Evolution is variation, selection, retention — the engine of cumulative change. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0281, within the Systems family. The core principle: variation, selection, retention — the engine of cumulative change. 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
This is one of the elements leaders describe as a values gap. It is a payoff gap. The mechanism underneath it is straightforward: variation, selection, retention — the engine of cumulative change. You can recognize it in the field by its signature: the mechanism that produced you also produces obsolescence. 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, strategy is evolutionary design: variation, selection, retention. It is amplified whenever strategy is evolutionary design: variation, selection, retention. Inside organizations that shows up as strategy is evolutionary design: variation, selection, retention. 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 engineer all three. Don't just generate ideas — select and retain them. 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.
