Earlier quoted context omitted.
"you clearly know very little about burnout" You may disagree with my statement about the cause of burnout, and you may be correct about that. But it's unlikely you know enough about me to judge how much I know (or don't know) about burnout.
But you yourself made the same error, claiming that lots of people are simply mistaken about the causes of their burnouts and that you know their condition better than themselves.
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.
