This conference will bring together researchers in philosophy, theoretical economics, formal political science, computer science, mathematics, statistical physics, sociology and engineering who have been independently studying similar questions: namely, opinion formation dynamics, peer interactions and deliberation in social groups, and the implications of these phenomena for the epistemic competency of collective decisions.
Each speaker will deliver a one hour presentation, followed by fifteen minutes of questions and discussion with audience members. Due to the interdisciplinary nature of the conference, we will leave plenty of time for discussion and interaction. We hope this will lead to new interdisciplinary collaborations.
The conference will take place in at 24 rue Lhomond, Paris 75005 (on the campus of the École Normale Supérieure). On Wednesday and Friday, the presentations will take place in room L357/L359. On Thursday, they will take place in room L361. Here is a map of the area:
