The tactic
False scarcity
False scarcity is designed to make an opportunity, product or service seem more rare, and therefore more valuable than it actually is. This plays on consumers’ fear of missing out and loss aversion, rather than allowing them to buy out of genuine desire.
The flip
Real availability
Honesty about what is actually available, and when something really is limited, the reason why. Invented exclusivity is the part to drop, since an invite-only offer can simply be announced to the people being invited. When quantities are genuinely short, an alternative for the people who miss out.
