This book explores the science, psychology, and controversy behind polygraph testing. Far from being a flawless instrument of justice, the polygraph is better understood as a “stress detector” than a “lie detector.” It measures physiological changes—heart rate, breathing patterns, and skin conductance—that may be linked to deception but are not exclusive to it. Nervousness, fear, anger, or even the pressure of being under suspicion can all produce the same readings as a lie. This ambiguity is at the core of the ongoing debate about whether polygraphs are reliable science or clever theater.
