 Defenders of Rational Monotonicity will argue that, if we find these counterexamples plausible, it is because we are under-representing either the structure of the agents prior beliefs, or of the information that triggers the update. If we were to describe these in realistic detail, they argue, we would not be convinced by these counterexamples. For an elaboration of this line of defense, see Section 5 in Lin (2019). Other criticisms of Rational Monotonicity do not rest essentially on the plausibility of counterexamples, but on the incompatibility of Rational Monotonicity with competing norms of inquiry. One such criticism, due to Lin and Kelly (2012), will be discussed in Section 4.2.4. For another example, see Genin and Kelly (2018).
