Scarcity is things feel more valuable when supply or time is limited. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0595, within the Social family. The core principle: things feel more valuable when supply or time is limited. 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 Cognition dimension — how do we think?. You can recognize it in the field by its signature: only 3 left — and now there are two reasons to buy. 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, 'Waitlist only' framing accelerates sign-ups regardless of fit. It is amplified whenever artificial scarcity props up margins but erodes trust on repeat exposure. Inside organizations that shows up as artificial scarcity props up margins but erodes trust on repeat exposure. 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 ask: would I still want this if supply were infinite?. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
