FAQ

The polygraph device (lie detector) is a scientific instrument strictly utilized during specific validated protocols and sequences, called the lie detector test. It can simultaneously record changes in several physiological variables (blood pressure, pulse, perspiration, and others) while the examinee is asked a series of questions pertaining to specific issue/s under investigation. The data collected and the graphic charts generated during the polygraph examination are analyzed and interpreted by an experienced polygraph examiner only.

Many scientific studies have shown over the last 100 years that if the test is administered professionally by an experienced examiner, the accuracy of the results exceeds 90%. The GPS examiner is highly experienced and certified and is a full member of the American Polygraph Association (APA).

How many questions can I ask?

All scientifically validated lie detector techniques limit a single lie detector test to the use of no more than four (4) pertinent questions per test. The limit is a professional standard, aims to ensure a reliable outcome, and has nothing to do with test length or pricing.  The pertinent questions should only address specific actions the examinee did or did not do and cannot include feelings or thoughts.
In addition to the pertinent question/s established by the client, the examiner will compile other question types with the examinee as part of the procedure. The examinee has to pass all test questions successfully. Fails One-Fails All (fails in the entire test). It is, therefore, why the examiner will help you compile the best pertinent questions to cover all of your concerns.

Polygraph examinations are commonly conducted by polygraph examiners in the private, law enforcement and government sectors in over 90 countries.

The Polygraph test procedure includes pre-test interview, test and post-test. Depending on the subject/s in question and the type of format chosen, the entire procedure usually takes between 1.5-2 hours.

GPS uses the Lafayette Instruments LX 6 computerized polygraph device, equipped with the most advanced sensors and lie detection technology available to date.

The polygraph examiner is not a medical doctor unless stated otherwise. As every type of test may increase the anxiety level of a participant, the polygraph examination is not different. The examinee should always consult with his/her physician prior to taking the test. During the Pre-Test phase, the examinee is required to fill out medical release forms in which to disclose known medical or psychological conditions. Additionally, the examinee must specify the use of any kind of drugs or narcotics (subscription or non-subscription), which he or she takes or should have taken during the week/s prior to the test date. If your health condition is stabilized, it usually should not prevent you from taking the polygraph test. Some temporary medical conditions such as the flu, dental, and other painful injuries or illnesses may require rescheduling.

From a professional standpoint, it is much better for the examinee to take the test in a neutral environment such as in the examiner’s office. Though administering the test in the examinee private environment is not advised, some unique circumstances can be considered as long as some pre-conditions are professionally met. You may discuss your concerns with the examiner during the initial consultation.

It is highly unlikely that you will be able to fool an experienced examiner who uses an advanced polygraph technology. One may find resources which offer unreliable counter-measures (CM) guidance. However, using those advices will result being detected as deceptive (DI) or purposely non cooperative (PNC).

If you intend to try and apply any type of CM, it is better to not take the test! It might even save you some money!

If the test result showed significant responses suggesting the examinee may not be telling the entire truth (DI), there is no point in taking another test. However, if the examinee chose to disclose some new information following the test, the examiner may consider administering a re-examination.

A re-examination is a totally new exam, usually with new exam fees. In most cases, re-examination involves modification of some test questions based on the new information provided. A re-examination will usually take place on a different date.
