Does Psi Exist? Replicable Evidence for an Anomalous Process of Information Transfer

Does Psi Exist? Replicable Evidence for an Anomalous Process of Information Transfer, by Daryl Bem and Charles Honorton, published in Psychological Bulletin in 1994, is a peer-reviewed meta-analysis of ganzfeld telepathy studies arguing the pooled results showed a small but statistically significant and, the authors argued, replicable effect. As a peer-reviewed article in a major psychology journal it is the correct source for what that particular meta-analysis actually found and argued. Its limit is substantial: the ganzfeld effect it reports has not been reproduced to the field's satisfaction in later, more rigorously pre-registered replications, and Bem's own later psi research became a central example in psychology's replication crisis, so this article's conclusion should be presented as a contested claim from the parapsychological literature, not as an established finding.
