This is not to say environment/economics/individuality can't play a factor but seems to be negligent when you consider outlier groups Ashkenazi Jews and East Asian diaspora.
Claims that politics are preventing genetic and psychometric research also seem to drive practitioners in the field pretty nuts; there is clearly and obviously a ton of this research happening "in the west", it just doesn't say what race science activists want it to.
I owe another thread a deeper answer than this, so I'm keeping this brief.
Yes, research continues, but funding priorities and publication incentives do shape which questions get investigated and for past few decades these researches were taboo and funding taken away from those attempting to study it.
I'd encourage looking at the actual publication record rather than characterizations from either "activists" or critics. The data tells a more complex story than the simplified narratives on either side.
You know you're in trouble when people start implying that actual genomic and quantitative psychological research in academic labs is suspect because of "taboos". In fact, since you made that point, and since I really shouldn't be digging into this before responding to the other person I said I would respond to: I'll leave it there.
Also, by populations, do you mean groups of particular types of people or just groups of people in general? If anything, I thought IQ really only had anything close to merit at large population levels. Much of what I have read clearly fails at an individual level.
However, if you are talking about IQ's application in regards to populations like one race vs. another, then yes, I think the pushback is well deserved.
