Assume that intelligence entirely an inherited trait and unrelated

You don't need a high IQ to survive in an r-selected environment such as sub-Saharan Africa. In fact it's plausible that it would make you less fit, not more.

The question is about Black people living in America.

We're blacks indigenous to america? No, the place where they evolved and came to be was africa, where survival was easy as fuck and a high iq wasn't very important.

I'm not asking about Africa.

>assume that IQ has a causative relationship with high income as an adult.
>assume
But that's already true. High IQ means better school performance and that means more high paying career opportunities.

The only reason IQ is debated is cause it's not entirely accurate anymore. In 1973 the cut off for retardation was lowered form 85 to 70 because half of blacks were legally retarded back in the day.

nobody is 'responsible' for their genes but what the fuck are you gonna do? give free gibs to people too stupid to function in society? allow shittons of people with low iqs into your country because they're not 'responsible' for their plight?

I guess nobody wants to answer the question. C'mon, knock me out.

American blacks spent millions of years in Africa, and (at most) 400 years here. You don't turn evolution around that quickly.
