Eugenics Institutions Publish 'Scientific Racism' Studies Purporting to Prove Black Inferiority

Throughout the 1920s, well-funded eugenics research institutions including the Eugenics Record Office at Cold Spring Harbor and the American Eugenics Society produced studies purporting to demonstrate the intellectual inferiority of Black Americans. Carl Brigham's 1923 'A Study of American Intelligence' claimed scientific proof of racial intelligence rankings based on WWI Army IQ tests. These studies were published in mainstream academic journals, cited in congressional testimony supporting immigration restriction, and used to justify school segregation, sterilization programs, and housing exclusion.
