Churn is the rate at which customers (or employees) leave over a period. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0143, within the Markets family. The core principle: the rate at which customers (or employees) leave over a period. 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
Most organizations meet this element as a personnel problem. It is not one. The mechanism underneath it is straightforward: the rate at which customers (or employees) leave over a period. You can recognize it in the field by its signature: you can't outgrow what you can't keep. 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 growth strategies fail because churn isn't fixed first. It is amplified whenever most growth strategies fail because churn isn't fixed first. Inside organizations that shows up as most growth strategies fail because churn isn't fixed first. 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 plug the bucket before scaling the inflow. The test of any redesign here is simple: after the change, can you name what the organization is now doing less of? If not, the payoff structure did not actually move.
