Apparently only Easterners and Psychopaths are able to lie on the polygraph and pass.
Polygraphs are TERRIBLE tests. They have a sensitivity of 80-85% and specificity of about 80%.

Lie Detector accuracy:
Significance & Practical Application
Polygraph testing has generated considerable scientific and public controversy. Most psychologists and other scientists agree that there is little basis for the validity of polygraph tests. Courts, including the United States Supreme Court (cf. U.S. v. Scheffer, 1998 in which Dr.'s Saxe's research on polygraph fallibility was cited), have repeatedly rejected the use of polygraph evidence because of its inherent unreliability. Nevertheless, polygraph testing continues to be used in non-judicial settings, often to screen personnel, but sometimes to try to assess the veracity of suspects and witnesses, and to monitor criminal offenders on probation. Polygraph tests are also sometimes used by individuals seeking to convince others of their innocence and, in a narrow range of circumstances, by private agencies and corporations.
The development of currently used "lie detection" technologies has been based on ideas about physiological functioning but has, for the most part, been independent of systematic psychological research. Early theorists believed that deception required effort and, thus, could be assessed by monitoring physiological changes. But such propositions have not been proven and basic research remains limited on the nature of deceptiveness. Efforts to develop actual tests have always outpaced theory-based basic research. Without a better theoretical understanding of the mechanisms by which deception functions, however, development of a lie detection technology seems highly problematic.
For now, although the idea of a lie detector may be comforting, the most practical advice is to remain skeptical about any conclusion wrung from a polygraph.

I hear this often but all of our givernment agencies continue to rely on them. I know the CIA has made some massive mistakes over the years but they are still competent in many areas and they use the polygraph on all Americans and most foreigners when they want to know the truth. Sometimes those who use the product know more thn those who speculate about it. Bodybuilders throughout the 70s claimed that you should eat lots of fat and protein and no carbs in order to get lean and every dietician in the world said they were crazy. They knew it worked because they used it. I believe it is the same with the polygraph.
