What is the definition of an epistemic norm? In what ways does it differ from a consistency norm or a rationality norm? Specifically, are epistemic norms a superset of rationality norms?
EDIT: Would it be correct to say that "epistemic norms" are just those norms which govern the acquisition of beliefs? Would this include prudential belief norms like "believing P would be useful for me, therefore I have an epistemic reason to believe P even if P isn't true or even if all of the evidence indicates that P is false"?
