The thing is, the unknown-ness often varies over time. So it could be things you know but sometimes forget that you know.

So, "accurately"? Yes. Completely? Of course not.

I think the OP gave a pretty good way to recognize at least some of these. But you're right that one can probably never know their own entire constellation of these assumptions.

Heck, I would never insist that any answers I get must be comprehensive.
