But that never shows up in the data? Seriously, people always like to bring this idea up like it's not been studied to hell and back. Socioeconomic is not a stronger factor.
Your data shows one of two things:
1. IQ scores differ between race because of inherent differences in intelligence.
2. IQ scores differ due to outside factors such as racism and socio-economic factors.
Point 1 is racist, you provide no proof for it, and all studies I can find indicate that this is not the case.
So that leaves us with point 2, which is precisely the point the article is making.
P.S: Literally the first result when searching for "socio economic factors iq": https://pmc.ncbi.nlm.nih.gov/articles/PMC4641149/ It probably does not explain the full difference because there are more disadvantages such as racism, cultural factors.
Then why do you suppose IQ is correlated to race? Are black people's brains really different from jewish people's?
Or is it that black people are on average raised in poorer communities, with poorer schools, less educated parents and less access to cultural material?
The issue with you presenting that data as is, like there is a natural hierarchy of races, is that you are omitting the real reason we observe those discrepancies. Socioeconomic status, or place of birth or whatever else.
Seeing how a lot of people in the country are resurrecting some terrible ideologies of the past to justify mass deportation, I really don't see how that helps anything.
