Lie detector tests, also known as polygraph tests, are used to measure physiological responses such as heart rate, blood pressure, and skin conductance to determine if a person is telling the truth or lying.

False Negatives: These occur when the polygraph fails to detect lies and wrongly concludes that someone is telling the truth.
Invasion of Privacy: The use of lie detector tests can be seen as an invasion of privacy since it involves monitoring personal physiological responses without consent.
