Real Scarcity

Displaying genuine inventory or capacity limitations. 'Only 3 left in stock', 'Last room at this price', '2 seats remaining' — when true. Real scarcity triggers loss aversion more powerfully than most other persuasion techniques because the limit is verifiable and the consequence of delay is clear. Distinct from manufactured scarcity, which is a dark pattern with legal risk in most markets.

When it works

Physical inventory genuinely running low. Event seats or course cohorts with hard capacity limits. Hotel rooms and flights. Limited-edition product runs with a real production ceiling. Only effective when the user is already in consideration — scarcity accelerates a decision, it doesn't create desire.

When it backfires

When scarcity is easily disproven (user refreshes and the count resets or increases). In B2B enterprise sales where procurement timelines cannot be compressed. When item is low-consideration — pressure creates annoyance, not purchase. When the scarcity threshold is set too high to be credible.
