EST (Erhard Seminars Training)
A therapeutic movement founded by Werner Erhard (Jack Rosenberg), a salesman, and based on consciousness training programs and psychology-of-success literature. EST was incorporated as an educational corporation and employed techniques drawn from Scientology, Zen, Dale Carnegie, and humanistic psychology; thus it accommodates elements associated with oriental mysticism to the American success ethic. EST was widely criticized for sanctifying selfishness and for abrasive and traumatic training sessions. Highly successful in the late 1970s, EST was later officially discontinued and replaced by a new organization, the Forum.
