| ### Segment 1 — The Hook > **In colonial Delhi, British administrators posted notices offering a cash payment for every cobra turned in dead, believing a simple financial reward would clear the city of a persistent danger. Within months, the number of snakes presented for payment rose sharply, yet reports of cobra sightings and bites in the streets did not fall. When the government ended the payments, residents who had been raising the snakes in their homes and courtyards released thousands of live cobras back into the city, leaving the snake population larger than it had been before the policy began.** ### Segment 2 — The Good Intention > **The British colonial administration in Delhi confronted a practical problem of public safety in a densely populated city where cobras were common. Venomous snakes posed a real threat to residents and to the growing number of British officials and their families living in the area. Administrators drew on earlier experiences with bounty systems used in other parts of the empire to control wolves, jackals, and rats, systems that had appeared to reduce animal numbers without requiring large teams of government hunters. Offering a modest sum for each dead cobra seemed like an efficient way to enlist local residents in the effort while keeping costs low and avoiding the need to expand the colonial bureaucracy. At the time, the approach aligned with prevailing ideas about using market-like incentives to achieve administrative goals in territories where direct control was limited and resources were stretched.** ### Segment 3 — The Implementation The bounty program was introduced through local government offices in Delhi, where residents could bring dead cobras to designated collection points and receive payment on the spot. Early records of the scheme show a steady stream of submissions in the first weeks and months, which officials interpreted as evidence that the incentive was working and that the local snake population was being reduced. British administrators described the policy in internal correspondence as a low-cost success that harnessed private initiative for a public purpose. No widespread skepticism appears in surviving accounts from the period; the method fit comfortably within the administrative toolkit of the time, which often relied on small payments to shape behavior in areas such as sanitation and pest control. The program operated for a period long enough for residents to observe the payment process and calculate its potential returns. ### Segment 4 — The Unintended Consequences Residents quickly recognized that the bounty paid the same amount whether the cobra had been caught in the wild or raised from a clutch of eggs in a backyard enclosure. Breeding the snakes required little capital beyond a few breeding pairs and basic care, and it produced a reliable supply of animals that could be killed and presented for payment. As more people entered this activity, the number of cobras turned in for the reward continued to climb even as the actual wild population may have stabilized or begun to grow from escaped or released animals. When colonial officials noticed the pattern and concluded that the payments were sustaining rather than reducing the snake numbers, they cancelled the bounty. At that point, individuals who had invested in breeding operations faced a sudden loss of income and a large stock of live animals with no remaining value. Rather than incur the cost of maintaining or destroying the snakes, many released them into the streets and surrounding areas. The result was a sharp increase in the cobra population beyond the level that had existed before the program started. The causal mechanism was straightforward: the incentive rewarded the production of dead snakes, not the permanent removal of snakes from the environment, and it created an artificial market that responded to the reward rather than to the underlying ecological problem. Second-order effects included greater risk of bites in neighborhoods where released snakes established themselves, and the loss of any initial reduction in encounters that the early phase of the program may have achieved. The episode also illustrated how quickly local economic actors could adapt to a new payment rule once they understood its mechanics. ### Segment 5 — The Aftermath Once the increase in snakes became evident, the colonial government discontinued the bounty payments and did not attempt a revised version of the same approach. The released animals contributed to a temporary worsening of the situation, after which snake numbers presumably returned to a level determined by natural factors and ongoing informal control efforts by residents. No further large-scale bounty programs for cobras were recorded in Delhi. The story of the policy circulated in administrative and later economic writing as an example of an incentive that produced the opposite of its intended result. In the twentieth century, the episode was cited in discussions of perverse incentives, and economist Horst Siebert later gave it the name “Cobra Effect” in his 2001 book on unintended consequences of policy. Today the term is used in policy analysis to describe situations in which a reward for a measurable output encourages the creation of that output rather than the solution of the underlying problem. ### Segment 6 — The Lesson The Delhi cobra program shows that incentive structures will be interpreted by participants in ways that maximize their own returns, even when those returns diverge from the original public goal. A payment tied to the count of dead animals created a supply response instead of a reduction in the living population. The case also demonstrates that complex biological and social systems can absorb simple interventions and redirect them toward outcomes that were never anticipated by the designers. Modern parallels appear in areas such as performance targets in public services or subsidies for certain environmental behaviors, where the measurable activity can expand without delivering the deeper result. When designing rewards or penalties, it remains useful to ask what new behaviors the rule itself will reward once people have time to adapt to it. |
