You're living under a rock if you believe nobody is studying or confronting IQ and culture and how it relates to race. It's just it's not really intellectually profound to repeat and rehash the same old "scientific racism" that's been going on for the last century and a half, that's why you hear less of it.
I just graduated from an elite American college, and almost everyone there was extremely condescending about the idea that race and IQ were at all correlated. They felt similarly about racial culture and success. In these powerful people's eyes, the underperformance of non-White and non-Asian races is ~100% the fault of White people and their machinations.
Of course there's a good reason for that fad - scientific racism is a pseudoscience that was created in order to "prove" the inferiority of races and to justify colonialism, slavery, racism, social Darwinism, and racial eugenics.

The correlation between race and IQ is openly "admitted" right there in the into paragraph of the Wikipedia page! If academia is "hiding" it they sure are doing a bad job. - https://en.wikipedia.org/wiki/Race_and_intelligence
I rarely comment on HN and usually just register a new account when I do. I can understand why people would register a throwaway though, considering the blind hostility people like you have in these types of discussions.

Wha? The lead calls it a "contentious debate" and the body cites quality sources that suggest a causal connection.
