Lindy Effect is the longer an idea has survived, the longer it likely will. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0444, within the Probability family. The core principle: the longer an idea has survived, the longer it likely will. 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: the longer an idea has survived, the longer it likely will. You can recognize it in the field by its signature: shakespeare will outlive your favorite podcast. 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, distinguishing fads from durable shifts. It is amplified whenever distinguishing fads from durable shifts. Inside organizations that shows up as distinguishing fads from durable shifts. 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 default skepticism on the new; default attention on the durable. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
