 Hitchcock and Sober argue that there is no one answer to this question—and then present a series of several cases. Insofar as predictivism holds in some and not others, their account of predictivism is clearly a local (rather than global) account. In cases in which Penny and Annie propose the same theory, or propose theories whose AIC scores can be computed and directly compared, there is no reason to regard facts about how they built the theory to carry further significance. But if we do not know which theories were proposed, or by what method they were constructed, the fact that Penny predicted data that Annie accommodated can argue for Penny’s theory having a higher AIC score than Annie’s, and thus carry an epistemic advantage.
