Distinction Bias is two options seen side-by-side look more different than they are in isolation. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0245, within the Decision family. The core principle: two options seen side-by-side look more different than they are in isolation. 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: two options seen side-by-side look more different than they are in isolation. You can recognize it in the field by its signature: comparison amplifies differences that won't matter later. 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, choice architecture distorts perceived differences. It is amplified whenever choice architecture distorts perceived differences. Inside organizations that shows up as choice architecture distorts perceived differences. 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 each option independently first. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
