Abstract
Vohs and colleagues show that active choosing (not mere deliberation) impairs later self-control — a primary lab bridge from ego depletion to everyday decision fatigue.

Key findings
- Choice costs — Selecting among options depletes more than reviewing the same options without choosing.
- Carryover — After choosing, people show less stamina, less persistence, more procrastination, and worse arithmetic quantity/quality.
- Implementation vs choice — Implementing someone else’s choice is less depleting than making the choice yourself.
- Enjoyment buffer — Expecting the choice task to be enjoyable softens early depletion, not a long stack of choices.
Limits
Part of the broader ego-depletion literature — effect sizes and boundary conditions remain debated; use as a constraint design cue, not as absolute physiology.
Application
When the morning opens as a stack of votes, reopen Decision Fatigue and remove one choice before willpower is asked to carry the day.
