How can you know you’re being lied to? Does a close friend lie? A spouse? A child? Does someone hide something and insistently deny everything in a way that makes you doubt yourself: “Is he lying?”
Georges Dupré, a well-known French psychologist and sociologist, offers several fairly simple “recipes” that, after minimal training, using analysis of verbal and nonverbal cues, make it possible—with a high degree of probability—to distinguish truth from lies. And it doesn’t matter whether the falsehood was intentional (planned, deliberate) or unconscious; whether it was carried out not only as a verbal act, but also through nonverbal means of communication.
In addition, the author is interested in the very essence of lying and deception, as well as the moral and psychological aspects of this—both theoretical and practical sides of the issues related to manipulation, fraud, misleading people, and ways of implanting falsehood in modern society.
