Antipolygraph.org is an excellent site for information about how evil the uses of the polygraph often are and how to overcome these twisted attempts of manipulation.  And.......The Lie Behind the Lie Detector is simply AWESOME!  I failed my last (mandatory, but I won't get into it) polygraph "test", and I was totally honest.  And I downloaded and printed out the free copy of this publication and am studying it and highlighting the critical data.  I WILL pass my next examination (I really need to).  Thanks to the people responsible for Antipolygraph.org and The Lie Behind the Lie Detector
