Objective Function is what the model is actually optimizing. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0191, within the Alignment family. The core principle: what the model is actually optimizing. 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 element is common enough to feel like human nature and specific enough to be engineered around. The mechanism underneath it operates in the Incentives dimension — what makes behavior more or less likely?. You can recognize it in the field by its signature: models do exactly what they're told. The damage lives in the spec. Every element in the Incentives 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, strategy is downstream of objective design. It is amplified whenever strategy is downstream of objective design. Inside organizations that shows up as strategy is downstream of objective design. 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 treat objective function definition as the most important AI design decision. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
