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).
