Should you take a lie detector test?
When detectives ask you to take a lie detector test, you can assume that they are trying to gather evidence, usually against you. Sometimes a suspect asks for evidence to prove his innocence. You are never legally required to take a lie test in a criminal investigation.
What exactly happens during a lie detector test?
They actually measure several indicators, such as heart rate, blood pressure, skin conductance and respiration, which when analyzed indicate whether the person being tested is lying. There are many studies showing how people react when they lie, and it is clear that they cannot hide their emotions the way they would like.
