Representing collective reasons for group decisions: The judgment aggregation problem revisited


  • Andrew Knops

    (Department of Political Science and International Studies, University of Birmingham, UK,


This article argues that the discursive dilemma and the judgement aggregation which causes it are based on a misconception of what it means for a group to give reasons for a democratic decision. Judgement aggregation analyses fail to distinguish between the procedure for determining such a decision, which should involve a vote of all group members, and the process for determining the reasons for such a decision, which should only take account of the views of the members that supported that decision. On the basis of this improved interpretation, the article advances a method for representing reasons for group decisions that is both democratic and rational, thus avoiding the choice between these apparently incompatible goals suggested by the discursive dilemma.
