INTRODUCTION

English translation pending.

CORE DEFINITION

Wu hui means no regret, an outcome rated one step below great good fortune but clearly above regret. In complex games, pursuing the maximum win usually carries a risk far too large to accept, so the wiser target is no regret: avoid the major errors, keep a fallback in place, and take the modest result rather than gamble everything for the best one.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Set the passing bar: aim for no regret instead of the maximum available win - Keep a fallback: hold a backstop so no single outcome becomes unacceptable to you - Choose robustness: prefer the modest option that cannot fail catastrophically

Anchor fast decisions

In complex games the odds of the maximum win are low while its downside is unbounded, so the expected value favors options with a capped loss. Aiming at no regret filters every move by its worst case first, which removes the bets that would later be regretted, and what remains is a set of choices that can all be lived with.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Decide what would count as a major error before you ever choose 2. Require a fallback for every move that carries real weight 3. Accept the modest result and pass on the large gamble 4. Review the choice by whether it is livable, not whether it is optimal
