What was 'scientific racism' in the 18th and 19th centuries, and how did it relate to European colonial projects?

Model answer: Scientific racism refers to the use of ostensibly scientific methods (craniometry, comparative anatomy, evolutionary classification) to argue for inherent, biological hierarchies among human racial groups. Johann Friedrich Blumenbach's racial classification (1775), Samuel Morton's skull measurements, and Paul Broca's brain size studies were used to claim that European peoples were intellectually superior to African, Asian, and Indigenous peoples. These claims were deployed to justify slavery (enslaved people were biologically suited to servitude), colonialism (colonized peoples could not govern themselves and needed European 'civilization'), and racial segregation. The methods were systematically flawed -- measurements were selectively reported, categories predetermined conclusions -- but their scientific framing gave them authority that naked prejudice lacked.
Scientific racism illustrates that methodological rigor and institutional prestige do not guarantee freedom from ideological distortion. Researchers who held racial hierarchies as assumptions found ways to generate data confirming those assumptions. Stephen Jay Gould's The Mismeasure of Man (1981) systematically documented the flaws.
