FAQ’s
What is a Polygraph?
The word polygraph literally means “many writings”. The polygraph used today is an instrument that records physiological reactions caused by the autonomic nervous system. The instrument records the physiological changes caused by the body’s “fight or flight” reflex.
The polygraph works by tracing changes in a person’s physiological conditioning during questioning. These changes are recorded directly on to the polygraph charts in order that they can be reviewed. Some of the changes that occur may replicate those that have been linked with truth or deception for many years. These physiological changes have been the subject of various research projects and our examiners have undertaken many hours of polygraph chart analysis instruction to interpret them.
How reliable is Polygraph Testing?
There is no doubt that the polygraph is highly reliable, providing the person using it is properly trained and the technique they use is validated. The American Polygraph Association (APA) has gathered over 200 studies on the subject. Based on twelve separate studies involving 2174 actual cases since 1980, evidence suggests that qualified polygraph examiners are 98% accurate in their overall decisions.
What happens during a Polygraph test?
A polygraph test will take a minimum of 1.5 hours but may take up to three hours. The test comprises of three parts.
A pre-test structures interview the polygraph examiner will complete required paperwork and talk with the examinee about the test. During this period, the examiner will discuss the questions to be asked and familiarize the examinee with the testing procedure.
Collection of charts , the examiner will administer and collect a number of polygraph charts. Following this, the examiner will analyze the charts and render an opinion as to the truthfulness of the person taking the test. The examiner, when appropriate, will offer the examinee an opportunity to explain physiological responses in relation to one or more questions asked during the test. It is important to note that a polygraph does not include the analysis of physiology associated with the voice. Instruments that claim to record voice stress are not polygraphs and have not been shown to have scientific support.
Chart analysis and post-test interview.
Can you fail the Polygraph test if you are nervous?
Being nervous before a polygraph exam is common and not unusual. Being nervous doesn’t cause a person to fail a polygraph test, – lying does.
Is it possible to beat the test?
Provided that examiner conducting the test is trained and qualified it is highly improbable. The polygraph is a medical instrument that records changes in a person’s autonomic reactivity whilst they answer questions, and If a person engages in behaviours in order to distort the polygraph tracings, it becomes evident to a trained examiner when he sees the tracings.
In most cases it is easy for a qualified examiner to determine if an examinee is attempting to alter the outcome of a test. When such behaviour is identified, a result of “purposeful non cooperation” is given.
Can someone under age 18 take a Polygraph?
Yes, but the examiner must first have written consent of a parent or guardian. However, most examiners will not test anyone less than 14 years old barring extraordinary circumstances.
What Questions Can be Asked?
The examiner will work with you to construct questions that cover the test issue as well as meeting the strict rules for the latest polygraph techniques.

- Media and current affairs – Polygraph tests can help the media ensure their sources are truthful and trustworthy.
- Employee Theft / Fraud – Polygraph tests can be administered in these situations for truth verification.
- Family Law – Matters of issue pending before a court or administrative agency can utilise the polygraph for truth verification.
- Sporting and Tournament Federations - to minimise the possibilities of cheating.
