You really don't need high IQ to do many things in life. How we bring up our kids as Africans or African American is the start of the rot.
It's not IQ. I think it's amazing how the IDW has spread the IQ myth counting on the fact that most people won't bother actually researching the stuff they claim from actual experts.
First of all, Black Americans are disproportionately affected by poisoned water and lead in their houses that has been shown to damage IQ performance; and it affects them right from pregnancy, in disgustingly large numbers.
Secondly, Black American schools are grossly underfunded because of how Americans organize their public school funding using tax from real estate which ensures that only families that were already rich (White!) can/could send their children to good schools whereas a huge number of black people go to places where they are guaranteed not to proceed beyond a certain stage.
Third, the crackdown on the crack epidemic also grossly targeted black people. It is a statistically proven fact that black people, especially boys and men, were arrested and jailed for the same minor drug offences (use) that Whites did in the same degree and proportion but were not targeted. It's incredible the numbers of black boys/men who were thrown in jail as a result, leading to many unnecessary fatherless homes. This continues to happen to the present day.
Fourth, the IQ of Black Americans has been steadily rising each decade since the end of the civil rights movement. So I don't know why people are so quick to follow racists like Murphy in his lazy explanations for complex phenomena when actual IQ experts dismiss those lazy explanations for precisely the above and many other reasons I haven't mentioned.
Outside the developed world, IQ is not seen as capable of comparison because of the wide cultural disparities that it cannot cater for. Just think, giving an IQ test to a Turkana boy, a boy in Kisii who has never left the village, and my Nairobi kids and expecting it to tell you something meaningful about the innate intelligence of Turkanas vs Kisiis vs people in Nairobi. IQ outside the first world will not tell you anything about how innate intelligence of populations compares to each other, and has been shown to
follow development (i.e to increase as development increases, over decades) across all populations--not the other way around.
