Biological Determinism

Biological determinism is the view that human behavior, abilities, and social arrangements are determined primarily by biological factors such as genes, hormones, or brain structure, leaving little room for social, cultural, or historical influence. It has recurred throughout the history of the human sciences and has often been used to justify inequality. Cesare Lombroso's theory of the born criminal, Francis Galton's eugenics, and nineteenth-century racial science claimed that social hierarchies reflect natural differences, while Herbert Spencer's social Darwinism presented competition and inequality as products of evolution. Sociologists have long opposed such claims. Emile Durkheim insisted that social facts must be explained by other social facts, and Franz Boas's anthropology demonstrated the primacy of culture over race. Stephen Jay Gould's The Mismeasure of Man exposed flaws in the measurement of intelligence, and Richard Lewontin, Steven Rose, and Leon Kamin criticized reductionist genetic explanations. Feminist scholars such as Anne Fausto-Sterling have shown how biological arguments naturalize gender inequality. Contemporary debates concern behavioral genetics, evolutionary psychology, and neuroscience. Biological determinism remains a key concept for analyzing science, ideology, racism, sexism, and the nature versus nurture debate.
