Well we have a problem with what we mean by these words. I regard them as separate states of mind with believing being inferior.
Knowing requires a high degree of evidence while believing may not require any. Many times belief is nothing but accepting what one was told as a little child and that is why these religions propagate through generations and are local to cultures.

Oh, I don't know. I've seen many people use the word 'know' without a high degree of evidence.
But, I can appreciate your word usage. It's just one of those things that needs to be discussed to come to agreement on what we're talking about. It would be interesting to go to a Christian forum and see how they think of the word 'believe', if they use it closer to my definition or closer to yours.
Which brings me to a possibly interesting question for Jtmoor:
Is it more important on these psychological surveys to retain the specific wording of questions even when different groups think they as different things, or is it more important to accede to the various groups and attempt to frame unique questions per group so that they mean, as much as possible, the same thing between the different groups?
