Inequity Aversion is distaste for unequal payoffs — including when we'd benefit. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0397, within the Social family. The core principle: distaste for unequal payoffs — including when we'd benefit. 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: distaste for unequal payoffs — including when we'd benefit. You can recognize it in the field by its signature: fairness is a constraint people will pay real money to enforce. 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, visible inequity inside a team predicts disengagement more reliably than absolute pay. It is amplified whenever visible inequity inside a team predicts disengagement more reliably than absolute pay. Inside organizations that shows up as visible inequity inside a team predicts disengagement more reliably than absolute pay. 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 design comp ranges, transparency, and explanations for the inequity-averse human. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
