The Science of Lie Detection

This book investigates the science, psychology, and controversy surrounding the polygraph, often known as the "lie detector," highlighting its nature as a stress detector rather than a definitive tool for uncovering deception. It explores the limitations of the device, the influence of human judgment, and the ongoing debate about its reliability and legal acceptance, while also examining emerging technologies like brain imaging. Balancing critique and insight, the book offers a nuanced understanding of the polygraph's cultural significance and its place in the wider quest to distinguish truth from lies.
