IQ is objectively a good measure of human intelligence. High IQ people have higher educational achievement, income, etc.
I never said it’s the cause. We’re trying to find a measure that correlates well with actual intelligence g
IQ correlates with g, but also income/education correlates with g because smarter people do better in these metrics.
IQ doesn’t make you smarter, but smarter people can do better on IQ tests
smarter people do better in these metrics.
Smarter by what measure? IQ?
You’re using circular reasoning here.
Income and education levels are not the same thing as intelligence, nor are smarter people higher earners or more well educated.
IQ correlates best with educational achievement. Educational achievement is best predicted by your zip code. Poverty creates sharp educational disadvantages.
Intelligence, as measured by your maximally attainable levels of obtaining knowledge and skills, is something that the majority of people will never test their limits of.
IQ tests do not measure that maximum, only how far along that trajectory you might have come compared to your “peers”.
Therefore: IQ tests are 1 step removed from just asking someone where they grew up, how much college they attended and how much money their parents made.
It has nothing to do with measuring that underlying factor and everything to do with measuring socioeconomic status.
It was a crude tool invented by eugenicists to promote genocide and you should stop using or respecting it at all.
