Appeal to Pity is asking for a conclusion based on sympathy rather than logic. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0050, within the Emotion Fallacy family. The core principle: asking for a conclusion based on sympathy rather than logic. 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: asking for a conclusion based on sympathy rather than logic. You can recognize it in the field by its signature: we worked so hard on this. Therefore it deserves funding. 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, sunk cost wearing a different jacket. It is amplified whenever sunk cost wearing a different jacket. Inside organizations that shows up as sunk cost wearing a different jacket. 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 make the desired behavior observable, remove whatever currently pays for its opposite, and attach the reward to the behavior rather than to the noisy outcome downstream of it. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
