Parapsychological Research: A Tutorial Review and Critical Appraisal
⚡ Contested ↗Plain English Summary
Psychologist Ray Hyman wrote this landmark skeptical overview for engineers at IEEE, and it became a cornerstone of the case against psi (psychic phenomena). He surveys 130 years of evidence — from Victorian seances through Rhine's card-guessing labs to modern ganzfeld (sensory-deprivation telepathy tests) and remote viewing. His key idea is the "False Dichotomy": critics feel trapped between accepting psychic powers or crying fraud, when really subtle methodological mistakes often explain things. His most damaging argument? Parapsychology's evidence never builds on itself — each generation's best proof gets debunked, then a shiny new method appears and the cycle restarts. He notes that 85% of top ESP studies had serious flaws. A copy even turned up in declassified CIA Stargate files.
Research Notes
Landmark skeptical review for IEEE, written concurrently with the Hyman-Honorton Joint Communiqué on ganzfeld. Introduces the 'False Dichotomy' framework and the non-cumulativeness argument that remain central to the skeptical position. Copy declassified from CIA (Stargate) archives.
Invited review surveying 130 years of parapsychological research for a mainstream engineering audience. Examines historically prominent evidence from 1850s spiritualism (Crookes/Home, the Creery sisters) through Rhine's card-guessing program, the Soal-Shackleton experiments (later shown fraudulent by Markwick in 1978), and contemporary ganzfeld, RNG, and remote viewing paradigms. Introduces the 'False Dichotomy' concept: critics feel forced to accept psi or accuse fraud, missing subtler explanations. Argues that parapsychological evidence is fundamentally non-cumulative—each generation's best cases are discredited and replaced by new paradigms repeating the same patterns. Notes Akers' finding that 85% of 54 selected ESP experiments had serious methodological flaws.
