pathological liar, she sounds like a hypocrite as well.
Pathological liar refers to a liar that is compulsive or impulsive, lies on a regular basis and is unable to control their lying despite of foreseeing inevitable negative consequences or ultimate disclosure of the lie. Generally lies told by a pathological liar have self-defeating quality to them and don’t serve the long term material needs of the person. Therefore pathological lying is lying that is caused by a pathology, occurs on a regular basis, is compulsive or impulsive & uncontrolled, and has self-defeating, self-trapping quality to it.
Lying or self-deception is a part of everyday human interactions. In many cases lying can be beneficial for those who lie and those who are being lied to. Most of this type of lying with positive consequences occurs in a controlled way, thoughtfully, with careful weighting of beneficial consequences. Unlike these, the lies told by a pathological liar are uncontrolled and are likely to have damaging consequences.
Pathological lying covers a wide range of lying behavior, from pseudologia fantastica to habitual lying. Lying is a commonly found clinical component with people who suffer from impulse control disorders such as gambling, compulsive shopping, substance abuse, kleptomania etc. Pathological lying is generally caused by a combination of factors, which may include genetic components, dysfunctional or insecure childhood, dyslexia or other type of cerebral dysfunction. Such conditions may host environment that is likely to emerge chronic or pathological lying as an adaptive defense mechanism. Dysfunctional family, parental overprotection, sibling rivalry, mental retardation are among many causes of pathological lying.
Habitual pathological lying is, as the name suggest, habitual. Habitual liar lies so frequently, that it becomes a habit, as a result, he/she puts very little effort in giving a thought about what the output is going to be, nor does he/she care much to process whether it’s a lie or not, it’s simply a reflex & very often can be completely unnecessary or even opposite to his/her own needs. If he/she stops & thinks about it, he/she knows clearly it’s a lie.
Habitual liars lie for a variety of reasons, which include, but are not limited to:
Take advantage of the situation or misguide a rival
Avoid confrontation or punishment
Cover up lack of knowledge
Cover up embarrassment
To entertain oneself or others
Reinforce self-esteem, because of failing own expectation
Receive unearned praise or avoid disappointment or disproval
For no reason whatsoever
Habitual liars gives very few if any psychical or vocal signs of lying, due to the effortless nature of lying. That said, since he/she gives a very little thought to his/her lies, they are usually inconsistent & obvious.
Fear is a major contributor in developing habitual lying in a child & further advancement into adulthood, more so in conditions when the child finds truth telling results in more frequent or more severe punishment. Lack of appreciating and likelihood of unwanted consequences of telling the truth may result in frequent opting out for lying, which often involves less punishment & therefore becomes more desirable.
