You’re booking a hotel in Goa for a long weekend. Two rooms look almost the same, both around ₹4,000 a night. You’re in no hurry. You read the reviews, then the photos, then the reviews again.
Then a small red line appears under one of them: Only 2 rooms left at this price.
You book it within a minute.
The room didn’t get any better. It just got harder to have.
What’s going on
This is scarcity: we value something more when it seems rare, limited or about to run out. Psychologist Robert Cialdini made it one of the six principles of influence in his 1984 book Influence.
The neatest test came earlier. In 1975, Stephen Worchel, Jerry Lee and Akanbi Adewole asked 134 students to taste and rate a chocolate chip cookie. For some, the cookie came from a jar of ten. For others, from a jar of two. Same cookies. The ones from the jar of two were rated more desirable, and worth more money.
Here’s the strange part. The cookies scored best when the jar dropped from ten to two in front of the students, because other people had eaten more than expected. Scarcity pulls hardest when it comes from other people wanting it.
Think of the last samosa
A plate of samosas goes round the table. Nobody rushes. Then there’s one left, and suddenly everyone has noticed it.
It’s no tastier than the others were. But taking it now means someone else can’t. We don’t want the thing so much as we don’t want to miss it.
Where you’ll spot it
- Tatkal tickets. Booking opens at 10 a.m. a day before the journey. People sit ready at 9:59, because the seats can go in minutes.
- “Only 2 left” in red. On shopping and booking apps, a small number often does more work than a big discount.
- Flash sales. In 2014, Xiaomi sold 40,000 Redmi 1S phones on Flipkart in about four seconds. Each sell-out made the news, and the news made the next sale busier.
The catch
Scarcity only works while people believe it. A countdown that restarts every time you reload the page teaches buyers to ignore you. India’s consumer regulator now lists false urgency among the 13 dark patterns it banned in 2023.
How to use it, carefully
If you’re selling, say so when something really is limited: a small batch, a fixed number of seats, a real last date. Honest scarcity helps people decide. Fake scarcity spends your trust.
If you’re buying, ask one question: if there were a hundred left, would I still want this at this price? If not, it’s the countdown you want, not the thing.
Running out never made anything better. It only makes us decide faster.
