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.

British medium whose materialisation séances attracted both supporters and critics.

This category contains articles that treat consciousness in relation to the body. Subcategories focus on consciousness and psi; dreams and psi; and distant healing and psychotherapy. Also included are sitter groups and macro-psychokinesis as well as poltergeists, often assumed to relate to discarnate entities but now known more often to have living agents. A final subgroup is concerned with out-of-body and near-death experiences and events reported on the threshold of death.

Survival of Death

Life continued in a spiritual or purely mental form after bodily death is a staple of religious beliefs worldwide, and likely is as old as humanity.

Subcategories focus on hauntings and apparitions and on psychic (also called mental) mediumship.

Reincarnation

Reincarnation beliefs are widespread in the world and in recent decades researchers have found what they believe is evidence of them through the study of people (mainly children) who claim to have lived before. Subcategories highlight case studies, past life regression, and biographies of major researchers.
