Mere Exposure Effect is familiarity breeds approval. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0468, within the Perception Bias family. The core principle: familiarity breeds approval. 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
When this element shows up in a diagnostic, the instinct is to train people out of it. Training rarely moves it. The mechanism underneath it is straightforward: familiarity breeds approval. You can recognize it in the field by its signature: the fifteenth time you hear the slogan, it starts sounding profound. 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, aI features rejected on day one get accepted by month six — same features. It is amplified whenever bad ideas survive on familiarity alone. Inside organizations that shows up as bad ideas survive on familiarity alone. 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 re-evaluate familiar claims with fresh eyes. Bring in outsiders. 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.
