GROUP KNOWLEDGE, QUESTIONS, AND THE DIVISION OF EPISTEMIC LABOUR

Discussions of group knowledge typically focus on whether a group's knowledge that p reduces to group members' knowledge that p. Drawing on the cumulative reading of collective knowledge ascriptions and considerations about the importance of the division of epistemic labour, I argue for what I call the Fragmented Knowledge account, which allows for more complex relations between individual and collective knowledge. According to this account, a group can know an answer to a question in virtue of members of the group knowing parts of that answer, when the whole answer is available to group-level action. I argue that this account explains a swathe of central cases of group knowledge, as well as explaining some central features of group knowledge.
