 So the worry is that, although Bayesians have a simple normative framework, they seem to enjoy the simplicity because they idealize away from the complications in humans’ epistemic endeavors and turn instead to normative standards that can be met only by highly idealized agents. If so, there are pervasive counterexamples to the two core Bayesian norms: all human beings. Call this the problem of idealization. For different ways of presenting this problem, see Harman (1986: ch. 3), Foley (1992: sec. 4.4), Pollock (2006: ch. 6), and Horgan (2017).
