While the evidence gathered during a proper lie detector test is useful, it may be tainted by various factors, including the ability of the subject to purposefully deceive the machine. Remember that the device used does not have any ability to detect an actual lie. It merely can sense and record anatomical data which is typically linked to the automatic bodily responses displayed when a person is being deceptive… Polygraphs are most successful when combined or supplemented with other forms of lie detection, which may be harder to cheat…Polygraph Test AdviceIf you are considering hiring a polygraph examiner to create additional evidence for your case, make sure to follow a few simple rules. Always hire the best examiner available, with extensive experience with testing and preferably a background in psychology. Second, make sure to have the subject sign all the necessary waivers and a document stating that they are willingly submitting to the test, know the reasons for the test and are not trying to deceive the examiner. This alone can make a guilty person perform poorly on the actual exam. The more elaborate the test is, and the preparation of affidavits beforehand, the less the subject can actively concentrate on beating the accuracy of the exam…To learn more about lie detector testing, contact a licensed private investigator or a qualified polygraph examiner for detailed information.
