- Lucas: Luna, I want to start with a trip to the movie theater. You walk up to the counter, and there are three popcorn sizes: small for four dollars, medium for six fifty, and large for seven fifty. Luna: Right, and almost everyone picks the large, because seven fifty feels like a steal compared to six fifty for the medium. Lucas: Exactly. But here's the thing — that medium size isn't really meant to sell. It's a decoy. Its only job is to make the large look like the obvious value choice. Luna: So the theater isn't hoping you'll buy medium. They're using it to steer you to the large, which has way higher profit margins. Lucas: That's the decoy effect in a nutshell — also called asymmetric dominance. Add a third option that's slightly worse than one of the others, and suddenly that 'target' option becomes more attractive. It's one of the most reliable pricing tricks in marketing. Lucas: Before we go deeper — if these marketing conversations have sparked something you've actually used at work or just in your own shopping, and you want to help keep this show ad-free, you can support us at buy me a coffee dot com slash fexingo. No pressure, just a simple way to say this content matters to you. Luna: And we really appreciate it. Every bit helps us keep digging into these fascinating corners of consumer behavior. Lucas: So back to the decoy. The classic academic example comes from Dan Ariely's research with The Economist subscription offers. In one test, people saw three options: web-only for fifty-nine dollars, print-only for one hundred twenty-five, and print plus web for one hundred twenty-five. Luna: Wait — the print-only and the print plus web were the same price? That seems like a typo. Lucas: It's not a typo. The print-only option is the decoy. It's clearly worse than the print plus web combo because you're paying the same price but getting less. When that decoy is present, a huge majority picks the combo. But when you remove the decoy and just offer web-only versus print plus web, preference shifts heavily toward the cheaper web-only. Luna: So the decoy doesn't just influence choice — it completely flips the majority preference. That's powerful. Lucas: Right. And it works because humans are terrible at evaluating options in isolation. We need comparison. The decoy gives our brain a shortcut: 'Option A is better than Option B in every way, so I'll pick A.' We feel smart about it, but the marketer designed that feeling. Luna: Are there real-world examples beyond popcorn and magazines? I'm thinking about Apple's pricing. Lucas: Great call. Apple often uses a decoy in its iPhone lineup. When they release three models — say, the base model, the Pro, and the Pro Max — they price the Pro very close to the Pro Max. The Pro becomes the decoy. It's not much cheaper than the top model, but you get noticeably less storage or camera capability. So the Pro Max looks like the rational upgrade. Luna: And the base model is still there for budget-conscious buyers, but the whole structure pushes people toward the highest margin option. Lucas: Exactly. Another place you see it constantly is subscription tiers. Think about Spotify or Netflix. They'll have a basic plan, a standard plan, and a premium plan. Often the standard plan is priced just a dollar or two below premium, but with a clear limitation like lower resolution or fewer screens. That standard plan is the decoy — it's there to make premium feel like the obvious choice. Luna: So if you're a marketer designing a pricing page, you want to intentionally create a decoy that's slightly worse than your target option, but not so bad that it's ignored. Lucas: Precisely. The decoy has to be dominated by the target — meaning the target is better on every dimension that matters. But the decoy also has to be comparable enough that it seems like a legitimate option. If it's obviously terrible, it doesn't work because people dismiss it entirely. Luna: Is there a risk of backlash? If customers figure out they're being manipulated, do they resent the brand? Lucas: It can happen if it feels deceptive. But most people never consciously notice the decoy. They just feel good about their choice. The key is to make the decoy plausible. If you price a medium popcorn at eight dollars when small is four and large is seven fifty, that's too obvious. It has to be in the ballpark. Luna: So the art is in the details. One study I remember found that adding a decoy can increase sales of the target by up to thirty percent. Lucas: I've seen numbers in that range too. And it's not just about price. The decoy effect works with any attribute — quality, features, speed, even aesthetics. For example, a car dealership might show you a base model, a mid-tier, and a luxury trim. The mid-tier is loaded with options that push the price close to the luxury trim, making the luxury look like a better deal. Luna: That's fascinating because it means you can apply the decoy effect across many industries, not just consumer goods. Lucas: Absolutely. I've seen it in SaaS pricing, in healthcare plans, even in charitable donations. A nonprofit might offer three donation levels: twenty-five dollars, fifty dollars, and one hundred dollars. If they want to push the hundred-dollar option, they can add a seventy-five-dollar option that offers the same benefits as the hundred-dollar one but with a less appealing thank-you gift. Suddenly, the hundred-dollar tier seems like the best value. Luna: Does the decoy effect work equally well online and in person? I imagine in a physical store, people might have less time to compare. Lucas: It works in both, but the presentation matters. Online, you can control the layout — put the decoy next to the target, use visual cues like highlighting or badges. In person, it's about shelf placement and signage. The key is making the comparison easy. If the customer has to do mental math, the effect weakens. Luna: So a good decoy is one that requires almost no cognitive effort to see as inferior. Lucas: Right. The best decoys are intuitively worse. Like the print-only Economist subscription — you immediately see it's the same price for less. No calculation needed. Luna: What about ethical boundaries? At what point does the decoy become manipulative rather than persuasive? Lucas: That's a great question. I think it crosses a line when the decoy is completely fake — when you have no intention of selling it. Some retailers have been criticized for listing 'phantom' products that exist only to make another item look good. If customers find out, you lose trust. Luna: So the decoy has to be a real option that someone might actually buy, even if few do. Lucas: Exactly. If it's a real product with real value, even if it's not the best seller, it's ethical. The popcorn medium is a real size — some people might prefer it. But its presence changes the choice architecture. Luna: I want to circle back to something you said earlier about the decoy effect being asymmetric dominance. Can you explain that term? Lucas: Sure. Asymmetric dominance means the decoy is dominated by the target on all attributes, but only partially dominated by the competitor. In the popcorn example, the medium is dominated by the large on both price and quantity — large gives you more popcorn for just one dollar more. But the medium is not dominated by the small — small is cheaper but gives you less. So the dominance is asymmetric: the target dominates the decoy, but the competitor doesn't. Luna: That asymmetry is what makes the target stand out as the winner. Lucas: Exactly. And it's why the decoy effect is so robust. It's been replicated in dozens of studies across cultures and contexts. It's not a fluke — it's a fundamental quirk of how our brains compare options. Luna: Given that, should every pricing page have a decoy? Or are there situations where it backfires? Lucas: It can backfire if your product line is too simple. If you only have two options, adding a third just to be a decoy might confuse customers or clutter the decision. Also, if your target option is already the best value, adding a decoy might not move the needle much. The effect is strongest when the target and competitor are close in attractiveness — the decoy breaks the tie. Luna: So it's a tool for tipping the scale when choices are nearly equal. Lucas: Exactly. And it's especially useful when you want to steer customers toward a higher-margin option without discounting it. Instead of lowering the price, you make the competitor look worse by comparison. Luna: I think the takeaway for marketers is to look at their pricing tiers and ask: is there an option that's almost as expensive as our premium but offers less? If not, we might be missing a decoy opportunity. Lucas: That's a perfect summary. And for consumers, awareness is defense. Next time you're choosing between three options and one feels like an obvious no-brainer, pause and ask: is that no-brainer actually the best for me, or is it just the best compared to a decoy? Luna: That's a good habit. I'll definitely be more critical of my popcorn choices from now on. Lucas: Same here. And that's the decoy effect — a small nudge with big consequences.
