Abstract The global rise of deliberative democratic innovations, particularly minipublics such as citizens’ assemblies and deliberative polls, has been marked by uneven adoption across advanced democracies. While some countries have integrated these mechanisms into their democratic frameworks, others remain hesitant, raising questions about the institutional conditions that facilitate or hinder their adoption. This study employs qualitative comparative analysis (QCA) to examine how configurations of three key institutional dimensions – consensus democracy, federalism, and direct democracy – shape the adoption of minipublics. Our findings reveal that minipublics are more likely to be adopted in majoritarian systems with strong federalism and limited direct democracy, where they address participatory gaps. Conversely, systems combining high consensus democracy and extensive direct democratic mechanisms, such as Switzerland, often exhibit lower adoption rates, as existing power-sharing structures fulfil similar deliberative functions.
