A non-committal technical term used to refer to instances of extrasensory perception in which the information paranormally acquired may have been derived either from another person’s mind (that is, as telepathy), or from a physical event or state of affairs (that is, as clairvoyance), or even from both sources; experimental parapsychologists rarely use the term “telepathy” because of the difficulty, in tests of so-called telepathy, of excluding the possible operation of clairvoyance.
