ESP & Parapsychology practice

The history and methods of parapsychology — the century-long attempt to test claims of ESP (extrasensory perception) under controlled conditions. Learn the vocabulary (telepathy, clairvoyance, precognition, psychokinesis), the Society for Psychical Research and early psychical research, J. B. Rhine’s card-guessing experiments with Zener cards and the statistics behind them, sensory leakage and the controls designed to stop it, the Ganzfeld experiments and the meta-analysis debates over them, remote viewing and the government’s Stargate program and its 1995 evaluation, Daryl Bem’s 2011 precognition studies and their role in psychology’s replication crisis, random-number-generator studies, and the documented cases of fraud and experimenter effects. Practice the statistics that decide these debates — the file-drawer problem, optional stopping, multiple comparisons and prior probability — and the psychology of why coincidences feel meaningful. Psi is taught as a set of claims and a research record, never as an ability to develop, and the keyed answer is always the evidence-based one. Distinct from Paranormal Claims (the broad survey of ghosts, psychics and the unexplained): this goes deep on the experiments themselves. Educational — the science of the claims, taught fairly.
