Pathological Lying

 Has no problem lying coolly and easily and it is almost impossible for them to be truthful on a consistent basis. Can create, and get caught up in, a complex belief about their own powers and abilities. Extremely convincing and even able to pass lie detector tests

No sociopath would disagree with the first part. Lies come easy, go easy. However, a sociopath is not by any means a pathological liar. A pathological liar needs to lie. Normally their lies are about their own lives, making themselves more powerful, or more skilled, or better in some way, shape, or form than the people around them. A sociopath sees lying as just another tool. Most sociopaths don't want to be seen as the 'top dog' or the 'guru.' In fact, a sociopath will generally set their reputation as just slightly above average, so they're not a target, but they are still an asset to those around them.

Sociopaths can lie easily, once again, due to Mind over Matter. We believe the lie, just long enough to tell it, and when we tell the lie as though it's truth, anyone who can normally tell lies from truth sees that we believe we're telling the truth, and so believes us. Another of the best methods of lying is to incorporate truth into the stories or lies we tell. If there's concrete fact to back up most of the story, cover the holes in the story with something believable, bland, and unprovable. If no one can prove it's false, then it must be true. Don't lie about something that has solid evidence to prove you wrong, ever. Don't lie if you don't know the whole story. "It's better to keep silent and be thought a fool than to open your mouth and prove everyone right."

A sociopath will, however, create a complex belief system about their own powers and abilities, normally having to do with religion or philosophy. This is really something of a challenge, because this lie isn't truly to the people around them, but to the sociopaths themselves. The belief is a test of skill to the sociopath. If we fully and completely believe in these created ideas, then we're better at lying then we are at detecting lies. If we can't truly believe in this system, then our ability to lie logically isn't good enough. If we can't convince ourselves that the lie is the truth, then we have less chance of convincing others that the lie is truth. If, however, there is a balance, that we believe in this world we've created for ourselves, yet doubt it and try and prove it either correct or incorrect, then our skill with lying matches our ability to detect it, and we prove to ourselves over and over again that we are convincing liars.
