Paranormal Beliefs and the Barnum Effect

The acceptance phenomenon (i.e., the general tendency for persons to accept almost any bogus personality feedback; Layne, 1979) may be related to certain paranormal beliefs (Alcock, 1981; Hyman, 1981). Paranormal beliefs are beliefs in phenomena that, if authentic, violate basic limiting principles of science (Broad, 1953; Tobacyk & Milford, 1983). One specific illustration of the acceptance phenomenon is the "Barnum effect," which refers to acceptance of bogus personality feedback consisting of relatively trivial statements with a high base rate (Layne, 1979; Snyder, Shenkel, & Lowery, 1977). The Barnum effect has been implicated in personal validation and in "cold reading," both of which are used routinely by many astrologers, clairvoyants, faith healers, fortune tellers, graphologists, mediums, Tarot Card readers, and others (Hyman, 1981). It was hypothesized that paranormal beliefs emphasizing divinatory procedures that produce personalized feedback (i.e., precognition, spiritualism, superstition, and witchcraft) are associated with greater susceptibility to the Barnum effect.
