Do some people believe their own lies?

Comments

Good question. I suspect that the answer is 'yes', but we need to be clear that there are some puzzles about so-called 'self-deception' that need to be avoided. It's not plausible that I could lie to myself, fully knowing that I'm doing so, and also believe what I'm telling myself. Instead, we often *shroud* lots of what we tell ourselves in such a way that its untruth is not self-evident. So here I am with a plate of oatmeal-raisin cookies. I like them a lot, and although I know on some level that I shouldn't eat very many, I'm *extremely* clever at coming up reasons why I can have just one more. (Had a rough day, will run an extra mile tomorrow, raisins are pretty good for you, you know the drill.) So I might convince myself that I can clear the plate. But to do that I have to somehow shroud the fact that I know on some level that I shouldn't.

The upshot is that a direct answer to your question is: Some people (maybe most of us) believe things that we know on some level are lies (but usually when we do we--usually temporarily--lose sight of the fact that we know this). It's only afterwards that we admit to ourselves, faced with the empty cookie plate, that what we told ourselves was bull!

By the way, _Madame Bovary_ is (among other things) a brilliant case study of this phenomenon.
