Polygraph Knoxville

Did you know that there is more than one type of liar? The kinds of lies they tell and their reasons for doing so range from harmless 'little white lies' to harmful lies. Some of the worst types of liars are the ones you will likely need to seek a polygraph in Knoxville for, while the harmless lies can often be forgiven or brushed aside with ease. Let's take a look at some of the most common types of liars and why they are untruthful.

Pathological Liars

If you come into contact with a pathological liar, they are the type of person who tells lies constantly, often for no apparent reason. Sometimes, they may not even realize that they are telling lies. They are not just incapable of being honest with other people but also with themselves. It is practically impossible to have any authentic relationship with someone who is a pathological liar, as their sense of reality shifts on a whim. This type of liar is not necessarily dangerous or cruel. Their lies are a compulsion, and though they may cause hurt, this is rarely intentional. They may have some redeeming qualities, but they are not someone you will ever be able to trust completely. It may not be suitable to have a polygraph in Knoxville where a pathological liar is involved as they may not know that they are lying, which will affect the physiological responses usually exhibited by liars.

Intentional Liars

There are some similarities between intentional liars and pathological liars, but the one key difference that is important to take note of is that intentional liars are entirely aware of their behaviors. They lie for fun or entertainment. It can give them a sense of power or control, knowing that they can push someone's buttons by lying to them. Intentional liars will lie simply to provoke a reaction and will often pass it off as a joke. However, there is a malicious or cruel intention behind these lies.

Manipulative Liars

Manipulative liars tell lies to get what they want. They are laser-focused on the end goal and will say anything to make sure they achieve it. Sometimes this comes in the form of flattery in order to make a sale, secure a date, or otherwise get something from you, but it is almost always disingenuous. You will never truly know where you really stand with a manipulative liar. Do they actually care about you, or are they just using you to achieve something? This is why we see a lot of manipulative liars taking a polygraph in Knoxville as their spouses or business partners try to get to the real truth of their relationship.

Protective Liars

One of the most common types of liars asked to do a polygraph in Knoxville is the protective liar. This is the type of liar who is going out of their way to conceal or protect information. This could be relatively harmless if they are loyal friends or spouses, but it can also be incredibly dangerous since they could be covering wrongdoings - either their own or someone else's! They may not have any moral objections to lying as long as doing so serves them. The problem with this type of liar is who or what they choose to protect. While their secrets could be harmless things that they feel embarrassed about, they could also be something much darker in nature. When a protective liar is covering up an affair, theft, or other crime, that is when you may want to have them take a polygraph in Knoxville to uncover the truth.

Tactful Liars

Not all liars are out for themselves. You could even label the tactful liar as considerate! These are the liars who tell well-meaning white little to keep those around them happy. They are telling you everything is going to be okay, even when you know things are going horribly! They will never tell you that your butt looks big in a dress or that your new haircut looks like a scarecrow should model it! Tactful liars want to spare everyone's feelings, and they have the best intentions, but unfortunately, it can make it tricky to get an honest reply.

These are just a few of the types of liars you may encounter in your life, but there are many others. Each of them has a different motive for untruthfulness! Some liars are relatively harmless; you may allow them a pass when they fib! However, others can cause damage to your relationships, reputation, and daily life. These are the liars that it is important to expose. We can help by administering a polygraph in Knoxville to help uncover the truth allowing you to plan whatever your next steps are going to be.
