In reply to the discussion: Michael Flynn says Mar-a-Lago staff should be subjected to polygraph tests to catch Trump cabinet pick 'leaker' [View all]TomWilm

Most psychologists and other scientists agree that there is little basis for the validity of polygraph tests.
A particular problem is that polygraph research has not separated placebo-like effects (the subject's belief in the efficacy of the procedure) from the actual relationship between deception and their physiological responses. 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.
Without a better theoretical understanding of the mechanisms by which deception functions, however, development of a lie detection technology seems highly problematic. For now, although the idea of a lie detector may be comforting, the most practical advice is to remain skeptical about any conclusion wrung from a polygraph.
