Why do negroes in America have an IQ of 85 per average ? But not 74 IQ like their natives. A short answer

[Reinhard_Heini]

Firstly.
The colonists did select them, that’s why only the strongest and mostly the “smartest” only could get into America, not some random negroes.
2. They have an admixture, also if 24% European blood, that’s why they are smarter than their native people too.
3. They were natural selected, also in the US when they arrived there. That’s why they survived, they needed at least some intelligence.

*Blacks have an average 85 IQ, but it depends per study, I will take this one below.
Other studies like Jensen show another results, that’s why it’s seen.

I expected the reasons, interesting.

Do you know something about the intellect “roof” of other races?

Such as other West Eurasians (Jews being extremely smart makes me think MENAs aren’t capped, and Caucasus ethnic groups are very Euro adjacent so I guess they’re the same), and East Eurasians. We know about East Asians but what about first nation Aussies, AASIs, Austronesians and especially Amerindians.
