You can be the best judge of character in the world, but when you’re speaking with a practiced liar who is motivated to deceive you, you can look them straight in the eye and never have a clue that they’re not telling the truth. That is until it’s too late. Don’t take chances on relying solely on your instincts. At American Eagle Investigations in NYC, we offer a full range of lie detector testing services that we can administer in our office.
The Lie Detector Test examination begins with a pre-test interview to elicit information that will later be used to formulate “control questions, relevant questions, and irrelevant questions.” This initial interview is where the examiner must be extremely sensitive to the examinee’s background, culture and education, in order to understand the logical reasoning of the subject.
The examiner will then explain how the polygraph instrument works, show the examinee actual polygraph chart tracings, identify psychophysiological responses on the chart tracings, and emphasize the importance of answering the questions truthfully.
With the examinee’s full understanding of the questions to be used and the agreement by both the examinee and examiner to use the relevant questions, the polygraph examination begins. Upon completion of the test, the chart tracings are marked and scored, and shown to the examinee with a full explanation of the results. A report containing the results with the examiner’s opinion is also given to the examinee.
As experienced private investigators, we can also offer advice as we have dealt with our fair share of liars as well.
A polygraph, also known as a lie detector, and psychophysiological detection of deception (PDD) examination, is an instrument that measures and records several physiological functions, such as, blood pressure, pulse, respiration, and skin conductivity. The subject is asked and answers a series of questions, in the belief that deceptive answers will produce psychophysiological responses that can be differentiated from those associated with non-deceptive answers.
It is important to note that the Employee Polygraph Protection Act of 1988 prevents employers from using the lie detector test for pre-employment screening or during employment; however, there are certain exceptions. In the United States, the State of New Mexico admits polygraph testing before juries in certain circumstances. In many other states, polygraph examiners are permitted to testify before judges in various cases, such as the revocation of probation. Many law enforcement agencies and intelligence agencies in the United States utilize polygraph. Polygraph testimony has been admitted by stipulation in approximately 19 states and in the Federal Court, although it is subject to the discretion of the trial judge.
While extensively used in post-conviction sex offender cases, no one can be forced to take a polygraph examination. In 1998, the U.S. Supreme Court left it up to individual jurisdictions whether polygraph results could be used as evidence in court cases. In the case of a spying charge, a polygraph is more often used as a deterrent to espionage rather than detection. Failing a polygraph test could cause revocation of security clearance. However, it remains inadmissible evidence in most federal courts and military courts-martial.
In Afghanistan, the U.S. Department of Defense uses a Preliminary Credibility Assessment Screening System, or PCASS, which gathers less physiological information than a polygraph and uses an algorithm – not the judgment of a polygraph examiner – to determine whether it believes the person is being deceptive or not. Polygraph testing is used in many states, as well as the U.S. Federal appeals courts, for sexual offenders on probation or parole, and often during the rehabilitation of convicted offenders.
