I think you've asked the best question yet on this thread.
Should we avoid certain subjects in scientific research because we don't like where they may lead? No, I don't want to say that.
On the other hand, I'm not going to choose to do that research. I have no shame in saying many of my fundamental decisions on life issues are based on theology, not science. If someone else wants to do that research, that's up to them. I think a better subject would be the relationship between cultural values and intelligence rather than between gene pools and intelligence, since I believe the way parents raise their children is the primary factor in how children turn out.
And your point about the Chinese is quite interesting. The tremendous racial bigotry in much of Asia against black people exceeds anything in modern America or Europe. If someone is going to do major genetic-based research on racial intelligence, it's much more likely to happen in Asia than in the West, and we may have to deal with a “Bell Curve” book being published by Chinese authors seeking to “prove” that Chinese genetics and culture combine to make their race the natural leaders of the lesser peoples of the world.
I continue to believe intelligence is mostly based on how parents raise their children, but modern Asians are perhaps best suited to make a credible case for intelligence being based on race, with their race being better than ours.
Let's be careful where this racial theorizing can take us. I'm not at all convinced that the decline of Europe, America, and Western civilization in general gives much reason to believe in Anglo-Saxon or Northern European racial superiority.

That has already been done by Charles Murray in his just published book, “Coming Apart”:
