Question

Quizplus · Accepted Answer

Lie detectors, also known as polygraphs, measure physiological responses (like heart rate, blood pressure, and perspiration) that are believed to change when a person is lying. However, these physiological responses can vary for reasons other than lying, making it inaccurate to claim that lie detectors directly detect lies. They do not directly measure truthfulness; instead, they monitor physical indicators that might be associated with deceptive behavior.
