Almost as bad as the Polygraph examiner on "Texas Justice". The Judge does say he can choose to not consider the 'evidence' of the polygraph, but I can't think in one instance where he ruled against it -- except in cases where the Law prevailed and it didn't matter if they "lied" or not.
One particular quote from the Polygraph examiner, I find very, very funny - when asked about how sure he was on a percentage scale from 0-100%
The answer? 110%
....lol.. great scientific answer there.... Perhaps he also used his remote viewing machine and saw them do what they said they didn't... at a 10% accuracy rate??? err..??
Though, Polygraph does seem 'useful' in many applications. Especially in ones where those being tested have a belief that it works exactly as perscribed. For those, you can get a confession. In the instance of police work, this could be invaluable.
The real harm comes into play for those who believe it to be real, and produce a false-positive. Or for those who know it to be fake, and produce a false-negative. Or those who know it to be malarky and do not opt to take it, and are seen as those with 'something to hide'.
That's an awfully lot of "OR"s, but if you were a police officer, why not ask? Perhaps you will get a confession either before, during or after a test - regardless of 'false-positives'.
The same as if palm reading was commonly beleived to be able to detect guilt or innocence.... Honestly, even as a skeptic and if I knew it to be 'bogus', I'd probably still ask and see if I got a confession before or after it. .... If I was a police officer.... The result wouldn't matter much, more how they reacted to it. If they just denied it, well... oh well, but if they said OK OK I did it... Well...
All that said, I disagree with Dr.Phil (and many others) referring to it as "very scientific" and the like. However, on the other hand, I also hold no problems with people using it trying to illicit a confession.... It's really pretty understandable. The problem with that comes with 'the media' and that so-and-so 'failed' their test - and the people on Jury (or those judging) have belief in it... :/
.. On that note - and I'm just talking out of my ass, I don't really know for sure -- isn't the results totally inadmissable into criminal court? (ie: Jury/Judge never even hears it?) Again, not sure in the least, but isn't that the case?...... And that they're really fishing for confession?
I mean it seems to me it's pretty obvious it's not "science" or "exact" or "possible to know". If it was, How about we do the following: Interview every single person in prison with a lie detector and say "DID YOU DO IT"? YES OR NO???
The ones who pass go free! yay! I think even the average person knows, at least, that it's 'unreliable'
