Frequency Illusion is after noticing something, we start seeing it everywhere. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0333, within the Reasoning family. The core principle: after noticing something, we start seeing it everywhere. 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
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: after noticing something, we start seeing it everywhere. You can recognize it in the field by its signature: you buy a blue car and suddenly every car is blue. 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, recency and attention create the illusion of a trend. It is amplified whenever recency and attention create the illusion of a trend. Inside organizations that shows up as recency and attention create the illusion of a trend. 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 track actual frequency, not just perceived frequency. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
