Lie Detection Services: How to Uncover a Pathological Liar


Noticing the white lie your fiancé tells your mom about how he loves her cooking can be amusing, but hearing your friend lie to their colleague that they grew up in London when you have been to their family home in Cape Town can be alarming. Uncovering a pathological liar is often difficult as dishonesty is interwoven into their personality and separating the truth from the lies can be messy. We have highlighted the three ways on how you can uncover the pathological liars in your life. Polygraph Truths offers lie detection services that can assist in uncovering a pathological liar in your home or business so that you can begin taking supportive steps to assist the pathological liar.




What is a Pathological Liar?


Pathological liars will lie continuously and compulsively. The lies are often created to boost their self-esteem, fulfil a fantasy, overcome guilt, deny reality, or manipulate people for self-benefit, but in some cases, there is no clear benefit or reason for the lies. Pathological liars often lie without any consideration for the personal consequences or how their lies will affect others, and in most cases, they do not show remorse for their deceitful tendencies. Pathological liars can either be aware that they are lying and demonstrate distressed tendencies or be completely unaware of their lies and believe they are being truthful.


We have highlighted the characteristics of pathological lying that must be present for someone to be identified as a pathological liar.


Frequency: Frequent lying is what characterises a pathological liar, such as the person who lies every day about trivial matters that do not warrant being lied about. Your friend relaying a dramatic exaggeration of the truth of an event to a captive audience at one party is not a signal that your friend is a pathological liar.


Length: For someone to be categorised as a pathological liar, they need to display deceitful tendencies for six months or longer. The length of time is important as it demonstrates that there is a true underlying problem rather than a temporary issue the person may be dealing with.


Self-defeating: Although most pathological liars tell lies for self-benefiting reasons, many of the lies that pathological liars tell are obvious, extreme, and sometimes ridiculous. This then affects their relationships, experience in their workplace, and social standing, and thus impacts their entire life in a negative way.




How Can I Uncover a Pathological Liar?


When a friend, family member, or colleague continuously lies to you, the trust in your relationship will become violated and tarnished. While being lied to can cause frustration and anger, pathological liars need support to alter this destructive behaviour. Uncovering a pathological liar is the first step to being able to assist them with this condition and offer support. We have highlighted three essential ways to uncover a pathological liar in your life.


1) Note The Signs:


Pathological liars typically demonstrate key signs that they are lying. Most of these signs require that you pay careful attention over an extended period to ascertain whether or not the person is a pathological liar or is simply just lying in certain scenarios. We have highlighted a few of the main signals of a pathological liar.


Exaggerated and Complicated Lies:


Pathological liars often tell lies that are exaggerated, complicated, elaborate, and in certain instances, ridiculous. A simple question asking about their day can lead to a story about them walking home from work, being kidnapped by masked figures, fighting themselves free, and running away barefooted from an abandoned warehouse at the harbour. The lies can then range to the extreme of having a long-term severe illness that warrants care, support, and sympathy from those around them. If a person consistently tells exaggerated and complicated lies, this is a clear signal that they are a pathological liar.


Vague or Generalised Statements:


The category of lies can vary from extremely dramatic, detailed, and outlandish to vaguely dismissive. A pathological liar can create a fictional girlfriend and validate her lack of presence at events with work-related excuses or her being abroad, which on the surface would initially seem believable. They can also avoid the truth by responding with generalised statements or long stories which distract from the original question. This signal would require you to spend time carefully listening to the person to determine if they are a pathological liar.


No Apparent Benefit:


While the majority of pathological liars will lie for a personal benefit, there are cases where there appears to be no apparent benefit or reason for the lie. If you asked your partner to go buy bread, and they return telling you that there is no bread in any shops but you easily find bread at your closest store, there is no way to justify this lie with a reasonable explanation. When people are lying for no apparent benefit, you can then be concerned that they may be suffering from a tendency for pathological lying.


Strong Belief In Their Lies:


A concerning sign in pathological liars is when they demonstrate a strong belief in their lies. When you have known a friend for your entire life and overhear him telling people about a tragic childhood experience that can in no way have occurred, this should raise an alarm. If confront them about this unrealistic tragic childhood experience and they insist that it is true, this is a sign that you need to take supportive action.






A clear signal of a pathological liar is inconsistencies in their stories. One minute the large scar on their arm was caused by a shark attack in their youth, and the next minute the explanation is that they had a tumour that had to be removed. Pathological liars lie so frequently that they can struggle to keep a grip on the lies that they have told which allows for inconsistencies to sneak in. Pathological liars will often avoid seeing people regularly due to fear of being uncovered for their inconsistencies.


Defensive When Questioned:




Pathological liars often lie to protect their self-esteem, and will therefore feel threatened when you question them. If you remark on an inconsistency or an exaggerated story that they have told, they will most likely react defensively or attempt to cover up with additional lies. While this can be frustrating and overwhelming, it is a clear signal that they are denying reality and need professional assistance.


2) Psychologist:


Taking note of the different signs can be difficult, therefore, you may need to acquire assistance from a professional. One way to uncover a pathological liar is to insist that they attend a session with a psychologist. A psychologist will be able to pick up any warning signs of pathological lying tendencies and begin a supportive treatment program. Pathological liars often lie to their self-detriment, which warrants the need for professional assistance and support.


Pathological lying can also be a cause for concern as it is often a symptom of an existing personality or mental disorder. People who suffer from antisocial personality disorder, narcissistic personality disorder, and obsessive-compulsive disorder can demonstrate compulsive deceitful tendencies and lack of remorse that can be leading to the person’s pathological lying.


Before you recommend seeing a psychologist to your friend or family member who is demonstrating signs of pathological lying, you will need to gather information. Take note of any instances when you recognise that the person is lying and keep a record. Once you have a record, you can then present the information to the person to demonstrate their deceitful tendencies. We recommend doing this without any aspects of accusation or anger, but rather offer a safe space and a gentle recommendation to see a psychologist. This should hopefully encourage the pathological liar to willingly seek professional assistance.


3) Lie Detection Services:


In many cases when a pathological liar is confronted about their lying, they become dismissive or defensive. This may be caused by the fact that they are not aware of their deceitful tendencies or are attempting to manage their self-esteem through denial. Lie detection services can be a useful tool to provide concrete evidence to a pathological liar that they are indeed lying and should seek professional assistance.
