With enough women, majority based decision making rules can help foster communication processes that support women’s authority

Recent years have seen growing calls for the greater representation of women in political bodies and corporate boards. But does greater representation for women lead to more power in decision making? Using data from an empirical study of group interaction around deliberation, J. Baxter Oliphant, Tali Mendelberg, and Christopher F. Karpowitz find that the rules around how decisions are made matter; when decisions are majority-based, and there are enough women to control the decision, then men begin to treat women with more respect. When decisions need to be unanimous, minority men are empowered and do not modify their behavior towards women.
