Client FAQs

FAQs icon
Why should I believe the polygraph?
When a subject lies to an examiners question on the polygraph; that false answer stimulates a fear of detection to the deception. That fear of detection to the deception stimulates a variety of physiological responses in the subject’s body. These physiological responses are recorded on the computer chart and subsequently analysed to determine truthful, deceptive or inconclusive. 

A deceptive person may say one thing but their physiological responses will say another. These physiological responses are autonomous and cannot be controlled. In essence, the person’s physiology responses have a voice of their own and speak the truth.

How long does it take to get an appointment?

Is it compulsory to have a polygraph test done?
No. No one can be forced to undergo a polygraph test. The tests are totally voluntary.
What kind of questions can be asked?
The polygraph test questions will vary according to the case issue but all questions are specific and pertinent to the issue to be resolved. Questions only require a “yes” or “no” answer and with no explanation or qualification. Please see the services page for examples.
Are there any surprise questions?
No. The examiner will discuss and review all questions to be asked in the test with the examinee. There are no trick or surprise questions.
Who makes up the test questions?
The examiner will formulate the questions and review all the questions with the examinee prior to the test.
Can I be in the room during someone else's exam?
No. In order to preserve a sterile environment, no one other than the examiner and examinee can be in the examination room during the procedure. Polygraph is a diagnostic procedure which can be adversely affected by distractions.
Will the test be recorded?
Yes the test is recorded on video and audio. This is only for the professional benefit of the examiner and is to protect both parties by ensuring the process is conducted in accordance with professional standards and to assist the examiner in subsequent chart analysis.
What is the approximate time involved?
Polygraph examiners are highly trained professionals who provide a specialised service. This service requires the examiner to purchase expensive equipment and pursue continuing education in order to maintain a high degree of proficiency. The process of asking "just one question" in a series of tests could take hours, due to the diagnostic process involved, so a single examination often takes an examiner an entire working day even though time with the examinee might only be  1.5 hours. In most cases the polygraph is performed because there simply is no other reasonable way to get the desired information such as when no evidence exists.

In a fidelity case a person might spend thousands of dollars on surveillance while the same information could be obtained for a fraction of the time and price with polygraph - the result is a saving of thousands of dollars.
Why do prices vary so much depending on where you take the test?
Like anything else, the price of a polygraph test is market driven. Some exams may be as low as $500 while others it is $850. It also depends on the type of examination, issues to be resolved, and the complexity of case and travel costs associated with your location.
What if I can't get to your office?
We will travel to your location, home or office for an additional fee. Be sure to have adequate facilities available. This includes a quiet private room for testing, free from clutter and distractions, with a table or desk and two chairs - one chair with fixed back and no wheels.
Can someone under age 16 take a polygraph?
Yes, but we must have written consent of a parent or guardian. However, we will not test anyone under 12 years of age unless in extraordinary circumstances.
What do I get for my money?
You will receive a polygraph examination administered by a trained and experienced polygraph expert at the location you selected. Once the examination has been completed, you are entitled to a written report of the examiner’s findings. The examination results can take up to a week in some cases.
How does the test process work?
  • We receive and review the facts surrounding the case
  • The examiner explains the test process to the subject
  • The examiner conducts an extensive pre-test interview with the subject regarding the case
  • The examiner designs the specific test questions and reads and reviews each question to the subject to make sure each one is easily understood
  • The test subject is attached to the polygraph instrument and given additional instructions
  • The questions are read to the subject several times while they are attached to the polygraph sensors
  • After all charts have been run, the examiner analyses the charts and develops a numerical score for the test. This score results in a conclusion of truthful, deceptive or inconclusive.
NOTE: The average polygraph exam takes from 1½ to 3 hours to complete.

How should someone prepare for taking a polygraph?
A person should be well-rested and free of any extraordinary fatigue or stress factors on the day of the exam.  This means getting a good night's rest, eating normally, and avoiding stressful incidents, arguments, etc. prior to the exam.

If the person is in any pain, we suggest postponing the exam until the cause of the pain has been remedied. If the person is taking regular prescription medications they should continue taking those medications.  If the prescription medications are taken infrequently or as needed then we generally advise not to take these medications until after the exam.  It is ok to take aspirin or other mild over-the-counter medications, which should have no effect on the exam.  It is normal to be concerned about the exam and a certain amount of nervousness will be expected by the examiner.
