Please heed the advice if you're going to take a polygraph. Believe it or not, more and more polygraph examiners can in fact catch you trying countermeasures. It's not worth the risk.

Get real. No polygraph operator has ever demonstrated the ability to detect the kinds of countermeasures outlined in The Lie Behind the Lie Detector, and Dr. Drew Richardson's countermeasure challenge has now gone a decade without takers.

Anyone facing polygraph "testing" is well advised to do that which is possible to protect themselves against this inherently unreliable, fraudulent procedure.
