Coordination Cost is working together has a cost that scales with the number of people. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0192, within the Systems family. The core principle: working together has a cost that scales with the number of people. 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
When this element shows up in a diagnostic, the instinct is to train people out of it. Training rarely moves it. The mechanism underneath it is straightforward: working together has a cost that scales with the number of people. You can recognize it in the field by its signature: every additional person doubles the messages. 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, why headcount isn't always the answer. It is amplified whenever why headcount isn't always the answer. Inside organizations that shows up as why headcount isn't always the answer. 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 compute coordination cost before scaling teams. 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.
