Thought reform is accomplished through the use of psychological and environmental control processes that do not depend on physical coercion. Today's … - Margaret Singer

The term "cult" is always one of individual judgment. It has been variously applied to groups involved in beliefs and practices just off the beat of traditional religions; to groups making exploratory excursions into non-Western philosophical practices; and to groups involving intense relationships between followers and a powerful idea or leader. The people I have studied, however, come from groups in the last, narrow band of the spectrum: groups such as the Children of God, the Unification Church of the Reverend Sun Myung Moon, the Krishna Consciousness movement, the Divine Light Mission, and the Church of Scientology. I have not had occasion to meet with members of the People's Temple founded by the late Reverend Jim Jones, who practiced what he preached about being prepared to commit murder and suicide, if necessary, in defense of the faith.

While everyone is influenced and persuaded daily in various ways, vulnerability to influence fluctuates. The ability to fend off persuaders is reduced when one is exhausted, rushed, stressed, uncertain, lonely, indifferent, uninformed, aged, very young, unsophisticated, ill, brain- damaged, drugged, drunk, distracted, fatigued, frightened, or very dependent.

I started hearing from families who had missing members, many of them young kids on our campus, and they all would describe the same sorts of things. A sudden change of personality, a new way of talking...and then they would disappear. And bingo, it was the same sort of thing as with the Korean War prisoners, the same sort of thought-reform and social controls. You find it again and again, any time people feel vulnerable. There are always sharpies around who want to hornswoggle people.
