Frequently Asked Questions about Polygraph Examinations (Lie Detector Tests)

  • How much does an expert polygraph examination cost? Open or Close

    Fees vary depending on the type of exam and location where it is administered. Psychophysiological Detection of Deception (also referred to as a credibility assessment) via the polygraph is a technical skill requiring extensive training and specialized digital instrumentation. Polygraph examiners who have been qualified as an "expert" by the courts will likely have higher fees than inexperienced examiners. Experts also attend continuing education classes annually to stay professionally current. Never retain a self-taught operator. They are not recognized by any polygraph licensing board or legitimate polygraph association.

  • How many questions can be asked concerning an issue on the exam? Open or Close

    Validated polygraph techniques concentrate on a single or specific issue (e.g. infidelity, robbery, murder) and can contain up to three questions relating to the issue to be examined. Other questions are asked on the exam which do not relate to the issue directly, such as, "Are we in the United States"? The purpose for all examination questions will be explained in detail during the polygraph pretest interview.

  • Can someone beat the test? Open or Close

    Anyone can find information on the internet on how someone might attempt to defeat the polygraph in an effort to try and appear truthful when they are in fact being deceptive. Some websites will even sell these ineffective methods to unscrupulous examinees who are desperate to hide the truth. Expert polygraph examiners have been trained to identify these methods. Furthermore, modern computerized polygraph instrumentation assists the examiner with advanced software and hardware designed to expose attempts to defeat the polygraph.

  • How long will the examination take? Open or Close

    Expect your polygraph examination appointment to take approximately two to three hours. Much of that time is spent discussing the issues associated with your exam and explaining the polygraph process. The actual in-test phase where the sensors are attached to the examinee and questions are asked will last about 20 minutes and is at the end of the polygraph process. A minimum of three charts will be collected for evaluation with a short break between charts.

  • If I am nervous will that cause me to fail the test? Open or Close

    Everyone who submits to a polygraph examination is expected to be nervous to some degree. This is normal and should not affect your ability to complete the examination as long as you can sit still for short periods of time and follow the examiner's instructions during the test.

  • Are surprise or trick questions asked? Open or Close

    All questions asked during your examination will be thoroughly reviewed with you before the test begins. No surprise questions are ever asked in a properly administered polygraph examination.

  • Will I experience any physical discomfort during the exam? Open or Close

    You should not experience any physical discomfort during the examination. The blood pressure cuff of course will need to be inflated when the charts are collected. If you have ever had your blood pressure checked, then you have experienced this sensation before. The blood pressure cuff is the sensor which collects changes in cardiovascular activity.

  • Can other adults accompany me to the appointment? Open or Close

    If you are taking an exam to reassure another adult of your honesty, that person may accompany you to your appointment at your option. However, they will not be allowed to sit in on the pre-test interview or examination. In most cases the examiner can meet with them prior to the exam to ensure the issues to be examined are properly identified. They can also be provided with the results after the examination with the examinee's written permission.

  • What if I am sick? Open or Close

    If you are feeling ill on the day of your appointment it is recommended that you reschedule. You will not be tested if you are ill or contagious.

  • What can I do to prepare myself for the polygraph? Open or Close

  • What should I wear? Open or Close

    Dress comfortably but appropriately. Business casual attire is recommended. All polygraph sensors are applied over your clothing. Bulky sweaters and sweatshirts are not recommended as they interfere with sensor placement.

  • What do I need to bring to the appointment? Open or Close

    Please bring your driver's license or another form of government issued identification bearing your photograph.

  • Legal Community - Attorney / Client Polygraph Examinations Open or Close

    Polygraph is used extensively by attorneys who wish to provide the best possible defense for their clients. Most attorneys will submit their own clients to the exam, while others will use the polygraph to verify statements made by witnesses and other parties to litigation. During a credibility assessment polygraph examination, an expert examiner can provide evidence in connection with any type of criminal or civil matter. Donald Imbordino has a great deal of experience working with attorneys, both in private and government practice, and has aided hundreds of clients in preparing defenses that would otherwise have been unavailable to them. With the recent establishment of polygraph standards by ASTM, polygraph has gained great strides in credibility with the scientific community. These standards, approved by a combined body of experts through research, now provide a template for the increased acceptability of polygraph results

    Polygraph is not per-se inadmissible in court proceedings. Admissibility standards are different in each jurisdiction. Some jurisdictions allow polygraph evidence, either stipulated or un-stipulated, some prohibit polygraph evidence altogether, and many others allow the judge to decide admissibility on a case-by-case basis. The Daubert case is presently the standard for the admission of scientific evidence, which includes polygraph. In reality, most polygraph results are used outside of the courtroom in pre-trial negotiations, plea bargaining, sentence recommendations, and witness verification or impeachment.
