Failing the future: Three unsuccessful attempts to replicate bem's 'retroactive facilitation of recall' effect

Abstract

Nine recently reported parapsychological experiments appear to support the existence of precognition. We describe three pre-registered independent attempts to exactly replicate one of these experiments, 'retroactive facilitation of recall', which examines whether performance on a memory test can be influenced by a post-test exercise. All three replication attempts failed to produce significant effects (combined n = 150; combined p =. 83, one-tailed) and thus do not support the existence of psychic ability. © 2012 Ritchie et al.
