Plain English Summary

Does some part of us survive death? That's one of the biggest questions humans have ever asked, and this paper by the IONS research team takes a remarkably systematic crack at evaluating the evidence. Borrowing a grading framework from medical research (think A through F, like a report card), they scored nine different categories of survival evidence. The top marks went to mental and physical mediumship, earning a B+. Reincarnation cases and the out-of-body aspects of near-death experiences scored a respectable B-minus. Electronic voice phenomena and deathbed visions landed at C+, while apparitions and after-death communications got a plain C. Notably, nothing earned an A — largely because there's a stubborn problem researchers can't yet crack: how do you tell whether a medium is genuinely communicating with the dead versus using some other form of psychic ability to pull information from living minds? The team also proposed ten new experiments and surveyed 422 academics about what evidence would actually change their minds. The winner? Verified, controlled out-of-body experiences during near-death episodes — scientists found that scenario the most potentially convincing. A worldwide survey of nearly 2,400 people also delivered a surprising finding: while 60-70% of people are often cited as believing in survival after death, the number drops to around 40-50% when you ask specifically about personal identity surviving — not just some vague cosmic energy, but you actually continuing as you.

Research Notes

IONS team's 2021 Bigelow essay contest entry applying a structured evidence-grading approach. The A–F framework adapted from medical research is the clearest attempt to operationalize evidential standards for survival research. The survey of 422 academics provides unique empirical data on scientific persuasion thresholds. Note: PDF filename incorrectly uses 2025; actual publication year is 2021.

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). A worldwide belief survey (N=2,389) finds the commonly cited 60–70% survival belief rate overstates identity-preserving (Level 2+) belief, which is closer to 40–50%.
