To be clear, a lie detector test employs questioning methods and technology that record physiological characteristics, such as heart-beat and pulse, to be able to find the reality or falsehood in the person acquiring the test. The most widely used test to measure truth or falsehood will be the polygraph test. While this test is given by a certified and qualified examiner, the accuracy of the test could be between more than 80%.
Some have mixed eeling about the lie detector test
Remember; some feel that a lie detector test is not reputable. In some instances, the examiner could be swayed from the individual’s physiology or perhaps the examiner might be biased. Obviously, many people are nervous when they take this test, while others are calm and collected. Moreover, some may control their physical reactions, which may totally throw-off the test results.
Some just like the notion of a pre test and post-test interview
However, some state that in case a pre test and post-test interview are done, then the examiner could more easily see what kind of signals are now being found whenever a person is anxious or being untruthful through the exam. On the other-hand, if a lie-detector test is stated in a company’s policies included in an anti theft program, the test might prevent dishonest behavior among employees.
Another point-of-view
Another pointofview is an honest employee might have poor answers towards the test because he/she was scared of the test and their physical reactions for the fear were misinterpreted by the machine.
To consider, a lie detector test has advantages and disadvantages but also for the test to become of-value it'd be determined by the company and the way they would like to utilize and employ the test. Visit http://bristolpolygraph.co.uk [1].
