Any time you attempt to analyze a group that contains millions of people you are going to end up with a significant number of individuals who are statistical outliers
But while environment/culture is a factor, it is important that we not deliberately ignore the role genetics play in cognitive ability
"Twin studies of adult individuals have found a heritability of IQ between 57% and 73%[6] with the most recent studies showing heritability for IQ as high as 80%[7] and 86%.[8]. IQ goes from being weakly correlated with genetics, for children, to being strongly correlated with genetics for late teens and adults. The heritability of IQ increases with age and reaches an asymptote at 18–20 years of age and continues at that level well into adulthood. This phenomenon is known as the Wilson Effect.[9] Recent studies suggest that family and parenting characteristics are not significant contributors to variation in IQ scores;[10] however, poor prenatal environment, malnutrition and disease can have deleterious effects.[11][12]"
It's become a very taboo subject. James Watson, who won a Nobel prize for his work with DNA, was stripped of his honors after he refused to lie and say there were not genetic differences that affect the average intelligence of different racial groups
None of this means you have to hate black people or that a black person can't succeed in American society. There are many brilliant black individuals. But it's important to know this stuff because progressives are blaming lower average black test scores on white supremacist conspiracies and attempting to replace math with "ethnomathematics"
And while they want to search for economical reason they will keep crimes and getting welfare...

African American babies adopted by affluent white couples had an average adult IQ 17 points lower than adopted white children

There have been other studies about the genetic differences between demographics that causes the achievement gap

I don’t know man. 70iq average means that a normal 105 iq Japanese guy would be a almost a genius there
