> what lies have been told to which people In practice, this is not a problem. People who lie very much, in my experience, have a couple of strong narratives they build their lies on. Because they follow some vague set of rules (which is easier to remember, especially if you use them repeatedly), it's possible for them to re-invent the same lie for the same situation, every time. On top of that, they are prepared to cover any minor differences that can occur one way or another - mostly by diverting the attention of others to something else. As long as they stay consistent with their lies and manage to stay within the bounds of what others consider plausible, it's very hard to recognize their lies. It's even harder, in practice, because what we consider probable is greatly affected by the flow of conversation and what's happening around it, so with a proper preparation, it's possible to sell almost any bullshit to almost anyone. Well, that's the deep end of conmen and people who use lies - one way or another - for work. However, many people are able to lie easily and they are almost never challenged, at least if they don't exaggerate too much. Our brains are great at filling the holes in the narratives, which has both a good side - art - and dark side - lies.
