Decision fatigue: the gradual degradation of cognitive
Decision fatigue: the gradual degradation of cognitive performance and decision quality that occurs over extended periods of sustained deliberation, characterized by a push toward defaults, avoidance, and lower-quality reasoning as executive function resources become depleted
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'decision fatigue' by specifying its genus (cognitive performance degradation) and differentia (gradual degradation over time, characterized by push toward defaults, avoidance, and lower quality). It distinguishes it from simple mental exhaustion and emphasizes the resource depletion mechanism rather than just the outcome, which aligns with the lesson's focus on cognitive load theory and executive function constraints.
