Representativeness Heuristic is we judge probability by how similar an event is to a prototype. It sits in the Time dimension (TIM) of the Human Behavior Taxonomy™ as element HBT-TIM-0010, within the Probability family. The core principle: we judge probability by how similar an event is to a prototype. 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: we judge probability by how similar an event is to a prototype. You can recognize it in the field by its signature: it looks like a duck, so we assume it is a duck. Every element in the Time 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, stereotypes and prototypes drive hiring and investment decisions. It is amplified whenever stereotypes and prototypes drive hiring and investment decisions. Inside organizations that shows up as stereotypes and prototypes drive hiring and investment decisions. 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 look for base rates and direct evidence, not just resemblance. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
