INTRODUCTION

English translation pending.

CORE DEFINITION

A core theme in Charlie Munger's writing, which joins the psychology of reward and punishment with the economic theory of mechanism design. The core claim is that people adjust behaviour toward whatever is actually rewarded, and that the measured indicator is usually easier to manipulate than the goal it is meant to represent. The key qualification is that the design question is not what the rules say but where each participant's best response lands once the rules are in force. Munger's rule of thumb was to look first at incentives rather than at stated intentions.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Actual-reward audit: write down the behaviour the system really pays for, not the behaviour it announces - Best-response walkthrough: predict what each participant does once the rules are live - Counterweight design: pair each manipulable metric with a metric that moves the other way

anchor

Anchor fast decisions

People steer toward whatever is actually rewarded, and the reward structure frequently diverges from the stated goal. Where the measured indicator can be gamed, participants optimise the indicator itself, because the indicator pays out with certainty while the underlying goal is hard to verify. The design question therefore shifts from intentions to predictions: for each participant, what is the best response under these rules, and where does it land? Munger's answer was to inspect incentives before listening to explanations.
