Skeptic,

I'm sorry if I misunderstood you.  I thought you were talking about the polygraph generally.  On several occasions George has raised the issue of whether any accepted forensic test can in any way depend upon secrecy for its effectiveness.  I had that in mind when I brought up psychological tests.  I was thinking of forensic applications of tests (both psychological and polygraphic), not security screening.  The point I was intending to make is that both the CQT and many psychological tests were originally designed for use with relatively naive subjects.

I presume that the validity of both the CQT and a number of forensic psychological tests would be inversely proportional to the subject's knowledge of the tests' construction, what items belong to which scales, the scoring systems, etc., and directly proportional to the examiners' knowledgeability, experience, and skill in detecting countermeasures, access to collateral and background information, etc.

Peace,

Gordon
