Did you know they don't polygraph pregnant women?
I heard a fellow on NG say it's because they can get a reading on the baby's reactions somehow. Yes, that is pretty interesting!
This is just one site's opinion. There's a lot of pros and cons that can be found on the internet!
"How accurate is a polygraph?
While the polygraph technique is highly accurate, it is not infallible and errors can occur. According to the American Polygraph Association over 250 studies have been conducted on the accuracy of polygraph testing during the past 25 years. Recent research reveals that the accuracy of the new computerized polygraph system is close to 100%." <snipped>

"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%."

I have taken a polygraph, after my house was involved in a home invasion. I was the victim, treated as the perp, answered every question 100% honestly, and was told I "failed miserably". I had absolutely no knowledge, or involvement with the home invasion, was 100% a victim. This was in Brevard County Florida.
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.
I think it was useful in the Susan Smith case. Susan's test showed that her greatest level of deception was when she was asked the question; "Do you know where your children are?"Do you guys think polys are useful at all?
