Accurate Results From a Lie Detector Test in Oxford
Accuracy of a Lie Detector Test in Oxford
Polygraph tests are proven to be as accurate as 95% when the right equipment, examiner and questions are used. When Lie Detectors UK run a Lie Detector Test in Oxford we would only use a single issue method to achieve the greatest accuracy available. Accuracy can be diminished by the wrong questions, an examiner who isn’t qualified, use of old equipment and an environment that isn’t suitable to test in.
Can My Nerves Make Me Guilty When I Am Not?
Absolutely not, this is a very common question that we are asked almost daily. A subject will be nervous from the start to the end of the test, we are looking at reactions to questions rather than someone’s nerves or anxiety. And quite frankly if nerves had an impact everyone would fail where we are seeing pass rates of around 80%. The Polygraph Examiner in Oxford will work with you to make this situation as easy and as comfortable as possible.
Control Question Test
Lie Detector’s UK Examiners in Oxford use the Control Question Test as a physiological baseline. Control questions are asked to make correlations with relevant questions in order to ascertain if a subject is lying. A good Examiner will stick to the Directed Lie Approach when choosing the suitable questions for the test. All questions will be fully discussed with the examinee prior to taking a Polygraph Test in Oxford.
Lie Detector Test - Alternatives
What Is Eye-tracking?
There is a screening tool that uses pupil dilation however it’s not as accurate as a Polygraph Test at 85% accuracy and requires the subject to have a good reading skills. Eye tracking for Lie Detection looks at small movements in the eye within the pupil to ascertain if the subject is being truthful to a series of questions.
Voice Stress Analysis
Voice Stress Analysis was used until recently as its been proven to be very unreliable, it looks for variations in the intensity, frequency and the pitch of the voice.
Brain Observations
Functional magnetic resonance imaging machine shows the use of oxygen by the brain and highlights the parts of the brain using oxygen to determine whether a subject is telling a lie. Again results have shown this not to be very reliable.
Nonverbal Behaviour
Micro expressions or involuntary facial expressions are observed by a high speed camera. Micro expressions can be used to identify truthful or non-truthful behaviour. However again not reliable in the many case studies.
Drugs
Truth drugs including Ethanol, Sodium Thiopental and Cannabis amongst various others have historically been used to obtain information from subjects without their consent. Whilst lots of drugs have been tested there is no one substance that works on all.
