The eugenics movement, founded by psychologist Francis Galton, aimed to ‘improve’ the human population through selective breeding. This pseudoscience was central to early psychology, with many prominent figures, including 31 American Psychological Association presidents between 1892 and 1947, actively promoting it. Claims that such racist and classist views were simply products of their time are misleading, as the early eugenicists were widely condemned by high-profile critics, such as the author G.K. Chesterton. Despite some modern claims to the contrary, the field of eugenics is not a left-wing movement. Its core tenets—such as the belief in inherent human hierarchies and individual struggle—align with right-wing, neoliberal ideologies that oppose social equality. The fact that eugenics is deeply bedded within the history of psychology undermines conservative claims that the field is inherently biased toward liberal ideas.
