If anyone finds a case where someone's poly showed deception and they were found innocent, be sure to post it here. :tyou:
Okay, first case that came to my mind was that of murdered little girl, Riley Fox, and her dad, Kevin Fox.If anyone finds a case where someone's poly showed deception and they were found innocent, be sure to post it here. :tyou:
As per reports, Bill Wegerle failed the poly regarding the murder of his wife. Later, it was proven conclusively that she was actually slain by BTK.

if polygraphs are so accurate, why aren't they allowed in court? Certainly if they were even as accurate as eyewitness testimony (which is notoriously unreliable), they would be allowed as evidence.
The website that is mentioned is a pro-polygraph site. I would like to see independent studies on the accuracy of polygraph testing.
Another issue is that they won't work on true sociopaths/psychopaths who have no guilt over what they have done. If they aren't emotionally heightened or stressed, they won't trip up the polygraph.
Even if I were clean as a whistle, I would never take a polygraph. Way too many variables and chances for things to go wrong.
I hate it when I read on here, "He must be guilty! He refused the polygraph!"
That's just crap.
"Researchers conducted 12 studies of the validity of field examinations, following 2, 174 field examinations, providing an average accuracy of 98%. Researchers conducted 11 studies involving the reliability of independent analyses of 1,609 sets of charts from field examinations confirmed by independent evidence, providing an average accuracy of 92%. Researchers conducted 41 studies involving the accuracy of 1,787 laboratory simulations of polygraph examinations, producing an average accuracy of 80%."

How accurate is a polygraph?
