CONCEPT
The Tragedy of the Commons
Garrett Hardin's 1968 parable that shared resources face inevitable destruction through rational self-interest — the framework Ostrom spent four decades empirically dismantling, and the intellectual default that continues to structure the AI governance debate.
Hardin's 1968 Science essay argued that any resource held in common would be inevitably destroyed by the rational self-interest of its users. Each herder, calculating that the benefit of adding one more cow to the common pasture accrued entirely to himself while the cost of overgrazing was distributed among all herders, would add cow after cow until the pasture was ruined. The parable became policy — privatization for fisheries, nationalization of forests, top-down regulatory regimes — and displaced the need for evidence with the force of its logic.

Ostrom's empirical challenge demonstrated that Hardin's argument held only under a specific set of institutional conditions: the absence of communication, the inability to make binding agreements, the lack of monitoring and enforcement mechanisms. When herders could talk to each other, agree on stocking limits, watch each other's behavior, and impose graduated penalties on violators, the predicted outcome did not occur.
