Eric,
Addressing a few of your comments in no particular order:
1. My reference to chaos was in connection to the application process in general and not with polygraph screening in particular. I do not contest nor doubt your surprise at the notion. It is perfectly conceivable to me that the chaos introduced by polygraphy would be felt by the end-consumer seeking to hire employees and human resources personnel seeking to facilitate this process and not by oblivious polygraphers who are more or less finished with the process with the provision of any error they may have introduced into the process. This is particularly true in large agencies where these groups of people are likely administratively (if not geographically) widely separated.
2. Although I performed nuclear magnetic resonance (NMR) experiments in the world of analytical chemistry before there was such a thing as functional magnetic resonance imagining (fMRI), I have had no involvement in the latter in its various purported applications in the world of psychophysiology.
3. The dependent measure which you have confused for fMRI and which I am involved with is event related potential (ERP) measurement in general and more specifically the P300 response as it relates to the detection of concealed information. I am not involved in any sort of lie detection work. I do not see any reason to believe that any dependent measure or combination of dependent measurements will ever lead to reliable lie detection.
4. My various criticisms of lie detection began at least a decade prior to my formal and financial relationship to P300 work. I have and continue to be a proponent of concealed information testing whether it be using the channels of the standard polygraph and a GKT format or other measures (e.g., P300, fMRI or other) with other more sophisticated concealed information testing formats.
5. The application of pre-employment polygraph screening is little more than a poorly constructed fishing expedition. No technology (i.e., combination of dependent measures) that I am ever associated with will be offered as an alternative to present polygraph channels for such purposes. The application is fatally flawed--it will not work with anyone’s old or new technology. That which I am presently associated with and which you allude to will be used for two purposes (it does have other potential applications in the medical and advertising worlds) in the context that we are speaking: (1) concealed information testing regarding specifically known-to-have-occurred events (e.g., crimes) and (2) determination of group associations (e.g., Does this person have specific knowledge of training, methods, organizational hierarchy that would indicate an association with Al Qaeda, etc?).
6. I’m with you on “catching bad guys.” I presume you are with me on not wanting to catch good guys and gals in the virtual net designed for the aforementioned bad guys. I will be literally and figuratively away for much of the time between now and the new year (so not available for much back and forth discussion) but will be happy to resume at that point. Regards and happy holidays...
Fascinating stuff.
I will be considerate of your holiday time. I am aware of the differences between p300 and fmri, I made an oversight by confusing the two. I do appreciate the fact that you recognize that the GKT polygraph test is a very accurate means to knowledge detection (so to speak.) I loathe the thoughts of innocent people being falsly accused also, and to paint polygraph examiners as thoughtless, mindless predators as many in this realm often do is rediculous.
Yes, I want the bad guys caught.
I was not intentionally referring your past antipolygraph testimonies and your new career avenue in P300 Memory Detection as being chronologically overlapping. Apologies.
I do believe it is telling that in all the peripheral career choices, you pursued an up and coming concealed memory detector. Sounds like fun, and hard work pioneering such things.
Can you state here any anecdotal or empirical information regarding the ease of which to engage in countermeasures with the P300 equipment?
P.S. I no longer administer polygraph tests, so I really am objectively fascinated by P300 waveforms, and their potential.
Happy Holidays!
Eric
