I'm not sure exactly what the parent comment has in mind, but the Lex Fridman podcast recently covered race topics relating to intelligence, I wonder if it's related to that: https://youtu.be/g9RxrsvcS-k

The YouTube video is obviously a touchy subject, and I haven't had time to dig into the interviewee yet to verify his claims, I only skimmed the Wikipedia article relating to the subject, and it's very thorough, and very well cited from the looks of things: https://en.wikipedia.org/wiki/Race_and_intelligence?wprov=sf...
