Do we really need to state the obvious here?
IQ?
Some people are more predisposed than others to have dysfunctional cultures?
Some people prefer cannibalism to agriculture?
“IQ?”
Some of those countries have average IQs in the 50s.

Yes we really do need to express the obvious
It would be a huge step
Some groups are smarter and more logical on average than others
And some of the defining characteristics are racial
They are not less smart on average due to their skin color
Nor are there not exceptions that exceed the mean of tropical Africans and all other racially defined groups and sub groups and hybrids
And at the bottom is geographic and culture influenced evolution
Blacks are on average lagging everywhere they exist
Amerindians same thing
Arabs too....largely ...distinct racial sub group....also stunted by a raider religion
You can easily look within any racial group and find who excels and who doesn’t and it does carry forth genetically as does lack of intelligence
I see it all around me even in my own kids
