Incentive Drift is reward systems slowly diverge from the outcomes they were meant to drive. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0393, within the Incentives family. The core principle: reward systems slowly diverge from the outcomes they were meant to drive. 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
The mistake with this element is treating it as irrationality. It is almost always a rational response to a payoff nobody wrote down. The mechanism underneath it operates in the Cognition dimension — how do we think?. You can recognize it in the field by its signature: today's KPI is tomorrow's perverse incentive in a suit. 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, reward models drift as the world they describe shifts. It is amplified whenever most strategy decay is unmeasured incentive drift. Inside organizations that shows up as most strategy decay is unmeasured incentive drift. 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 re-baseline incentives against outcomes every 6–12 months. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
