With deliberative democracy becoming increasingly incorporated into political processes, the instances of citizens and politicians meeting in deliberation, so-called mixed deliberations, is increasing too. While these are important steps towards more deliberative systems, the mixed deliberation setting nonetheless introduces certain risks regarding equality. Citizens and politicians have different deliberative capacities, which could affect the process of deliberation. Moreover, political inequalities such as gender gaps may be more evident in deliberations where politicians are present. This study focuses on a series of mixed deliberations in 2018 about a proposed municipal merger in Finland. Using content analysis of speech acts (N = 3404) as well as pre- and post-deliberation surveys (N = 225), we analyze patterns according to participant status (politician/citizen) and gender regarding dominance, deliberative discussion quality, and impact on internal and external efficacy. The findings show that politicians dominated the discussions and achieved a higher deliberative quality than citizens. The findings also revealed that women achieved higher deliberative quality in their speech acts.
