It is widely maintained that doxastic norms that govern how people should believe can be explained by the truism that belief is governed by the correctness norm: believing p is correct if and only if p. This approach fails because it confuses two kinds of correctness norm: (1) It is correct for S to believe p if and only p; and (2) believing p is correct qua belief if and only if p. Only can (2) be said to be a truism about belief, but it cannot ground doxastic norms
