Q. Is the polygraph like the lie detector?
A. Yes. The polygraph instrument is a scientific, diagnostic instrument which is often called the "lie detector". It would be more appropriate, however, to call it the "truth verifier". Click here for further information.

Q. I am telling the truth but I am nervous about taking a polygraph examination. How does the polygraph establish the difference between the state of nervousness and reactions as a result of lying?
A. It is quite normal for an innocent person to feel nervous and the polygraph examiner is very aware of this. Nervous reactions which are recorded on the polygraph charts are not interpreted by the examiner as a manifestation of deception. Nervous reactions are completely different from those reactions that are recorded when a person is deliberately lying.
Q. Can a polygraph lie detector test be used for infidelity? Can I test my partner to see if they are cheating on me?
A. If you feel that your husband or wife is lying to you on a regular basis, then a polygraph is not going to solve your challenges.
However, a polygraph can find the truth in relation to a particular issue, for example whether your partner has had sexual contact or sexual intercourse with another person.
If you believe that your partner has been cheating on you, it can be a very upsetting and distressing time. If you feel finding the truth could help you to move on with your relationship then please contact our Clinical Advisers for friendly, unbiased advice.
In situation such as this, we strongly suggest that you seek the help of a qualified marriage counsellor in addition to this polygraph. Our advisers will be happy to provide you with contact details for a number of marriage counsellors in your area.
Q. Can I know what the questions on the polygraph examination will be beforehand?
A. Yes. You will be informed of the exact wording of each question that will be asked of you during the course of the polygraph examination. There will be no "trick" questions.
Q. How long does a polygraph examination take?
A. A polygraph examination takes about two to three hours, however, some may take more or less time, depending on the nature of the issue under investigation.
Q. Why does a polygraph examination take two to three hours?
A. The examiner will give a detailed explanation of the polygraph procedure, how the polygraph works, and he will answer any questions that the examinee may have. The examiner will also inform and discuss the result of the examinee's polygraph examination.
Q. Can you carry out tests in any foreign languages?
A. Our polygraph examinations can be conducted in any language via a team of highly skilled linguistic experts.
Multiple people can be tested at one appointment.
