Polygraphy is Quackery
Scientists overwhelmingly agree that polygraph "testing" is junk science. The only "raging debate" pits people who don't yet understand that it's flimflam against the growing number who do.
Our government's stubborn reliance on this pseudoscience poses a clear and present danger: make-believe science yields make-believe security.
This non-profit, public interest website is dedicated to telling the truth about lie detectors that those with vested interests in perpetuating the polygraph don't want you to know.
The lie detector is itself based on lies...
Did you know it takes less training to give lie detector "tests" than it does to give haircuts? The longest polygraph school (run by the U.S. Government; perhaps its students are slow learners) produces newly minted polygraphers in just 14 weeks -- less than half the time it takes to graduate from a typical barber college. But while barber college graduates can cut hair, polygraph school graduates cannot detect lies.
The dirty little secret behind the polygraph is that the "test" depends on trickery, not science. The person being "tested" is not supposed to know that while the polygraph operator declares that all questions must be answered truthfully, warning that the slightest hint of deception will be detected, he secretly assumes that denials in response to certain questions -- called "control" questions -- will be less than truthful. An example of a commonly used control question is, "Did you ever lie to get out of trouble?" The polygrapher steers the examinee into a denial by warning, for example, that anyone who would do so is the same kind of person who would commit the kind of behavior that is under investigation and then lie about it. But secretly, it is assumed that everyone has lied to get out of trouble.

Executive Summary
POLYGRAPH "testing" has no scientific basis: it's entirely dependent on your ignorance and fear. Educate yourself. In this book, you will discover the trickery on which polygraph "testing" depends, and learn how to make sure you pass your polygraph "test."
Our government's reliance on unreliable polygraph "testing" is both a danger to our national security and a hazard to the reputations of law-abiding citizens whose trustworthiness is judged by this voodoo science. The Lie Behind the Lie Detector exposes polygraph waste, fraud, and abuse.
Chapter One covers the validity of polygraph "testing." Polygraphy can have no scientific validity because it is not a scientific procedure.
Chapter Two discusses polygraph policy, with special emphasis on the Aldrich H. Ames espionage case. In addition, the false positive problem in polygraph security screening is also discussed in detail.
Chapter Three exposes the trickery on which polygraph "testing" depends.
Chapter Four provides detailed instructions on how to use polygraph countermeasures to protect yourself against becoming a false positive.
Chapter Five discusses grievance procedures for those who have been falsely accused based on polygraph chart readings.
