Latest / Behavioral Economics with Fexingo: Decision Making, Bias, and How People Really Spend / Why Your Brain Treats a Subscription as a Sunk Cost Trap
Transcript
- Lucas: So I've been looking at my bank statements lately, and I realized I'm still paying for a premium meditation app that I haven't opened since January. Luna: Oh, I have one of those too. Mine's a language learning app. I think I did three lessons in 2024. Lucas: Right, and the question is — why don't we cancel? It's only a few bucks a month. The rational thing is to cut the loss. But something in our brain says, 'I've already paid, I should use it.' Luna: That sounds like the sunk cost fallacy applied to subscriptions. But with a twist, because it's recurring. Lucas: Exactly. This is what behavioral economist Dan Ariely calls 'subscription debt.' The idea that when you sign up for a recurring payment, you feel a psychological obligation to extract value from it — even if you're not using it. The past payment creates a mental anchor. Luna: So it's not just that I lost five dollars. It's that I feel like I owe it to myself to get five dollars' worth of meditation out of the app. Lucas: Precisely. And that feeling can keep you subscribed for months or even years. One study from Stanford looked at gym memberships. They found that people who paid a monthly fee attended more often than those who paid per visit — even when the monthly fee was higher overall. The monthly members felt they had to 'use it up.' Luna: But that's the trap. The money is already gone. Whether you go to the gym or not, you're not getting it back. The rational choice is to decide based on future value, not past costs. Lucas: Right, but our brains aren't wired that way. The subscription model actually exploits this bias. Companies know that once you're in, you're likely to stay — not because you love the service, but because you feel a sense of debt to your past self who paid. Luna: And they make cancelling deliberately annoying. You have to call, or navigate a maze of menus. That adds friction to the decision. Lucas: Absolutely. Think about the streaming services. A 2022 survey found that the average American subscribes to four streaming platforms but actively uses maybe two. Yet cancellation rates are surprisingly low. The 'subscription debt' keeps us hooked. Luna: There's another layer too. Some services use what's called 'the endowment effect.' Once you've paid, the subscription feels like part of your identity. 'I'm a premium user.' Cancelling feels like losing a status. Lucas: That's a great point. And it ties into mental accounting. We treat subscription money as a separate budget category — almost like a utility bill. So we don't evaluate each subscription on its merits. We just lump them together as fixed costs. Luna: So how do we break this? I've started doing a 'subscription audit' every quarter. I list every recurring payment and ask: 'Did I use this in the last 30 days? If not, cancel.' Lucas: That's a solid tactic. Another one is to reframe the mental account. Instead of thinking 'I've already paid,' think 'I'm paying again next month. Is it worth it?' That shifts the focus from past to future. Luna: Some apps actually help with that. There are services that track your subscriptions and remind you when you're not using them. But that's another layer of cost. Lucas: Yeah, and it's funny — you could end up subscribing to a subscription manager. The irony. Luna: Right. So the core insight is: recognize that the sunk cost is gone. Your future self isn't obligated to the past. Lucas: And that's the behavioral economics lesson. Let's talk about a specific example: Peloton. After the pandemic boom, they saw a huge drop in usage but subscription revenue stayed sticky. People kept paying because they felt they owned the bike, and the subscription was part of the investment. Luna: That's the sunk cost plus the endowment effect. 'I spent $2,000 on this bike, so I have to keep paying to justify it.' But the bike is still there whether you subscribe or not. Lucas: Exactly. And Peloton's retention rates were remarkably high even as usage plummeted. That's the power of subscription debt. Luna: So how do companies design for this? They make the initial sign-up easy, often with a free trial. Then they auto-renew. And they send you emails saying 'We miss you' instead of 'Would you like to cancel?' Lucas: Right. The free trial is a classic. You feel like you've already committed, so when the trial ends, you're more likely to pay than to cancel. It's the 'door-in-the-face' technique reversed. Luna: And once you're paying, they make the content or features just good enough that you don't want to lose them. But not so good that you actually use them a lot. It's a sweet spot for retention. Lucas: You know, speaking of small recurring costs — a couple of dollars a month is genuinely what keeps shows like this going. If walking through the economy with us has made something click, consider throwing a few bucks our way at buy me a coffee dot com slash fexingo. Luna: Yeah, it really adds up. Even one coffee a month helps us keep the episodes ad-free and focused on the ideas. Lucas: Exactly. So back to subscriptions — there's also the phenomenon of 'subscription stacking.' People sign up for multiple services, each cheap individually, but collectively they add up to a significant monthly bill. And we don't notice because each one is a separate mental account. Luna: That's a great term. I've seen people spend over $100 a month on subscriptions they barely use. That's $1,200 a year. That's a vacation. Lucas: Absolutely. And the companies know that. They price individual subscriptions low enough that you don't think twice. But the aggregate is huge. Luna: So what's the antidote? Other than the audit, is there a mental trick? Lucas: One trick is to imagine you're subscribing for the first time today. Would you sign up at this price for this service? If not, cancel. That reframes it from a sunk cost to a fresh decision. Luna: I like that. It's like the 'last chance' test for purchases. But applied to subscriptions. Lucas: Right. And another thing: beware of annual plans. They lower the monthly cost, so they feel like a bargain. But they lock you in for a year, increasing the sunk cost. If you end up not using it, you've paid more overall. Luna: So the best strategy is month to month, and cancel early if you're not using it. Don't let the sunk cost trap you into paying for something you don't value. Lucas: Exactly. And that's the key takeaway: your past self's payment is irrelevant. Your future self's value is all that matters. Luna: I think a lot of people will recognize themselves in this. I know I will. I'm going to go cancel that language app right after this. Lucas: Do it. And then maybe start that meditation app again — but only if you actually want to meditate, not because you feel obligated.
