Most people have heard of polygraph testing, and they know that it is used to determine whether or not an individual is telling the truth. However, for many people, their only experience of a polygraph exam is seeing it used on television! You may have seen Ken appearing on shows like ‘Couples Court with the Cutlers’ and ‘Chrisley Knows Best.’ However, polygraph testing in Knoxville can be used for more than just great entertainment!

Let’s take a close look at some of the ways many different people use polygraph testing in Knoxville!

1 – Cheating Spouses

One of the most well-known reasons people seek polygraph testing in Knoxville is to uncover a potential cheating partner’s truth. In some cases, the accused partner wants to prove their innocence, and in others, the wronged party wants proof that their suspicions are not unfounded. On occasion, couples will even undergo polygraph tests before embarking on a relationship because one or both of them has trust issues.

2 – Employment Purposes

Sometimes finding the best people to work for you can be challenging. That’s why business owners sometimes use polygraph testing in Knoxville as part of their hiring process. There are, of course, strict regulations that must be followed when using a polygraph to select employees, and we have covered this in a previous post on the topic. It is common for government employees in the United States to submit to a polygraph before they can be hired.

3 – Proving Fraud and Theft

It is also possible for employers and others to make use of polygraph testing in Knoxville in the event of industrial espionage or embezzlement to find out who has been involved in wrongdoing. However, once again, there are essential procedures that must be followed.

4 – Litigation Support

Another key area in which polygraph exams can be a valuable tool is litigation support. We work with many lawyers across Tennessee and beyond to give extra credibility to their cases. Sometimes lawyers want to help bolster their client’s innocence when they are not confident that their evidence will be enough. Lawyers will also use lie detectors when they wish to support or try to discredit other evidence that is being presented. Many different possibilities are depending on the type of case they are dealing with.

5 – Verification of Information

Another less commonly known reason why people book polygraph testing in Knoxville is when media outlets want to confirm the validity of information relating to potentially controversial topics. If their source can pass a lie detector test, it lends more credibility to the information and gives the media outlet more confidence in sharing the story.
