Cognitive Bias is systematic deviations from rationality in judgment. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0154, within the Reasoning family. The core principle: systematic deviations from rationality in judgment. 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: systematic deviations from rationality in judgment. You can recognize it in the field by its signature: biases aren't bugs in thinking — they're features that misfire. 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, decision systems either account for bias or are corrupted by it. It is amplified whenever decision systems either account for bias or are corrupted by it. Inside organizations that shows up as decision systems either account for bias or are corrupted by it. 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 build process — not willpower — to counter known biases. 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.
