Scarcity
The harder an opportunity is to get, the more people tend to value it, for two reasons: hard-to-get things are usually better, and losing access threatens a freedom (reactance). Scarcity is strongest when it is new and caused by demand. It raises wanting, not how good the thing actually is.
Plain label: less available seems more valuableAlso known as: scarcity, reactance, loss aversion, urgency, exclusivity
Two sources INF-M-64 (Influence Ch.7, p.183) (Ch.7, pp.183-184): a quality shortcut and reactance.
Reactance INF-M-65 (Influence Ch.7, p.184) (Ch.7, pp.184-189). Restrict a freedom and people want it more, then credit it with better qualities. Losing an established freedom provokes the strongest reaction (in-t-sc-13, in-t-sc-19).
Optimal conditions INF-M-68 (Influence Ch.7, p.193) (Ch.7, pp.193-200)
| Condition | Effect |
|---|---|
| Scarce vs abundant | Scarce rated more desirable |
| Newly scarce vs always scarce | Newly scarce rated higher |
| Scarce from demand vs by mistake | Demand-caused rated highest |
| Taste | Unchanged in every condition |
Forms. Limited numbers and deadlines (Ch.7, pp.180-183), see in-t-sc-01 and in-t-sc-03; potential loss (Ch.7, p.179), see in-t-sc-08; exclusive information (Ch.7, pp.192-193); brief open access (Ch.7, pp.178-179), see in-t-sc-24.
The defense (Ch.7, pp.199-203). Treat the rush as a signal to slow down, and ask whether you want to own the thing or to use it.
In a product [S]. Real, scoped, live scarcity only, with wanting and experienced value read side by side (INF-K-44).
