The quality of decisions degrades over the course of a crisis as the decision-maker's cognitive resources are depleted. Managing this is a governance problem, not a personal one.
What Decision Fatigue Produces
Decision fatigue — the degradation in decision quality that results from the depletion of cognitive resources through sustained decision-making — is a well-documented phenomenon in individual psychology that is systematically underacknowledged in institutional crisis management. As decision-makers exhaust their cognitive resources through the sustained, high-stakes decision-making that crises demand, the quality of their decisions deteriorates in predictable ways: they become more risk-averse, less creative in their identification of options, more prone to relying on simple heuristics rather than careful analysis, and more susceptible to the cognitive biases that careful analysis would normally correct for.
The timing of decision fatigue in crises is particularly consequential: it tends to occur at the later stages of a crisis, after the initial dramatic events have produced a stream of high-stakes decisions and before the crisis has resolved. This is precisely the period when the decisions being made — the decisions about recovery strategy, resource allocation, and institutional adaptation — are most consequential for the long-term outcome of the crisis. Decision quality degrades exactly when decision importance is highest.
The Governance Response
Decision fatigue is a governance problem because it is produced by the institutional design of crisis decision-making — the assignment of decision responsibility to specific individuals without the rotation, delegation, and resource management that would preserve those individuals' decision quality over extended crisis periods. The governance response is institutional rather than personal: designing the crisis decision-making process to rotate decision responsibility, delegate routine decisions away from the highest-stakes decision-makers, and provide explicit recovery periods for the people making the most consequential decisions. These structural interventions reduce decision fatigue not by improving any individual's cognitive endurance but by ensuring that the most important decisions are made by people who are not yet fatigued.
Decision fatigue in crisis is not a weakness of the decision-maker — it is a predictable physiological response to sustained cognitive demand. The institution that does not manage it through process design will manage its consequences after the fact, at much greater cost.
