Pailryder, I worked behind the walls in a state prison polygraphing skinners -- and other SOs -- for over five years.

In response to your question about A-P advice used for nefarious motivations...

My educated guess is that hundreds, if not thousands of evil-doers in the USA alone have benefited from the information freely available on this web site.

Distressing?

Hell, yeah.

Conversely, a similar number of truthful applicants have managed to pass their polygraph "test" because the same information is available to them.

So....what does that tell you about the efficacy of the "test"?
