between 1907 and 1963, over 64,000 individuals were forcibly sterilised under eugenic legislation in the United States, and in 1972, the United States Senate Committee revealed that at least 2,000 involuntary sterilisations had been performed on poor, black women without their consent and knowledge.
This could be 'justified' by (flawed) research findings which argued that black Americans had lower IQ scores in comparison to white Americans, highlighting a serious issue with socially sensitive research.
