Should you take a polygraph test?
When you’ve never tried to be asked to take this test before, it helps to consult a qualified and competent attorney. Besides, every action and decision you made have their corresponding consequences (which could either favor you or not).
The Process
What will happen once you decided to take this test, understand how it works, what it measures and what are the possible results.
An examiner typically administers the exam in a room where he and the subject are present. In certain cases, surveillance is required to monitor any untoward situation. Examiners begin asking the basic questions such as the personal information of a subject before the questions slowly become confrontational.
Based on a person’s response and results, the examiners can determine whether he or she is lying. However, even the most honest individuals might feel nervous that the results turn inaccurate.
Lie detectors in Business and Criminal Investigations Use
Typically, a lie detector test uk is used to a criminal to produce evidence and determine the truth. In order to strengthen the case against a convicted person, investigators, police and even prosecutors have to gather enough evidence that comes from CCTV, forensic evidence, and even a polygraph test. When asked to be subjected to this kind of test, keep in mind that it’s not mandatory. You can refuse to take one.
There are some businesses that also use this type of test to find out whether they have employees who are dishonest and not loyal to the business. Although the accuracy is not clearly 100%, it can discourage the employees to tell lies. In fact, they might be blunt with everything.
Evidence
A polygraph test can indicate if a person feels nervous as he or she responds to every question. The interesting thing is that most questions are designed to gather evidence and find the truth. For instance, a polygraph examiner could ask dozens of questions while the person remains connected to a machine. But after the machine is turned off or disconnected, most people feel comfortable. As a result, they would omit statements during the post-test interview which, of course, can be used as evidence eventually.
For example, a polygraph examiner might ask the subject a series of questions while the subject is connected to the machine. Queries are also asked after the machine has been disconnected and turned off. This makes the subject feel comfortable. In a post-test interview, a lot of statements are omitted that can be used as evidence.
