Lie detector tests

CartoonPolygraph exams are often referred to as lie detector tests. The term ‘lie detector testing’ is thought to have originated from a nickname given to the instrumentation used by the polygraph examiner. The polygraph instrument records various aspects of your body's Sympathetic and Parasympathetic Nervous Systems.

It is often called the ’lie detector’ because it picks up changes in these systems when a person makes an untrue statement. However, polygraph experts say it would be more appropriate to call the test a truth verifier rather than a lie detector test.
