Abstract

ABSTRACTIn Democratic Reason, Hélène Landemore makes an epistemic argument for democracy. She contends that, due to their greater cognitive diversity, democratic groups will engage in superior deliberation and information aggregation than will groups of experts; consequently, the quality of their policies will be better. But the introduction of value diversity into Landemore's model—which is necessary if the argument is to apply to the real world—undermines her argument for the epistemic superiority of democratic deliberation. First, the existence of value diversity threatens to stop deliberation prematurely. This has the effect of making the outcome of group deliberation more dependent on individual ability, which gives groups of experts a distinct advantage. Second, the introduction of value diversity raises the question of how to understand the standard of correctness of an epistemic argument, which Landemore does not adequately answer.
