Breeze,
You write:
Quote:When a applicant attempts countermeasures, and 2 have with my agency in the past 6 tests, are confronted with this accusation does'nt this mean detection has taken place?
No, it doesn't, because there is no known valid methodology for countermeasure detection. All that has happened in your example is that you have made an unscientific inference (a guess) that the subject has attempted countermeasures. This is so even if the polygraph operator "is reacting to specific [perceived] clues as contained in the charts."
Similarly, when a person "fails" a CQT polygraph examination, deception has not been "detected" because
CQT polygraphy has no scientific basis. Unless confirmed by a corroborated confession, the polygrapher's conclusion (based on polygraph test data analysis) that a subject was deceptive is merely a guess.
Quote:I think I spoke of the GKT test administered previously, that showed conclusively that not only had the applicant used information that only someone who had logged on to this site would know, but such applicants had much to hide beyond the stated fear of a false positive.
Although a subject might make admissions to such, a GKT itself cannot "show conclusively" that a test subject actually
used information that only someone who visited AntiPolygraph.org would know. It can only show that a person is likely to have knowledge of such information.
Note that in constructing a GKT, it is important that the person stating the choices for each question be ignorant as to which ones are the "correct" ones. Otherwise, it is possible that the questioner's demeanor or tone of voice might provide unintended clues as to which items are the "correct" ones, resulting in reactions to them from those who in fact have no knowledge of them. David Lykken explains this in
The Body on the Stairs: A Pedagogical Detective Story (Chapter 21 of the 1st edition of
A Tremor in the Blood: Uses and Abuses of the Lie Detector). For the GKT you have suggested, it would not be proper for you, or anyone else who is familiar with AntiPolygraph.org, to speak the items to be used in the test. Instead, you might make a tape recording as someone who is unfamiliar with AntiPolygraph.org -- and with polygraph matters in general -- reads the items in a monotone at appropriate intervals, and then "test the test" by administering it to people known to have visited AntiPolygraph.org and on people unlikely to have ever done so.
Did you follow these procedures before you started administering your "countermeasures GKT?"
By the way, is not your resorting to a GKT a tacit admission that you know you don't actually have any reliable methodology of countermeasure detection?
Is mere knowledge of polygraph procedure, or having visited AntiPolygraph.org, to be made a ground for disqualifying an applicant for life? If not, then how is your agency going to deal with applicants who adopt the "complete honesty" approach and admit up front that they know "the lie behind the lie detector?"
