	Polygraph - Wikipedia, the free encyclopedia
		A polygraph (informally referred to as a "lie detector") is a device which measures and records several physiological variables such as blood pressure, heart rate, respiration and skin conductivity while a series of questions are being asked, in an attempt to detect lies.
		Then a "stim test" is often conducted: the testee is asked to deliberately lie and then the tester reports that he was able to detect this lie.
		Polygraph tests have also been criticized for failing to trap known spies such as Aldrich Ames, who passed three polygraph tests while spying for the Russian government.

	Scientific Validity of Polygraph Testing: A Research Review and Evaluation (Chapter 2)
		Polygraph examiners typically conduct what is known as a “stimulation"or “stim" test, designed to further convince subjects of the accuracy of the polygraph examination.
		The majority of uses of polygraph testing appear to be on behalf of private employers, the next greatest number are in the context of local criminal justice investigations, and the remainder are done by the Federal Government.
		Polygraph testing is employed for a variety of uses, ranging from ascertaining the guilt of a criminal suspect to assessing the honesty of a prospective employee.

	Howstuffworks "How Lie Detectors Work"
		A polygraph instrument is basically a combination of medical devices that are used to monitor changes occurring in the body.
		Polygraph exams are most often associated with criminal investigations, but there are other instances in which they are used.
		Polygraph examinations are designed to look for significant involuntary responses going on in a person's body when that person is subjected to stress, such as the stress associated with deception.

		While the polygraph technique is not infallible, research clearly indicates that when administered by a competent examiner, the polygraph test is one of the most accurate means available to determine truth and deception.
		Approximately 25% of the persons tested are disqualified from police employment based on the information developed during polygraph testing which, by the way, is used both to verify information provided in an application form and to develop information that cannot be gotten by other means.
		Polygraph errors may be caused by the examiner's failure to properly prepare the examinee for the examination, or by a misreading of the physiological data on the polygraph charts.

	Worldwide Lie Detector Tests - Polygraph Examinations

	Polygraph Test!
		It appears that in polygraph testing, laboratory results are inferior in accuracy to field tests.
		As one would expect, the reliability of the test is better than the validity because testers tend to have prior knowledge of test outcome and wish to verify each other.
		The polygraph device itself, which has essentially been unchanged since the 1930s, transmits physical evidence that is subject to many physiological idiosyncracies of the subject and test environment.

	Polygraph Testing
		The polygraph examination must be conducted by a polygrapher trained specifically in the use of the polygraph for the monitoring of sex offenders, where available, and at the expense of the sex offender.
		After reiviewing the available data and studies on polygraph testing, the panel concluded: "Almost a century of research in scientific psychology and physiology provides little basis for the expectation that a polygraph test could have extremely high accuracy." Further, there was little hope for advancing polygraph testing.
		Others have found that polygraph tests assess truthfulness significantly less accurately – that scientific field studies suggest the accuracy rate of the "control question technique" polygraph is "little better than could be obtained by the toss of a coin," that is, 50 percent.

	Who's the liar? Brain MRI stands up to polygraph test
		Traditional polygraph tests to determine whether someone is lying may take a back seat to functional magnetic resonance imaging (fMRI), according to a study appearing in the February issue of Radiology.
		Polygraph test results correlated well with actual events when subjects were asked to lie (92 percent accuracy); however, the results were not as conclusive when subjects were asked to tell the truth (70 percent accuracy).
		Since the polygraph has not been embraced as a fully credible means of lie detection, the authors hope to provide a more accurate means of determining whether or not someone is telling the truth.

		Research reveals that polygraph tests are generally accepted in the scientific community as evidenced by the volume of publications in peer-reviewed scientific journals and by surveys of scientists.
		All effects of polygraph testimony were eliminated by the introduction of negative testimony by an opposing witness who testified that polygraph tests were only 80% accurate and that the results of polygraph tests should be viewed with skepticism.
		Honts and Perry, although critical of the general level of training for polygraph examiners, note that the Department of Defense Polygraph Institute is "generally considered to be the best training facility for polygraph examiners."

		A polygraph is a machine in which the multiple ("poly") signals from the sensors are recorded on a single strip of moving paper ("graph").
		When the polygraph test starts, the questioner asks three or four simple questions to establish the norms for the person's signals.
		Both during and after the test, a polygraph examiner can look at the graphs and can see whether the vital signs changed significantly on any of the questions.

		This may because polygraph tests are known to be unreliable, or it may be because what little benefit may be derived from using the polygraph is far outweighed by the potential for significant abuse by the police.
		The American Civil Liberties Union strongly supported the passage of the Employee Polygraph Protection Act of 1988 (EPPA) which outlaws the use of the polygraph "for the purpose of rendering a diagnostic opinion regarding the honesty or dishonesty of an individual."

		No, the polygraph results are based on an assumption called the "control question." This is where the examiner tries to establish a baseline for a known lie.
		Even the best polygraph examiners are not 100% accurate, and to make a definitive decision on a polygraph alone, not corroborated by a confession or a conclusive investigation, is slander and reckless.
		If they administer the polygraph, and it is in their favor (which most likely will be the case since they know the outcome of the test prior to it being administered), they want the results available in court.
