From aggregation to deliberation
Aggregative democracy treats citizens' preferences as fixed and focuses on summing them through voting. Deliberative democracy holds that preferences can change through discussion and that decisions should rest on public reasons all can accept. Habermas (1996) argued that opinion formed through uncoerced communication in the public sphere confers legitimacy on law and policy, and Gutmann and Thompson (1996) proposed reciprocity, publicity and accountability as principles of deliberation.
Institutions and experiments
Through the deliberative poll, in which randomly selected citizens discuss balanced materials and are surveyed again, Fishkin and Luskin (2005) showed that deliberation actually changes citizens' knowledge and opinions. Ireland's Citizens' Assembly and British Columbia's Citizens' Assembly on Electoral Reform are leading examples. Thompson (2008) addressed how such empirical work relates to normative theory, and Chambers (2003) surveyed the theory's development.
Critiques and limits
Sunstein (2002) warned that discussion among like-minded people can produce group polarization, moving them to more extreme positions. Difference democrats argued that deliberative norms favoring rational argument may exclude minorities with different styles of speech. Dryzek (2000) extended the theory into discursive democracy encompassing contests of discourse in civil society beyond the state, and how to realize deliberation in large societies remains an open challenge.
