Abstract

Across seven experiments (N = 3,289) we replicate the procedure of Experiments 8 and 9 from Bem (2011), which had originally demonstrated retroactive facilitation of recall. We failed to replicate that finding. We further conduct a meta-analysis of all replication attempts of these experiments and find that the average effect size (d = .04) is no different from zero. We discuss some reasons for differences between the results in this paper and those presented in Bem (2011).

Keywords: esp, psi, precognition, failure to replicate
