Can We Trust Polygraphs?
Among the misinformation circulating surrounding the Mary McCarthy affair is the assumption that she "flunked" the polygraph. It is not clear whether she failed or not. The only thing that all parties seem to agree on is that she admitted to unauthorized contact with at least reporter.
Can we trust a polygraph? Most of my friends in the intel community believe it only works against folks who have a conscience and a strongly developed sense of right and wrong. Important to remember that the traitor, Aldrich Ames, passed the polygraph even though he had sold his soul to the Soviets.
I received the following from George W. Maschke. I recommend it to you.
Dear Mr. Johnson
I've enjoyed reading your insightful commentaries on intelligence matters, including most recently the CIA's termination of Mary McCarthy. I'd like to share with you some thoughts on the CIA's use of polygraphs in its hunt for those engaged in unauthorized truthtelling. The Agency has long relied on the polygraph as a tool of coercion and control, but those contemplating blowing the whistle on illegal activity should not fear it, for reasons that I will explain below, and that I hope you may be able to pass along to those who may have a need to know.
