Antipolygraph.org is a site devoted to debunking the idea that polygraphs can actually detect lies.
On this website, you will learn that polygraph “testing” is:
* Theoretically unsound and is not a valid diagnostic technique.
* Entirely dependent on the polygrapher lying to and deceiving the examinee.* Biased against the truthful, resulting in many honest and law-abiding people being falsely accused each year.
* Easily beaten. The common notion that only sociopaths can beat the lie detector is nothing more than a myth. In fact, simple-to-learn techniques enable anyone to beat polygraph “tests.” A full explanation of how to perform these techniques is provided in chapter four of The Lie Behind the Lie Detector.
