Polygraph (commonly referred to as a lie detector) is a means to measure and record the number, such as blood pressure, pulse, respiration and skin conductivity of physiological indicators, and asked this question the answer is in the range of issues of faith, which lie The answer will have people from non-deceptive answers to the differences in physiological responses.
Printing industry generally rejected as pseudoscience by the scientific community. However, the polygraph as a criminal suspect or sensitive for public or private sector employment candidates some of the tools used in the trial of the country.

The printing industry's credibility among scientists. Although 90-95% polygraph validity of polygraph services advocates and 95-100% of the enterprises claimed that critics argue that, rather than a test, this method is equivalent to the inherent accuracy of unstandardizable interrogation techniques can not be established. Critics also believe that even if the estimated received high accuracy of the polygraph subjects (such as 10% to give 90% accuracy) will appear in the amount of lying, and would have been unfair to the consequences of failing the polygraph.

In 1998, the Supreme Court case, United States v. Scheffer, the majority said, there is no consensus, polygraph evidence is reliable and with other expert witnesses who testified outside the jury's knowledge of the facts of the matter, such as fingerprint analysis, ballistics, or DNA found at the crime scene, polygraph experts, another opinion can only provide the jury. In addition, 11 of 2005 Circuit Court of Appeals pointed out that the printing industry does not enjoy general acceptance from the scientific community. Charles Honts, Boise State University professor of psychology, giving innocent trial lie detector false alarm rate is high.
