Just fyi there's a GWAS study on the Intelligence journal which makes a bretty good case that IQ and race are related to some degree. I think this is the accepted norm anyway, both Sam Harris (phd in neurology) and also the head of Intelligence journal have defended the Bell Curve in the past, which famously has a chapter in race and IQ.

It's not inherently racist or right-wing to accept this fact.
But it is so when you start advocating for segregation laws, or if you don't know how normal distribution & averages work and assume every person of X race is dumb/smart.

Or if you start having sub-conscious biases, which all of us are inclined to have (see the Rosenthal Rat experiment). in fact many racists are suffering a lot from confirmation bias- they don't think much about it when they see a white person being dumb, but they feel a sense of satisfaction when they see a black person being dumb in the same way. in the end they feel like blacks acted more "dumb", even if this is empirically not the case.

This is the main reason why this research is taboo. People are afraid that shit like this will make people racist, and they're not wrong. Before some alt-right retard comes along with "but is it racist if you know theyre dumb lol", I've made that point already; you'll still have these stupid biases even in a group where everyone is at an equal level of intelligence but they're of different races.
