogeneous studies using balanced protocols (controlling for dice bias) yielded a smaller but still significant effect (ē = 0.00315, z = 3.188, p = .001), with no significant relationship between effect size and methodological quality. The pre-1975 database showed evidence of selective reporting bias. Concludes with "weak cumulative evidence" for a genuine mental intention effect on dice.

Fuzzy set technology is applied to automate analysis of remote-viewing data from SRI International's government-sponsored program. The technique encodes target and response material as fuzzy subsets of a 131-element Universal Set of Elements, then computes accuracy (percent of target correctly described), reliability (percent of response that was correct), and a figure of merit (FM = accuracy × reliability). Tested on 6 RV trials from a photomultiplier experiment against ground truth from 37 independent analysts, the FM values showed good agreement with subjective assessments. Combined result: z = 1.633, p < .05, r = 0.67. Cluster analysis of 200 targets yielded 19 visually distinct groups, providing a quantitative definition of target orthogonality for constructing balanced decoy sets.

A gas discharge cell with dielectric-coated electrodes and ~1 mm gap was operated at voltages several percent below breakdown to measure the effect of focused human attention on electron microavalanche size. Approximately 50 subjects were tested over a three-year period (1977-1979) in several thousand tests at Stanford University. Nearly all subjects produced enhanced counting rates when focusing attention on the device, with WBH/WOH ratios averaging ~2×10⁴:1. Faraday cage shielding, metal foils, and magnetic shielding did not block the effect. Mental focus alone (without hand proximity) produced enhancement, while hand proximity with attention diverted to arithmetic did not, indicating a cognitive rather than physical mechanism. No conventional energy source (IR, UV, gamma, electric, magnetic) could reproduce the effect.

Applying Bayesian hypothesis testing to Jahn, Dunne & Nelson's (1987) PEAR random event generator dataset of 104.49 million trials reveals that the Jeffreys-Lindley paradox undermines the strong classical p-values reported. Under a uniform prior on the alternative hypothesis, the Bayes factor B = 12, actually increasing confidence in the null. For nearly all reasonable prior distributions on effect size, B exceeds 1 (favoring no anomaly). Even the most favorable prior yields B approximately 30 times larger than the classical p-value, showing the frequentist test overestimates significance by at least a factor of 20. Jefferys concludes these data are insufficient to shift the opinions of observers with even moderate priors, and advocates Bayesian methods as more appropriate for parapsychology.

Pairs of subjects (13 pairs plus 4 triads) were seated in a Faraday cage, separated by 50cm with eyes closed and no sensory contact. EEG was recorded from frontal-occipital derivations (3-45 Hz) and interhemispheric correlations computed every 256ms using Pearson's r. An A-B-A design compared control isolation periods to communication periods where subjects intentionally connected. During direct communication, individual interhemispheric correlation patterns became highly similar (r≈0.80 vs. r≈0 in control), and intersubject EEG concordance increased significantly. Pattern convergence was pair-specific and not attributable to habituation or fatigue.

David Marks examines the SRI remote viewing (RV) experiments by Targ and Puthoff with subjects Pat Price and Hella Hammid. He documents data suppression—Targ and Puthoff refused to release raw transcripts—then demonstrates that the Hammid transcripts contain 24 identifiable sensory cues (dates, experimenter names, temporal references, cross-session comments) enabling correct ordering without ESP. Independent judges in New Zealand (12,000 km away) used only these cues to achieve p=.001 in blind transcript matching, equaling the original SRI judge's performance. A systematic review of replication attempts finds a clear pattern: all well-controlled RV studies fail (Allen 1976; Karnes 1979, 1980), while positive results appear only in flawed designs. Marks concludes remote viewing is a cognitive illusion produced entirely by methodological artifact.

Key discovery: the ancient seawall extending ~65 meters further seaward than previously known. Stone 'beads' at the Pharos site, predicted by viewer R3 before diving, were confirmed underwater.

Landmark statistical critique of ESP research by Harvard statistician Persi Diaconis, published in Science (Vol. 201, No. 4351, pp. 131–136). Analyzes four classes of methodological problems that generate spurious positive results: (1) optional stopping — analyzing data repeatedly and halting collection when significance is reached, without a pre-specified stopping rule; (2) multiple testing — examining many subjects, conditions, and measures then reporting only significant outcomes; (3) inadequate randomization — pseudo-random target sequences in Rhine-era experiments had detectable statistical regularities that subjects' guessing strategies exploited; and (4) sensory leakage — insufficient physical isolation in card-guessing paradigms provided olfactory, visual, and auditory cues. Concludes that better-controlled experiments consistently yield weaker or null results, and that statistical analysis alone cannot validate ESP claims without rigorous experimental design.

Arguing that theories in soft psychology (clinical, social, personality) neither cumulate nor get clearly refuted but merely fade away, Meehl identifies 20 intrinsic difficulties of the subject matter and then turns to an extrinsic one: the near-universal reliance on null hypothesis significance testing. Drawing on Popper's falsificationism and Bayesian reasoning, he shows that since the null hypothesis is quasi-always false, refuting it depends on statistical power, not theoretical verisimilitude, making significance tests a feeble method of theory corroboration. As an alternative, he demonstrates 'consistency tests' within his MAXCOV-HITMAX taxometric framework, achieving 94% accuracy with zero false negatives across 600 Monte Carlo samples.

Fifty-one double-blind remote viewing experiments at Stanford Research Institute tested whether individuals could perceive and describe remote geographical or technical targets. Six subjects (experienced and learners) plus visiting scientists generated tape-recorded descriptions and drawings of randomly selected target locations while closeted with a blind experimenter. Blind rank-order judging yielded highly significant results for experienced subject Price (p = 2.9 x 10⁻⁵) and learner Hammid (p = 1.8 x 10⁻⁶). Faraday cage shielding did not degrade performance. Four precognitive trials, where descriptions were completed before target selection, were matched without error by three independent judges. The authors conclude that remote viewing is a latent, widely distributed perceptual ability predominantly involving non-analytic (shape, form, color) information consistent with right-hemisphere processing.

Information transmission under conditions of sensory shielding

Targ, Russell & Puthoff, Harold E • 1974

Non-Empirical

Researchers at Stanford Research Institute conducted experiments investigating anomalous information transfer under sensory-shielded conditions. Three main experiment series were reported: (1) drawing reproduction by Uri Geller in an electrically shielded room, where two independent judges achieved perfect target-response matching; (2) remote viewing by Pat Price, who described distant geographical targets visited by an outbound experimenter, with blind judge matching yielding P = 3 × 10⁻⁴ across nine trials (24/45 correct matches vs. 5 expected); and (3) EEG experiments showing alpha-blocking in one subject correlated with remote strobe stimulation. The authors concluded that a perceptual channel exists for information transfer about remote locations through an unidentified modality.

Low Rigor

Alpha rhythms were elicited in one of a pair of identical twins as a result of evoking these rhythms solely in the other twin seated in a separate room 6 meters away. Fifteen monozygotic twin pairs were tested using simultaneous EEG with subcutaneous occipital electrodes; one twin closed their eyes to produce alpha rhythm while the other was monitored. Extrasensory induction was found in 2 of 15 pairs — both educated, calm males aged 23 and 27. No induction occurred between unrelated control subjects. The authors concluded that extrasensory induction of brain waves exists between some identical twins when completely separated.

Extra-Sensory Perception

Rhine, J. B • 1934

Non-Empirical

The foundational monograph that launched modern experimental parapsychology. Rhine describes systematic card-guessing experiments at Duke University (1930-1933) using Zener cards (five symbols) and playing cards, reporting statistically significant evidence for extra-sensory perception across 64,000+ trials. Major subjects include A.J. Linzmayer, Charles E. Stuart, and Hubert E. Pearce Jr., with X values (critical ratios) reaching 75.3. Introduces the term 'ESP' and establishes the experimental paradigm with telepathy and clairvoyance conditions. Published by Boston Society for Psychic Research with foreword by William McDougall.

Phantasms of the Living

Gurney, Edmund et al. • 1886

Non-Empirical

Foundational two-volume compendium from the Society for Psychical Research combining controlled thought-transference experiments with a systematic collection of 702 spontaneous cases of telepathic impressions, crisis apparitions, and death-coincident hallucinations. Experimental evidence includes 17,653 card-guessing trials yielding 4,760 successes versus 4,413 expected by chance (p < 0.00000002), plus diagram-reproduction and sensation-transference experiments by Barrett, Guthrie, Lodge, and Richet. A probability argument demonstrates that death-coincident hallucinations occur far more frequently than chance predicts. Concludes that experimental and spontaneous phenomena jointly support the reality of telepathy.
