I recently took a pre-employment polygraph test for a local law enforcement agency.  I was found deceptive on certain questions.  The paleographer told me at the beginning of the session that if I were deceptive I would fail.  There was no second chances or anything.  However, I have been rescheduled for another test because I was deceptive.  I have also had a high ranking individual involved in a totally different section of the agency tell me to just come out and tell all.  This individual sat there and related to me about the similar branch of military we were in, similar problems we had, and was just my buddy for the conversation.  Now in "the lie behind the lie detector" this seems to fit (as far as the trying to get a confession) in except the part with the individual not involved with the test at all.  

And any info I volunteer on the pre test questions is the same as a confession, correct?
