Extrinsic Incentives Bias is believing others are motivated by extrinsic rewards while we are motivated intrinsically. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0117, within the Social family. The core principle: believing others are motivated by extrinsic rewards while we are motivated intrinsically. 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
When this element shows up in a diagnostic, the instinct is to train people out of it. Training rarely moves it. The mechanism underneath it is straightforward: believing others are motivated by extrinsic rewards while we are motivated intrinsically. You can recognize it in the field by its signature: 'They want money. I want meaning.'. 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, incentive design built on this bias misses what actually motivates. It is amplified whenever incentive design built on this bias misses what actually motivates. Inside organizations that shows up as incentive design built on this bias misses what actually motivates. 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 survey actual motivation. Don't assume the asymmetry. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
