CD6 Scarcity & Impatience
The drive to want something because it is rare, exclusive or not available yet. Chou rates it the most volatile quadrant, Black Hat and left-brain: strong for launch bursts and closing moments, weak for long engagement, and it drives obsession rather than enjoyment. Goals that look impossible flip it into dismissal.
Plain label: wanting what you can't have yetAlso known as: Scarcity & Impatience, Core Drive 6
Essence
We want what we cannot have right now CD6 (Actionable Gamification Ch.10, p.230). Restricted access signals value, a limit makes an action more attractive, and a dangled reward builds desire with each exposure. Scarcity only works if people know the reward exists, and the path to it must look hard but possible.
Position
- Hat: Black. Brain side: Left.
- Strongest phases: exclusivity and qualifying steps in Discovery and Onboarding, progressive disclosure in Onboarding, and the closing moment in monetization. A mature product that already engages does not need more of it.
Watch-outs
- Self-denial: an unattainable goal makes people belittle it and walk away.
- CD6 with CD7 becomes obsessive; CD6 with CD8 creates extreme urgency.
- Paying to play less: when revenue comes mostly from people paying to skip waits, the core may not be fun.
- Faked scarcity (outages, stock, queues) destroys trust and invites regulators.
