Polygraph testing other know as Lie Detection test is the practice of detecting lies told by the stating party.
In simple terms you hook up a device to a person and ask a series of questions. The device will then indicate when a answer is a lie or if the truth is told.
Types of Polygraph Testing
Reliability of Polygraph Testing
Because the polygraph test measures bodily responses, a data subject can attempt to alter her bodily responses in order to interfere with the test. Several common ways to undermine the test include: taking sedatives to reduce anxiety; using antiperspirant to prevent sweating; and positioning pins or biting parts of the mouth after each question to demonstrate a constant physiological response.
