Escalation of Commitment is continuing a failing course of action because of prior investment. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0277, within the Decision family. The core principle: continuing a failing course of action because of prior investment. 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 element is common enough to feel like human nature and specific enough to be engineered around. The mechanism underneath it is straightforward: continuing a failing course of action because of prior investment. You can recognize it in the field by its signature: the deeper the hole, the more we insist on digging. 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 logic is the silent killer of capital allocation. It is amplified whenever sunk cost logic is the silent killer of capital allocation. Inside organizations that shows up as sunk cost logic is the silent killer of capital allocation. 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 set kill criteria before the project begins, not after it struggles. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
