A psychological concept describing the declining quality of decisions after extended periods of decision-making. Parameters: (1) cumulative decision count — the number of choices already made in the session, (2) decision complexity — the cognitive load per individual decision, (3) domain — the area of decision-making (financial, moral, mundane). Persistence mechanism: empirical research in social psychology, teaching in behavioral economics, application in policy design (choice architecture, default options). The concept maps how finite cognitive resources are depleted through repeated acts of will and judgment, producing a measurable degradation in subsequent decision quality. [formal: defectio facultatum | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made psychological concept describing the deteriorating quality of decisions after a long session of choice-making. Developed through research by Baumeister and colleagues on ego depletion and self-regulation. The map tracks how cognitive resources are consumed by repeated decisions, impairing subsequent judgment and self-control.

Decision fatigue is a specific phenomenon where decision quality deteriorates after prolonged choice, falling under the broader framework of bounded rationality (limits to human decision-making). INSTANCE_OF direction: specific phenomenon → general category. Removal test confirms: decision fatigue IS a kind of bounded rationality — a concrete manifestation of how human rationality is constrained.

decision fatigue IS a specific kind of cognitive bias. A competent speaker would call decision fatigue 'a cognitive bias.' The which-came-first test confirms cognitive-bias (epoch 0.35) predates decision fatigue (epoch 0.5). INSTANCE_OF: the specific (decision fatigue) points at the general (cognitive-bias), per Law 9.

Decision fatigue operates through depletion of executive resources — remove executive-function and the mechanism of decision fatigue ceases to operate. Law 8 removal test: without executive resources, there is no resource depletion.
