Quote from: guest on Jul 30, 2004, 02:43 PMMarty, I know that poly's with the CIA, NSA do not include control questions. I know this because my friend went through a poly and he was never asked a question like "do you ever lie to your love ones during his test. Wouldn't that make it much harder to pass while lieing? Also, what is a "false negative" on a poly?

Quote from: George W. Maschke on Jul 30, 2004, 02:29 PMMany people have passed polygraphs while lying. For example, spies like Ignatz Theodor Griebl, Karel Frantisek Koecher, Larry Wu-tai Chin, Aldrich Hazen Ames, and Ana Belen Montes all passed the polygraph while lying about relevant issues. So, too, did Gary Ridgway, A.K.A. "The Green River Killer," the deadliest serial murderer in U.S. history.
