Abstract: The standard model of knowledge, $$(\varOmega ,P)$$ ( Ω , P ) , consists of state space, $$\varOmega $$ Ω , and possibility correspondence, $$P$$ P . Usually, it is assumed that $$P$$ P satisfies all knowledge axioms (Truth Axiom, Positive Introspection Axiom, and Negative Introspection Axiom). Violating at least one of these axioms is defined as epistemic bounded rationality (EBR). If this happens, a researcher may try to look for another model, $$(\varOmega ^{*},P^{*})$$ ( Ω ∗ , P ∗ ) , which generates the initial model, $$(\varOmega ,P)$$ ( Ω , P ) , while satisfying all knowledge axioms. Rationalizing EBR means that the researcher finds such a model. I determine when rationalization of EBR is possible. I also investigate when a model, $$(\varOmega ^{*},P^{*})$$ ( Ω ∗ , P ∗ ) , which satisfies all knowledge axioms, generates a model, $$(\varOmega ,P)$$ ( Ω , P ) , which satisfies these axioms as well.
