 We might do better at understanding the relations rationality requires between your beliefs and your beliefs about them by adding to the requirements of consistency and coherence a bridge principle between the two orders expressed via conditional (subjective) probability. Conditional probabilities say what your degree of belief in one proposition is (should be) given another proposition, here the relevant propositions being a first-order proposition q, and the proposition that one has degree of belief x in q, respectively. A first pass at how to represent a situation where my beliefs at the two levels don’t match comes from its apparent conflict with the synchronic instance of the Reflection Principle (van Fraassen 1984).
