Productivity Mirage is individual speed gains hide collective quality decline. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0217, within the Risk family. The core principle: individual speed gains hide collective quality decline. 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 operates in the Incentives dimension — what makes behavior more or less likely?. You can recognize it in the field by its signature: everyone moves faster. The product gets worse. 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, local optimization producing global degradation. It is amplified whenever local optimization producing global degradation. Inside organizations that shows up as local optimization producing global degradation. 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 measure outcomes, not throughput. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
