OK, George, I have a few moments now to respond thoughtfully to your post.
First of all, a confession. When I made the post you quoted--which was, I recall, my first post on this forum--I wanted to appear as just another anxious, worried visitor. I fully expected that none other than you, George, would reply to it, since it expresses apparent ignorance with regard to the polygraph, and I knew someone like you probably could not resist a chance to address my feigned ignorance and perhaps develop another unwitting convert to your cause. Truth be told, I know all the answers to each question that I asked in that first post; however, I thought I'd ask those seemingly ignorant questions as a way of dipping a toe in the water, so to speak, to discover its true temperature. In other words, I wanted to test you, George, in order to ascertain just how much true knowledge you had vs. how much tired, unfounded rhetoric you might also have. I'm pleased to announce that my post had its desired effect. You actually do possess some knowledge of the polygraph, albeit regurgitated knowledge you have obtained from books rather than actual experience. In fact, I have little argument with some of your statements, which proves that you reguritate quite well.
Of course, if we both just sit here and regurgitate, I think we'll make everyone sick, but sometimes it takes reguritation to fight regurgitation.
At least my reguritation is backed up by actual experience.
That said, I'll take a few moments to respond to your response. I won't really address all of your responses, since I already know the answers to my own questions. However, I'd like to discuss countermeasures a bit.
With regard to countermeasures, there are several studies--some old, some new--to which I may refer you. These studies are based almost entirely on laboratory experiments, upon which the "anti-" crowd-- such as yourself--so often rely. I question the credibility and practicality of applying any laboratory study of the polygraph to the real world, but since the "anti-" crowd really has nothing but laboratory studies to support many of its arguments, these studies should suffice for you, George. The studies I refer to are the following:
Ben-Shakhar, G. and Dolev, K. (1996) Psychophysiological detection through the guilty knowledge technique: the effects of mental countermeasures.
Journal of Applied Psychology, 81, 273-281.
Elaad, E. and Ben-Shakhar, G. (1991) Effects of mental countermeasures on psychophysiological detection in the guilty knowledge test.
International Journal of Psychophysiology, 11, 99-108.
Honts, C.R., Raskin, D.C. and Kircher, J.C. (1987) Effects of physical countermeasures and their electromyographic detection during polygraph tests for deception.
Journal of Applied Psychology, 1, 241-247.
Now, what these studies show is that, while countermeasures
may increase false negative outcomes (guilty suspects classified as "innocents"), they have absolutely no effect on innocent examinees. (Ben-Shakhar, G. "A critical review of the control questiions test."
Handbook of Polygraph Testing. Academic Press, 2002.)
What does that last statement mean to this forum, George? It means that by providing countermeasure knowledge to your audience you are doing absolutely nothing to help the innocent except make them screw with their own heads and possibly be detected by the polygrapher. Meanwhile, you are providing the guilty with knowledge that
may help them avoid being detected altogether. When seen in that light, so much for your forum being a service to the innocent.
With regard to your comments on the CQT and the R/I tests, I don't know that the R/I technique is really making a "comeback." It never really left. The NSA uses it almost exclusively. However, I foresee the use of the DLT (directed lie test) increasing. Also, the GKT, which is based on more sound scientific principles than the CQT and has been used by Japanese law enforcement almost exclusively with excellent results, may also be incorporated with more frequency within the U.S. Finally, the BLT, an old standby, will never go away. It's high in cholesterol, true, but yum, yum, yum!
One more thing. The "challenge" which is the subject of this thread is an empty challenge. Even if the pro-polygaph community were to accept such a challenge and "prove" its own agenda, the "pro-" people wouldn't really prove anything since they couldn't effectively equate their laboratory findings to the real world. At the same time, the "anti-" crowd, which eagerly accepts any favorable laboratory study as "proof" of its own agenda, would justifiably, albeit uncharacteristically, reject such findings on the same basis. So what's the point? For those reasons, as well as such a study's prohibitive cost in dollars and time, the "challenge" is ignored.
