Decision Fatigue · Willpower Battery

Willpower battery drained by weighted choices — trivial ×1, moderate ×5, heavy ×10.

Willpower is finite and shared across every decision you make. Trivial choices (what to eat, what to wear) drain the same reservoir as heavy ones (strategy, conflict). This battery gauge tracks the drain — when it dips below 20% you stop deciding and start defaulting.

Willpower = 100 − Σ(count × weight). Batch trivial choices (outfits, meals) to protect capacity for heavy ones. When the battery drops below 20%, you stop deciding and start defaulting — which is how most bad decisions slip through.

How to use

  1. Count the trivial, moderate, and heavy decisions made so far today.
  2. Willpower = 100 − Σ(count × weight). Trivial ×1, Moderate ×5, Heavy ×10.
  3. Above 75% = Full_Charge · 15–45% = Low_Reserve · below 15% = Depleted.
  4. Batch trivial choices (meal prep, uniform wardrobe) to protect heavy-decision capacity.

Examples

10 trivial · 4 moderate · 1 heavy
Drain 40 · Willpower 60 · Drawing_Down — avoid stacking more heavy calls.
20 trivial · 8 moderate · 2 heavy
Drain 80 · Willpower 20 · Low_Reserve — you are in decision debt.

Before you act on the result

Logic tools help expose a tradeoff, but they cannot see the full situation around the decision. Use the result to slow down the choice and name the assumption that matters most.

If one input drives the answer, test that assumption before treating the result as stable.

Frequently asked questions

› Is decision fatigue real? Trust & accuracy

The underlying ego-depletion model has been challenged by replication failures. The practical pattern — late-day choices get worse — is well-supported. Treat this as a useful heuristic, not settled neuroscience.

› How do I restore willpower? How-to

Glucose, sleep, and time off-task. A nap, a meal, or a walk will recover more than "pushing through" ever will.
