Self-Determination Theory is humans need autonomy, competence, and relatedness. It sits in the Biology dimension (BIO) of the Human Behavior Taxonomy™ as element HBT-BIO-0072, within the Motivation family. The core principle: humans need autonomy, competence, and relatedness. 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: pay matters. Pay alone never enough. 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, frame motivation design around all three needs. It is amplified whenever frame motivation design around all three needs. Inside organizations that shows up as frame motivation design around all three needs. 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 audit work systems for autonomy, competence, and relatedness deficits. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
