With regard to the polygraph, ______.

Question

Quizplus · Accepted Answer

The polygraph, commonly known as a lie detector test, does not measure brain wave activity but physiological responses such as heart rate, blood pressure, and sweating. The Comparison Question Test (CQT) technique is indeed more prone to false-positive errors, where truthful individuals are incorrectly identified as being deceptive, than to false-negative errors, where deceptive individuals are incorrectly identified as truthful. The RIT (Relevant/Irrelevant Test) is not the most common method; the CQT and the Guilty Knowledge Test (GKT) are more widely used. Lastly, the claim that the polygraph is 99.9 percent accurate is false; its accuracy is a subject of considerable debate among scientists and legal experts, with many questioning its reliability and validity in detecting deception.
