Here's the thing: IQ isn't a perfect measure of general intelligence. Part of the difference between average white IQ and average black IQ is due to factors other than general intelligence.
General intelligence is absolutely unchangeable. If you were raised in a tribe, your general intelligence would be the same as if you were raised by Bill Gates.
The difference in IQ between blacks and whites is approximately 60% in general intelligence, meaning 60% of it will never ever change without gene editing.
