Decision fatigue is the phenomenon where making many decisions throughout the day causes your judgment to deteriorate and leaves you mentally exhausted.

Details

What is Decision Fatigue?

Decision fatigue is the phenomenon where making many decisions in a row causes the quality of your choices to gradually decline. Revealed through research by psychologist Roy Baumeister, it shows that our willpower and judgment are like energy — the more we use them, the more they become depleted.

Symptoms of Decision Fatigue

  • Even minor choices start to feel overwhelming
  • You begin making impulsive decisions
  • You procrastinate or give up on making decisions
  • You default to the easiest or most familiar option
  • Decision Fatigue in Everyday Life

    We make approximately 35,000 decisions every day — from what to wear in the morning and what to eat for lunch, to important decisions at work. By evening, our judgment has worn down, which is why we end up making impulse purchases or reaching for unhealthy food — all because of decision fatigue.

    Ways to Reduce Decision Fatigue

  • Make important decisions in the morning: Tackle them when your energy is at its peak
  • Build routines: Automate recurring decisions so you don't have to think about them
  • Reduce your options: Plan your outfits, meals, and other choices in advance
  • Get enough rest: Sleep and proper nutrition are essential for restoring your judgment
  • A word from Mindy: When decisions start to feel hard, it's a signal that your mind is tired. In those moments, it's okay to step back and rest instead of forcing yourself to decide.

    💡 Real-Life Example

    After making decisions in meetings all day, feeling like it's too exhausting to even choose what to have for dinner on the way home — that's decision fatigue.
