UPDATE
ARGUMENT CLOSED (2025): The argument is now closed thanks to paper by Brown, Wai, and Chabris that tried to rebut the piece below, but confirmed all of its conclusions. The piece, most recent one on IQ and relying on multi-cohort studies, unintentially showed that IQ explains almost nothing in educational attainment, occupational attainment, and …income! And that, in spite of the circularity. I did not notice the paper until 2024.

I agree. From our verifiable traditions, we know that the Devil (Eblīs) has the highest IQ, but this didn’t help him much!
It all boils down onto one’s mindful attitude and moral manners and not much on the brain power. Maybe we need to introduce another “IQ” measure: The Integrity Quotient.
