Judgment Aggregation and the Discursive Dilemma

نویسنده

  • Franz Dietrich
چکیده

Judgment aggregation theory investigates which procedures a group could or should use to form collective judgments (‘yes’ or ‘no’) on a given set of propositions or issues, based on the judgments of the group members. How, for instance, should the citizens of a state reach collective judgments on the three propositions that multiculturalism is desirable, that immigration should be promoted, and that the former implies the latter? And how should a jury in court form collective judgments on the propositions that the defendant has broken the contract, that this contract was legally valid, and that the defendant is liable to pay damages?

Consistent Judgement Aggregation: The Truth-Functional Case1

Generalizing the celebrated “discursive dilemma,” we analyze judgement aggregation problems in which a group of agents independently votes on a set of complex propositions (the “conclusions”) and on a set of “premises” by which the conclusions are truth-functionally determined. We show that for conclusionand premise-based aggregation rules to be mutually consistent, the aggregation must always ...
