Theory of Mind is modeling what others think, want, and will do. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0668, within the Social family. The core principle: modeling what others think, want, and will do. 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: modeling what others think, want, and will do. You can recognize it in the field by its signature: most failed plans assumed the other side didn't have a strategy. 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, stakeholder management. It is amplified whenever stakeholder management. Inside organizations that shows up as stakeholder management. 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 map the room before walking into it. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
