- Lucas: Let’s talk about the time I almost bought a magazine subscription that didn’t exist just to make another one look better. It was back in my early twenties, standing in a grocery store aisle, staring at three boxes of premium coffee subscriptions. One was a basic monthly box for thirty dollars. Another was a weekly delivery for sixty dollars. And then there was a third box, identical in design but priced at fifty-five dollars, offering only monthly delivery. Luna: Right, so the fifty-five dollar box was the decoy. It made the sixty dollar weekly box look like a steal by comparison, even though it was twice as expensive as the basic option. Lucas: Exactly. That fifty-five dollar option is what behavioral economists call the asymmetric dominance alternative, or more commonly, the decoy. Its sole purpose isn’t to sell itself. It’s to distort your perception of value so that the target option—the sixty dollar weekly subscription—seems rational. I walked out with the weekly plan, convinced I was getting a deal, when I had no intention of actually drinking coffee that fast. Luna: It’s fascinating because we think we’re comparing absolute values, but we’re actually doing relative comparisons. The decoy creates a reference point that shifts the entire scale. Lucas: That’s the core mechanism. When you have two options, A and B, your brain struggles to weigh them against each other directly. But add C, which is clearly worse than B but slightly different from A, and suddenly B looks superior on every measurable dimension. It’s not that B changed. It’s that C changed how you see B. Luna: So it’s less about the product itself and more about the structure of the choice presented to you. Like a menu designed to push you toward the most profitable item. Lucas: Precisely. And this happens everywhere now, especially in digital services. Take streaming platforms. They used to offer just two tiers: ad-supported and ad-free. Now they offer three. There’s the standard plan, the premium four-k plan, and then a mid-tier plan that has ads but offers higher resolution than the cheapest option. That mid-tier plan is rarely the best value. It exists to make the premium plan look reasonable. Luna: I’ve noticed that with software too. The professional tier always seems to have one extra feature that makes the enterprise tier look like it’s not worth the huge price jump. Lucas: Yes, and that’s where it gets tricky for investors. We often apply this logic to our own portfolios without realizing it. Consider mutual fund share classes. You might see a retail class, an institutional class, and then a separate account option that falls in between. The fees aren’t always linear. Sometimes the middle option has higher expense ratios than the lowest tier but lower than the highest, yet it’s positioned as the smart compromise. Luna: But if you actually do the math, the lowest fee option usually wins over a long horizon. So why does the middle one feel safer? Lucas: Because safety feels like a middle ground. We associate extremes with risk. The high-fee option feels greedy, the low-fee option feels cheap or possibly risky due to lack of service. The middle option feels balanced. But in finance, balance is often just a mask for mediocrity. Lower fees compound into significantly higher returns over decades. Luna: So the decoy doesn’t just trick us into buying more coffee. It tricks us into paying more for financial services that should be transparent. Lucas: And it’s not just prices. It’s features too. Look at credit cards. You have a basic card with no annual fee, a travel card with a high fee but massive points, and then a card in the middle with a moderate fee and decent points. The moderate card is almost never the optimal choice for anyone. It’s designed to capture people who want to avoid the extreme of the no-fee card but don’t want to commit to the full travel ecosystem. Luna: It’s a trap for the indecisive. If you knew exactly what you wanted, you’d pick either the basic or the premium. The decoy catches everyone else. Lucas: Right. And the people who catch themselves in these traps often feel guilty, thinking they made a bad personal choice. But really, they were playing a game where the rules were rigged before they sat down. The designer already decided what they wanted you to choose. Luna: That’s a powerful way to put it. It shifts the blame from individual decision-making to structural manipulation. Lucas: Before we dig deeper into how to protect yourself from this, I want to mention something important. This show is produced independently, and keeping it ad-free and consistent takes real effort. A couple of dollars a month is genuinely what keeps these going — buy me a coffee dot com slash fexingo. If you've gotten something out of the analysis, it helps us keep digging into these patterns. Luna: Yeah, and it lets us spend more time on the deep dives rather than chasing quick clicks. It makes a real difference. Lucas: Thanks for considering that. Now, let’s get back to the mechanics of the decoy. Because once you see it, you can’t unsee it. But knowing it’s there is only half the battle. You have to understand how to neutralize it. Luna: So how do you stop the bias from influencing your actual wallet? Do you just ignore all the middle options? Lucas: Not necessarily ignore them, but evaluate them differently. The first step is to identify the target. Ask yourself: which option is the company trying to push? Usually, it’s the one that appears immediately after the decoy. If there’s a mediocre option right next to a great option, the mediocre one is likely the decoy. Luna: So you reverse-engineer the menu. You look for the option that is dominated by another single option on every key metric. Lucas: Exactly. In economics terms, a dominated alternative is one that is strictly worse than another available option. If Option C costs more than Option B but gives you less of everything, C is dominated. If C is dominated by B, then C is likely a decoy meant to make B look good. You can safely discard C and compare A and B directly. Luna: That simplifies the decision matrix. Instead of juggling three variables, you just eliminate the noise and focus on the two viable paths. Lucas: It does. And it forces you to ask a harder question: which of the remaining two options actually aligns with my needs? Often, the answer is the cheaper one. We let the decoy convince us that we need the upgrade. But if we remove the decoy, we might realize the basic option is sufficient. Luna: I love that. It turns the marketing tactic against itself. You use their structure to expose their intent. Lucas: And it applies to non-financial decisions too. Think about job offers. You might get an offer with a certain salary, then a second offer with slightly less base pay but better benefits, and a third offer that’s terrible in every way except it’s at a famous company. The terrible offer is the decoy. It makes the second offer look attractive by contrast, even if the first offer was actually the best overall package. Luna: The prestige factor acts as a multiplier for the decoy. People overlook the financial reality because the brand name softens the blow. Lucas: Exactly. Prestige is a powerful decoy because it adds a qualitative dimension that’s hard to quantify. But if you strip away the brand and look at the compensation, benefits, and growth potential, the math often favors the lesser-known employer. Luna: So the lesson is to quantify everything. Turn qualitative feelings into quantitative data before you decide. Lucas: Yes. Create your own spreadsheet. List the attributes that matter to you: cost, time, quality, risk. Assign weights to each. Then score each option. If you do this rigorously, the decoy loses its power because you’re no longer relying on intuition. You’re relying on calculation. Luna: It’s work, but it’s the kind of work that pays off. Most people skip the spreadsheet because it’s boring, and that’s exactly when they get manipulated. Lucas: Boring is the friend of the smart investor. Excitement is usually the friend of the marketer. The decoy effect thrives on excitement. It creates a sense of urgency and specialness around the target option. Luna: So staying bored is actually a competitive advantage. It keeps you grounded when everyone else is chasing the shiny middle option. Lucas: I think so. And it’s worth noting that companies know this. They test different configurations of decoys to see which one converts best. They are constantly optimizing the menu to exploit this bias. So our defense must be constant vigilance. Luna: Vigilance and simplicity. Strip away the extras, look at the fundamentals, and stick to what you actually need. Lucas: Right. The next time you face a choice with three options, pause. Look for the one that is clearly inferior to another. Ask yourself why it’s there. Chances are, it’s not there for you. It’s there for them. Luna: And if you can spot the decoy, you take back control of the decision. You stop being the product and start being the consumer. Lucas: Exactly. It’s a small shift in perspective, but it changes everything. From now on, whenever you see three choices, remember the coffee box in the grocery store. Remember that the middle option is often just a mirror reflecting what the seller wants you to see. Luna: Do you think we’ll ever get tired of these manipulations, or will they just evolve into new forms of bias? Lucas: They will evolve. The decoy effect is just one tool in a vast toolbox of cognitive biases. But the principle remains the same. Awareness is the antidote. As long as we question the structure of the choice, we remain free to choose.
