1. What is polygraph?

The word polygraph itself means simply "many writings". What we today refer to as a polygraph is a scientific instrument that is capable of simultaneously recording your body physiology.

The polygraphist scores the polygraph charts numerically. He analyzes the physiological data to the relevant questions that were asked and renders an opinion as to whether or not that the client has given answer that can be supported by research. There are three opinions: Deception INDICATED (DI); No Deception Indication (NDI) and Inconclusive (No Opinion).

7. How accurate are polygraph examinations?

There have been several studies over decades, which covered the validity, accuracy and reliability of polygraph examinations. While the polygraph is highly accurate, it is not infallible and errors do occur which may be caused by multiple factors:

It is therefore important for clients to find a competent and certified polygraph examiner who has established credibility. In addition, the polygraph examiner should also be a member of an accredited polygraph organization (Canadian Association of Police Polygraph is the only professional association in Canada for polygraph examiners).

8. Are polygraph examinations confidential?
