 In addition to formal connections between the two types of aggregation problems, from a conceptual point of view judgment aggregation extends the problems of preference aggregation to more general decision problems. Although the models provided by social choice have improved our understanding of many familiar collective decision problems such as elections, referenda and legislative decisions, they focus primarily on collective choices between alternative outcomes such as candidates, policies or actions. They do not capture a whole class of decision problems in which a group has to form collectively endorsed beliefs or judgments on logically interconnected propositions. Yet, as the examples given in the introduction also show, such decision problems are common and not limited to court decisions. Pettit (2001) coined the term of discursive dilemma to highlight the fact that such problem can arise in all situations in which a group of individuals needs to reach a common stance on multiple propositions.
