Subsection 4 is titled "Countermeasures and/or Creating Truthful Charts." Dean writes: Quote:
Dean's claim that "Invariably the examiner is better at catching countermeasures than a person is at doing them" reflects a common conceit of the polygraph community. However, in peer-reviewed laboratory studies conducted by Professor Charles R. Honts of Boise State University, polygraph examiners were not able to detect sophisticated countermeasures attempts at better than chance levels. (See the bibliography of The Lie Behind the Lie Detector for citations and abstracts.) If you have mastered the polygraph countermeasures explained in Chapter 4 of The Lie Behind the Lie Detector, you will only be "caught" using countermeasures if you admit to using them. Section VI, "Did I Pass or Fail," addresses the question, "Why is it so hard to get a straight answer from a polygraph examiner about whether or not you passed or failed?" Dean dances around this question, but notes that one reason is that a person who "passes" the test may nonetheless have made disqualifying admissions. She concludes this subsection stating: Quote:
I suspect that it would be counterproductive to ask one's polygrapher, "Did you observe any deceptive reactions?" The presence or absence of a post-test interrogation is a good indication of whether the polygrapher observed what he/she thought were "deceptive reactions." Section VII, "What Can I Do if I 'Fail' the Test," suggests looking into different departments if you made disqualifying admissions, and requesting an issue-specific polygraph if "you failed the test because you had 'deceptive reactions.'" Section VIII, "A Few Words of Advice" provides admonishments to be truthful, summing it all up with "INTEGRITY AND CREDIBILITY are the most important characteristics established during the polygraph exam. These characteristics are practically irreplaceable. Once you compromise your integrity, it is near impossible to gain it back." The polygraph community would do well to take this advice to heart. Section IX, "Non Police [sic] Officer Applicants" lets readers who are applying for jobs as dispatchers, firefighters, or security guards know that the polygraph procedure for them will be similar to that for law enforcement applicants. Section X, "How Does All This Apply if I'm to Take a Voice Stress Analysis? [sic]" notes, "Polygraph measures physiological responses. Certain responses or patterns of responses have been identified as being indicative of deception. A VSA, as the name implies, measures STRESS. Therefore, in a VSA test nervousness CAN BE A FACTOR. This is one of the major drawbacks to this technology. If you have any problems with a VSA test, demand a polygraph test." Here again, Dean repeats the untruth that nervousness cannot affect the outcome of a polygraph "test." It can, and both polygraphy and voice stress analysis are unsupported by peer-reviewed scientific research. Nonetheless, Dean's advice of demanding a polygraph "test" if you have any problems with a (C)VSA "test" is not without merit. Effective countermeasures for polygraph "tests" exist (see Chapter 4 of The Lie Behind the Lie Detector), but as far as I know, no reliable countermeasures for CVSA "tests" have been identified. continued in following post... |
