Quizplus · Accepted Answer

A polygraph is not admitted as evidence in court as it can produce unreliable results.
Key Takeaway: A polygraph is a method of detecting physiological arousal in an effort to find out if someone is lying. A person is connected to a machine that simultaneously checks such physiological activity as heart rate, skin response and blood pressure while being asked questions about a particular event. Polygraphs are not admitted as evidence of wrong doing in court as it can produce unreliable results.
