Epistemic rationality is the human-made concept of evaluating and updating beliefs in accordance with evidence and probabilistic reasoning. Its parameters are: (1) a norm of belief alignment with available evidence, (2) a mechanism for belief revision when new evidence arrives, and (3) a distinction between epistemic rationality (truth-tracking) and instrumental rationality (goal-achievement). The construct persists through disciplines that operationalize it — epistemology, cognitive psychology, the Bayesian reasoning framework, and scientific methodology — transmitted via teaching and debated in philosophical and scientific literature.

Definition
Why it is in scope
The human-constructed norm of aligning one's beliefs with available evidence — distinguished from instrumental rationality (goal achievement). A standard for truth-conducive belief formation, maintained through scientific practice, evidential norms, and epistemic education. Law 2a: this is the map of the standard, not the natural cognitive faculties themselves.

Epistemic rationality (forming beliefs that accurately track the world) depends on synthesis: updating beliefs in light of evidence, integrating information across sources, and reconciling contradictory data all require synthesizing disparate inputs into coherent updated models. Remove synthesis and epistemic-rationality's core mechanism — belief updating — stops working.

Epistemic rationality (forming accurate beliefs via proper reasoning) requires cognitive control to inhibit biased intuitions, maintain truth-directed goals, and sustain deliberate reasoning. Removal test: remove cognitive control and epistemic rationality stops operating — you cannot hold yourself to epistemic standards, suppress confirmation bias, or execute truth-conducive reasoning strategies. Present-tense dependency: the map of rational belief formation needs executive control to function.

Epistemic rationality is a specific kind of rationality focused on belief formation and evidence evaluation; rationality is the general class of reasoning aimed at truth or coherence. The specific points to the general, not the reverse.
