What is a polygraph exam?
The polygraph exam, often wrongly nicknamed "lie detector test," is a device that measures and records several physiological reactions of the human body in order to detect deception.
Lie detector and polygraph, are they the same thing?
In fact, lie detector is the popular term for the polygraph, which is so named because it records several physiological parameters using a computerized device.
How long does a polygraph take?
The appointment lasts approximately 3 hours. However, the person is only connected to the device for approximately 30 minutes. The remainder of the appointment includes administrative measures (verification of the subject's physical and mental fitness, reading and signing the consent form), the pre-test interview, and the post-test interview.
Can I be forced to take a lie detector test?
No. The polygraph examination is completely voluntary. The examiner requires the subject's cooperation throughout the test. Therefore, the person being tested must remain willing and submit to the procedure of their own free will.
If for any reason you no longer wish to take the test, you can leave at any time.
How many questions can be asked during a polygraph exam?
For the test to meet industry standards and be reliable, the number of questions asked should be limited to three or four. These questions should also cover a single topic for so-called "diagnostic" tests (crime, infidelity, allegations, etc.) or a maximum of four topics for screening tests (often for pre-employment testing situations).
How are the questions asked determined?
Questions must be clear and precise, address specific behaviors, and leave no room for interpretation. Formulating polygraph questions is a crucial step, as any ambiguity can skew the results. It can sometimes take a polygraph examiner nearly an hour to develop the three or four correct questions for a test, even if they may seem simple and obvious to a novice.
Under what circumstances can a polygraph be useful?
A polygraph exam (lie detector test) can be useful in many different situations:
-
For the suspect of a crime.
-
To establish or reestablish the credibility of a witness.
-
In cases of insurance fraud (theft, fire, disability) or CNESST.
-
In cases of infidelity.
-
In cases of allegations of sexual misconduct.
-
In family disputes (theft, succession/inheritance, various intra-family conflicts).
-
For sensitive pre-employment screening.
-
For pre-marital verification.
-
In cases of alimony disputes.
-
For allegations of undeclared work.
-
In cases of immigration issues.
-
To confirm or deny an alibi.
-
For cases of disputes related to intellectual property.
-
In cases of high-level sports competitions (doping, cheating).
-
For cases of alleged damage to reputation.
-
For business issues (theft, fraud, misconduct, drugs, etc.).
-
Etc.
If I am extremely nervous during the polygraph, could that cause me to fail the test?
The candidate's stress level is not an obstacle to taking a polygraph and in no way influences the chances of success or failure. Everyone gets nervous before a polygraph test. The examiner is perfectly capable of differentiating a candidate's general nervousness from their physiological reactions related to lying. This is an integral part of their daily work.
I have high blood pressure, could this affect my chances of passing the polygraph?
No. Although blood pressure is one of the parameters measured, high blood pressure does not affect the test results. Whether your blood pressure is low, within normal limits, or high, lying will cause it to temporarily rise. The polygraph examiner does not evaluate your blood pressure readings, but rather the fluctuations in your blood pressure during the test.
I take several types of medications. Can this affect my polygraph results?
No. Inform the examiner of any medications you are taking so they can be taken into account. However, taking medication does not affect the results of a polygraph test. If you are taking medication, continue your treatment as normal. Do not stop taking your medication or change your dosage before the test.
Is the polygraph reliable?
The polygraph is a completely reliable tool when administered by a qualified professional and built according to recognized protocols. Like the majority of scientific diagnostic tests (x-rays, screening, scans, ultrasounds, pregnancy tests, blood projection analysis, graphology, etc.), the polygraph has a margin of error. However, the polygraph tests offered today have a reliability of around 89 to 94%, which is quite acceptable and comparable to several investigative or diagnostic techniques.
What are the benefits of taking a polygraph test?
There are many benefits to taking what's commonly known as a lie detector test. Depending on the situation, a successful test can help you reestablish your credibility, demonstrate your honesty, resolve conflicts, and demonstrate that you have nothing to hide.
How to prepare for a polygraph?
We invite you to read the detailed article we wrote on this subject on our blog section (available in French only).
Is the polygraph admissible in court?
The admissibility of polygraphs in court varies depending on the jurisdiction and the context. Generally, the test results are not admissible in criminal court, but they are in civil court. In criminal cases, although they cannot be admitted as evidence in court, polygraph tests can still be very useful before a hearing.
As a lawyer, how can a polygraph test contribute to my legal strategy?
Polygraph testing can be extremely useful for lawyers. It can be used to verify the veracity of a potential client's statements before agreeing to represent them, to prepare a client for an official test conducted by a police force, to establish the credibility of a witness, and can be used as a tool for persuasion and negotiation.
Is the polygraph easy to defeat?
No. Polygraph examiners are trained to detect any attempt at manipulation, whether physical, mental, or pharmacological. While some techniques taught online may have been effective for certain tests conducted many years ago, they are now outdated and useless in regards to the instruments and techniques used today.
How much does a polygraph test cost?
The price depends on the complexity of the case and the associated issues (court testimony, high-profile case, etc.).
The cost of a polygraph test at Némésis ranges from $595 for an infidelity test to $795 for a criminal diagnostic test. Prices are before taxes, and travel fees may apply for tests required more than 100 km from our offices located in Piedmont, in the Laurentians region.
Can I get an appointment for a lie detector test quickly?
Absolutely. Typically, you can get an appointment for a polygraph test in less than a week.
Are your services offered elsewhere than in the Laurentides?
Yes, we can travel anywhere in the province of Quebec. However, travel fees apply for tests to be performed more than 100 km from our Piedmont offices. Accommodation fees may also apply for tests to be performed more than 300 km from our offices.
Can I be accompanied during the test?
It all depends on the situation. However, it is normally not recommended to be accompanied during the test and the interview, particularly for reasons of confidentiality and especially because the physiological reactions demonstrated during the test can be greatly influenced by the presence of a third person in the room. We invite you to ask us this question when making the appointment. We will then be better able to answer this question after evaluating the situation and the objective of the test. Please note that someone can wait for you in our waiting room if necessary.
