The polygraph, often portrayed as a magic mind-reading machine, is still controversial among experts, who continue heated debates about its validity as a lie-detecting device. As the nation takes a fresh look at ways to enhance its security, can the polygraph be considered a useful tool? The Polygraph and Lie Detection puts the polygraph itself to the test, reviewing and analyzing data about its use in criminal investigation, employment screening, and counter-intelligence. The book looks at: The theory of how the polygraph works and evidence about how deceptivenessâ€"and other psychological conditionsâ€"affect the physiological responses that the polygraph measures. Empirical evidence on the performance of the polygraph and the success of subjects' countermeasures. The actual use of the polygraph in the arena of national security, including its role in deterring threats to security. The book addresses the difficulties of measuring polygraph accuracy, the usefulness of the technique for aiding interrogation and for deterrence, and includes potential alternativesâ€"such as voice-stress analysis and brain measurement techniques.

"Polygraphy;' "lie detection;' and the "detection of deception" are all terms that refer to an application of the science of psychophysiology, which itself employs physiological measures to study and differentiate between psychological processes. The issues raised by polygraphy are controversial. One such issue is whether the polygraph is a genuinely scientifically based application, or merely a purported application, of psychophysiology. Such concerns are of interest not only to polygraph practitioners and to specialists in psychophysiology, but also to such other specialists as those in the legal and forensic professions. Moreover, there are two sorts of nonspecialists who should also be concerned. On the one hand, there are the potential "users" of the polygraph-for example, a manager who employs a polygrapher to check on subordinates; on the other hand, there are those "used by" the polygraph - the employee who is subjected to the poly graphic examination. To begin with the user of the polygraph, this person should know not only about its overall accuracy, but also about the rationales of the various detection methods and their validity for different purposes in different sorts of situations. This infor mation is important, because even for the potential user there are costs as well as benefits. Aside from the lack of trust generated by the polygraph, there have also been successful suits by employees against employers, so there are traps in polygraph usage that employers (and managers) need to keep in mind.
