A Preregistered Direct Replication of Bem’s Retroactive Facilitation of Recall Effect

Record summary

Ritchie, Wiseman, and French published a preregistered direct replication of one of Bem’s controversial retroactive-effects experiments. The study is an identifiable counterpoint to the original Cornell work and is useful for comparing preregistration, sample size, analysis decisions, and replication outcomes in anomalous-cognition research. Its relevance to this domain lies less in a positive paranormal result than in showing how a high-profile precognition claim was tested under tighter controls. Researchers should distinguish the replication’s publication venue and authors’ locations from the broader North American controversy.
