A compulsive liar is defined as someone who lies out of habit. Lying is their normal and reflexive way of responding to questions. Compulsive liars bend the truth about everything, large and small. For a compulsive liar, telling the truth is very awkward and uncomfortable while lying feels right. Compulsive lying is usually thought to develop in early childhood, due to being placed in an environment where lying was necessary. A compulsive liar may also have difficulties with poor self-esteem. For the most part, compulsive liars are not overly manipulative and cunning, rather they simply lie out of habit - an automatic response which is hard to break and one that takes its toll on a relationship. A compulsive liar may have difficulties with poor self-esteem.
Psychiatrists, psychologists, clinical social workers, and other mental health personnel use the term 'compulsive lying' when they refer to people who cannot control their lying, that is, people who feel compelled to lie and are aware that they are lying. Therefore, compulsive lying implies impaired ability to control it. The term 'compulsive lying' is not a diagnosis. It is a behavior or a symptom associated with a number of mental disorders [for example, Obsessive Compulsive Disorder]. The term "confabulation" is used to describe lying or invention when the person who is lying is not aware that they are lying. To be more specific, confabulation is treating a fantasy as a fact, without awareness that fantasy has replaced fact."
