Eastwood, my friend, I would not have found this site much less researched polygraph testing if not for the mistreatment I received in an employment screening exam which ultimately led to a false positive which led to a rejection letter.  This is a position which I am more than minimally qualified that slipped away because of reliance on a test whose foundation is built upon sand.  Did that make me angry, hell yes it did.  You mention cooperating and being truthful which is great advice.  It didn't work for me in the aforementioned exam.  So much as you feel the information here is garbage by that standard your advice is garbage as well.  The polygraph unfortunately has cause the applicant pool to become very shallow in many areas.  People who are qualified in every way (experience, lifestyle, criminal history, etc.) are being turned away from employment for one reason - polygraph testing.  Maybe you would be a bit more comfortable at the polygraphplace board where your anti-antipolygraph pep-rally would be readily accepted.  Your "get a life dudes" attitude speaks volumes of your 2 dimensional character.

Eastwood, if you believe that I have some swampland in Kansas for sale, cheap.

Even the most innocent people get false positives.  Reject someone from employment because they are simply nervous and their vital signs show it, and that is supposed to be the basis for determining if someone is lying?  Polygraphy is a joke.
