Cobra Problem (Perverse Incentives Historical Example)

The historical example from British colonial India where the government offered bounties for dead cobras to reduce the cobra population—which led people to breed cobras for the bounty income. When the bounty was cancelled, breeders released their now-worthless cobras, making the problem worse than before. The Cobra Problem is the canonical illustration of perverse incentives: well-intentioned interventions that produce the opposite of their intended effect because the incentive structure was designed without considering how rational actors would game it.

When to use it

When designing incentive structures, bounties, bonuses, or reward systems; when existing incentives seem to be producing counterproductive behavior; when Goodhart's Law dynamics are suspected; when evaluating policy proposals that create financial incentives.

How it can help

Before implementing any incentive, ask: 'If people optimized purely for this incentive, what would they do?' If the answer is 'something that defeats the purpose,' you have a cobra problem. The diagnostic: does the incentive reward the behavior you want, or does it reward a proxy that can be gamed? Bounties per dead cobra rewarded cobra production, not cobra reduction. Sales commissions per deal can reward deal volume at the expense of deal quality. The fix: align the incentive with the OUTCOME you want, not with a proxy metric that can be gamed.
