Gordon,

Skeptic's remarks with regard to the shortcomings of "security through obscurity" have direct relevance to the issue of polygraph security screening. Even if the public at large knows little about polygraphy (just as it knows little about cryptology), it is not safe to suppose that these matters are unknown to foreign intelligence services.

You also write in part:

I haven't touched upon the ethics of teaching someone how to manipulate a forensic test.

Is it your position that the Relevant/Irrelevant polygraph technique is a "forensic test?" If so, perhaps you could provide us with other examples of forensic tests whose validity (like that of the R/I "test") is completely unsupported by any peer-reviewed research whatsoever?

Perhaps you could also tell us what the sensitivity and specificity of the R/I "test" is for the detection of deception? If you can't, then perhaps you could give us examples of other forensic tests that have unknown sensitivity and specificity?
