Question

Quizplus · Accepted Answer

Lie detectors, or polygraphs, do not directly detect lies. Instead, they measure physiological responses such as heart rate, blood pressure, and sweating, which may change when a person is lying. However, these physiological responses can also change due to nervousness, anxiety, or other reasons unrelated to lying, making it inaccurate to say that lie detectors directly detect lies.
