Prospect Theory is people value gains and losses asymmetrically, and judge relative to a reference point. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0558, within the Decision family. The core principle: people value gains and losses asymmetrically, and judge relative to a reference point. 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: people value gains and losses asymmetrically, and judge relative to a reference point. You can recognize it in the field by its signature: we are not rational calculators. We are reference-point refugees. 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, framing and reference points drive employee and customer behavior. It is amplified whenever framing and reference points drive employee and customer behavior. Inside organizations that shows up as framing and reference points drive employee and customer behavior. 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 choices around reference points that serve long-term goals. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
