People so desperately want a way to objectively rank themselves against each other that they'll believe IQ is a good way to measure intelligence because their ego needs it to be true.
I suspect the opposite - people who consistently score poorly want so desperately to believe that they're special that they insist that they have some innate, untestable brilliance.
> Savant sees IQ tests as measurements of a variety of mental abilities and thinks intelligence entails so many factors that "attempts to measure it are useless".
I have the non conventional idea that some of the biggest opponents of any form of innate talent are the already privileged.
Thus they can pay lip service to the idea of ending privilege all the while explaining why for now they should be our natural enlightened rulers
