For example, the colloquial knowledge that hugs make you feel better. Everyone knows this, that's why you say "I need a hug" when you're having a bad day. But this is not "scientific knowledge", because it wasn't produced by scientific methods, and cannot be acknowledged as valid knowledge by science (i.e., suitable basis for further scientific inquiry, or more precisely, a citation source in a reputable scientific journal) until it has been re-demonstrated that way. This translation of knowledge proceeds at the sometimes slow pace of scientific curiosity, and also at the limit of empirical methodology, which might struggle to reproduce what seems elementary knowledge ("hugs are nice").
