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 …
