We investigate associations between adherence to femininity and choice of college major using a sample of university women in the United States. Our results indicate that general conformity to feminine norms is related to postsecondary field of study. With background factors controlled, general conformity to feminine norms is associated negatively with women’s odds of choosing STEM and doctoral-track medicine majors, as well as arts and humanities majors, relative to other fields of study. Our multivariate results also indicate that level of conformity to specific feminine norms, including norms for being relationship-oriented, caring for children, and being domestic, is related to postsecondary field of study, especially for choosing a major in arts and humanities, business, and communication and journalism. Taken together, our findings suggest that cultural norms about femininity contribute to ongoing gender segregation of academic fields of study. [ABSTRACT FROM AUTHOR]
