What does "show me the incentive" mean?

It’s Charlie Munger’s shorthand for incentive-caused bias: to predict behaviour, look at what people are rewarded for, not what they claim to intend. Incentives shape outcomes more reliably than stated goals.

What is a perverse incentive?

A reward that unintentionally encourages the opposite of its goal — like paying for dead rats to cut a rat problem, which leads people to breed rats. Behaviour follows the reward, not the intent.

How do you use the incentives model?

When behaviour seems irrational, map the real rewards and penalties, including hidden ones. To change behaviour, change the incentives so the reward aligns with the outcome you actually want.

Incentives

Also called incentive-caused bias · Economics & psychology

Incentives are the rewards and punishments that drive behaviour. To predict what people will do, look not at what they say or intend but at what they are actually rewarded for. As Munger put it: "show me the incentive and I will show you the outcome."

How it works

Whenever you want to explain or predict behaviour — your own or an organisation’s — map the real rewards and penalties at play, including hidden and perverse ones. People rationalise, but they respond to incentives, often unconsciously, and the structure usually beats the intention.

How to use it

Diagnosing why a team or company behaves "irrationally" — usually it’s responding rationally to its incentives.
Designing systems: align what you reward with the outcome you actually want.
Spotting perverse incentives, where a well-meant reward produces the opposite of its goal.

Worked example

A call centre rewarded for calls-per-hour will rush customers and resolve nothing, driving repeat calls — the metric is hit while the goal (served, happy customers) is missed. The incentive, not the staff, produced the failure.

Where it fails

Over-applied, it slides into cynicism — treating every action as pure self-interest and missing the genuine values, norms, and altruism that also shape behaviour.

The deeper point

It is the most reliable predictor of behaviour we have, precisely because it bypasses what people believe about themselves. Almost everyone thinks they’re above their incentives — which is exactly why the incentives win.
