Association Fallacy is assuming qualities of one thing transfer to another because they are associated. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0066, within the Reasoning family. The core principle: assuming qualities of one thing transfer to another because they are associated. 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: assuming qualities of one thing transfer to another because they are associated. You can recognize it in the field by its signature: guilt by association, dressed up as logic. 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, resumes are judged by the companies listed, not the results delivered. It is amplified whenever resumes are judged by the companies listed, not the results delivered. Inside organizations that shows up as resumes are judged by the companies listed, not the results delivered. 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 based on direct evidence, not symbolic connections. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
