 There is however a powerful argument that any measure of cognitive value that satisfies propriety cannot deliver a fundamental desideratum on an adequate theory of truthlikeness (or accuracy): the principle of proximity. Every serious account of truthlikeness satisfies proximity. But proximity and propriety turn out to be incompatible, given only very weak assumptions (see Oddie 2019 and, for an extended critique, also Schoenfield 2022). If this is right then the best account of genuine accuracy cannot provide a vindication of pure probabilism.
