Welcome to the Psi Encyclopedia! We aspire to provide a comprehensive introduction to academic parapsychology, which studies the range of psychic experiences collectively termed ‘psi’.  The existence of psi phenomena – and the related idea that consciousness is independent of the physical body and so may survive death – is strongly disputed by materialist scientists, yet parapsychologists are convinced they have evidence for these things. The Psi Encyclopedia presents this evidence in nearly 750 signed articles by over 80 authors, many of them senior academics, arranged in categories and subcategories that highlight the major interests of the field. It is sponsored by the Society for Psychical Research.

Mark Boccuzzi created this short video that explains what we are about.

ESP & Psychokinesis

Extra-sensory perception (ESP) comprises telepathy, clairvoyance and precognition. Psychokinesis (PK) is the direct influence on matter by mind alone. Both ESP and PK have been tested in the laboratory and studied in real life situations. Together they constitute psi, in the strict sense of the term. Subcategories group together overviews and general topics in psi studies, tests of ESP and PK, and researcher biographies.
