Our statements were qualitatively different. Compare: A) Each living human has 2 legs B) Sharlin has 2 legs Taken literally, B is a subset of A, so A is the stronger statement. But in normal speech, it's clear that when someone makes a claim about members of a large group, they're making a statement that usually applies to members of that group. And not claiming to have specific knowledge of every single member. Because statement B is more specific, I probably need more specific data before I make it.
