Chapter Summary<\/summary>\nThis chapter explores the entanglement between psychology and the eugenics movement in the early twentieth century. It examines how psychological science became a mechanism through which people and populations were categorised, evaluated, and managed. Psychologists developed tools such as intelligence tests, classification systems, and statistical models which, far from being neutral instruments, became technologies of power. These methods legitimised policies of segregation, institution-alisation, immigration control, and forced sterilisation. The chapter introduces Michel Foucault\u2019s concept of biopower as its critical thinking tool. Biopower refers to the way modern states regulate life through expert knowledge, including psychological expertise, in order to exert control over biological processes. The chapter uses this concept to analyse how psychological ideas about intelligence and deviance were embedded in institutional practices across Britain, the United States, and Scandinavia. While highlighting the central roles played by psychologists, the chapter also includes critical voices that questioned biological determinism and emphasised the role of environment and social inequality. Through a critical historical lens, the chapter invites us to reflect on psychology\u2019s complicity in exclusionary systems of power and its legacy in contemporary debates around intelligence, genetics, and social policy. It argues that understanding this history is essential not only for ethical reflection but also for reimagining the role of psychology in promoting equity and justice.<\/p>\n<\/details>\n<\/div>\n\n\n\n
