Alex: The story goes that in Delhi, India, under British rule, the city had a cobra problem. Too many venomous snakes. So the government offered a bounty. Bring in a dead cobra, get cash.
Jordan: It works. Dead cobras pile up. The streets get safer. Success.
Alex: Until someone realizes something. Cobras are worth money dead. So why not make more cobras? People start breeding them in their basements.
Jordan: In the story, the bounty was cancelled overnight, and the breeders released their snakes. And all the breeders release their now-worthless cobras into the wild. More cobras than when they started.
Alex: Welcome to Incentives, Decoded. I am Alex.
Jordan: And I am Jordan. This is chapter fourteen, The Cobra Effect. Last time, you learned Goodhart's Law, how measuring a thing destroys the thing. Today, we go further. Sometimes incentives do not just get gamed. They create the exact problem they were trying to solve.
Alex: The cobra effect is when the solution makes the problem worse. And it happens because incentives do not just change behavior at the margin. They create entirely new games.
Jordan: This is the chapter about second-order thinking. The first order is obvious. The second order is where the cobras live.
Alex: The cobra story is not a one-off. It is a pattern.
Jordan: And this one is documented. Vietnam, French colonial era. Rat bounty. Bring in a rat tail, get paid. Soon the streets are full of tailless rats. People were cutting off tails and releasing the rats to breed more tails.
Alex: Same logic. The incentive rewards the evidence of the problem, not the solution. So people manufacture evidence. The tail is not the rat. The dead cobra is not fewer cobras.
Jordan: Modern version? Companies that pay bug bounties sometimes get flooded with trivial bugs, or worse, employees who quietly introduce bugs to fix them later. The incentive creates the supply it was meant to destroy.
Alex: Here is the key insight. People do not just respond to incentives. They innovate around them. Give a smart human a reward, and they will find the cheapest path to it. That path is almost never the one you intended.
Jordan: Why does this keep happening? Because planners think first-order. They see problem, apply incentive, expect solution.
Alex: But humans think in second-order. They see incentive, ask how do I maximize this, and invent a move the planner never imagined. The planner plays checkers. The people play chess.
Jordan: The deeper issue is that incentives are always incomplete. You cannot specify every behavior. You reward dead cobras, but you cannot reward not breeding cobras, because you cannot observe it. Every incentive has a blind spot, and human creativity lives in blind spots.
Alex: This is why the cobra effect is the hardest incentive trap to avoid. Goodhart's Law is about gaming a metric. The cobra effect is about the metric creating a new industry. It is Goodhart's Law with entrepreneurship.
Jordan: And it is not just governments. Every company, every parent, every person who has ever set an incentive has created cobras. The question is whether you noticed.
Alex: Where have your incentives backfired?
Jordan: The cheat day that became cheat week. You rewarded yourself for dieting, and the reward ate the diet. The bonus for finishing early that made everyone cut corners. The kids' allowance for grades that made them cheat on the test.
Alex: Think about your own rules. The phone limit you bypass. The budget category you borrow from. Every personal system you have gamed is a tiny cobra farm.
Jordan: And here is the uncomfortable one. What incentives do you create for others? The employee of the month that made everyone hate the winner. The praise for being busy that made everyone look busy instead of being productive.
Alex: We are all cobra farmers. We just do not like to admit where the snakes are.
Jordan: So here is the move. Think second-order before you incentivize.
Alex: One. Ask the cobra question. Before you launch any incentive, ask: how would a clever, amoral person exploit this? If you can think of a hack in five minutes, someone will find it in five days. Do this before, not after.
Jordan: Two. Pilot small. Do not roll out the bounty citywide. Try it in one neighborhood, watch what happens, look for the breeders. Small experiments reveal cobras before they scale.
Alex: Three. Reward outcomes, not activities. Do not pay for dead cobras. Pay for fewer snakebites. Do not reward hours worked. Reward problems solved. The closer the reward is to the actual goal, the less room for perverse innovation. And when you spot cobras? Wind the incentive down carefully. The British cancelled abruptly and the breeders released their snakes. Speed of reversal matters, but so does the exit.
Jordan: Every incentive is an invitation to be creative.
Alex: Make sure they get creative in the direction you want.
Jordan: Next time, in chapter fifteen, Tragedy of the Commons, we look at what happens when nobody owns the incentive at all. Shared resources, from office fridges to ocean fish, get drained by everyone and maintained by no one. And the commons usually loses.
Alex: Thanks for listening to Incentives, Decoded, chapter fourteen. Check for cobras.
