## Core Concept

Moral hazard is when someone takes on more risk because they know they won't bear the full consequences. The insulation from consequences changes behavior — people act differently when they're spending someone else's money, driving someone else's car, or borrowing against someone else's future.

The classic example is insurance: you drive less carefully when the insurer pays for the crash. But the pattern is everywhere — bailouts, guarantees, subsidies, and any system where risk and reward are decoupled.

## Why It Matters

Moral hazard isn't just "people are irresponsible." It's a structural incentive problem. Rational actors *should* take more risk when they're insulated from consequences — that's the individually optimal play. The damage is systemic, not individual.

This is what makes it hard to fix: the behavior is rational at the individual level but destructive at the system level. You can't solve it with appeals to responsibility. You solve it by realigning incentives — making the risk-taker bear more of the consequences.

## Where It Shows Up

- **Insurance:** Deductibles and copays exist specifically to counter moral hazard — they force the insured to bear some cost
- **Banking:** "Too big to fail" banks take excessive risk because they expect government bailouts. The 2008 crisis was a moral hazard cascade.
- **Student loans:** Government-backed loans with potential forgiveness → borrowers borrow more, universities charge more. See [Debt-Forgiveness-Economics](/patterns/debt-forgiveness-economics)
- **Agent design:** An AI agent with no cost signal will over-generate, over-explore, and over-build. See [Effectiveness-Over-Efficiency](/patterns/effectiveness-over-efficiency), Autonomy-Through-Constraints
- **Management:** A manager who never lets reports fail creates moral hazard — the team takes reckless shortcuts because the manager always catches it

## The Defense

1. **Skin in the game.** The person taking the risk must bear some of the downside.
2. **Counter-metrics.** For every metric you reward, track the cost metric too. See [Goodharts-Law](/patterns/goodharts-law).
3. **Structural constraints over trust.** Don't rely on people to self-regulate when incentives point the other way. See Autonomy-Through-Constraints.

## Related Patterns

- [Incentives-Drive-Behavior](/patterns/incentives-drive-behavior) — the general case. Moral hazard is what happens when incentives reward risk-taking without consequences.
- Managers-Mind — people model your incentive structure better than you do. If you signal that failure has no consequences, they'll act accordingly.
- [Goodharts-Law](/patterns/goodharts-law) — moral hazard is a specific instance of Goodhart's: the metric (risk-adjusted return) gets gamed when consequences are removed.
- Autonomy-Through-Constraints — the design pattern that counters moral hazard in agent systems.
