Ann Oakley is the feminist sociologist who wrote 'Sex, Gender and Society' (1972), where she argued that gender differences are often a result of socialization rather than biology.
Step-by-step explanation:
The feminist sociologist who wrote Sex, Gender and Society (1972) is Ann Oakley. Oakley's work is renowned for challenging the assumption that sex differences are biologically determined, suggesting instead that many of these differences are the result of socialization and learned behaviors. This perspective aligns with the broader understanding within sociology that gender refers to societal roles and expectations rather than merely biological differences, supporting the notion that gendered behaviors can vary significantly across different cultures.
