The Edinburgh Mediumship and Anomalous Information Studies

Record summary

Researchers associated with the Koestler Parapsychology Unit investigated anomalous information reception, psychic readings, and experimental designs intended to reduce ordinary information transfer. These studies are relevant because they moved mediumship-related questions toward blinding, target selection, rating procedures, and statistical analysis. The literature is heterogeneous and should not be summarized as one successful programme. Important uncertainties include sensory leakage, experimenter effects, selective reporting, subject expectancy, and whether above-chance scoring reflects psi or methodological artifacts.
