Outcome-Only Evaluation is judging only results ignores ethics of process and rewards shortcuts that look like wins. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0198, within the Universal Pattern Perverse Pattern family. The core principle: judging only results ignores ethics of process and rewards shortcuts that look like wins. 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 only results ignores ethics of process and rewards shortcuts that look like wins. You can recognize it in the field by its signature: if the only question is 'did it work,' someone will cheat to make it work. Every element in the Incentives 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, process integrity is part of outcome quality. It is amplified whenever process integrity is part of outcome quality. Inside organizations that shows up as process integrity is part of outcome quality. 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 process audits. How-we-won reviews. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
