Pygmalion Effect is high expectations produce higher performance. It sits in the Social dimension (SOC) of the Human Behavior Taxonomy™ as element HBT-SOC-0024, within the Social Bias family. The core principle: high expectations produce higher performance. 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: high expectations produce higher performance. You can recognize it in the field by its signature: tell people they're A-players and they'll act like A-players. Every element in the Social 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, teams treated as 'AI native' build accordingly. Teams treated as resistant fulfill that, too. It is amplified whenever talent reviews become self-fulfilling prophecies in both directions. Inside organizations that shows up as talent reviews become self-fulfilling prophecies in both directions. 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 your expectations. They're shaping the outcomes you're measuring. The test of any redesign here is simple: after the change, can you name what the organization is now doing less of? If not, the payoff structure did not actually move.
