Personally, I would be ecstatic if we could raise US Black IQ even from 85-89. IQ differences are quite sharp and noticeable towards the lower end for some reason, and 89 IQ is the IQ of the average human. It has also been estimated that a ~90 IQ is necessary in order to create a well-functioning modern society.
To give you an idea of the difference, Hispanics in the US (mostly Mexicans) have ~90 IQ, and US Blacks have 85 IQ. Hispanics do quite a bit better on all sorts of variables than Blacks. Now if we could get the Black IQ up to Hispanic level, I still think Blacks would act a lot worse than Hispanics, but they might perform better in school, have lower dropout rates, do better at occupational achievement and improve on lots of variables from where they were before.
I think they still might act pretty bad because the bad behavior seems to be due to things other than that 85 IQ. The 85 IQ is a problem, but it can’t explain the sky-high Black crime rates very well. For instance, US Black IQ is 85. US Polynesian and Amerindian IQ is 87. There’s not much difference. The Polynesian and Amerindian crime rates are only 2X the White rate, while the Black crime rate is ~6X the White rate.
So whatever causes all this Black crime, there’s more to it than an 85 IQ. There are other things going on there, and who knows what they are. Nevertheless, I suspect that a 90 IQ US Black group would have a lower crime rate than an 85 IQ US Black group simply because crime tends to decrease as IQ goes up and increase as it goes down, and the increases and decreases can be quite dramatic at the lower end of the scale (below 100).
