Snapping: America's Epidemic of Sudden Personality Change

Blurb

Snapping: America's Epidemic of Sudden Personality Change is a 1978 book which describes the authors' theory of religious conversion. They propose that "snapping" is a mental process through which a person is recruited by a cult or new religious movement, or leaves the group through deprogramming or exit counseling. Political ideological conversions are also included, with Patty Hearst given as an example.
Two editions of the book were published, the first by Lippincott Williams & Wilkins; and reprinted in 1979 by Dell Publishing; and a second edition by Stillpoint Press, a publishing company owned by the authors.
