There is an implicit assumption behind advocating for more minorities or women in elected office, namely, that these officials will bring a new power and influence to their underrepresented groups. However, for women, this idealized viewpoint ignores the social dynamics that subordinate women's words and actions even in “well-balanced” male and female group interactions. Using transcribed verbatim transcripts of 12 state legislative committee hearings, this research analyzes the conversational dynamics of committee members, witnesses, chairs, and sponsors. Sex differences among committee members are highly significant, even after accounting for political factors and structural features of the hearing. In addition, male and female chairs do not conduct hearings in the same way, and these differences affect the behavior of witnesses and committee members. The findings suggest that as the proportion of women increases in a legislative body, men become more verbally aggressive and controlling of the hearing. Women legislators may be seriously disadvantaged and unable to participate equally in legislative policymaking in committee hearings.
