Cure-E-US in C-Att-Tell,

As I have said before, I am confident I can teach people to quickly and easily produce NDI charts--so needless to say, I believe I can do it myself.  In fact, it would be very easy to produce both very good DI charts (admittedly not many real world applications) and/or NDI charts for any given set of circumstances being investigated through CQT polygraphy.  

Because I am well known within the polygraph community and specifically with regard to my views regarding polygraph countermeasures, it would be difficult for me to take such an exam without routinely being accused (in the absence of any objective and demonstrable evidence of such) of using countermeasures.  Furthermore, it would be impossible to demonstrate the limited training necessary to successfully utilize countermeasures with me serving as an (the) examinee.  And the most serious drawback to your suggested scenario is that it would be difficult to duplicate the real world setting in which a polygraph examiner is forced to decide between a true negative, a false negative (no countermeasures used), and a false negative (countermeasures applied) for any given set of NDI charts.  This requires a scenario such as "the challenge" which entails having the participation (as examinees) of multiple people, none of whom is more likely (than other participants) to use or to have been trained in the use of countermeasures, some who will be programmed guilty (the balance being innocent), and some of whom will be taught and will use countermeasures (the balance not).  

It is also necessary for purposes of maintaining external validity that examiners not be aware what percentage of examinees are guilty/innocent as well as the percentage who will utilize countermeasures.  For these various reasons I believe your scenario would be unlikely to obtain results for much of what the challenge was designed to investigate and be directly confounded in several respects through my participation as an examinee.   However, thank you very much for your time and thoughts...   Regards,

Drew Richardson

Your suggestion is not, in my opinion, a reasonable alternative. It is incumbent upon those who lay claim to scientific validity, accuracy, and reliability to prove their (to date) gratuitous assertions. Until such time, I will continue to hold the opinion that polygraphy as it is largely practiced today is less than worthless- it is a moral travesty foisted upon the American public by strutting martinets like batman, polycop, pdd fed, et. al.
