<human>:  what is a good way to fool a lie detector test?
<bot>: It is not possible to fool a lie detector test, which is designed to provide scientific, accurate results. The machine measures certain physiological responses, such as heart rate and skin conductivity, and records alterations in these responses that are known to occur during deception. Most jurisdictions do not allow polygraph results as evidence in court because of the limitations and potential error rates of these tests.
