 In addition to using theoretical arguments like these, ethicists of belief can connect doxastic norms by appealing to empirical data. If we discover through investigation that it is on the whole prudent to be morally good, then prudential norms may be able support some of the moral norms. Similarly, if we discover that following moral norms of belief reliably leads to the acquisition of knowledge, then there may be a track-record argument that goes from epistemic norms to moral norms (this would effectively be an empirical argument in support of (P2) above). And if we empirically find that adhering to epistemic norms also promotes the moral good, then there will be an argument from the moral to the epistemic.
