Showing results for "Science" in Criminal & Forensic Psychology

Jana Monroe was no ordinary cop: a cofounder of - and, at the time, the only female agent in - the world-renowned FBI Behavioral Sciences Unit at Quantico, over the course of her career she consulted on more than 850 homicide cases. But to the people who know her best, Monroe is the BSU analyst upon whom the film character of Clarice (Jodie Foster) in The Silence of the Lambs was modeled. Hearts of Darkness is Monroe's story and will have Monroe finally stepping out from the shadows to tell the range of remarkable tales from the top moments of a life chasing the monsters among us.

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.
