Is there a way to determine if a person is lying?
assistant
Yes, there are several ways to detect lies. One method is to look for discrepancies between what the person says and their body language or facial expressions. Another approach is to use polygraph tests, which measure physiological responses such as heart rate, blood pressure, breathing, and skin conductivity. These methods can be used in combination with other techniques, such as asking follow-up questions to probe further into the truthfulness of the statement.
