Argument from Repetition (Argumentum ad Nauseam) is saying it enough times until it sounds true. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0062, within the Relevance Fallacy family. The core principle: saying it enough times until it sounds true. 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: saying it enough times until it sounds true. You can recognize it in the field by its signature: repetition is a strategy. 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, strategic narratives that win by frequency, not by quality. It is amplified whenever strategic narratives that win by frequency, not by quality. Inside organizations that shows up as strategic narratives that win by frequency, not by 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 make the desired behavior observable, remove whatever currently pays for its opposite, and attach the reward to the behavior rather than to the noisy outcome downstream of it. 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.
