The pathological liar
There is a subtle difference between a pathological and compulsive liar, although it is possible to be both. The pathological liar will repeat a lie over and again, even when they know they’ve been found out. Conversely, a compulsive liar will usually admit to lying and come up with an excuse for it.
Pathological liars are so charming and practised in the art of deceit few people can detect they are lying. However, if confronted they won’t be sorry! They are wholly selfish and will never consider how damaging or hurtful their lies may be to their victims.
It’s usually pathological liars who, when they fail lie detector tests, insist the polygraph is wrong. They’ll deny they have lied, even when there is other evidence to prove they have.
Whilst most white lies are often told so as not to offend or hurt another’s feelings, pathological lies have no real purpose. Sometimes these liars go so far as to incriminate themselves making it difficult to understand why they have lied at all.
