NOTE: Laboratory studies have been criticized as lacking the emotional involvement of real-life examinees whose fear of detection or error is proportionate to the dire consequences, usually imprisonment and its attendant perils. For a full discussion on the merits and pitfalls of laboratory studies versus field studies, you are invited to read “Guiding Principles and Benchmarks for the Conduct of Validity Studies of Psychophysiological Veracity Examinations Using the Polygraph” published on this website. The Army Modified General Question Technique also known as the MGQT cited above is still used in the public and private sectors in spite of its dismal record in the identification of Truthful cases (25% correct) and an overall accuracy of 61% correct decisions.
