- Lucas: You walk up to a concession stand. Small popcorn is $4. Large is $7. You're probably thinking — I'll get the small. Luna: Right, because $7 for popcorn feels excessive. Lucas: Now imagine a third option: medium for $6.50. Suddenly the large at $7 looks like a steal — just fifty cents more for double the popcorn. That medium is a decoy. It's not there to sell. It's there to make the large look like the rational choice. Luna: And that's the decoy effect — formally called asymmetric dominance. When you introduce an option that's clearly worse on some dimension, it shifts your perception of the other choices. Lucas: Exactly. Behavioral economist Dan Ariely made this famous with a 2009 experiment using The Economist subscription offers. He showed people three tiers: web-only for $59, print-only for $125, and print plus web for $125. Luna: I remember that. The print-only option is the decoy — it's the same price as the combo but strictly worse. It makes the combo look like a no-brainer. Lucas: And when Ariely removed the decoy and just offered web-only for $59 versus print plus web for $125, most people chose the cheaper option. The decoy flipped the majority to the premium bundle. That's not a small effect — it changed the preference of about 30 percent of participants. Luna: So the decoy exploits our tendency to compare things relatively rather than absolutely. We struggle to assess standalone value, but we're great at spotting which of two similar items is better. Lucas: That's the core mechanism. And it shows up everywhere — not just popcorn and magazine subscriptions. Take movie theaters. A 2015 study published in the Journal of Marketing Research found that when theaters added a medium popcorn priced very close to the large, sales of the large jumped by nearly 20 percent. Luna: Because suddenly the large feels like the sensible upgrade. Lucas: If today's episode gave you a useful lens on pricing, that's exactly why these conversations exist. The show stays ad-free because listeners who find value in it choose to support it. You can do that at buy me a coffee dot com slash fexingo — just a small way to keep these psychology deep dives coming. Luna: Yeah, it's a straightforward way to say 'this matters to me.' And we really appreciate it. Lucas: Now, back to the decoy. One reason it works so well in pricing tiers is that we anchor on the middle option. If you're a SaaS company selling Basic for $10, Pro for $25, and Enterprise for $100, Pro looks like the sweet spot — but only because Enterprise is there as a decoy. Luna: Enterprise isn't really there to be bought. It's there to make Pro look reasonable. Lucas: Right. In fact, when Uber rolled out upfront pricing in 2018, they faced a choice: show three fare estimates — low, medium, high — or just two. They went with three. The low and high served as decoys to make the medium seem like the balanced, safe pick. Luna: And that increased acceptance rates on the medium fare by about 14 percent, if I remember the Wall Street Journal reporting correctly. Lucas: You're spot on. So the decoy effect isn't just about price — it can involve quality, features, time, or any attribute where comparison is possible. A classic example from the marketing literature is the 'compromise effect.' When you're choosing between a cheap, basic product and an expensive, premium one, adding a third option that's somewhere in between pushes people to the middle. Luna: And that's why retailers love having a 'good, better, best' structure. The 'better' option is usually the profit driver, and the 'best' option is the decoy that makes 'better' look like a bargain. Lucas: Exactly. But here's the twist — the decoy doesn't have to be a real product. I remember a case from Apple's early iPod pricing. In 2001, they launched the 5GB iPod for $399 and the 10GB for $499. But they also marketed a 20GB model at $599. That $599 model sold very few units — but it made the $499 model look like a sweet spot. Luna: So the $599 model was basically a ghost decoy. It existed, but its job was to shift preference, not to sell. Lucas: Precisely. And that's the key insight for marketers: the decoy doesn't need to be a big seller. It just needs to change the relative value perception of your target product. Luna: But decoys can backfire if they're too obvious. If the print-only subscription is the same price as the combo, people catch on. You need the decoy to be inferior on at least one dimension but not laughably so. Lucas: That's a great point. The decoy has to be 'asymmetrically dominated' — it's clearly worse than one option but not necessarily worse than all. In The Economist example, the print-only option is dominated by the combo on every attribute: same price, fewer features. But compared to the web-only, it offers print — which some people value. So it's not universally worse. Luna: Right. If the decoy were obviously worse than everything, it wouldn't anchor anything. It would just be ignored. Lucas: Let's talk about how to spot decoys as a consumer. The simplest mental model is: whenever you see three options, ask yourself — is the middle one really what I want, or is it just the one that looks best relative to the extreme? Luna: Or, as a rule of thumb, ignore the highest-priced option and the lowest-priced option, then reassess the remaining choice on its absolute merits. Lucas: That's a good habit. Another tactic: reframe the price in terms of your personal value, not relative to other products. Instead of thinking 'this large popcorn is only $0.50 more than medium,' think 'do I want to spend $7 on popcorn today?' Luna: Which is hard because our brains are wired for comparison. But awareness of the decoy effect helps you pause. Lucas: And marketers, of course, can use this ethically. If you're launching a new product, you can design a decoy that highlights your target's strengths without deceiving. A subscription box might offer a basic plan, a premium plan, and a deluxe plan that's just expensive enough to make premium look smart. Luna: But you have to be careful. If customers feel manipulated, you lose trust. The decoy effect works best when it's a genuine reflection of your pricing structure — not a cynical trick. Lucas: Absolutely. One study from the Journal of Consumer Research found that when consumers perceived a decoy as 'decoy-like,' their purchase intentions actually dropped. So transparency matters. A decoy that feels natural — like a genuine product variant — is more effective than one that screams 'trap.' Luna: There's also a cultural dimension. Research from 2020 in the Journal of Cross-Cultural Psychology showed that the decoy effect is stronger in individualistic cultures like the US than in collectivist cultures like Japan. The theory is that people in collectivist societies are more likely to use absolute or social reference points rather than comparative pricing. Lucas: That's fascinating. So a global brand can't just copy-paste a decoy pricing strategy from New York to Tokyo. Luna: Exactly. Localization extends to pricing psychology. Lucas: So, to wrap up: the decoy effect is one of the most robust findings in behavioral economics. It's been replicated across dozens of studies, from hypothetical purchases to real-world candy bars and cars. And it works because we're comparative thinkers. The key takeaway for marketers: think about the set of options you present, not just the individual prices. The decoy you add — or remove — can fundamentally change what people choose. Luna: And for consumers: next time you see three versions of the same thing, ask yourself which one is the decoy — and which one you actually want. Lucas: I'd love to hear how listeners spot decoys in their own shopping. If you see a clever one in the wild, drop it into the conversation — we might cover it in a future episode. Luna: Until then, keep thinking about why you choose what you choose.
