Alice-in-Wonderland terminological usage in, and communicational concerns about, that peculiarly American flight of technological fancy. The CQT polygraph

Abstract

Alice-in-Wonderland (AW) terminological usage employs basic terms in a systematically misleading and taxonomically anarchic way. The so-called "control" question "test" (CQT) polygraph procedure, which enjoys a controversial but nevertheless scientific status in North America, involves such AW terminological usage. The basic concepts of "test," "control," and "quantification" are loosely employed. There is loose talk about the "detection of deception," which generates the paradox that in the CQT it is in the innocent that deception should be detected. Moreover, deception is not really assessed either in the CQT or in the more scientically-based Guilty Knowledge Test (GKT). Finally, there is loose practice in evaluating the CQT, which should not be primarily assessed in terms of its overall accuracy, but in terms of its specific effects in improving accuracy through the provision of physiological information to the examiner. Such as assessment has not been carried out even in laboratory analogues of polygraphy. The treatment of the CQT exemplifies most psychophysiologists' reluctance to treat basic definitional issues seriously, and also means that opponents of the CQT are unable to communicate clearly about it with non-psychophysiologist professionals and with the lay community.
