Eliminate recurring micro-decisions with standing rules

Convert repeated low-stakes decisions into rules so willpower isn’t spent on them daily.

Why it works

Willpower and decision-making quality share cognitive resources. Research on decision fatigue shows that after many decisions, judgment degrades and people default to easier (often worse) choices. Standing rules — what to eat, when to work out, which tool to use by default — eliminate entire categories of decision and preserve cognitive capacity for decisions that actually matter.

How to do it

1. List every decision you make repeatedly (lunch, workout timing, which tool to use for X, meeting length).
2. For each, write a default rule that works 80% of the time and commit to it.
3. Treat exceptions as events requiring conscious override, not as evidence the rule is wrong.
4. Review your rules quarterly — some will be right, others need updating.

Evidence

Decision fatigue has been demonstrated experimentally: judges made worse parole decisions late in the day; participants made worse choices after extended decision-making. Reducing the number of daily decisions is a practical application of this finding. Vohs et al. (2008) showed directly that the act of making choices impairs subsequent self-control, and Baumeister et al. (1998) established the underlying ego-depletion account — together giving the "convert decisions to rules" move a mechanism, not just a courtroom correlation. (observational)

The judicial decision fatigue study has faced replication challenges and alternative explanations (lunch breaks confound the finding). Decision fatigue is real but may be smaller than early reports suggested; the principle remains practically sound without over-claiming the magnitude.

Common mistake

Making standing rules too complex or conditional, which turns them back into decisions ("I’ll work out in the morning unless I have a 9am call in which case...") — simplicity is the point.
