Outcome Bias is judging a decision by its outcome rather than by the quality of the process. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0508, within the Decision family. The core principle: judging a decision by its outcome rather than by the quality of the process. 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
The mistake with this element is treating it as irrationality. It is almost always a rational response to a payoff nobody wrote down. The mechanism underneath it is straightforward: judging a decision by its outcome rather than by the quality of the process. You can recognize it in the field by its signature: a good result makes a bad decision look genius. 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, outcome bias rewards luck and punishes sound judgment. It is amplified whenever outcome bias rewards luck and punishes sound judgment. Inside organizations that shows up as outcome bias rewards luck and punishes sound judgment. 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 evaluate decisions by the information available at the time. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
