Availability Cascade is a story repeats until it becomes obviously true. It sits in the Identity dimension (IDN) of the Human Behavior Taxonomy™ as element HBT-IDN-0001, within the Belief Bias family. The core principle: a story repeats until it becomes obviously 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
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: a story repeats until it becomes obviously true. You can recognize it in the field by its signature: said enough times, an anecdote becomes a strategy. Every element in the Identity 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, hype-cycle narratives become budget allocations. It is amplified whenever strategy follows whatever narrative had the best PR cycle. Inside organizations that shows up as strategy follows whatever narrative had the best PR cycle. 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 demand the underlying base rate every time the anecdote surfaces. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
