Arthur Jensen (1923-2012) was one of the most prolific psychologists of the twentieth-century. He’s so famous that there is a word named after him: “jensenism.” Jensen is remembered for arguing that black people are stupider than white people and there wasn’t much you could do about it. What distinguished Jensen from your racist uncle was that Jensen dressed up his argument in statistics and published it in psychological journals. Another thing that might distinguish Jensen from your racist uncle (unless your racist uncle is much worse than he’s ever let on at Thanksgiving) is that Jensen palled around with neo-Nazis and admirers of Nazi racial thought. People who’s views were basically recapitulations of Nazi race theorist Hans F.K. Günther. The recent awful Quillette article cites Jensen as a reliable source as do many other “race realist” writers nonetheless.
