Diversification Bias is we choose more variety than we'll actually want when picking for the future all at once. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0247, within the Decision family. The core principle: we choose more variety than we'll actually want when picking for the future all at once. 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 is one of the elements leaders describe as a values gap. It is a payoff gap. The mechanism underneath it is straightforward: we choose more variety than we'll actually want when picking for the future all at once. You can recognize it in the field by its signature: the snack assortment you bought Sunday is the snack assortment you'll regret Wednesday. 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, subscription bundles and feature menus overestimate variety preference. It is amplified whenever subscription bundles and feature menus overestimate variety preference. Inside organizations that shows up as subscription bundles and feature menus overestimate variety preference. 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 sequential choices reveal real preference better than simultaneous ones. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
