Fast and Frugal Heuristics is gigerenzer's view: simple heuristics that exploit the structure of the environment can beat complex models. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0307, within the Reasoning family. The core principle: gigerenzer's view: simple heuristics that exploit the structure of the environment can beat complex models. 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
Most organizations meet this element as a personnel problem. It is not one. The mechanism underneath it is straightforward: gigerenzer's view: simple heuristics that exploit the structure of the environment can beat complex models. You can recognize it in the field by its signature: less information, better decision — under the right conditions. 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, sometimes the right move is fewer inputs, not more. It is amplified whenever sometimes the right move is fewer inputs, not more. Inside organizations that shows up as sometimes the right move is fewer inputs, not more. 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 match the heuristic to the environment — don't bolt complexity on for theater. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
