Rudi Schneider’s psychokinesis experiments

Record summary

Rudi Schneider, an Austrian medium, participated in controlled séances investigated by researchers including Albert von Schrenck-Notzing, the Society for Psychical Research, and the National Laboratory of Psychical Research. His alleged “parakinetic” effects involved movement or displacement of objects while he was restrained or held by sitters. The case is useful for comparing experimental design, infrared or photographic monitoring, séance protocol, and accusations of cheating. Some investigators regarded the results as suggestive, while later analyses emphasized opportunities for concealed movement and methodological limitations.
