Quote from: George_Maschke on Apr 19, 2015, 05:35 AMAs noted on the blog, AntiPolygraph.org has obtained and published a set of leaked Defense Intelligence Agency (DIA) "confirmed countermeasure" case files:
https://antipolygraph.org/blog/2015/04/18/leaked-documents-point-to-dias-inability-to-detect-sophisticated-polygraph-countermeasures/
These cases provide insight into the kind of activity that results in accusations of countermeasure use. Such activities are broadly: 1) anything that affects the seat pad or foot pad tracings (like using a tack in one's shoe, pressing one's toes to the floor, or pressing down on the polygraph chair's arm rests with one's arms) and 2) deep breathing.
Does DIA routinely polygraph all applicants now?
Nothing in the case files suggests any ability to detect the kinds of countermeasures outlined in The Lie Behind the Lie Detector or in Doug Williams' manual, How to Sting the Polygraph.
The DIA countermeasure case files suggest that the countermeasures being "detected" at DIA are largely those performed by individuals who haven't done their homework, and that actual spies, saboteurs, or terrorists who do understand polygraph procedure and proper countermeasures are unlikely to be caught.
Because DIA's countermeasure "detection" techniques are the same as taught to other federal agencies, the shortcomings associated with DIA's countermeasure detection efforts are likely to exist with respect to other federal agencies as well.

QuoteGeorge, where did you get this file from?
