Intrinsic Motivation is doing something because the doing is the reward. It sits in the Biology dimension (BIO) of the Human Behavior Taxonomy™ as element HBT-BIO-0050, within the Motivation family. The core principle: doing something because the doing is the reward. 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 operates in the Biology dimension — what does the body contribute?. You can recognize it in the field by its signature: the best people do their best work for reasons you can't pay for. Every element in the Biology 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, comp design that protects intrinsic motivation. It is amplified whenever comp design that protects intrinsic motivation. Inside organizations that shows up as comp design that protects intrinsic motivation. 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 don't replace intrinsic with extrinsic. You'll lose both. 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.
