In discussions of the underrepresentation of women in professional philosophy, those sceptical of discrimination as an explanation often suggest that gender differences in interests are a plausible alternative hypothesis. Some suspect that if women’s differing interests explains underrepresentation, then interventions suggested by the discrimination hypothesis might be unnecessary—or even risky. I argue that one needs to consider how stereotypes might influence interests, and that doing so can provide a more even-handed assessment of the risks involved in proposed interventions.
