Abstract

Paradoxes in group decision making (like Condorcet paradox in social choice theory and the discursive dilemma in judgment aggregation) are characterized by the fact that the combination of consistent individual positions may lead to inconsistent collective outcomes. However, this problem may overshadow another diculty: when is a group decision defendable? In this talk I will use abstract argumentation theory to tackle this question. I will present three aggregation operators that ensure collectively rational and defendable group decisions, and study them with respect to Pareto optimality and strategy-proofness.
