An honest person may be nervous when answering truthfully and a dishonest person may be non-anxious. Proponents say that laboratory studies of polygraph exams using the “control question technique” were very accurate with precision in the region of 87 percent (Abrams, 1989). According to research noted by the American Polygraph Association (APA) website on polygraph validity: “The data show that techniques intended for event-specific (single issue) diagnostic testing produced an aggregated decision accuracy of 89% (confidence interval of 83% – 95%), with an estimated inconclusive rate of 11%. “Proponents will say the test is about 90% accurate.

2016-09-20 · The American Polygraph Association, which sets standards for testing, says that polygraphs are "highly accurate," citing an accuracy rate above 90 percent when done properly. Critics, however, say the tests are correct only 70 percent of the time. Polygraph tests often include a procedure called a “stimulation test,” which is a demonstration of the instrument’s accuracy in detecting deception.

The combination of all validated PDD techniques, excluding outlier results, produced a decision accuracy of 87% (confidence interval 80% - 94%) with an

10, p 4). A lie detector test measures physical and emotional responses to approximately 10 predetermined questions, according to the Global Polygraph Network. Drugs may affect the test but usually with an inconclusive result. Generally, drugs that affect the nervous system may alter the test's measured responses. Polygraph testing, for example, is used as a direct measure of physiological Polygraph accuracy is the extent to which test results correspond to truth with 15 Dec 2014 Experts conclude that polygraph tests probably are beatable by people with training, a belief demonstrated by the federal government's recent PDF | The accuracy of the control question polygraph test with psychopaths was evaluated within a realistically threatening context.

One reason that polygraph tests may appear to be accurate is that subjects who believe that the test works and that they can be detected may confess or will be very anxious when questioned. If this view is correct, the lie detector might be better called a fear detector.

Reports of accuracy range from around chance to near 100 percent. 10 However, a thorough and definitive review of the research literature carried out by a committee of the National Research Council concluded that polygraph accuracy is in the region of 81 to 91 percent, which the reviewers described as “well above chance, though well below perfection” (Ref. 10, p 4).
