Extra-Sensory Perception

Record summary

J. B. Rhine’s Extra-Sensory Perception presented card-guessing experiments at Duke University involving telepathy, clairvoyance, and precognition. The book helped establish “ESP” as a standardized parapsychological research category and emphasized statistical scoring rather than séance phenomena. It is central for comparing altered-state claims with laboratory protocols, but methodological criticisms include sensory leakage, optional stopping, subject selection, and replication difficulties. Later experiments and meta-analyses should be checked before treating Rhine’s reported deviations from chance as secure evidence of psi.
