Again, based on what you've said here about your situation, I think it is highly unwise for you to submit to a second polygraph interrogation. Was your first polygraph interrogation a "stipulated" one? That is, did your public defender agree that the polygrapher's report would be admissible as evidence in court? If so, your public defender has done a poor job defending your interests, and you need a new lawyer.
Your polygrapher told your public defender that "if the control questions wouldn't have turned out the way they did then he would have concluded deception for the relevant questions." This means that your polygrapher thinks you used countermeasures, and he also thinks you answered the relevant questions deceptively, even though he scored your charts as "inconclusive."
Will your second polygrapher have the first polygrapher's report? If your polygraph interrogations are being conducted by a governmental agency, you can be sure of it. The first polygrapher's suspicion that you were deceptive and that you employed countermeasures is highly prejudicial. I think it is quite possible that given the first polygrapher's report, your second polygrapher will not give you a "pass" regardless of your polygraph charts.
Although I think it would be foolhardy for you to submit to a second polygraph interrogation, let me nonetheless address your questions.
With regard to polygraph counter-countermeasures:
- A common one is to use a strain gauge to detect shifting of weight such as would occur if a subject were to use the tack-in-the-shoe countermeasure or to press his/her toes to the floor. You'll find illustrations of two common strain gauges in the message thread "Question concerning counter-countermeasures" on this bulletin board:
http://www.antipolygraph.org/cgi-bin/forums/YaBB.pl?board=Proc&action=display&nu...
If one were to flex other muscle groups while using the "anal pucker" technique, the strain gauge might sense a shift in weight. Anyone employing countermeasures who is concerned about a strain gauge would be best off employing other countermeasures instead. - A simple counter-countermeasure for the tack-in-the-shoe technique is to instruct the subject to remove his/her shoes.
- Some people think that applying antiperspirant to one's fingertips is a good countermeasure. It isn't. But nonetheless, polygraphers have a simple counter-countermeasure for it: make the subject wash his/her hands. Some polygraphers keep a supply of alcohol wipes with them for this purpose.
- Another counter-countermeasure, described in The Lie Behind the Lie Detector, is for the polygrapher to let the polygraph instrument continue recording physiological data for a minute or so after the last question has been asked. If the subject had been deliberately maintaining a baseline breathing pattern, any change in breathing after the last question has been asked may be taken as evidence that the subject employed countermeasures. Thus, it is important that the baseline breathing pattern be maintained until the pneumo tubes are removed from around one's chest and abdomen.
With regard to artificially creating reaction on the galvanic skin response (GSR) channel, Jimmy's suggestions coincide with my general understanding, though I don't have much specific information on this. In an article published in the American Polygraph Association quarterly,
Polygraph, polygraph charts for a subject who admitted having employed countermeasures is provided. The subject, who had studied Doug Williams'
"How to Sting the Polygraph" told the polygrapher he had employed the "anal pucker" in addition to biting his tongue when answering one of the control questions. The polygraph charts show strong reactions in the GSR channel to the "control" question on which the subject employed these countermeasures.
I would point out one possible misunderstanding that could arise from Jimmy's second point of advice about breathing:
Quote: Ensure that there is a gentle transition from inhale to exhale and exhale to inhale, each time. A good way to do this is to pause, holding your breath for like 1/2 a second after each inhale and each exhale (breathe in, slight pause, breathe out, slight pause).
I think a better way to put it might be that one's baseline breathing pattern should be "well-rounded." As Jimmy stated, there should be a smooth transition between inhalation and exhalation. If we were to compare it to driving a car, it would like the so-called "California stop" where a driver slows down for a stop sign but never comes to a complete halt such that the vehicle rolls forward and back on its suspension. What one wants to avoid a jagged baseline breathing pattern (such as would occur with panting). One wouldn't want to inhale, suddenly stop, hold it for half a second, and then suddenly exhale.
