The old saying goes that Science ain’t an exact science, and nowhere is that more true than with the Scientific Racism of the 19th century. From its predecessors in the 18th century, we get into the unholy trinity of Pearson, Galton, and Fisher. We talk about craniometry, phrenology, IQ testing, “race development” (now called International Relations), and racism in all your favorite fields, from criminology to anthropology, to political science and economics, to sociology and statistical science itself. We talk about the history, so you can ponder the question: has science moved past all this racist baggage?
