In one paragraph

Expected Utility (vs. Expected Value) is decisions optimize utility, not value. It sits in the Identity dimension (IDN) of the Human Behavior Taxonomy™ as element HBT-IDN-0010, within the Decision family. The core principle: decisions optimize utility, not value. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Lab Commentary

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: decisions optimize utility, not value. You can recognize it in the field by its signature: $1M to a billionaire is not $1M to a startup. 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, why two rational actors can disagree on the same EV. It is amplified whenever why two rational actors can disagree on the same EV. Inside organizations that shows up as why two rational actors can disagree on the same EV. 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 factor utility curves into decision frameworks for big bets. The test of any redesign here is simple: after the change, can you name what the organization is now doing less of? If not, the payoff structure did not actually move.
