The Decoy Effect in Marketing: Description, Psychology, and Examples
The Decoy Effect is a behavioural bias where the presence of a third, less attractive option influences customers to choose a specific alternative. It works psychologically by manipulating perception of value and making one option appear clearly superior.
In this guide, we’ll explain how it works, why it’s effective, and show real-world marketing examples that use it to increase conversions and the value of those conversions.
Ever wondered how coffee shops convince you to buy the largest drink size? Or why subscription services seem to have that perfect middle option that just feels right? These aren’t coincidences—they’re careful applications of the Decoy Effect, one of the most powerful psychological tools in modern marketing.
What Is The Decoy Effect?
The Decoy Effect (also known as the attraction effect or asymmetric dominance effect) occurs when adding a strategically inferior third option influences preferences between two original options. The “decoy” is asymmetrically dominated—meaning it’s completely inferior to one option (the “target”) but only partially inferior to the other (“competitor”).
In simple terms, marketers introduce a carefully crafted third choice that makes one of the original options look significantly more attractive by comparison.
This psychological principle is particularly powerful because it:
- Exploits our tendency to make relative rather than absolute value judgments
- Creates an easy justification for choosing the target option
- Makes decisions feel more rational even when they’re being subconsciously influenced
As behavioral economist Dan Ariely explains, “We don’t have an internal value meter that tells us how much things are worth. Rather, we focus on the relative advantage of one thing over another, and estimate value accordingly.”
How The Decoy Effect Works (The Psychology Behind It)
The Cognitive Science Behind the Effect
When the brain encounters multiple options, it doesn’t assess each one independently. Instead, it uses a comparative approach, looking for the best relative value. The Decoy Effect capitalises on this mental shortcut.
The psychological mechanisms at work include:
- Relative Advantage: The decoy makes the target option seem superior by comparison. This happens because humans struggle to evaluate absolute value but excel at comparing things.
- Loss Aversion: We’re more sensitive to potential losses than gains. A decoy manipulates our reference point, making the target option appear as a gain rather than a loss.
- Choice Justification: Decoys provide an easy rationale for our decisions. Research shows this effect is stronger when people know they’ll need to explain their choice to others.
- Anchoring Bias: The decoy creates a reference point that distorts our perception of value—much like how a £2,000 watch makes a £500 watch seem reasonable.
Scientific Validation
The effect was first identified in 1982 by researchers Joel Huber, John Payne, and Christopher Puto at Duke University, who demonstrated its influence on consumer preferences for beer and cars.
Their research showed that adding an asymmetrically dominated option (the decoy) significantly shifted preference toward the target option, contradicting the traditional economic principle that irrelevant alternatives shouldn’t affect choice.
More recent studies have confirmed the effect’s power while identifying important nuances:
- A 2023 study published in MDPI found that incongruent decoys can reduce framing effects, while congruent decoys amplify them in positive-framed scenarios.
- Research on diamond retailers found that when customers detected decoy options, sales of dominant alternatives increased by 1.8-3.2 times, resulting in a 14.3% gross profit increase.
However, some methodological debates exist. A comprehensive review found that of 91 attempts to reproduce the attraction effect across 23 product categories, only 11 produced reliable results—suggesting the effect is powerful but context-dependent.
Real-World Examples of The Decoy Effect
The Economist’s Subscription Strategy
The most famous demonstration comes from The Economist magazine’s subscription model:
- Web-only: £59
- Print-only: £125
- Print + Web: £125
The middle option—print-only at the same price as print + web—acts as the perfect decoy. Nobody would choose it, but its presence makes the print + web subscription appear as an exceptional value, driving more customers to the premium option.
Dan Ariely tested this setup and found that without the decoy, only 32% chose the most expensive option. With the decoy, that figure jumped to 84%—a remarkable 163% increase.
Starbucks Cup Sizes
Next time you’re at Starbucks, notice their pricing structure:
- Tall: Small price jump from Grande
- Grande: Positioned as the decoy
- Venti: Slightly higher price, much larger size
The pricing architecture makes the Venti appear as the best value-for-money option—exactly what Starbucks wants you to conclude.
Dating Apps and Choice Architecture
Beyond marketing, dating apps use the decoy effect to influence partner selection. People become more interested in a potential match when they see them alongside a similar but slightly less attractive decoy profile. This psychological manipulation shapes not just what we buy, but potentially who we date!
How The Decoy Effect Influences Consumer Behaviour
The Neurological Impact
When presented with a well-placed decoy, our brain’s decision-making centers light up differently. Neurologically, we process the target option more favorably because:
- The presence of the decoy simplifies our decision-making process by providing an easy comparison
- We experience a form of cognitive pleasure when finding what appears to be a “smart choice”
- The target option triggers reward anticipation in the brain’s ventral striatum
What Happens to Purchase Decisions
The Decoy Effect doesn’t just influence what we choose—it transforms how we feel about our choice. Consumers who select the target option report:
- Higher satisfaction with their decision
- Greater confidence in their choice
- Stronger perceived value for money
- Reduced decision anxiety and post-purchase regret
As one study participant noted, “I felt like I was getting a bargain, even though I spent more than I originally planned.”
Case Studies: How Marketers Use The Decoy Effect in Advertising
The Diamond Retailer’s Profit Boost
A particularly compelling study examined an online diamond retailer that implemented decoy-dominant pricing strategies. The retailer showed customers both dominant diamonds and slightly inferior “decoy” diamonds at similar price points.
Results:
- Most customers (75-89%) didn’t consciously notice the decoy effect
- When detected, sales conversions for dominant diamonds increased 1.8-3.2 times
- Overall gross profit increased by 14.3%
What makes this case study remarkable is the measurable financial impact and the fact that most customers never consciously recognised the psychological influence.
Legal Consultation Service Pricing Strategy
A law firm tested the decoy effect through its lead generation landing page:
Control Version:
- Basic Consultation: £99 (document review only)
- Comprehensive Consultation: £199 (review + legal advice)
Test Version:
- Basic Consultation: £99 (document review only)
- Comprehensive Consultation: £199 (review + legal advice)
- Premium Consultation: £249 (review + advice + written summary—slightly less desirable than Comprehensive)
The Premium option acted as a decoy, making the Comprehensive Consultation appear more valuable. The firm recorded a 43% increase in Comprehensive Consultation bookings with no change in overall traffic.
Practical Applications for Google Ads & Lead Generation
Google Ads Strategy
There’s not really room inside your Google Ads headlines and descriptions to show 3 prices unless you’ve got a very commodity service with prices being the main factor for clicks. This might work to build decoys for holiday package ads, for example, with hotel only, flights + hotel, and flights + hotel + experiences like tours etc included. Definitely worth testing if your market is at the point of buying and cost is a major factor. Let’s see how this could be tested…
- Service Comparison Ads: Create a three-tiered comparison in your Google Ads copy:
- Budget Package: £X
- Standard Package: £Y
- Premium Package: £Z (Carefully designed as a decoy to make Standard more appealing)
- Landing Page Integration: When users click through, ensure your landing page highlights the comparison, using visual cues to reinforce the value of your target option. Use comparison tables, pricing cards, or feature matrices to emphasise the relative value.
- A/B Testing Framework:
- Version A: Display only two service tiers
- Version B: Add a third “decoy” tier
- Track not only conversion rates but also which package visitors select
Lead Generation Website Optimization
- Service Package Structuring: For a web design agency:
- Basic Website: £499 (5 pages, basic design)
- Standard Website: £999 (10 pages, custom design, SEO optimized)
- Deluxe Website: £1,199 (10 pages, custom design, minimal SEO)
- Lead Magnet Form Options: Even your lead capture forms can leverage the Decoy Effect:
- Option 1: “Email me the guide” (email address only)
- Option 2: “Send me the guide + bonus templates” (email and phone)
- Option 3: “Share this page to download” (social sharing requirement—the decoy)
- Consultation Booking Forms: Financial advisors can structure their consultation offerings with a decoy:
- Free 15-minute call (no financial review)
- £99 Comprehensive Review (60 minutes, full analysis)
- £129 Premium Review (60 minutes, full analysis, basic written summary)
Why Marketers Should Care About The Decoy Effect
The Power of Choice Architecture
The Decoy Effect represents one of the most accessible tools in a marketer’s psychological toolkit. Unlike other techniques requiring complex implementation, decoy pricing can be deployed immediately with minimal investment.
For marketers, it offers:
- A way to guide consumer choice without restricting options
- Increased average purchase value without aggressive upselling
- Higher conversion rates on target products and services
- Enhanced perception of value without lowering prices
Ethical Considerations
While powerful, the decoy effect comes with ethical responsibilities:
- Transparency: Customers should never feel manipulated or deceived once they’ve made a purchase. All options, including the decoy, should genuinely be available.
- Value Alignment: The target option you’re steering customers toward should genuinely meet their needs—not just maximize your profits.
- Avoiding Exploitation: Be particularly careful when using this technique with vulnerable populations or for essential services.
- Trust Building: When used ethically, the decoy effect can actually build trust by helping customers identify real value in your offerings.
As marketing psychologist Nick Kolenda notes, “The difference between manipulation and persuasion is whether the audience benefits from taking action.”
How to Implement The Decoy Effect in Your Marketing Strategy
Step-by-Step Implementation Guide
- Identify Your Target Offering
- Determine which product/service you want to promote most
- Ensure it has genuine value and benefits for your customers
- Understand its key differentiating features
- Design an Effective Decoy
- Price it close to (or higher than) your target offering
- Make it clearly inferior in at least one important dimension
- Ensure it’s still a viable option someone might choose
- Test the Presentation
- Try different presentation formats (side-by-side comparison, pricing tables, etc.)
- Highlight the comparison factors that make your target option shine
- Consider using visual cues to draw attention to the value differences
- Measure the Impact
- Track conversion rates before and after implementing the decoy
- Monitor which options customers select
- Collect feedback to ensure customer satisfaction remains high
Common Pitfalls to Avoid
- Making the Decoy Too Unattractive If your decoy is obviously terrible, customers will see through the strategy and may lose trust. The decoy should be a legitimate option that simply doesn’t provide as much value as the target.
- Overcomplicating the Choice Architecture Too many options or comparison points can trigger choice paralysis. Keep your structure simple—typically three options work best.
- Neglecting Your Customer’s Actual Needs Never use the decoy effect to push customers toward options that don’t genuinely meet their needs. This leads to buyer’s remorse and damages long-term relationships.
- Failing to A/B Test The specific implementation of your decoy can dramatically impact results. Test different approaches to find what works best for your specific audience and offering.
A/B Testing Ideas
- Service Tiers Test Compare conversion rates between a two-tier and three-tier pricing structure, tracking which option customers select in each scenario.
- Decoy Positioning Test Test different ways of presenting your decoy option—as a “premium” offer versus positioning it as a “middle-ground” option.
- Feature Emphasis Test Experiment with highlighting different features in your comparison to see which creates the strongest decoy effect.
- Price Point Sensitivity Test how close the decoy price needs to be to the target price to maximize the effect. Is 5% more effective, or 15%?
Related Psychological Biases & Effects
The Decoy Effect doesn’t operate in isolation. It’s often more powerful when combined with these related psychological biases:
- Anchoring Bias The first price we see becomes a reference point for judging subsequent prices. Decoys can act as anchors, making target options seem more reasonable by comparison.
- Framing Effect How options are presented dramatically influences choice. The decoy effect is essentially a specialized form of framing that creates a specific comparison context.
- Status Quo Bias People tend to prefer the current state. Interestingly, research shows status quo bias often dominates over the decoy effect when they compete.
- Loss Aversion We feel losses more powerfully than equivalent gains. Decoys can reframe a higher price as a “gain” in value rather than a financial loss.
- Compromise Effect People tend to avoid extremes, preferring middle options. A well-placed decoy can make your target option appear as the sensible middle ground.
Understanding these related biases can help you design more sophisticated and effective choice architectures for your marketing strategy.
Why Marketers Should Care About The Decoy Effect
The Decoy Effect represents a powerful tool for marketers seeking to influence consumer choice without manipulative tactics. When implemented ethically, it helps customers recognize genuine value while allowing businesses to guide purchasing decisions toward mutually beneficial outcomes.
For lead generation specifically, it offers:
- Higher conversion rates on target service packages
- Increased average customer value
- Clearer decision pathways for prospects
- More confidence in purchasing decisions
- Lower acquisition costs as more visitors convert
As competition for attention intensifies, understanding psychological principles like the Decoy Effect isn’t just advantageous—it’s becoming essential for marketing success.

FAQs About Decoy Effect
What is the Decoy Effect and how does it influence our choices?
The Decoy Effect occurs when adding a third, inferior option (the decoy) influences preferences between two original options. This psychological bias leads consumers to change their preference between two options when presented with a third “asymmetrically dominated” alternative that’s completely inferior to one option but only partially inferior to another.
The effect works through several mechanisms:
- Relative advantage: Makes the target option appear superior by comparison
- Loss aversion: Shifts our perception of value by creating a new reference point
- Anchoring: The decoy’s price creates a mental reference point that makes the target option seem reasonable
For example, if you’re choosing between a small coffee (£2) and large coffee (£3.50), adding a medium-sized option at £3.25 can make the large seem like better value.
Who are the key researchers that first discovered the Decoy Effect?
Joel Huber, John Payne, and Christopher Puto first identified and described the Decoy Effect (also called the asymmetric dominance effect) in 1982 in their seminal paper. Their research at Duke University established the foundation for understanding how adding seemingly irrelevant options can significantly shift consumer preferences.
Later, Dan Ariely’s 2008 book “Predictably Irrational” popularized the concept through demonstrating how strategically inferior options influence people to choose more expensive items. Stanford marketing professor Itamar Simonson also made significant contributions to developing the understanding of this cognitive bias.
Can you provide some real-world examples of the Decoy Effect in action?
The Economist Subscription Strategy: One of the most famous examples involved three subscription options:
- Online-only: $59
- Print-only: $125 (the decoy)
- Print + Online: $125
The print-only option served as a decoy that made the print+online bundle appear to be exceptional value, significantly boosting sales of the combined subscription.
Starbucks Coffee Sizes: Starbucks pricing structure uses this effect with their tall, grande, and venti sizes. The price difference between tall and grande is relatively small, while the jump to venti is larger—but the grande serves as a decoy that makes venti seem like better value.
Diamond Retailer Case Study: An online diamond retailer implemented decoy pricing that increased their gross profit by 14.3%. When customers detected the decoy-dominant option, sales of the target diamonds increased by 1.8-3.2 times.
How is the Decoy Effect different from other psychological biases like the anchoring bias?
While related, the Decoy Effect differs from other biases in significant ways:
| Bias | How It Works | Relationship to Decoy Effect |
|---|---|---|
| Anchoring Bias | Initial information serves as a reference point for subsequent judgments | The decoy effect often leverages anchoring by creating price reference points, but specifically requires an asymmetrically dominated option |
| Framing Effect | How options are presented alters choices | Decoy effect uses a specific form of framing that involves adding a third option rather than just changing presentation |
| Status Quo Bias | Preference for current state/options | Research shows status quo bias often dominates over decoy effects in choice scenarios |
Unlike most other biases, the Decoy Effect specifically requires the introduction of a third option that’s clearly inferior to the target option but only somewhat inferior to the competitor option.
In what ways do marketers and advertisers take advantage of the Decoy Effect?
Marketers leverage the Decoy Effect through strategic pricing and product positioning:
- Tiered Pricing Strategies: Creating three-tier pricing where the middle or top option is positioned as the target by making another option serve as a decoy
- Subscription Models: Offering subscription packages where one option is clearly a better value than others (like The Economist example)
- Product Line Positioning: Placing premium products alongside “decoy” products with slightly lower prices but significantly lower features
- Service Packages: In service industries, creating service bundles where one package is intentionally designed to make another look more attractive
For lead generation, marketers might present consultation packages with a “premium” option that makes the “standard” option appear more reasonable while still encouraging upsells from the basic tier.
Are there any ethical concerns about exploiting the Decoy Effect to manipulate choices?
Several ethical concerns surround the use of the Decoy Effect:
- Manipulation: The effect exploits cognitive biases to influence decisions in ways consumers may not be aware of
- Transparency Issues: Many consumers don’t realize their choices are being deliberately shaped by decoy options
- Trust Erosion: If customers recognize the manipulation, it can damage brand trust and reputation
Best practices for ethical implementation include:
- Ensuring decoy options are still viable, valuable choices
- Being transparent about the value of each option
- Using the effect to help customers find genuinely better solutions rather than just boosting profits
When customers feel manipulated rather than guided, backlash can harm business relationships and brand perception long-term.
How can understanding the Decoy Effect help people make better decisions in their daily lives?
Understanding the Decoy Effect can empower you to make more rational decisions by:
- Recognizing Manipulation: Spotting when you’re being influenced by strategically placed decoy options in pricing or product offerings
- Evaluating Options Independently: Assessing each option based on its actual value to you, not just in comparison to other available options
- Focusing on Needs: Determining your actual requirements before reviewing options, making you less susceptible to comparative influence
- Removing Irrelevant Alternatives: Mentally eliminating options that don’t meet your core criteria before making comparisons
- Creating Decision Frameworks: Developing personal evaluation criteria before shopping that aren’t solely based on relative comparisons
This awareness helps particularly when making financial decisions, purchasing subscriptions, or choosing between service options where decoy pricing is common.
What are the neurological or cognitive mechanisms behind the Decoy Effect?
The Decoy Effect operates through several cognitive mechanisms:
- Relative Value Processing: Our brains struggle to determine absolute value and instead rely on comparisons between available options
- Loss Aversion: We’re more sensitive to potential losses than gains, so decoys exploit our tendency to avoid options that appear to offer less value
- Justification Need: The decoy provides an easy cognitive justification for selecting the target option, reducing decision anxiety
- Contrast Effects: The presence of an inferior option enhances the perceived value of the target option through contrast
- Cognitive Fluency: The decoy makes the comparison between options simpler by creating an obvious “winner” in the comparison
Research suggests the effect is stronger when people expect to justify their choices to others, indicating a social component to the cognitive bias as well.
Can you share any famous examples of the Decoy Effect from movies, TV shows, or literature?
While the Decoy Effect isn’t frequently named explicitly in entertainment, its principles appear in various narratives:
In films focusing on negotiation, sales, or marketing strategy, characters often employ decoy tactics—presenting an intentionally unattractive initial offer to make subsequent options seem reasonable. The concept also appears in stories about consumer manipulation and advertising psychology.
However, there aren’t well-documented instances of characters explicitly referencing the Decoy Effect by name in mainstream films or television. Instead, the concept typically appears as a strategic approach to influence decisions rather than being directly referenced.
For a verified real-world example, Dan Ariely’s demonstrations of The Economist subscription model in his books and TED talks are frequently referenced in marketing literature and business education.
How does the Decoy Effect compare to other decision-making biases like the halo effect?
The Decoy Effect differs from the halo effect and other biases in important ways:
| Decoy Effect | Halo Effect |
|---|---|
| Involves adding a third option to influence choice between two others | General impression of one characteristic influences perception of other unrelated attributes |
| Works through comparisons between options | Works through transfer of positive/negative feelings |
| Specifically related to choice architecture | Applies to person perception and brand evaluation |
| Requires introducing a strategically inferior alternative | Requires an initial positive/negative impression that spreads |
While the decoy effect is about manipulating choices through option comparison, the halo effect relates to how positive impressions in one area color our perception of unrelated attributes. Both affect decision-making but through different cognitive mechanisms.
What pricing or product strategies do companies use to leverage the Decoy Effect?
Companies use several strategic approaches to implement the Decoy Effect:
- Three-Tier Pricing: Creating basic, standard, and premium options with the premium or standard positioned as the target
- Same-Price Options: Offering two similarly priced options with one clearly providing more value (like The Economist’s print-only vs. print+online at the same price)
- Size Optimization: Presenting small, medium, and large options with pricing that makes the large option seem most valuable (used by Starbucks and movie theaters)
- Feature Bundling: Creating packages where a slightly more expensive option offers significantly more features than a decoy alternative
- Subscription Models: Structuring recurring payment options to guide users toward a specific target membership level
In service businesses, this might involve creating consultation packages where a mid-tier option appears most valuable when compared to basic and premium alternatives.
Are there any risks associated with the Decoy Effect creating unrealistic expectations?
Yes, several risks exist when using the Decoy Effect:
- Trust Erosion: If customers feel manipulated, they may lose trust in the brand
- Value Perception Issues: When customers realize they were influenced by comparison rather than absolute value, they may experience buyer’s remorse
- Backfire Effect: For sophisticated consumers who recognize the manipulation, the attempt may create negative brand associations
- Unrealistic Expectations: If the target option is positioned favorably only in comparison to a deliberately poor decoy, customers may be disappointed with its actual value
- Reduced Long-term Loyalty: While effective for immediate conversions, manipulation through decoys may harm customer retention if value doesn’t meet expectations
To mitigate these risks, companies should ensure all options—including decoys—provide genuine value and aren’t merely manipulation tools.
In what professional or social situations might the Decoy Effect play a role?
The Decoy Effect extends beyond retail into various professional and social contexts:
- Job Offers: Companies might present compensation packages where one component makes another appear more attractive
- Dating Choices: Research shows people may find a potential partner more attractive when seen alongside a similar but slightly less attractive alternative
- Health Decisions: Healthcare providers might structure treatment options to nudge patients toward a preferred approach
- Professional Services: Consultants, lawyers, and financial advisors often present service tiers designed to direct clients toward specific packages
- Negotiation Strategy: Adding a less favorable term that can be conceded makes remaining terms seem more reasonable
In service-based industries, consultation offerings and proposal structures frequently employ this psychology to guide prospects toward mid-tier service packages.
Have any studies challenged the validity or prevalence of the Decoy Effect?
Yes, some research has questioned how consistently the Decoy Effect operates:
- A meta-analysis found that in 91 attempts to produce the attraction effect across 23 product classes, only 11 reliable effects emerged—significantly fewer than expected given the studies’ statistical power
- Research by Gerasimou (2022) found no evidence for the decoy effect in choice under risk, with status quo bias dominating instead
- Studies suggest the effect varies significantly based on:
- Product category
- Cultural context
- Individual differences
- Decision complexity
- Consumer sophistication
These challenges don’t invalidate the effect but suggest it works within specific contexts rather than universally. Methodological differences in testing approaches may also contribute to inconsistent findings.
How can content about the Decoy Effect be optimized for better search engine rankings?
To optimize content about the Decoy Effect for search engines:
- Use Relevant Keywords: Include terms like “asymmetric dominance effect,” “attraction effect,” “comparative choice,” and “decoy pricing strategy”
- Create Practical Examples: Develop detailed case studies showing the effect in action across different industries
- Link to Authoritative Sources: Reference academic research from reputable journals and institutions like Duke University (where the effect was first documented)
- Develop Visual Assets: Create comparison charts, infographics, and decision trees that illustrate how the effect works
- Address Related Topics: Cover connected concepts like anchoring bias, framing effects, and consumer psychology principles
- Target Specific Industries: Create specialized content about how the effect applies in e-commerce, SaaS pricing, retail, and service businesses
For Google Ads specialists, content connecting the effect to conversion rate optimization and landing page design will perform particularly well.
