An evolutionary psychologist cannot be as smart as a good theoretical physicist, otherwise he would be one.
The problem with psychologists is not that they are not so smart as they think. It is rather that they are idiots.
An "idiot" here I use here in the sense of someone of someone with an average I.Q. or lower that thinks they are a genius.
But to be fair this applies to just about anyone in the ludicrous "social sciences". Now there is an oxymoron if I ever heard one
