John E. Reid was an American polygraph expert and the creator of the Reid Technique, a widely used method of interrogation. Born in 1910, he developed this technique in the 1950s, emphasizing psychological manipulation to elicit confessions from suspects. His approach focuses on understanding human behavior and the psychological aspects of lying. Reid founded the John E. Reid and Associates in 1947, which trained law enforcement personnel in interrogation methods. His work has been influential in criminal justice, although it has also faced criticism regarding its effectiveness and ethical implications. Reid passed away in 1982, leaving a lasting impact on interrogation practices.
