  1. Polygraphs are shit and this is slightly better by Henry+V+.009 · · Score: 3, Informative

    It's already more accurate than polygraphs. The dirty little secret about that, of course, is that a polygraph machine needs to be 'interpreted.' Polygraph operators are more or less dowsing for the truth. Remember all those keyboards back in the 80's that let the autistic comminicate with the rest of the world? Same kind of thing.

    If it turns out to work, it will be banned for use on TV during politicians' speeches. (The first amendment will be found not to apply.)

    Expect to see software that can edit out the facial gestures, in real time. Politicians will only release footage that has been filtered by it in their own offices.

    Software that detects that filtering will be banned.

      You are very correct - this is the definitive site on polygraphs. The most important point for /.ers to understand is that a polygraph "test" is really an interrogation. The examiner is always less interested in what the machine "says" than he is in the things he can get you to admit. The typical polygraph session is a highly scripted interview that is designed to convince you that the machine is infallible. The most important points of the polygraph session are those points where the examiner tries to get you to volunteer information that can be used against you later. There is an excellent book at the site called "The Lie Behind the Lie Detector." It's in PDF form.
