Mini-public deliberations, in which ordinary citizens are selected by lottery to discuss and participate in the planning processes of local governments, have spread around the world. Why deliberation? The deliberative process provides more than just an opportunity for participation and a sense of acceptance of public decision-making and policy-making processes. Deliberative democracy is expected to have the epistemic function of guiding the outcome to the right one. In this paper, I aim to show that the study of collective intelligence in epistemic democracy provides a new mechanism for explaining that deliberative procedures can improve the correctness of outcomes (i.e., the substance).
