Compulsive liar

[Dianne]

A [compulsive liar] is defined as someone who lies out of habit. Lying is their normal and covert yet 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
