I am not the one making claims here, you are.
We have a friend who wears a hearing aid. As he talks, he tends to get louder and his wife usually has to shush him. He’s a retired pharmacist, so it’s not a matter of IQ. IMHO, the OP is painting with an extremely large brush, based on zero data.
Or it could be going the other way. Maybe people tend to ignore what they’re saying because they’re dumb and they begin talking louder to compensate. In which case, they started out just dumb and then became loud.
You know who else was loud?
HITLER!
And he put ketchup on hot dogs.
Well at least he did SOMETHING right. ![]()
Uh huh. The either/or of having intelligence and social skills and being dumb but good with people again.
Because he’s making shit up.
