Binary Gender

Binary gender refers to the classification of people into two distinct and opposed categories, masculine and feminine or male and female, and to the social expectation that everyone fits neatly into one of them. Sociologists distinguish it from biological sex and emphasize that the gender binary is socially constructed, maintained through norms, institutions, language, and everyday interaction. Simone de Beauvoir argued that one is not born but becomes a woman, drawing attention to the social making of gender. Harold Garfinkel’s study of Agnes and Garfinkel’s ethnomethodological approach, followed by Candace West and Don Zimmerman’s concept of doing gender, showed how gender is continually accomplished through interaction and accountability to others. Judith Butler theorized gender as performative and criticized the heterosexual matrix that makes the binary seem natural, while Raewyn Connell analyzed how gender orders organize power and hierarchy. Anne Fausto-Sterling challenged the strict biological binary by pointing to intersex variation, and cross-cultural research documents third and multiple gender categories in many societies. Non-binary and genderqueer identities further question the system. Binary gender remains central to debates about identity, inequality, law, and social change.
