Plain English Summary

Can psychic mediums really pick up information about deceased people? This study put twenty mediums to a tough test -- five layers of blinding that shut down every normal explanation, from cold reading to experimenter bias to fraud. Each medium got nothing but a dead person's first name over the phone. Blinded raters then tried to tell their own reading from a decoy. The results were striking: mediums scored accurate details 53% of the time versus 37% for decoys, and raters correctly identified their reading 66% of the time (chance is 50%). The effect size matched an earlier 2007 study almost exactly. The catch? All data comes from one lab, so independent replication would really strengthen the case.

Research Notes

Most rigorously blinded mediumship accuracy study in the literature, with five levels of blinding that address all major conventional explanations. Replicates Beischel & Schwartz 2007 global score (both d = 0.57) and forced-choice (both p = .01). All data collected by Windbridge group; no independent replication exists. Funded by Windbridge Institute and BIAL Foundation.

Twenty Windbridge Certified Research Mediums performed 96 phone readings (86 usable) between 2009 and 2013 in three experiments of increasing rigor. Under quintuple-blind conditions eliminating cold reading, rater bias, experimenter cueing, and fraud, mediums were given only a discarnate's first name. Blinded sitters scored target and decoy readings. Calculated item accuracy was significantly higher for targets (52.8% vs. 36.6%, p = .002, d = 0.75), hits vs. misses showed large differences (chi-squared = 66.69, p < .0001), global scores favored targets (2.88 vs. 2.09, p = .001, d = 0.57), and forced-choice selections were significant (38/58 = 65.5%, p = .01). Results replicate the original 2007 AIR study.
