 The applicability of merging techniques developed in computer science to judgment aggregation problems does not mean that the two disciplines have the same objectives. As we have seen, the original motivation of belief merging was to define ways to aggregate information coming from different sources. Since the sources can have different access to the information, no externally given agenda is assumed. This is a difference with the judgment aggregation framework, where individuals are required to submit their opinion on a given set of items. Belief merging and judgment aggregation do not only differ in the type of inputs they aggregate. They also output different results: a collective base satisfying some given integrity constraints for belief merging, and a collective judgment on the given agenda for judgment aggregation.
