Tragedy of the Commons is shared resources get over-consumed by individual rational actors. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0676, within the Systems family. The core principle: shared resources get over-consumed by individual rational actors. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Original analysis from The Incentives Lab — how this element behaves inside real payoff structures.
Why this element matters to incentive design
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: shared resources get over-consumed by individual rational actors. You can recognize it in the field by its signature: everyone took a little extra. Nothing's left. Every element in the Cognition dimension changes the perceived payoff of an action before the action happens, which is exactly where incentive design has leverage.
How it gets exploited
Left undesigned, most cross-functional dysfunction is a commons tragedy. It is amplified whenever most cross-functional dysfunction is a commons tragedy. Inside organizations that shows up as most cross-functional dysfunction is a commons tragedy. The pattern is the same one Goodhart's Law describes: the measurable proxy attracts the effort, and the purpose behind it quietly loses funding.
How the Lab designs around it
The redesign move is to assign clear ownership. Price the commons. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
