Paradoxes
As mentioned in the introduction, the recent interest in judgment aggregation was sparked by the observation that majority voting has some surprising properties, which have become known as the 'doctrinal paradox' and 'discursive dilemma'. These, in turn, are related to a much older paradox of majority voting: 'Condorcet's paradox'. A good part, but by no means all, of the current literature on judgment aggregation still revolves around the question of what the best response to the doctrinal paradox and discursive dilemma is. However, the theory of judgment aggregation is not confined to, and in fact goes well beyond, the study of voting paradoxes.
