Tremor in the Blood: Uses and Abuses of Lie Detectors - Softcover
The author presents case histories of persons whose lives have been blighted by our uniquely American faith in the myth of the lie detector. Dr. Lykken also explains how to "beat" the machine, not only because it is unfair that spies and Mafia soldiers already know these techniques, but also because innocent persons have nearly a 50:50 chance of failing lie detector tests unless they use appropriate countermeasures. Many state courts in the U.S. still admit lie detector tests into evidence under certain conditions - a practice that ensures the conviction of more innocent people every year. Finally, Dr. Lykken reports on the results of recent surveys of informed scientific opinion about lie detection and presents another method of polygraphic interrogation that is designed to detect, not lies, but the presence of guilty knowledge. This method is scientifically credible and holds promise for future use in criminal investigation.

From Library Journal:
Lykken, a well-known polygraph expert, dismantles many myths of lie detector tests and practices and allows us to evaluate assumptions surrounding these tests, which measure variations in an individual's emotional stress. Seventeen years after the book's first edition (LJ 10/1/80), he offers a work to reflect substantial changes in truth detection technology during that period, tracing the historical and scientific background of lie detection based on different polygraph tests. Lykken critically examines many tools designed to verify the truth and finds no specific response in the scientific literature. He offers his own Guilty Knowledge Test (GKT) as based on sounder psychological principles than the dominant polygraph Control Question Test (CQT). Lykken argues that GKT has an ability to detect both guilt and innocence. Individuals interested in legal and criminal matters and social and psychological testing will welcome this book.
