INTRODUCTION

English translation pending.

CORE DEFINITION

A maxim from the Analects, where Confucius comments on Ji Wenzi's habit of thinking three times before acting and remarks that twice would suffice. Its core proposition is that deliberation reduces impulsive error but itself has diminishing and eventually negative returns, so at some point additional reflection destroys the ability to act rather than improving the decision. The qualifier is that the useful number of passes depends on reversibility and stakes, not on a fixed count.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Stakes pass: weigh the benefits, risks, and consequences of the option in view. - Reversibility pass: check whether the decision can be undone and what it would cost. - Deadline rule: set a time limit and commit when it arrives, so reflection cannot become avoidance.

Anchor fast decisions

Each pass over a decision adds information early and mostly repeats what is already known later, while the cost of delay keeps accruing. Since opportunities decay and the marginal insight of another pass approaches zero, the expected value of deliberating peaks at a small number of rounds and turns negative past it, which is why a stopping rule belongs to the method.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Weigh the benefits, risks, and likely consequences of the action. 2. Check whether the decision is reversible and what reversal would cost. 3. Consider the timing and whether the window will close. 4. Commit once the limit is reached instead of thinking again.
