Parapsychologists commonly use the term psi as shorthand for psychic phenomena. The latter include the three main categories of extrasensory perception (ESP): telepathy, clairvoyance, and precognition; plus psychokinesis as well as all related psychic experiences, including remote viewing, near-death experiences, and out of-body experiences. The term PSI was first used in 1942 in a minor publication on ESP, but it was popularized by parapsychologist J.B. Rhine beginning in 1948.
