I became a credentialed "forensic psycho-physiologist" some 12 years ago, after completing my studies at the Backster School of Lie Detection in November of 2004. Since that time, as a member of the American Polygraph Association, I've conducted countless polygraph "tests" of many types. My exposure to the world of polygraph whoredom has been interesting, but it's time to move on. Effective January 1st, 2017, I am retiring from the polygraph indu$try. Over the years I became increasingly disenchanted, if not disgusted, with the polygraph indu$try -- and for good reasons. Here are my main complaints, which became irrevocably cemented after spending a dozen years in the polygraph trenches -- five of which were spent running PCSOT exams behind the walls in a state prison. In my view... * Polygraph "testing" is a SWAG -- a scientific wild-ass guess; there is precious little foundation for the CQT * Accuracy claims proffered by pro-polygraph organizations are not realistic and thus should not be believed * The polygraph indu$try cares very little about victimization and its attendant collateral damage * A bill of rights for polygraph test-takers is long overdue * Polygraph "testing" is mainly about one thing: MONEY Anyone contemplating taking a polygraph "test" -- or who is a secondary consumer of the polygraph indu$try's products or services -- should enlighten themselves by reading four most informative books. They are: The Lie Detectors: The History of an American Obsession by Ken Alder Gatekeeper: Memoirs of a CIA Polygraph Examiner , by John F. Sullivan The Polygraph and Lie Detection , published by the National Academies Press The Lie Behind the Lie Detector, by George W. Maschke and Gino J. Scalabrini Effective January 1st, 2017 I will no longer be a participant on this or any other polygraph-oriented web site. However, I will remain available for select consultation -- in person only -- on a very limited basis. Thanks to all who engaged me here on the antipolygraph.org forum. That said, I deeply regret that I never got to meet a polygraph realist of the highest stature -- Drew Richardson. His views, teachings, experience and encouragement were most influential to me. Rest in peace, Drew. Lastly, if you can avoid taking a polygraph "test," do so. If you have little or no choice, learn everything you can about the process before you take the "test." Goodbye and good luck. Happy Christmas to all, and to all a good night! Dan Mangan
