Rationality is the human-constructed practice of guiding belief and action by norms of consistency, evidence, and goal-congruence. It carves the space between unreasoned impulse and formal proof: decisions evaluated by how well they cohere with other beliefs and the agent's stated aims, held together by criteria that can be articulated, contested, and revised. Persistence mechanism: institutionalized in logic, science, law, and education as a teachable discipline with explicit criteria for right reasoning.

Definition
Why it is in scope
Rationality is a human-made framework of reasoning — constructed principles, standards, and methods for evaluating claims and making decisions. It is not the natural biological capacity for thought, but the cultural and intellectual apparatus of what counts as 'reasonable,' varying across domains (logic, science, law, practical deliberation) and epochs.

Rationality is reasoning applied systematically to evaluate and decide. Remove reasoning and rationality ceases to operate — constitutive present-tense dependency.
- cmrehumxg00i3g8vu5x5px5v2DEPENDS_ON →
Rationality as a concept depends on logic: the system of valid inference. Remove logic — remove the rules of valid reasoning — and rationality has nothing to conform to, ceasing to operate as a concept. This is not meta-level (Law 2b): rationality and logic pick out object-level concepts whose relationship is that rationality's operation presupposes logical structure.
