The most frequently asked questions before taking a lie Detector test relate to accuracy and natural nervousness. Here is a list of commonly asked questions about polygraph testing:

How Accurate is a Lie Detector Test?
The greatest misconception of the polygraph is that it’s 100 percent accurate. According to websites like Industry research suggest polygraph accuracy to be between 90 and 95 percent especially when incorporating best practice with validated testing question formats and computerized polygraph technology.

Does the cost of a Lie Detector Test in Sydney, Melbourne and Adelaide, vary from polygraph pricing in Northern Territory?
The cost of a Lie Test in Australia depends on the type of issue, the number of people being tested, the experience and qualifications of the polygraph examiner, including the amount of updated training and the city you are based in. Lie detector testing can cost less in Melbourne, Sydney and Brisbane than it would in regional areas like Darwin because the polygraph specialist would have to travel there.
The cost of a Polygraph test also depends on whether it is for fidelity verification or for focus group relationship testing.

Is it normal to be nervous before lie detector testing?
It is perfectly normal and acceptable to be nervous before a polygraph test, however, lie detection instruments detect deception, not the natural nervousness that everyone has. The questions are repeated for consistency and the scoring is averaged out over a series of data collection phases. Examinees on a lie detector exam are not judged by their body language or personality, but only on their truthfulness on the day.

Is it common to take a lie detector test to address allegations of infidelity?
Lie detection and truth verification examinations are becoming increasingly common in relationships with trust issues. A study at Rutgers University indicated that 56% of males involved in an affair declared that they were happy in their marriage. Statistics and research indicate that females are less likely to cheat than men and are more likely to pass a lie detection test then males.

What are the three stages of a Lie Detector Test in Australian polygraph centres?
The three stages of a lie detector test commences with a pre test discussion, then the asking of the actual predetermined test questions, followed by the calculations of the results. The polygraph administrator will ask a series of reviewed questions several times rather than just once. These are diagnostic questions to provide the “norms” on the graph to which comparisons can be made with responses to pertinent questions. Alternatively, the examiner may ask you to lie to a diagnostic question such as, “Prior to this year, have you ever lied to your parents?” Examinees are advised not to over think the answers to the relevant questions or to try beating the polygraph test.

How many questions can be asked during a specific issue polygraph test?
Lie detector tests are conducted to address a single issue at a time, like cheating. Multiple issues like infidelity and gambling are never asked in the same polygraph test. Separate tests may be booked for different issues. We only use validated testing question formats similar to that used by EPA (refer to the website
