What is a Polygraph Test?

A polygraph or lie detector test analyses the physiological changes occurring in the body while the subject responds to questions in order to ascertain whether the subject is lying about a specific incident. The data about the subject’s physiological responses will be recorded by a skilled polygraph examiner. The charts are then analysed, and based on the analysis, a method of scientific scoring is utilised to ascertain whether the person is telling the truth. We provide lie detector test services for every imaginable situation.

How do Lie Detection Tests Work?

A polygraph test, often known as a lie detector test, typically entails four procedures:

  • The candidate will be connected to the polygraph device. His or Her vitals including Breath rate and depth, heart rate, blood pressure and perspiration will be recorded for the duration of the test. (some newer polygraphs will also record eye movement and pupil dilation)
  • A pre-assessment is the first step that an examiner guides the subject through.
  • Once a baseline is established the examiner will start to answers yes or no question regarding the subject in question.
  • The results will then be analysed for any signs that point to the individual lying and a report will be issued to the person or company that requested the service.
