From this very interesting book-length article: "Professors William G. Iacono and David T. Lykken of the University of Minnesota provided important comments on our chapter on polygraph countermeasures." Professor Iacono is an occasional, always thoughtful, participant in the "journal club" on behavior genetics in the University of Minnesota Department of Psychology that I join during each school year. The late Professor Lykken himself wrote a whole book on why polygraph examinations are a bad idea, http://www.amazon.com/A-Tremor-In-The-Blood/dp/0306457822 http://www.amazon.com/A-Tremor-In-The-Blood/dp/0306457822 and his writings helped convince the Minnesota legislature not to allow polygraph results for any judicial or employment-screening purpose in the state. It's ludicrous that the federal government and some state judicial systems still rely so much on such an inherently unreliable, unvalidated technology. "We are especially grateful to retired FBI Supervisory Special Agent Dr. Drew C. Richardson for his suggestions regarding the second edition of this book." Yes, after being burned by false polygraph results many times, SOME (but not enough) federal law enforcement agents are recognizing that polygraph examinations are useless for finding the truth.
