90% of my self-touted ability to "guess the facts" is probably in fact down to my amazing ability to learn something and then forget it (but to forget only on a conscious level!). Meaning probably I heard it before, or had it explained, and just forgot all about it until it came up again years later, when suddenly I was forced to marshal my fantastic "guessing abilities": Hey! I bet I can figure out what that is. Right again? Who knew!
The other 10% as we know is pure psychic paranormality, not to be even tried-at explanation-wise. Some things it's better not to know.
