Some famous cases that the polygraph was used. Oj Simpson civil case. Mr. Simpson took a Lie Detector test.

NEW YORK — O.J. Simpson flunked a lie detector test just after the double murders of his ex-wife Nicole Brown Simpson and her friend Ronald Goldman and even his own lawyer tried to get him to plead guilty, says one of his former closest associates.

In an interview with Barbara Walters to be shown tonight on ABC’s “20/20” news program, longtime Simpson friend Robert Kardashian said he was devastated by the results of the defense-administered test.

“I was devastated,” he said. “I didn’t know what to believe . . . O.J. said, `Every time I heard Nicole’s name, my heart was pounding, I would, I would get emotional and’ – that type of reaction.”

Trial experts said this would be the first time a key figure in the case has directly said Simpson, who was found not guilty of the double murders a year ago, had flunked the test.  True. He scored as low as possible, and the examiner tried to convince Shapiro (his lawyer) that it was “conclusive” evidence of his guilt; as a result of the failed polygraph, Shapiro began investigating a possible insanity defense.

For the record this test result was used in Oj's civil trial helped the Goldman’s win the civil case.

The JonBenet Ramsey case a 6 years old beauty pagent child thought to be killled by her parents or brother. The Ramsays took lie detector tests by 2 top examiners and passed. At the time everyone thought they were guilty but recent testing of DNA evidence has confirmed she was killed by an outside party. The case remains unsolved.

There are usually 10 questions in total that make up a test question format. Of those 6 are diagnostic and 3 or 4 are Relevant questions or the questions you are trying to resolve, dependent on the testing format itself.

Testing Procedure
The testing process can be divided into three parts. The first being what we call the pre-test interview. This is the time the facts of the case are explored and the questions to be included in the test are formulated. Once everyone is satisfied with the questions the person taking the test signs a statutory declaration giving the examiner written permission to conduct the test, this also doubles as a confidentiality agreement which nominates who can receive the test results.
The second phase is the data collection or the testing phase were the subject is tested on the previously agreed to questions. This is when the person who has agreed to be tested is connected to the Polygraph via the physiological sensors which feed the information into the data acquisition system then into the computerised polygraph screen and produces the chart data the examiner will use to numerically score to derive the result.
The third stage is the results stage this is when the examiner will work out the results based on the chart data and use of a numerical scoring system and a computerised algorithm specifically designed to offer conclusions based on polygraph data and charts. Once the evaluations are completed the result, is then first presented to person who has taken the test, and second, any other interested party agreed to via the Stat Dec at the pre test stage.

Theory and Practice
Polygraphy or psychophysiological detection of deception is based upon a scientific theory that can be tested with the methods of science. Any conscious effort at deception by a rational individual causes involuntary and uncontrollable physiological responses which include measurable reactions in blood pressure, peripheral pulse-amplitude, breathing and electrodermal response. The most commonly used techniques for the psychophysiological detection of deception are control/comparison question tests. The control question test (CQT) assesses a person’s credibility by looking for a differential reaction between two questions: the relevant and comparison questions. It has been shown that a person will develop a “psychological set” and direct their attention to the question that posses the greatest anxiety, concern or threat to his/her well being if they have decided to be dishonest in their answers.

Yes, absolutely this is a very common request for our business and we are very skilled in this area. You will also benefit from some free counseling from our examiner who is also a trained and experienced Counselor and Forensic Psychophysiologist.

There is a small arsenal of research that shows a properly conducted lie detector tests are 90 to 98 percent accurate. More recently a field study was conducted using a specific issue format known as the Quadri -track ZCT or some refer to it as the MQTZCT.

In my opinion, after reviewing a lot of literature on polygraph testing this particular testing technique is the most reliable of the numerous formats out there, if not the best.

There have been 3 field studies conducted using this testing format and all of the studies show very high accuracy rates the research can be viewed at:

The Journal of Physiology and Behaviour Mangan, D. J., Armitage, T. E., Adams, G.C. (2008a). A Field Study on the Validity of the Quadri-Track Zone Comparison Technique. Physiology and Behaviour, 95 (1-2), 17-23

The results of this study showed almost perfect conclusions with inconclusive (no opinion) results removed. This was in line with previous research conducted in 1989. The arguments against the Quadri-Track Zone Comparison Technique in Physiology & Behavior, are based largely on dated articles that examined control question polygraph techniques whose psychological test structures, physiological analyses, and scoring systems are significantly different than those of the Quadri-Track ZCT. Iacono and Verschuere et al. alleged that the Quadri-Track ZCT is biased against the innocent and can be defeated with the use of countermeasures without considering the technique’s unique “remedial inside track” that quantifies the innocent examinee’s fear of error—and the guilty examinee’s hope of error—which are factored into the overall score,thus avoiding false-positive and false-negative errors. Their objection to the use of confessions as the criterion for ground truth presumes that the polygraph examinations conducted in this field study were conducted in a vacuum. They ignored the various methods of post-test confirmation and research studies that support the use of confessions as ground truth. Verschuere et al. cited the National Research Council’s 2003 report to support their conviction that the accuracy of polygraph tests is well below perfection and errors often occur. However, they failed to mention that the accuracy range values of the seven field studies which met the National Research Council’s scientific criteria were from 0.711 to 0.999 with a median value of 0.89, and that the field study with the highest accuracy (0.999) was from a published 1989 field study on the Quadri-Track Zone Comparison Technique.
