How Accurate is the Test?
The lie detector test has to be conducted with clinical practise and the accuracy of the test depends on four main contributing factors. Statistics from the American Polygraph Association suggest 95-98% and with recent advancements through technology the optimisation of the test continues to improve. No one should quote 100% accuracy as this would not be possible as with any scientific testing there are variances which need to be considered and suitably provisioned for.
4 Main Factors to Determining Accuracy of the Test
- The Person being examined – Must make sure that they are complying with our pre-test requirements
- The Environment – Needs to be void of disturbance or distraction
- The Examiner – Needs to be APA accredited and have relevant testing experience with similar cases to conduct the matter at hand
- The Equipment – We use state-of-the-art Layafette Instruments as used in high level global polygraph testing.
Avoid unqualified independent polygraph examiners who offer you a quick and cheap test. As with many industries there are always rogue traders or private detectives who have bought second rate equipment and not representative of a professional lie detector test. Even though you might be distressed, it is important to be mindful and understand that an accurate and correctly administered private lie detector test will verify truth and prove innocence at best, but equally administered by unqualified people could have a consequential and unnecessary extra burden on your already troubled mind.

The person then being test will go into the examination room and they will be connected to the devices and the testing would commence and be based on the questions proposed and those which the examiner feels are neccessary to achieve accurate results.
Finally, the examiner will then begin their analysis of their findings and take scores from each area of measurement. The examiner will then provide a fully verified report which is always checked by a second examiner to make sure you have something substantial to support or counter an accusation which was initially made. We with the consent of the client are happy to discuss the matter with a 3rd party person if neccessary to help the client move on after the test.
How does lie detector test work?
The person whom is tested is connected to a number of devices which monitor physical signs of deception whilst the examiner will conduct psychometric testing to counter and further build a detailed profile of the test subject. You will generally be asked a number of questions both specific to the issue and more broadly targeted at profiling.
Once the examiner is happy they have gathered enough information to draw conclusions then the test will be stopped and the examiner will use an advanced algorithmic approach to determine if there are true signs of deception. The skill and experience of the examiner are fundamental to the success rate of the test. The equipment also needs to be regularly calibrated and the environment of the test needs to be suitable.
How to prepare for a Lie Detector Test?
10 Things you need to know before taking a Lie Detector Test
- Go to a reputable company rather than an independent as they will have better standards and procedures
- The examiner should not be saying how they are better than the rest as that means they are an independent 1 man band!
- Don’t just book If someone can come out in the next couple of hours! If someone has not got bookings it says something!
- The cheapest test is not necessarily the best – Come on! When in life is cheap also the best quality?
- No one should say it is 100% accurate… 98% at best due to variances like in any professionally conducted test
- It should not be cheaper for 1 question or a short and long version of the test. Process is Process!
- The test should be carried out in a systematic way and the examiner should be conducting extensive fact finding as part of the psycho-analysis
- Every examiner brings different personal experience to the table so make sure they are specialised or from a company that has specialists for different types of tests
- The examiner should not be charging extra for reports – Cheap Test + Expensive Report is not a Cheap Test!
- The Examiner should be qualified in Psychology.
