Leaked Documents Confirm Polygraph Operators Can't Detect Countermeasures (antipolygraph.org)

George Maschke writes: AntiPolygraph.org has published a document (14 MB PDF) on polygraph countermeasures that is allegedly derived from classified information. The document suggests techniques that polygraph operators might use in an attempt to detect efforts to beat the polygraph, but fails to offer any coherent strategy for detecting sophisticated countermeasures such as those outlined in AntiPolygraph.org's The Lie Behind the Lie Detector (1 MB PDF) or Doug Williams' How to Sting the Polygraph. Ominously, the leaked document avers that an examinee's stated lack of belief in polygraphy is a marker of deception. AntiPolygraph.org has also published an older U.S. Air Force Office of Special Investigations polygraph countermeasure handbook (3.2 MB PDF) that similarly offers no methodology for detecting sophisticated countermeasures (such as any actual spy, saboteur, or terrorist might be expected to use).

I thought we all knew those things where BS...

Really, there is zero scientific processes behind "lie detectors". They are intended as an intimidation tool to coerce a confession, nothing more. There's a reason they are not admissible as evidence.
