This paper continues Dietrich and List's [2010] work on propositional-attitude aggregation theory, which is a … generalised unification of the judgment-aggregation and probabilistic opinion-pooling literatures. We first propose an algebraic … framework for an analysis of (many-valued) propositional-attitude aggregation problems. Then we shall show that systematic …

In the theory of judgment aggregation on logically connected propositions, an important question remains open: Which … aggregation rules are manipulable and which are strategy-proof? We define manipulability and strategy-proofness in judgment … aggregation, characterize all strategy-proof aggregation rules, and prove an impossibility theorem similar to the Gibbard …
