Abstract

The theory of deliberative democracy is a field of democratic theory that studies the contribution of public discussion, argumentation, and reasoning to the normative justification of democratic decision‐making. In this essay, we first explore two competing visions of the moral ideal of deliberative democracy: the rational consensus conception and the wide conception. This establishes a normative framework for analyzing several important applied issues that arise in thinking about deliberative democracy in the real world: the role of cognitive diversity in deliberative decision‐making, the problem of rational ignorance, inequality in public deliberation, and the problem of group polarization.
