To the polygraph examiners reading this: no one becomes a polygraph examiner hoping to falsely accuse the innocent. Peter Brannon, a one-time Catholic priest, must be devastated by what he did. But you need to know that no amount of training, no amount of experience, can make up for polygraphy's lack of scientific underpinnings. Understand that you are practicing a voodoo science. It's time you stopped pretending otherwise.

This is an excellent point, George.

Unfortunately, I have the feeling that when polygraph examiners hear of a verified "mistake" by a fellow examiner, they certainly just shrug and think something like, "Well, I bet the guy was lying about something."

I have had lots of people on other message boards tell me that during my three pre-employment polygraph "failures" I must have been lying about something, perhaps even something I didn't even know I was lying about, which is why I failed.  The amount of people out there who are just unable to accept the fact that it is possible to tell the truth and "fail" a polygraph is frustratingly large.
