A school pays kids for good grades. Students cheat to get grades. The incentive (payment) created the problem (cheating), making education worse.
The Original Discovery
British colonial India offered bounty for cobra skins to reduce cobra population. People started breeding cobras to collect bounties. When the program was canceled, breeders released the cobras. The problem worsened. Now synonymous with perverse incentives.
How It Works in Real Life
The Cobra Effect isn’t a rare phenomenon—it’s everywhere once you start looking:
- A company tries to reduce bugs by penalizing programmers for bugs shipped. Programmers hide bugs instead of reporting them. The problem gets worse (hidden bugs are harder to fix).
- A city wants to reduce homeless population, so they arrest homeless people. The penalty is jail, creating a criminal record. With a record, homelessness becomes harder to escape.
- A company tries to increase efficiency by measuring lines of code written. Developers write inefficient code to hit metrics. Code quality plummets.
Why This Matters to You
The Cobra Effect is why well-intentioned incentive systems backfire. When designing incentives, ask: ‘How could someone game this system?’ Perverse incentives are almost always present if you look for them. The best incentives align what you’re paying for with what you actually want. A school should pay for learning, not grades. A company should reward quality, not volume. Design incentives carefully. Bad incentives are worse than no incentives.
