Concerns Replication Status
Currently States Three pre-registered direct replications by Ritchie, Wiseman, and French found no effect; the original journal declined to publish the null replications without external review.
Daryl Bem, at Cornell University, published nine precognition experiments in the Journal of Personality and Social Psychology in 2011, reversing the time order of standard priming, habituation and recall paradigms so the causally relevant event occurred after the response it was said to influence. Stuart Ritchie, Richard Wiseman and Christopher French ran three independent, pre-registered attempts to replicate one of Bem's nine experiments using his own published procedure, and all three were null. The method on both sides is controlled psychological experiment using the identical published protocol, so the replication attempts tested Bem's own procedure directly. Because the failure occurred in pre-registered replications specifically designed to close the analytic-flexibility concerns raised against the original paper, the case is widely cited as a catalyst for the wider reform of psychological research methods, pre-registration and multi-lab replication, that followed it, and the replication status is recorded as debunked on the direct replication evidence.
