Learning Curve is performance improves with practice, but gains slow over time. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0436, within the Learning family. The core principle: performance improves with practice, but gains slow over time. 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
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: performance improves with practice, but gains slow over time. You can recognize it in the field by its signature: you get better fast, then better slowly, then you plateau. 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, training ROI is highest early, then requires different interventions. It is amplified whenever training ROI is highest early, then requires different interventions. Inside organizations that shows up as training ROI is highest early, then requires different interventions. 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 plan for plateau-busting techniques after early gains. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
