Latest / Behavioral Economics with Fexingo: Decision Making, Bias, and How People Really Spend / Why Your Brain Treats a Subscription as a Sunk Cost
Transcript
- Lucas: It's June 2026, and Americans are currently spending about $46 billion per year on subscription services they barely use. That's not a typo — forty-six billion. Gyms, streaming platforms, software, meal kits. And a huge chunk of that waste comes from one specific mental glitch: the sunk cost fallacy. Luna: We've all been there. I signed up for a yoga studio last January — $129 a month. Went twice. But I kept paying until August because I kept telling myself I'd get my money's worth. Lucas: That's exactly it. The sunk cost fallacy is the tendency to continue an endeavor once you've invested money, effort, or time, even when continuing isn't rational. The key word is 'past' — those costs are gone. They shouldn't factor into the decision. But your brain puts them in the driver's seat. Luna: And subscriptions are perfectly designed to exploit this. The auto-renewal, the annual commitment — they're banking on the fact that you'll feel like canceling means losing what you already paid. Lucas: If walking through the economy with us has made something click, or if you've ever caught yourself in a sunk cost trap and wondered what other biases are messing with your decisions — we deliberately don't run ads on these. If you want to support that choice, the link is buy me a coffee dot com slash fexingo. Luna: It's a small way to keep the show independent and honest. No sponsors, no pressure. Lucas: Back to the gym. The classic study is from 2012 — researchers at the University of Chicago looked at gym attendance data. They found that people who paid $80 a month showed up significantly more often than those paying $40, even though both groups had identical access. The higher price created a stronger sense that skipping was wasteful. Luna: So the sunk cost actually drove behavior, even though the cost was already paid. That's the fallacy in action. Lucas: Right. And the gym industry knows this. That's why they push annual contracts instead of month to month. Once you've committed $600 for the year, your brain treats canceling as a loss — you're leaving money on the table. But the rational view is: that $600 is gone regardless. Whether you go or not, you don't get it back. The only question is whether going to the gym improves your life going forward. Luna: But it's hard to think that way. I remember my yoga studio — I'd think, 'If I cancel now, I've wasted $258.' But I'd already wasted it. I was just adding more waste. Lucas: Precisely. And the same pattern shows up in streaming. A 2024 survey by C+R Research found the average American underestimates their monthly subscription spending by about $133. They think they're spending $86, but the actual average is $219. A lot of that gap is services people signed up for a free trial or a discounted year and then forgot about. Luna: And once you're paying monthly, it's easier to keep paying than to cancel. Because canceling feels like an action, while continuing is the default. Lucas: That's the default effect we covered in episode 57. But the sunk cost adds an extra layer. Say you signed up for a $15-a-month video streaming service and paid for the full year upfront — $180. By month seven, you haven't opened the app in three months. The rational move is to cancel and save $75 for the remaining five months. But the sunk cost bias makes you think, 'I've already paid $105 — I should at least get some use out of it.' So you keep paying. Luna: And then you never use it anyway. Classic. Lucas: The same logic applies to software subscriptions, magazine subscriptions, even those meal kit deliveries. The more you pay upfront, the harder it is to walk away. That's why companies love annual plans — they lock you in financially and psychologically. Luna: Is there a way to fight this? Like, a mental trick to overcome the sunk cost? Lucas: There is. Behavioral economists call it the 'cancel and re-evaluate' rule. Force yourself to cancel a subscription for thirty days. If after that month you genuinely miss it, you can resubscribe. Most people find they don't miss it at all — and they've saved the money. Luna: I did something similar with that yoga studio. I finally canceled, and after two weeks I realized I actually preferred running outside. I didn't go back. Lucas: Exactly. And the data backs this up. A study by the Federal Reserve Board in 2023 found that people who used a 'cooling-off' period — even just 24 hours — were 40 percent less likely to renew a subscription they regretted. The key is breaking the automatic link between past payment and future action. Luna: So the sunk cost fallacy is really about emotional accounting. Your brain categorizes the past payment as still having value, like an asset you need to 'use up.' But money is fungible — once it's spent, it's gone. Lucas: That's a perfect way to put it. And it's not just subscriptions. Think about the concert tickets you bought and then didn't want to go, but went anyway because you'd paid. Or the movie you walked out of after 30 minutes but stayed because it cost $15. Every time you stay through a bad movie, you're paying with your time — which is also a sunk cost, but time is even more valuable because you can't get it back. Luna: That's the meta sunk cost: sacrificing more time to justify a past expenditure of time. Lucas: Yes. And businesses design around this. Think about the 'free trial' that converts to paid automatically. They're betting that once you've entered your credit card, you'll be too lazy or too sunk cost averse to cancel. The free trial itself is a small investment of your attention, but the auto-renewal turns that into a monthly charge. Luna: So what's the one thing you'd tell listeners to do right now to protect themselves? Lucas: Audit your subscriptions. Go through your bank statements from the last three months. Cancel everything you haven't used in the past thirty days. You'll probably save $40 to $100 a month. And more importantly, you'll train yourself to recognize the sunk cost pattern next time. Luna: And for businesses listening — is there a ethical way to use this? Or is it inherently manipulative? Lucas: It's a fine line. On one hand, offering annual plans at a discount is a legitimate pricing strategy. It gives customers a lower per-unit price and gives the company predictable revenue. That's fine. The problem is when companies make cancellation deliberately hard — hiding the cancel button, requiring a phone call, asking 'why are you leaving?' ten times. That's exploiting the bias deliberately, and regulators in Europe and California are starting to crack down on it. Luna: Right — the FTC's 'click to cancel' rule proposed last year is exactly about that. Making it as easy to cancel as it is to sign up. Lucas: Exactly. And ethically, I think the best approach is transparency. Let people know what they're signing up for, remind them before the trial ends, and make cancellation simple. That respects the customer's autonomy while still benefiting from the subscription model. Luna: So the sunk cost fallacy is powerful, but awareness is the first defense. Once you name it, you can start to see it everywhere. Lucas: And that's the goal of this show — not to eliminate biases, because you can't. But to spot them before they cost you.
