Scarcity
and urgency.
Scarcity is our habit of wanting something more when there's less of it, and urgency is the time version: less time to decide. Real limits work. Made-up ones are a growing legal risk: in its 2026 Black Friday sweep, the ACCC found about half of 50 retailers made concerning claims, including countdown timers for sales that kept running. Use the limits you genuinely have.
Written by Dan Picken, a marketer applying published research. Last checked 30 October 2026.From Worchel, Lee and Adewole (1975). Ratings were higher again when the jar ran low because others wanted them.
What the
research says.
Evidence: DependsReal scarcity reliably raises desire. Pressure tactics work mostly on people who aren't thinking hard, and fake ones are a growing legal risk.
In a classic study, people rated cookies from a jar of two as more desirable than the same cookies from a jar of ten. They rated them higher again when the jar was low because of demand from other people, not by accident. Why something is scarce matters as much as how scarce it is.
A 2022 meta-analysis pooled 416 results from 131 studies and found scarcity cues generally raise how much people value a product and their intention to buy. The type of scarcity mattered: 'others are buying it' worked best for practical products, limited supply for experiences, and time limits for bigger, more involved purchases.
Not everyone is moved. In research on deal restrictions such as purchase limits and time limits, the restrictions only lifted choice among people low in 'need for cognition', the ones who think less carefully about the deal. Careful buyers, often the ones spending the most, are the least swayed by pressure.
In Australia, fake urgency is a live enforcement target. In September 2026, two retailers paid infringement notices over sale end dates and countdown timers that weren't genuine. From 1 July 2027, new unfair trading practices laws name misleading countdown timers and low-stock cues as examples of manipulative dark patterns.
In your
marketing.
Booking calendars
'Two install slots left before Christmas', straight from your real calendar.
Trades
Product pages
A stock count that is your actual stock, updated automatically, not a number someone typed in.
E-commerce
Events
Real ticket numbers for a set night, and saying so when it's nearly full.
Hospitality
Deadlines
Genuine close dates, like application rounds or end of financial year, stated with the date.
Education
Where it backfires
Timers that reset, sales that never end, 'selling fast' on everything. Buyers learn to ignore it, and the ACCC is watching.
All
Fake urgency,
honest urgency.
Most businesses already have a real limit. Use that instead of inventing one.
| Industry | Fake urgency | Honest urgency |
|---|---|---|
| E-commerce | A countdown that resets at midnight | 'Last 4 in stock', from your live stock count |
| Trades | 'Prices rising soon!' with no date | 'Two install slots left before Christmas', from your real calendar |
| Hospitality | 'Selling fast!' on a half-empty night | 'Last 12 tickets for Saturday's tasting' |
| Education | 'Places limited, enrol now' all year round | 'Applications close 30 September' |
| B2B | 'This offer won't last' | 'Pricing changes on 1 July', with the new price shown |
Try it
Real urgency,
or pressure?
Pick the kind of urgency in your ad or page, then answer five questions honestly. It tells you how it reads, why, and what to use instead.
How it reads
An honest alternative
Based on the ACCC's 2026 Black Friday findings and the unfair trading practices laws starting 1 July 2027. A marketer's check, not legal advice.
Try this
Use a real limit you already have, like a booking calendar or a close date.
It backfires when
The deadline resets, or the 'only 3 left' isn't true.
In my experience
The urgency I see most is the kind nobody believes: a 'sale ends Sunday' banner that has been up since winter. Most businesses already have a real limit they could use instead, like a booking calendar that genuinely fills up, a seasonal cut-off or a price change with a date on it. Real limits are more persuasive, and they don't put anyone at risk.
Test it on
your own buyers.
- 1
Find your real limit
Calendar slots, stock, event capacity, a seasonal cut-off or a price change date. Use the checker above to make sure it's genuine.
- 2
Say why it's limited
Scarcity from demand or a real constraint works better than scarcity with no reason.
- 3
Run it against no urgency
Same page or ad, with and without the limit, at the same time.
- 4
Judge on sales and refunds
Watch enquiries or sales, and also cancellations and complaints. Pressure that brings regret isn't a win.
Questions
people ask.
Are countdown timers legal in Australia?
Yes, if they're genuine. The ACCC has said timers claiming a sale was about to end, when it actually continued, can mislead. If the timer resets, or the same deal comes back straight after, don't use one.
Is 'only 3 left' allowed?
Only if it's true. Under the unfair trading practices laws starting 1 July 2027, misleading low-stock cues are listed as an example of dark patterns, and false claims can already breach Australian Consumer Law.
Does scarcity marketing actually work?
Generally, yes, when it's real. A meta-analysis of 131 studies found scarcity cues usually raise desire and purchase intention, with the best type depending on the product.
What's changing in July 2027?
New unfair trading practices laws ban conduct that manipulates consumers or unreasonably distorts their decisions. Law firm Allens notes false urgency and high-pressure tactics can count, with penalties up to $100 million or more for companies.
What's the difference between scarcity and urgency?
Scarcity is about quantity: few left. Urgency is about time: not long to decide. Both work for the same reason, and both need to be true.
Does urgency work on careful buyers?
Less. Research on deal restrictions found they mainly swayed people who think less carefully about the deal. For big, considered purchases, a real reason to act beats pressure.
