Availability Heuristic is we judge frequency by how easily examples come to mind. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0077, within the Memory Bias family. The core principle: we judge frequency by how easily examples come to mind. 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: we judge frequency by how easily examples come to mind. You can recognize it in the field by its signature: vivid beats true. Recent beats important. 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 summaries that lead with anecdotes warp executive judgment by design. It is amplified whenever strategy overweights the loud and recent; under-weights the silent base rate. Inside organizations that shows up as strategy overweights the loud and recent; under-weights the silent base rate. 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 require base rates in every memo before any narrative. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
