It's easy enough to beat a polygraph. One just needs to understand the trickery on which the "test" actually depends. See the AntiPolygraph.org homepage for a "Reader's Digest" version.

Thx. I agree that it should be easy to “beat” the thing. Even assuming the operator is competent simply upsetting the Control Questions will throw the results way off. I like the idea of biting your tongue when the control question is asked. Saves on buying some exotic drug to do the same thing!
