 — the truth of \(A\) overrides anything the expert might say. So all of the proposed expert probabilities above should really be regarded as defeasible. Joyce (1998) portrays the rational agent as estimating truth values, seeking to minimize a measure of distance between them and her probability assignments—that is, to maximize the accuracy of those assignments. Generalizing a theorem of de Finetti’s (1974), he shows that for any measure of distance that satisfies certain intuitive properties, any agent who violates the probability axioms could serve this epistemic goal better by obeying them instead, however the world turns out. In short, non-probabilistic credences are accuracy-dominated by probabilistic credences. This provides a “non-pragmatic” argument for probabilism (in contrast to the Dutch Book and representation theorem arguments).
