Here is a practical guide to detecting lies that reads like a spy novel! And it is not surprising: the practices, ideas, methods described here were discovered not by psychologists in cozy offices and university classrooms, but by CIA officers during interrogations of foreign intelligence agents and suspects of serious crimes. The authors of this amazing guide are not scientists, but experienced practitioners who for decades they conducted confrontations, recruited agents and tracked down spies. They learned to feel a lie, see it, understand its essence. From this knowledge and observations of people’s behavior, their verbal and non-verbal signals, the Lie Detection System arose. The system was tested many times by the CIA and acquired a huge number of followers in other areas - employees of law firms, large corporations, and financial companies on Wall Street became its fans.
