The case files [...] suggest that the only people being "caught" trying to beat the polygraph are those using crude, unsophisticated methods that anyone who actually understood polygraph procedure and effective countermeasures [...] would ever use.
Did you mean "never use"?
Yes! Thank you.
That's precisely the official thinking about polygraph policy. Ten years ago, a senior instructor at the federal polygraph school floated the idea of criminalizing the public dissemination of information about polygraph countermeasures. I never thought it would come to pass, but it seems a considerable effort is being made.
