Abstract

Jennifer Lackey makes the case that non-summativist accounts of group belief cannot adequately account for an important difference between group lies and group belief. Since non-summativist accounts fail to do this, she argues that they ought be rejected and that we should seek an account of group belief which can do better by this standard. I briefly summarize Lackey’s argument, to give a sense of the role I see the central desideratum playing, and outline her arguments for that desideratum. I then critique one of the positive arguments she offers for the desideratum, briefly outlining the notion of explication and why I think it would not license the appeal to the Group Lie Desideratum that Lackey’s argument depends upon. This leads me to reflections on the broader project of analysing notions of group belief, and the role I think such endeavours can or ought to play in social epistemology more broadly.
