Previous research has found systematic differences in the behavior of women and men members of parliament (MPs). We advance this field of study by looking at written parliamentary questions to government ministers and considering sender and receiver dynamics. We ask to what extent MPs adapt their communication style to the gender of the minister they address. We hypothesize that written parliamentary questions are overall more likely to be similar in style to questions by other MPs of the same gender, and that this is more likely the case when the receiver of the question is of the same gender. We use machine learning to get a domain-specific measure of gendered language, and study 31,396 written questions asked in the Norwegian parliament between 1998 and 2021. We find support for our hypotheses. Women and men MPs generally use different language in their questions, and the language is more gendered in this way when they address a government minister of the same gender. Our findings shed new light on parliaments as gendered institutions.
