	anyone... I was under the misconception that GKTs were the only 'test' used in criminal investigations. Is the PLCQT used in criminal case type tests? ( It seems like it was used in the Molly Bish Case) Are specific incident and GKT the same?

Are specific incident and GKT the same? Yes then No. Nearly all polygraph tests in the USA are of the PLCQT flavor. GKT's can be used for specific incidence tests but rarely are unlike in Japan where the reverse is true. Japan, having started widespread polygraph forensic use later than the USA, trained it's examiners on GKT techniques, as they were more grounded in scientific theory and can be designed to reduce false positives to a fairly low level assuming sufficient test points. The problem with GKT's is they are not applicable to screening by their nature. -Marty

	suethem, An additional problem in using the GKT is the media. So much information is given to the public that it becomes difficult to properly formulate the needed questions. And if the LE agencies started to use "dis-information" to protect the details of crimes they would then be ostracized by that same media.

	All... So when polygraphers say that they only do 'criminal investigative' polys, they are still using the PLCQT format- the same format that has been found to be invalid. Bad science and tricks- not much to brag about! No wonder they hate this site.

	suethem, You are correct. It makes no difference what the reason is for the PLCQT test, it's still flawed. The Molly Bish case with those 11 people failing is a classic example. For the benefit of the polygraphers on this board, I will point out that we don't know for a fact that the PLCQT was used, so I'm "speculating" in that respect. But the odds are pretty strong that it was used.
