 The foregoing passage places some limits on the metaphysical relations between member attitudes and group attitudes. It tells us something about when group propositional attitudes occur, without implying anything about when the latter attitudes are justified. But social epistemologists are interested in the relation between the epistemic statuses of members’ beliefs and the epistemic status of group beliefs. List and Pettit address (something like) this question by exploring the sorts of judgment “functions”, i.e., rules for aggregation, that might come into play.
