Over half the guests that come onto The Jeremy Kyle Show want a Lie Detector test, and we’ve carried out more than 500 tests in the years we’ve been on air.
Many guests want to show they are innocent of straying from their loved ones, others want evidence their loved ones are not straying.
Jeremy Kyle’s Polygrapher is Guy Heseltine who’s been doing Lie Detector tests since 2003.
He trained at the Maryland Institute of Criminal Justice in Baltimore USA; the Backster School of Lie Detection in San Diego; the Academy for Scientific Investigative Training in Philadelphia. He is a member of the following associations:
British Polygraph AssociationAmerican Polygraph Associaton
Lie detectors or Polygraphs can be used in a number of circumstances to indicate whether a person is telling the truth or lying. In some areas of the United States and Canada, polygraph results can be submitted as evidence in court. But courts in the UK do not recognise the use of the lie detector.
The test process
A polygraph examination takes around two hours to complete with three different phases:
During the pre test interview the examiner will explain how the polygraph works. He will then discuss the specific issue, develop and review all the questions to be asked. This stage is normally the longest to complete and can take anything from 45 to 90 minutes.
Collection of charts
During this phase the subject will be attached to the polygraph. The set of questions, established during the pre-test interview, will be asked several times. During this stage only the examiner and subject will be present to ensure a controlled environment.
Analysis of charts
Once the examiner has collected the charts he will analyse the results and reach a judgment as to the subject’s truthfulness when answering each question.
Do nerves affect the results of a test?
Practitioners say that under controlled test conditions, nerves should not affect the results. It is expected and understood that all people who undergo a polygraph test will be nervous, whether they intend to answer the questions truthfully or not. An examiner will look for responses over and above the examinee’s normal heightened level of nervousness or anxiety. Typically, an examinee remains nervous throughout the entire testing procedure, rather than at specific points in that process.
The lie detector test is designed to indicate whether someone is being deceptive. Practitioners claim its results have a high level of accuracy, although this is disputed.
