Polygraph is used to determine intentional deception regarding a very specific issue. It is not used to determine general honesty, sincerity or integrity. Part of what makes polygraph testing work is "fear of detection" by a person trying to conceal involvement in or knowledge of a specific event. This fear of detection triggers a reaction in the sympathetic nervous system (SNS) which polygraph examiners are trained to identify. The frequency, location and intensity of these reactions in a polygraph exam are used to develop a numerical score, and this score is used to determine the probability of deception. The more specific the questions, the more reliable the results will be. You can not ask someone "Are you an honest person?" because this is subjective to the point of view of the person taking the test. - Michael Martin (President, Global Polygraph Network)

What are the basic functions of the polygraph and its legal status in the courts?

In police work, the two major uses of polygraph testing are specific issue testing and preemployment screening.

Polygraph testing can help to verify information collected during traditional background investigations and to uncover information not otherwise available. The commonly held belief that polygraph examination results are not admitted into evidence in court is untrue. Some courts admit polygraph evidence even over the objection of counsel; in other jurisdictions, polygraph results are admitted by stipulation
