Listener letters on brain development

Charles Murray & Richard Herrnstein's book 1994 The Bell Curve caused tremendous controversy on its publication by positing a link between intelligence and race. But this certainly wasn't the first time someone had made this argument, nor would it be the last. This week, Josh and June take a look at the foundation of the eugenics movement in North America, track its close relationship with the development of IQ testing, and discover some surprising links to German, Italian, and American fascism.
