There are psychologists today who think that higher IQ is a cause of greater wealth and success. I wasn't referring to the original incarnation of IQ theory, which was designed to identify children who needed more attention from their teachers. It then morphed into a justification for racial discrimination. I still hear concepts like country IQ and racial IQ being brought up in conversations. Admittedly, the people talking about this are non-psychologists, but some of them appear to reference the psychology literature.
You're conflating psychologist and psychiatrists. Also, that sort of thing was used to rationalize eugenics a century ago - I'd be very interested if you could found some mainstream psychologists/psychiatrists who espouse those beliefs.
Edit: I see you added "Admittedly, the people talking about this are non-psychologists, but some of them appear to reference the psychology literature."
That's like making the argument that anti-Vaxers are good scientists as they sometimes reference the literature.
