I think this is a really interesting question. To me, if I hear a claim, I might say I accept it as knowledge or believe it as a worldview.

For example, I get irked by people asking if I “believe” in climate change. To me, it’s not a matter of belief: there is a body of knowledge being scrutinised by extraordinarily smart and talented people. I accept the existence of and need to mitigate climate change.

On the other hand, do I believe we’re not alone in the universe? I can’t rely on knowledge, it’s a lot of intuition.
