The type of liar who believes their own lies is often a pathological liar, also known as a mythomaniac, who repeatedly tells elaborate fabrications until they blur with reality, sometimes due to underlying personality disorders, trauma, or a deep need for attention, creating a fantasy world where their lies feel true. While they might start with conscious intent, the sheer frequency and complexity of the stories lead to a weak grip on what's real, making them genuinely believe their falsehoods, notes Healthline and Newport Institute.
Self-deception has a prominent role in several medical conditions, such as borderline personality disorder, narcissistic personality disorder, and histrionic personality disorder.
Natural liars are people who can lie easily with great skill and success. They don't believe their own lies, they're just good at lying. Pathological liars: Pathological lying is often a warning sign of antisocial personality disorder (commonly known as a psychopath).
Pathological lying is listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM), although only as a symptom of other disorders such as antisocial, narcissistic, and histrionic personality disorders, not as a stand-alone diagnosis.
Psychopaths are known for their ability to deceptively charm and manipulate others, often to their own benefit. They are skilled at reading and exploiting the emotions of others, using lies and deception as tools to get what they want.
Lack of Accountability: Sociopathic liars rarely take responsibility for their actions. They often blame others or provide elaborate excuses to deflect blame. Pattern of Deceit: Look for a pattern of deceitful behavior over time. Sociopaths lie frequently and about a wide range of topics, often without a clear reason.
THE CORE FEATURES OF PSYCHOPATHY ARE:
Compulsive lying is a complex psychological issue that stems from several different factors. It can be caused by low self-esteem, insecurity, social anxiety, unresolved childhood trauma or abuse, and even neurological disorders such as brain injury or dementia.
First, the narcissist is usually lying when they are absolutely adamant. The knee-jerk, “I didn't do it” response is usually defensive, and the denial is strong and intense. It can make you doubt yourself.
Liars fear being caught, leading to consequences like punishment, rejection, or humiliation, but also fear the exposure of their true, often flawed, selves or the shame and guilt associated with deception, especially when lying stems from trauma or low self-worth. They fear losing control, the damage to trust when lies are revealed, and situations where someone remembers details, as inconsistencies unravel their fabrications.
Liars are insecure
Spreading lies and rumors might be a way for them to connect with others and feel better about themselves. Frequent liars also might lie about their characteristics to boost their suffering ego.
Instead of saying, “I didn't do it,” a deceptive person might shift the focus with a protest statement like “Why would I do something like that?” or “You know me, I would never.” Others might repeat a question verbatim, buying themselves time while crafting a response.
We may engage in self-deception out of anxiety, neediness, desire, or other powerful emotions. As humans, we have emotional attachments to many beliefs, some of which may be irrational. Our self-deception can serve as a coping mechanism for strong feelings of shame about our actions, feelings, or habits.
5 Non-Verbal Signs of Deception in Investigation Interviews
The number one trait of a narcissist is often considered a grandiose sense of self-importance (grandiosity) combined with a profound lack of empathy, where they see others as tools for their own gain and have an inflated, often unrealistic, view of their own superiority, needing constant admiration without acknowledging others' feelings or needs, as highlighted by HelpGuide.org and The Hart Centre. This core creates other behaviors like entitlement, manipulation, and arrogance, making them believe they deserve special treatment.
As a Harvard-trained psychologist, I've found that there are seven phrases you'll hear from highly narcissistic people:

Depending on the type of trauma one experienced, they may feel a need to lie to help protect themselves from any potential threats or danger. Typically, these individuals who lie experienced abuse from others who hurt them physically, mentally, or emotionally.
Key points
People lie for a variety of reasons, such as to avoid receiving punishment, obtain rewards, or keep personal information secret.
Pathological liar signs typically begin between ages 10 and 20, according to a study published in Psychiatric Research & Clinical Practice.
We found support for a moderate link between overall psychopathy and childhood physical abuse, emotional abuse, and neglect, as well as overall childhood maltreatment.
An individual high on psychopathy could feel triggered in many social settings where their expectations go unmet. If someone confronts them, making them seem less dominant or in control—it can send the individual into a deep anger rumination spiral, making forgiveness improbable.
