My last five-year security update was performed in 2005.  The field investigator from DOD not only interviewed my references and coworkers but also interviewed me.  I wanted to let the investigator know my opinion of the polygraphs for the purposes of security screening, and was informed that polygraph is indeed controversial among the field investigators.  Probably the proliferation of information about polygraph (establishment of AntiPolygraph.org, the flap at LANL and the NAS study, all occurring between 1999 and 2005) must have been a revelation to the investigators.

So there is reason for hope.
