 It will also, perhaps, say something about whether there can be evidence (arguments) in favor of having a belief that p or bringing about the belief that p, in addition to evidence in favor of p itself (see Reisner 2008). It will presumably also have something to say about disagreement between epistemic peers, and the impact that such disagreement can have on our conception of the doxastic norms, especially if the disagreement is not based on a difference in evidence (van Inwagen 1996, Kelly 2005). Finally, it might take a stand on the more general issue of how higher-order evidence interacts with first-order evidence. For example: in the case of peer disagreement, knowing that a peer disagrees with you is a piece of higher-order evidence regarding your first-order belief.
