Unqualified Polygraph Examiners ruin the Reputation of the Lie Detector Industry
Critics of this polygraph assert that the machine does not detect lies and they are completely perfect! The lie detector test steps physiological reactions for deception. Unqualified polygraph examiners are not trained to analyse these responses accurately.
The test is only as good as the polygraph examiner’s qualifications and expertise. In addition to calculating meticulously structured questions as well as the pre-test interview using a subject, in depth analysis of answers is paramount. Unqualified polygraph examiners may, and frequently do, make it wrong and that is what provides the lie detector industry a bad reputation.
How does a polygraph instrument operate?
Most people will have seen a lie detector test in films. The focus is generally on the graph the machine generates where traces are published. These twisted lines are created from sensors attached to the human body and reflect changes in respiration, blood pressure, perspiration and heart rate (pulse). When changes happen, an expert lie detector examiner is able to assess the results and determine dishonesty.
More modern technology that is used now collects data using electronic recording systems rather than the moving pencil analogue system featured in movies.
Lie detector tests may take several hours to run Because of the different phases That Have to be improved as outlined below:
Pre-test — this is the initial phase once the examiner sits together with the topic to describe how the test will be conducted. Any queries the topic might have about the test are answered and questions which are going to be asked during the examination, reviewed. It is important that the topic has a clear understanding of these questions before the exam begins.
Data — that the second phase is when the examiner asks the questions which were ready and gathers the data in the subject’s physiological responses.
Analysis — the last phase includes analysis of the data that has been collected. Having researched this information, the examiner will compute if deception was present or not.
What to look for when purchasing a lie detector test
Lie detector tests are used in recruiting screening and law enforcement as well as by private people. You will want the most accurate results and the only way that you can ensure this is by checking out the credentials of your examiner.
Ensure that the examiner is UKPA (UK Polygraph Association) accredited. They are the best in the world. Use a company which has the most up-to-date in lie detector technology and is discreet. Confidentiality is essential when dealing with deceit.
Beware of unqualified polygraph examiners
To get a lie detector test to succeed it’s very important that the examiner is qualified and licensed. You would not let an untrained mechanic fix the brakes on your car and hiring unqualified polygraph examiners falls into the exact same category.
