How can an evangelist convert a hardboiled sophisticate? Why does a POW sign a "confession" that he knows is false? How is a criminal pressured into admitting his guilt? Do the evangelist, the POW's captor and the policeman use similar methods to gain their ends? These and other compelling questions are discussed in this definitive work by William Sargant. Sargant explains and illustrates the basic techniques used by evangelists, psychiatrists and brainwashers to dissolve existing, established patterns of belief and then to substitute new beliefs and behaviors.
