It seems relevant to point out that somebody flagged this article.

Hey, @dang, author here. I don’t think this deserves flagging! The topic is serious and worth thinking about.

Update: I don’t think you’re correct, however, that there is “strong evidence that IQ is linked to group genetics“. This is, for both scientific and political reasons, a very difficult area to work in, and I don’t believe the evidence is in to either support or rebut that claim.
