Yes, the IQ difference is no longer controversial. It used to be when people supposed it might be due to cultural bias in the tests but that problem got solved, somehow.
Unfortunately, the topic is too politically sensitive for most people to talk intelligently about. When I find people who say it's entirely environmental, I usually try to ask their reasons in hope of discovering something but so far they've never come up with anything stronger than speculation and insults. As far as I know, there's no evidence that it's not genetic but I'd love to discover some. The Minnesota study I mentioned looked like it should have finally got to the bottom of it, but they made up a new hypothesis based on an uncontrolled variable after the data came in, which is bad science.
What I have found is that the whatever the cause is, it happens before the age of about 4. That's useful to know if you propose improving racial equality through better education because by the time kids go to school, it's already too late. Any such effort has to be multi-generational.
The social implications of the general society getting this wrong in either direction are huge, so it's definitely worth being honest about.
