Do you have a conception of the difference between stuff you "know" (i.e. certain facts that you are sure are correct) and things you "believe to be the case"?

Do you have a conception of the difference between stuff you "know" (i.e. certain facts that you are sure are correct) and things you "believe to be the case"? If yes, are the things you get called out on stuff you had previously categorized as stuff you "know"? If so, you need to think on the distinction between the two. If not, then, what I do is this: If I know something to be correct I am happy to assert it. If I only believe it to be the case, I will caveat it with something like "It is my current understanding that..." and make it clear that I am not the font of all knowledge on the subject, and others may have a more informed opinion. You can mentally prefix this whole answer with a "It is my current understanding that.."
