disbelief" to mean "refusal or reluctance to believe."
I am aware of this usage. I even gave an example earlier about a wife being in disbelief upon learning of her husbands death. However, it has only just now occured to me that this in fact may be how the word is being used in the definition.

Are you sure? Supposing I did, let me try again.
Think of having a belief as having a fifty pound backpack. Ann, Bob, and Charlie are climbing up a hill.
Ann and Bob are having difficulty getting up the hill, for they are both each carrying a heavy fifty pound backpack, but Charlie isn't having any trouble getting up the hill at all, for he has no backpack to carry.
B(G) is heavy, for there is a belief, but B(~G) is heavy too, for there is a belief. ~B(G) isn't heavy at all, for there is no belief.
So, Ann and Bob have something in common. They have a belief. Charlie is different, as he has no belief.
