La sagesse collective : principes et mécanismes

Colloque des 22-23 mai 2008, organisé par l'Institut du Monde Contemporain du Collège de France, sous la direction du Professeur Jon Elster.

Intervention de Christian List.While a large social-choice-theoretic literature discusses the aggregation of individual judgments into collective ones, there is relatively little formal work on the revision of individual judgments in group deliberation. I develop a model of judgment revision and prove a baseline impossibility result: any judgment revision function satisfying some initially plausible conditions is the identity function, under which no opinion change occurs. I identify escape routes from this impossibility and argue that successful group deliberation must be holistic.: it cannot generally be restricted to one proposition at a time but must focus on larger webs of interconnected propositions. This echoes the Duhem-Quine .holism thesis.on scienti.c theory testing.My approach opens up a new way of analyzing deliberative processes axiomatically.
