Evaluating
Scarcity Bias
Scarcity speeds up decision-making by triggering fear of missing out, raising expectations that can lead to post-purchase disappointment if the experience falls short.
For Example
Luxury brands like Hermès use controlled scarcity, producing only a limited number of Birkin bags each year. This intentional limitation drives desirability and status signaling, making customers willing to join long waitlists or pay extreme resale prices. In a different industry, hotel booking sites create urgency by displaying “Only 2 rooms left at this price,” pushing customers to act quickly before availability runs out.

Scarcity Bias is the tendency to perceive limited resources—whether products, time, or opportunities—as more valuable simply because they are scarce. Rooted in evolutionary psychology, this bias exists because, historically, rare resources were often essential to survival. Today, brands and businesses leverage scarcity to drive urgency, create exclusivity, and amplify desirability. Customer Experience (CX) strategies often deploy scarcity-based messaging such as “Only 3 left!” or “Limited-time offer,” which increases purchase likelihood. But scarcity can also backfire—excessive pressure can lead to customer frustration, distrust, or impulsive regret. Ethical use of scarcity in CX involves balancing urgency with transparency, ensuring the customer experience remains positive rather than manipulative.
Scarcity Increases Perceived Value of Identical Items
In a famous study, Worchel et al. (1975) gave participants two identical jars of cookies. One jar contained 10 cookies, the other only 2. Participants rated the cookies from the nearly empty jar as more desirable, even though they were exactly the same. This confirmed that scarcity increases perceived value—people instinctively prefer things that seem harder to get. Meaning for CX: Customers often overvalue products or experiences simply because they seem exclusive. Limited-edition drops, invite-only memberships, and countdown timers all work by triggering this bias. However, if overused or artificially created too often, scarcity tactics can lead to distrust. Brands should ensure their use of scarcity aligns with genuine value and transparency.
The Impact of Time Scarcity on Advertisement Appeal Among University Students
In another study, 100 university undergraduates were presented with two advertisements. One advertisement utilized time scarcity, while the other did not employ any scarcity tactics. Participants were then asked to evaluate both advertisements by filling out a form. The results indicated that the time scarcity advertisement was perceived as more appealing than the non-scarcity advertisement. This finding highlights the effectiveness of time scarcity in enhancing the appeal of promotional content.
Urgency Messaging and Purchase Decisions
A 2013 study by Aggarwal et al. examined how scarcity messaging influences consumer urgency. Participants browsing an online store were shown two versions of a product listing—one with neutral messaging and one with a scarcity-driven message such as “Only 3 left in stock!” The scarcity messaging significantly increased purchase conversion rates. However, when scarcity was used repeatedly, it triggered skepticism and reduced trust over time. Meaning for CX: This demonstrates that scarcity works best when it feels authentic. Customers respond positively to genuine urgency but can detect artificial scarcity, leading to negative brand perception. In CX, scarcity should be used selectively—seasonal products, exclusive launches, or limited-edition collections—to maintain credibility.
Create Anticipation for Limited Availability
Before customers even realize they want something, scarcity can be used to spark curiosity. Exclusive pre-launch teasers (e.g., “Something big is coming soon”) create a sense of anticipation, making potential customers pay attention early. In CX, brands can build desire before launching by hinting at exclusivity.
Make Scarcity Part of the Brand Story
During the awareness phase, brands can position scarcity as a core part of their identity. Rolex doesn’t just sell watches—it sells “precision in limited numbers.” Brands that use scarcity in their branding (e.g., “crafted in small batches”) create desirability even before the product is fully considered.
Use Real-Time Urgency to Reduce Hesitation
Customers in the comparison stage often delay decisions. Scarcity nudges them to act by showing real-time limitations (e.g., “5 seats left at this price”). However, CX must balance urgency with trust—too much scarcity pressure can cause decision paralysis or brand skepticism.
Create a Sense of “Special Discovery”
At this stage, scarcity should feel rewarding, not pressured. Think about a hidden sale only for app users, or personalized recommendations with “Exclusive to you” labels. CX teams can gamify discovery, making limited opportunities feel like a rare find rather than a forced rush.
Leverage Social Scarcity to Drive FOMO
Customers researching brands respond strongly to social scarcity—if they see others accessing something they can’t, demand rises. Showing testimonials like “Only 100 members get access” or “Join the inner circle” makes a product feel like a privilege rather than just a purchase.
Reinforce Decision by Reminding of Limited Access
Once customers are close to buying, scarcity bias helps validate their choice. Limited-time bonuses (“Order today and get early access”) increase confidence and reduce hesitation.
Turn Buying Into an Exclusive Experience
Scarcity doesn’t end at checkout. Make customers feel special—numbered receipts, “You got one of the last 50,” or unique packaging can make a purchase feel premium.
Manage Expectations to Prevent Post-Purchase Regret
Scarcity doesn’t just influence purchase behavior—it lingers in the customer’s mind after the transaction. When customers acquire something that was marketed as rare or exclusive, they often expect it to deliver above-average satisfaction. If the product or experience fails to meet these expectations, regret or disappointment can set in.
For example, if a hotel advertises a “last available luxury suite,” but the guest finds it to be underwhelming, the disappointment will be greater than if they had booked it without urgency-based messaging. The same applies to limited-edition products—when customers feel pressured to act fast, they may later second-guess their decision or find minor flaws more frustrating.
Customer Experience Challenges
Typical challenges in CX where the bias can be used
- Control: Scarcity marketing can make customers feel like they lack control over their purchase decision, leading to hesitation or anxiety. Managing this through thoughtful CX design is crucial.
- Motivation: Urgency messaging can increase short-term motivation, but brands must ensure customers remain engaged after the purchase. If scarcity is overused, it can create fatigue.
- Confidence: While scarcity can drive immediate action, it can also leave customers feeling unsure after they buy. Reinforcing their decision is key to sustaining confidence.
- Selection: When scarcity limits available options, customers might feel restricted in their choices. A good CX strategy balances urgency with the feeling of autonomy.
- Risk: Customers may perceive high risk when making a purchase under pressure. CX teams must minimize this by offering strong guarantees, easy returns, or post-purchase support.
Customer Experience Pillars
Renascence CX pillars where it can be applied most efficiently
- Expectations: Scarcity raises expectations—customers assume exclusive products or experiences will be superior. Brands must ensure reality aligns with the anticipation.
- Emotions: The urgency created by scarcity triggers excitement and anxiety, shaping the emotional landscape of the customer journey. CX teams must guide this toward positive emotional reinforcement post-purchase.
- Integrity: Overuse of artificial scarcity (e.g., false “only 3 left” alerts) damages trust. CX strategies should be transparent and ethical to avoid long-term reputational damage.
- Personalization: Customers respond better to scarcity when it feels tailored to them (e.g., “Your exclusive early access” vs. “Limited availability for everyone”). This ensures urgency feels rewarding, not manipulative.
- Resolution: Scarcity-driven decisions need post-purchase validation—otherwise, regret can erode loyalty. Follow-up messaging should affirm that the customer made a smart, valuable choice.
Customer Experience Interfaces
Interfaces & touchpoints where it can be applied most efficiently
- Digital: Countdown timers, limited-stock labels, and waitlists can increase engagement—but should not be overused.
- Promo: Exclusive early access, VIP-only product drops, and members-only deals reinforce perceived value.
- Shelf: Highlighting "Only X left" signage can boost urgency in physical stores.
- Voice: Customer service agents can emphasize limited availability to drive urgency (“We only have a few left at this price”).
- Product: Limited editions, numbered releases, or exclusive packaging create scarcity-driven desirability.
Renascence Tip
Scarcity is one of the most powerful tools in customer psychology, but it must be handled carefully. When used authentically, it increases desirability, speeds decision-making, and enhances perceived value. However, excessive or artificial scarcity damages trust—if customers feel manipulated, they may disengage permanently. The best use of scarcity in CX is when it aligns with real limitations (e.g., seasonal items, special collaborations, handmade goods). Ethical scarcity enhances customer experience, while artificial scarcity erodes it.
