The Lie Detector / Polygraph: Useful Scientific Tool or
Charlatan’s Trick? UPDATE 10/13/05


Polygraph 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.
Polygraph "testing" has no scientific basis.
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.

Tabacco initially published this Comment without an Article – a Throw Away. I had no idea so many people would be interested. I stated clearly in the Excerpt: No Article – That’s It! But 10 optimists ignored my warning and pushed the “More” anyway. So, here goes. I told you it was a con – Sorry, Maury!

CAN YOU BEAT THE POLYGRAPH?
YES
"[Polygraph screening] is completely without any theoretical foundation and has absolutely no validity...the diagnostic value of this type of testing is no more than that of astrology or tea-leaf reading."

Are you aware that truthful people can fail a lie detector / CVSA examination?
Every year thousands upon thousands of people (especially police officers) are subjected to these things. Police departments use them as a regular hiring practice for their job openings. There are many reasons that a truthful person will fail. Just a few reasons include nervousness, health problems, surprise, etc....
Polygraphy has not been shown to reliably distinguish between truth and deception in healthy individuals, there is no reason to expect that these "machines" are reliable when used on people with chronic medical conditions. As matter of fact, the American Medical Association has taken a stand against these machines and testified before Congress in support of the 1988 Employee Polygraph Protection Act. Once again, there is no way to explain why a subject--healthy or ill--may have "failed." These "tests" are simply not a reliable way to measure truthfulness.
WASHINGTON -- The use of the polygraph is not nearly as valid as some say and can easily be beaten and should never be admitted into evidence in courts of law, say psychologists from two scientific communities who were surveyed on the validity of polygraphs. This survey appears in the June issue of the American Psychological Association's (APA) Journal of Applied Psychology.
"The B.C. Civil Liberties Association believes that there is convincing evidence to suggest that the use of the lie detector is arbitrary, subjective, biased toward accusations of guilt and claims of very high validity are scientifically indefensible. However, even if one is not willing to be persuaded by evidence on these matters, one must admit, at the very least, that there is no scientific opinion whatsoever concerning the validity of the polygraph. In fact, there is extremely wide divergence over the validity itself."
These machines are not to be taken lightly. There are still several hundred thousands people every year tricked into taking one of these things. They are inaccurate and unreliable. NASA has even written articles on why these things don't work. Why trust your career or your freedom to some machine that has been proven time and time again to not work. Our staff is experienced and has taken several of these tests for open police officer positions and have yet to fail one. This technique is tried and trusted. At least give it a look. It could be the difference between a new job and your same old one you hate so much.

Synopsis of Law
The EPPA prohibits most private employers from using lie detector tests, either for pre-employment screening or during the course of employment. Employers generally may not require or request any employee or job applicant to take a lie detector test, or discharge, discipline, or discriminate against an employee or job applicant for refusing to take a test or for exercising other rights under the Act. Employers may not use or inquire about the results of a lie detector test or discharge or discriminate against an employee or job applicant on the basis of the results of a test, or for filing a complaint, or for participating in a proceeding under the Act. Subject to restrictions, the Act permits polygraph (a type of lie detector) tests to be administered to certain job applicants of security service firms (armored car, alarm, and guard) and of pharmaceutical manufacturers, distributors and dispensers. Subject to restrictions, the Act also permits polygraph testing of certain employees of private firms who are reasonably suspected of involvement in a workplace incident (theft, embezzlement, etc.) that resulted in specific economic loss or injury to the employer. Where polygraph examinations are allowed, they are subject to strict standards for the conduct of the test, including the pretest, testing and post-testing phases. An examiner must be licensed and bonded or have professional liability coverage. The Act strictly limits the disclosure of information obtained during a polygraph test.

Lie Detector Roulette
News: Everyone admits that polygraphs are unreliable. So why are government employees subjected to tests that can ruin their careers?
By Brendan I. Koerner
November/December 2002 Issue
Now, I already told you in the original non-article that this “evidence” is not admissible in a court of law. So why, you ask, did O. J. take one and allegedly fail it? Psychology! Jury influencing! Media propaganda! Take your pick. Obviously O. J. didn’t know what you now know or his guilt complex was just too strong to permit him to lie without sweating.
It basically comes down to intimidation. If the subject believes it, he or she will fail the test. If the subject is psychotic and feels innocent, in spite of having committed the crimes, he will pass. If he is naturally nervous in all pressure situations, he will fail. An accomplished liar will probably pass. So take your pick. It’s a waste of time unless your subject doesn’t know how flaky this thing is. If the subject is unaware of the truth, he or she will buy into it and admit everything once Maury Povich announces, “Reader, the lie detector test determined that was a lie!”
