The Decoy You Don't See

Sometime around 2008, Dan Ariely noticed something odd about The Economist's subscription page. They were offering three options.

Online-only access for $59. Print-only for $125. Print and online together for $125.

Read that again. The print-only subscription and the print-plus-online subscription cost exactly the same. Why would The Economist offer a print-only option at $125 when you could get print and online for the same price? It looked like a mistake. It wasn't.

Ariely ran the experiment with 100 MIT students. With all three options on the table, 84% chose the print-plus-online combo and 16% chose online-only. Nobody chose print-only. The middle option got zero takers. It looked completely useless.

So Ariely removed it. Same two remaining options, new group of 100 students. This time 68% chose the cheap online-only plan and only 32% chose the expensive combo.

Same products. Same prices. The only thing that changed was the removal of an option nobody was choosing anyway. And revenue dropped from $11,444 to $8,012. A 43% swing, caused entirely by a ghost. An option that existed not to be chosen, but to make another option look irresistible.

This is the decoy effect. And it's one of those ideas that, once you understand it, makes you realize you've been making decisions inside other people's architecture your entire life.

The decoy effect was first described by Joel Huber, John Payne, and Christopher Puto in 1981. The formal name is "asymmetric dominance." The idea is simple but the implications are not. When you add a third option that is clearly worse than one of the original two but only ambiguously worse than the other, people shift their preference toward the option that dominates the decoy. The decoy doesn't need to attract a single customer. It just needs to exist. Its presence changes the comparison, and the comparison changes the choice.

I think this is one of the most underappreciated ideas in business, because most people hear about the decoy effect and think it's a pricing trick. Some clever hack you put on your SaaS page. And it is that. But the deeper version is more interesting. The decoy effect reveals something fundamental about how people make decisions. We don't evaluate things in absolute terms. We evaluate them relative to whatever else is in front of us. And whoever controls the set of options controls the decision.

Let me give you the Netflix version of this.

Netflix currently offers three plans in the US. Standard with ads for $7.99 a month. Standard without ads for $17.99. Premium for $24.99. The gap between the cheapest plan and the most expensive is 213%. That's a huge spread. And it's deliberate.

Now, Netflix isn't running an Economist-style decoy in the classic sense. All three plans get purchased. But the structure does something similar. The ad-supported plan exists partly to make the standard plan feel worth the upgrade. You're not just paying $17.99 for Netflix. You're paying $10 more to never see an ad again. The premium plan, meanwhile, anchors the high end. It makes $17.99 feel like a reasonable middle ground, even though $17.99 a month for a streaming service would have seemed insane five years ago.

The middle option looks like the sensible choice. But "sensible" is a feeling created by context, not by the product itself. Remove the top tier and the middle tier suddenly looks expensive. Remove the bottom tier and the middle tier loses its "no ads" advantage. The plan only feels right because of its neighbors.

This is the standard three-tier SaaS pricing page that every software company uses, and I think most founders don't realize why it works. The typical setup is a basic plan, a "popular" or "recommended" plan (usually highlighted with a different color or a badge), and an enterprise plan. The enterprise plan is usually priced aggressively high. Often unrealistically high for most customers. And that's the point. The enterprise tier isn't there to sell. It's there to make the middle tier look reasonable.

If you only showed customers two options, basic and pro, they'd compare the two and many would pick basic. But add a third option that's dramatically more expensive than pro, and suddenly pro looks like the smart choice. The expensive option reframes the comparison. The customer thinks they're making a rational decision. They're choosing the best value. But the set of options was designed so that "best value" would mean exactly what the company wanted it to mean.

I think the reason this works so reliably is connected to something deeper about human cognition. We are not good at knowing what things are worth. This sounds obvious when you say it out loud, but the implications are profound. When someone asks you whether $17.99 a month is a fair price for a streaming service, you can't answer that question from first principles. There's no internal calculator that spits out a number. What you actually do is look at what else is available, compare the options, and pick the one that feels right relative to the others.

Dan Ariely put it well: "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."

This means that the frame is the product. Not the thing you're selling. The set of options you present around the thing you're selling. Two identical products can produce wildly different purchase decisions depending on what other options are sitting next to them on the page.

If you want to sell a $59 subscription, you could just put it on a page by itself. But you'll sell more of them if you put a $125 option next to it that's clearly worse, because the $59 now looks like a bargain. And you'll sell even more of the $125 combo if you put a $125 print-only option next to it, because the combo now looks like a steal. Nothing about the products changed. Only the frame changed. And the frame was enough to move 43% of the revenue.

I think most founders think about pricing as a math problem. What does this cost us to deliver? What's the market willing to pay? What are competitors charging? These are the right questions, but they're incomplete. The missing question is: what other options am I showing alongside this one, and how do those options shape the perception of value?

The thing that seems useless often turns out to be the most load-bearing part of the system. The Economist's print-only option generated zero direct revenue. Nobody bought it. But removing it cost the company 43% of its subscription income. The option that seemed like a mistake was quietly doing more work than either of the real options.

This extends beyond pricing. I think the same dynamic shows up in how companies position features, how founders pitch investors, and how people make career decisions. In every case, the options you don't choose still shape the options you do. The rejected path isn't inert. It's part of the architecture of your decision. And the people who understand this build choice environments that guide decisions without anyone feeling guided.

That's the unsettling part. The decoy effect works precisely because the person making the choice doesn't notice it. They feel like they're comparing options rationally. They feel like they're finding the best deal. The whole mechanism depends on the customer believing their decision was theirs.

Every pricing page you've ever seen with three tiers was designed by someone who understood this. The recommended plan is recommended because of its neighbors. The enterprise plan is priced to make the middle plan look smart. And the basic plan exists to make the middle plan look worth the upgrade.

The options are the product. The thing you think you're choosing between is just the set someone else built for you.
