The Decoy Effect in Your Offer

Welcome to the second module of the Pricing Track. This module is about one of the most fascinating perception principles I know in pricing: the decoy effect. A third option that nobody is supposed to buy suddenly changes how customers perceive the other two. Build the decoy right, and you steer the choice toward your preferred option without forcing anyone and without changing the price. I'll show you how it works and where the ethical line is.

After this module, you'll have three new skills. First, you'll understand why an obviously inferior option changes how people choose. Second, you'll build decoys yourself that make your target option look more attractive. Third, you'll assess where the ethical line is between helpful guidance and manipulation.

Two quick questions before we start. Do you currently offer two or three options? And would you introduce a third option knowing it will rarely be chosen? If you hesitate at the second question, that's completely understandable. By the end of this module, you'll know why that kind of option can actually make solid business sense, as long as it's constructed fairly.

What does the decoy effect actually mean for your revenue? When customers choose between two options, they often go with the cheaper one. Add a third option that's clearly inferior, and the picture shifts. Suddenly one of the original options feels much more attractive. In practice, this can move the share of your preferred option dramatically.

The decoy effect is one of the most thoroughly researched phenomena in behavioral economics. It shows that people don't evaluate options in isolation; they always compare. A third option that's clearly worse than the target option, but only on one dimension, suddenly makes the target the obvious winner.

The technical term is asymmetric dominance. It means the decoy might actually outperform the target option on one attribute, but it falls clearly short on another. That creates a simple comparison: the target option is the obvious sweet spot between performance and price. The decoy almost never gets bought, but it makes the target option look compelling.

The popcorn example is the classic case. When the only options are Small for €3 and Large for €7, many people go with the cheaper Small. The moment you add a Medium for €6.50, paying just fifty cents more for Large suddenly feels like a no-brainer. Medium almost never sells, but it sells Large. That's the decoy effect in its purest form.

People want to feel good about their decisions. A decoy gives them a simple justification: I'm choosing the option that clearly offers more value for the money. The brain no longer has to weigh complex trade-offs; it sees a clear winner. That simplified decision takes the pressure off the customer while increasing revenue at the same time.

Let's look at a software example I've seen with several SaaS clients. Basic costs €99, Pro costs €199. A lot of customers choose Basic because Pro seems twice as expensive by comparison. Add a Premium tier at €209 and the picture changes completely. Premium is slightly more expensive than Pro but offers only a handful of extra features. Suddenly Pro looks like the sensible middle ground: far more functionality than Basic, and a much better price-to-value ratio than Premium. Pro's share of revenue goes up. The prices of the original two tiers stayed exactly the same.

A good decoy follows four rules. It must be comparable to the other options so the comparison works. It must be asymmetrically worse, meaning better on one dimension but worse on the more important one. It must draw attention to the target option. And it must stay fair, because an unfair decoy feels manipulative and damages trust.

Here's a real-world agency scenario. Starter costs €1,000, Growth costs €2,500. Many clients choose Starter because Growth seems expensive by comparison. Then the shop introduces Enterprise at €3,000. Enterprise offers only slightly more than Growth but costs €500 more. Suddenly Growth looks like the smart choice. Growth's share increases by 18%, and the price of Growth hasn't changed at all. With 20 new clients per month, that translates to an additional €9,000 in monthly revenue.

This is where the ethical line sits. A decoy is legitimate when it genuinely helps customers make sense of their options. If all three options offer real value, the third option is a fair decision aid. But if the decoy is deliberately bad or unusable just to mislead customers, it erodes trust and ultimately damages the brand.

Quick check-in. Remember: the decoy works because people make decisions in relative terms. A good decoy is comparable to the other options but worse than the target option on the dimension that matters most. That steers the choice, and you don't have to lower a single price to make it happen. Once that's clear, let's look at what this looks like in practice.

A SaaS provider had two tiers. The cheaper one was chosen 60% of the time. After introducing a Premium decoy, 55% of customers chose the middle tier. Average revenue per customer rose by 25%. With 500 new customers per year and an average revenue of €8,000, that's an additional €1,000,000 in annual revenue. The key point: the prices of the original two tiers stayed the same. The offer structure alone changed what people chose.

The decoy effect is powerful, and that's exactly what makes it tricky. If the third option is obviously there just to mislead the customer, it feels manipulative fast. An ethical decoy offers real, if specific, value. It helps the customer find the option that's right for them. Keep that line in mind, and you'll strengthen not just revenue but also trust.

Picture a simple matrix: one axis is price, the other is performance. Your target option should sit at the optimal ratio, meaning a lot of performance for the price. The decoy sits close to the target on one axis but clearly worse on the other. For example, the decoy offers only marginally more performance but costs significantly more. That creates a visually clear signal: the target option is the sensible choice.

A classic mistake: a shop introduces a decoy, and it suddenly accounts for ten or fifteen percent of purchases. That sounds fine, but it's a warning sign. The third option is no longer a navigational aid. It's become a product in its own right that you now have to maintain. Worse, it can actually crowd out your target option. That's why you need to watch the numbers closely after launching a decoy. If it's being chosen too often, your structure is off.

Do this now for your own offer. Take your two most important options and design a third. That third option should either be significantly more expensive for only a little more performance, or noticeably weaker for almost the same price. One thing matters: every option has to offer real value. If the decoy feels fair, you've created a new sales opportunity. I'd recommend testing the decoy internally with three colleagues first. If the manipulation is immediately obvious, it's too on the nose.

Three classic mistakes. First: the decoy is so obviously unattractive that customers feel they're being played. Second: the offer structure is unclear, so the decoy doesn't steer the choice toward the intended option. Third: the decoy suddenly gets purchased frequently. At that point it's no longer a decoy. It's a new main product you have to maintain.

In how you display the options, order matters too. The target option should be visually highlighted, for example with a label like "Most Popular" or "Recommended." The decoy typically sits right next to the target option so the direct comparison works. The clearer the feature comparison, the stronger the decoy effect.

Three sentences to sum it up: the decoy effect guides the choice by introducing a third option that's asymmetrically worse. A good decoy highlights the target option without misleading the customer. And the effect only stays ethical when all options offer real value and the customer can make a transparent decision. In my experience, the best decoys are the ones that genuinely help customers get their bearings.

You now know how decoys shape perception. The next module covers how to group multiple products into an attractive bundle. Bundling is another way to increase cart value without having to change the price of any individual product.
