This essay focuses on recent proposals to confer decisional status upon deliberative mini-publics such as citizens' juries, Deliberative Polls, and citizens' assemblies. Against such proposals, I argue that inserting deliberative mini-publics into political decision-making processes would diminish the democratic legitimacy of the political system as a whole. This negative conclusion invites a question: which political uses of mini-publics would yield genuinely democratic improvements? Drawing from a participatory conception of deliberative democracy, I propose several uses of mini-publics that could enhance the democratic legitimacy of political decision-making in current societies.
