bounded rationality is a concept based on the fact that rationality of individuals is limited by the information they have, the cognitive limitations of their minds, and the finite amount of time they have to make decisions.
This looks to me like "reality." Why it's interesting to me is that we don't like to acknowledge that our beliefs have flaws. All of them. When we're correct, it's mostly by accident. We never have all of the information, we aren't all omniscient geniuses, and we don't have enough time--even when we use what time we have well. This is a useful idea to me.
The problems I see with our discourse about belief (and this is what drives me to keep bringing it up) is that it's rarely discourse. It's not people coming together to consider what might be true. It's usually people aiming to convince everyone else that we're right and everyone else is wrong.
