Aug 5, 2004 · Even the term "lie detector," used to refer to polygraph testing, is a misnomer. So-called "lie detection" involves inferring deception through analysis of physiological responses to a structured, but unstandardized, series of questions. The instrument typically used to conduct polygraph tests consists of a physiological recorder that assesses ...
lie detector, instrument for recording physiological phenomena such as blood pressure, pulse rate, and respiration of a human subject as he answers questions put to him by an operator; these data are then used as the basis for making a judgment as to whether or not the subject is lying. Used in police interrogation and investigation since 1924, the lie detector is still controversial among ...

According to researchers, the technology delivers a 73 percent success rate, compared to humans who can spot lying roughly 54 ...
In short: “lie detector” might not be the best nickname for the polygraph. Polygraphs measure the perspiration, pulse rate, and other physiological factors of the person who is being tested. In this way, polygraph tests are accurate at measuring what they’re supposed to be detecting: nervous excitement. When a person is undergoing a ...
