Decision Fatigue
The erosion of executive quality. Strategies to conserve neural energy, structure choice architecture, and maintain high-level judgment throughout the day.

Willpower and decision-making are not infinite traits; they are finite biological resources powered by glucose and neural endurance. Decision Fatigue describes the deteriorating quality of decisions made after a long session of decision-making.
The Erosion of Judgment
As the Prefrontal Cortex tires, the brain switches to default mechanisms:
-
Recklessness: Impulsive decisions (e.g., eating junk food at night).
-
Avoidance: Doing nothing (e.g., “I’ll decide on this email tomorrow”). This is why judges are statistically less likely to grant parole late in the day compared to the morning.
Conservation Strategies
-
Reduce Variables: Minimize trivial choices (clothing, breakfast) to save neural energy for high-stakes decisions (The Steve Jobs approach).
-
Front-Loading: Schedule the most cognitively demanding decisions for the first 2-3 hours of the day when the “neural fuel tank” is full.
