Well, we here agree that beliefs should pay rent. So you see the sentence "this sentence is false" or similar. What new things do you expect now?

This feels like the wrong step in the dance to me. Haven't you just thrown away all of mathematics? What new things do you expect after solving a quadratic equation?

User:Tiiba is correct. Math (after mapping to real-world predicates) allows me to more quickly form reliable expectations about the world. The claim that "this sentence is false" does not. Therefore, I can leave beliefs about the latter unassigned without epistemic or instrumental penalty.
