The interesting thing about polygraphs is that they can be an effective interrogation tool as long as the subject believes they work. (but then again so Santa Claus if the subject believes in him)
For instance the interrogator says, "the polygraph says you're hiding something from me, are you sure there isn't something you want to get off your chest."
The should however, be banned completely because the false positives are so high that we are crippling many of the agencies that rely on them. We're forcing them to drastically reduce their potential talent pool based on pseudo science.

- sukilot 12y agoIt doesn't do that, because it doesn't work at all. Regular interrogation does that
- learc83 12y agoIt does have an effect on subjects who believe it works, it's causes them to believe that the interview knows they are lying. I would expect this to select for good liars among people who believe the lie detector works.
