Decision Fatigue

Decision fatigue is the degradation of decision quality that occurs after a sequence of decisions, produced by the depletion of cognitive resources rather than by information overload. Unlike analysis paralysis, which is produced by too much information, decision fatigue is produced by too many decisions — each choice consumes a finite pool of executive resources, and the quality of subsequent choices declines as the pool depletes. The phenomenon is most visible in high-stakes environments such as medical diagnosis, judicial sentencing, and consumer choice, where the sequence of decisions is long and the consequences are significant.

The systems-theoretic insight is that decision fatigue is not merely a biological limitation but a resource depletion pathology that can be engineered around: by reducing the number of trivial decisions, organizations and individuals can preserve cognitive resources for decisions that matter. The deeper question is whether an organization that demands constant trivial decisions from its members is systematically degrading their capacity for consequential ones. The connection to bounded rationality is direct: decision fatigue is one of the mechanisms by which rationality becomes bounded, not by ignorance but by exhaustion.
