> IQ is often used in "scientific" racism to promote pseudoscientific social theories
1. They say IQ doesn't measure intelligence because according to them "Intelligence is the ability to solve problems". Well IQ at least claims to do that with its with its fluid intelligence component. Maybe creativity is independent of IQ, and also corresponds to better problem solving skills, but that doesn't change the fact IQ is still a predictor of problem solving skill.
2. If you can prove IQ can be boosted, that would be revolutionary. There's the n-back that improves IQ according to some studies, but that's highly controversial. But in any case, I don't see how not being able to change it makes it a bad measure. Me not being able to make myself taller doesn't make height a bad measure.
3. People not handling well knowing their intelligence doesn't have anything to do whatsoever with IQ being a good or bad measure of intelligence.
4. Again, people using metrics to be racist is an argument against measuring intelligence, not against IQ itself. You could make the same argument about literally any other system measuring intelligence.
A point I find interesting is "school improves IQ". What if the reason we can't seemingly improve people's IQ was because the school system already brought them to their full IQ potential? Maybe when we're trying to increase people intelligence, because we're testing on people already at school, it's like conducting studies on how to get muscular on people who are already maxed out gym bros. It's gonna be very hard to get them more muscular/intelligent if they're already reached max allowed by their body through intense daily workout/schooling.
