I'm very excited about this piece for The Nation. It draws parallels between the contemporary rhetoric around "race and IQ" and other forms of scientific racism and the once wildly popular "racialist" movement in the US. It combined three popular ideas – eugenics, scientific racism, and immigration restriction – into a stew of white supremacist ideology that dominated both high- and low-brow circles from the end of the 19th to the mid-20th centuries.
The idea that scientific racism was repudiated after World War II is a myth that, if at all, only holds true among elites. Belief that there are scientific, genetic, or biological differences that prove the superiority of white Europeans has never gone away. People merely learned that it was not socially acceptable to say it out loud. Now it's becoming more acceptable and people are responding predictably.
