Hi, I'm new to the site and lately I have been quite concerned about the new job I am transferring to within the next 7 to 8 days.  I am going to be working for a MAJOR Department of Defense contractor requiring a special access security clearance.  The contract that I signed (....my life away that is hehe) specifies that a polygraph may or may not be administered, although the human resources contact said a polygraph would most likely be administered.  

On page 121 (Chapter 4) of Lies Behind the Lie Detector, it states that FBI applicants should seriously decline submitting to a polygraph because failing can adversely affect your chances of obtaining employment with other law enforcement agencies, obtaining future security clearances, etc.  

1) So if I were to submit to the polygraph and failed, would I be blacklisted as well and be unable to find employment within DOD contract opportunities again?

2) Even though I signed in agreement to the polygraph, what will happen if I decline to take the polygraph?
