Conclusion and Your Reflection Question
SPEAKER_00Hi everyone! Welcome to Personal Finance with Molly, where we talk about all things personal finance. I am your host, Molly Ford Coates. Let's dig in. Hey, welcome back. Grab your coffee or tea or water or something else. I don't judge. And let's talk about something that I think quietly drives many of our financial decisions. Here's a question to open us up. Have you ever stood in a coffee shop, ordered a$7 latte without even glancing at the menu price, and then the next day gone back and forth for 45 minutes about whether a$30 online course was worth it? Or maybe you spent$200 on a dinner without thinking twice, but cringed when your phone insurance came up for renewal at$9 a month. If any version of that sounds familiar, you're not bad with money, you're not undisciplined, you're not even irrational. Not really. You are, however, human. And humans have a brain that was wired for survival on the savannah thousands and thousands of years ago, not for navigating Amazon Prime or subscription services and outlet mall pricing psychology. So today we are going deep on a misunderstood idea in personal finance. The difference between cost and worth. These are not the same thing, friends, but your brain, your beautiful, ancient, pattern-seeking brain, treats them like they are. And that confusion, well, it is costing you. Let's dig in. Before we get into the fun stuff, like the biases and the quirks and the places where we all leak money without knowing it, let me give you a quick traditional finance versus behavioral finance. Because this is going to be our lens for the whole episode, talking through the lens of behavioral finance. So, traditional finance, the stuff that gets taught in textbooks, traditional finance assumes that people are rational actors. You see a price, you compare it to your budget, you make a logical decision. You know, supply and demand, marginal utility, efficient markets, all of that stuff. Behavioral finance says, yeah, no. People are not rational. We are predictably irrational. We make the same mistakes over and over in patterns that researchers have been able to map and study since the 1970s. The founding fathers of behavioral finance, Daniel Kahneman and Amostaversky, basically broke economics by proving with data that humans violate the rules of rational decision making constantly, not randomly, predictably. The same way for the same reasons again and again. And Richard Thaler, who won the Nobel Prize in Economics in 2017, took that work and applied it to personal finance decisions specifically. How we save, how we spend, invest, how we avoid and rationalize our way through money. And what all of them found at the core is that our perception of value, which is what something is worth to us, our perception of value is not a fixed objective thing. It shifts, it warps, it gets manipulated by context and framing and comparison and emotion and timing. So when we talk about cost versus worth today, we're not talking about accounting. We're talking about psychology, the story your brain tells you about a price and how to start questioning that story, friends. Okay, first big concept. And this one, once you see it, you cannot unsee it. It's called anchoring. Here's how anchoring works. Your brain, when it encounters a price or a number, uses that first number as a reference point or an anchor for every judgment that follows. Even if that first number is completely arbitrary, even if someone just made it up. Tversky and Kahneman demonstrated this with a famous experiment. They spun a wheel of fortune, rigged it so that it would land on either 10 or 65 in front of participants. Then they asked, what percentage of African countries are in the United Nations? Well, friends, the people who saw the wheel land on 65 guessed significantly higher than the people who saw it land on 10. A random number from a spinning wheel changed their estimate of a completely unrelated fact. Now, bring that to your wallet. Let's have an example. You walk into a store, there's a blazer on a rack, the tag says$800, marked down to$350. Suddenly,$350 feels like a steal, doesn't it? You are anchored to$800. But here's the question nobody asks. Was that blazer ever really worth$800? That original price might have existed for a single day in a single location for the sole purpose of making$350 feel reasonable. Retailers, especially in clothing, furniture, and electronics, are masters of anchor pricing. The original price, quote unquote, is often a psychological fiction designed to warp your sense of worth. This shows up in real estate too. The listing price of a house anchors negotiators. Studies have found that real estate agents, when given a property to evaluate, gave significantly higher estimates when the listing price was artificially high, even when they were told to ignore the listing price. So what's the antidote to anchoring? It's a simple but difficult question. What would I think this is worth if I didn't know the original price? Strip that anchor away. If you walked into that store and saw a blazer on a rack with no original price, no markdown, just a$350 tag, would you still buy it? If yes, great. If suddenly that number feels different, you just caught your brain in the act, friends. Let's talk about another thing, something that I find both fascinating and also slightly maddening, and that's called mental accounting. Mental accounting is a concept developed by Richard Thaler, and the core idea is this: we treat money differently depending on where it came from, even when the money itself is identical. Here's the classic example. Imagine you get a tax refund, and we're in April right now, so let's talk about tax refunds. Imagine you get a tax refund. Let's say$1,400. How do you spend it? For most people, that money gets treated very differently than a regular paycheck. People are more likely to splurge on a vacation or a new gadget or a luxury item with a tax refund than they would be if that same$1,400 just showed up in their regular salary. But here's the thing, friends: it's the same money. Your landlord doesn't care whether your rent came from your paycheck or your tax refund. The dollar is the dollar. But your brain has put it in a different mental bucket. The tax refund goes into the bonus account, and bonuses feel like play money. The same thing happens with gambling winnings or birthday money or cash you find in an old jacket. We treat windfall money as less real than earned money, and so we protect it less carefully. And friends, mental accounting cuts the other way too. Think about how differently you treat a pre-budgeted category versus an unbudgeted one. You might budget$20 or$200 a month for groceries and agonize over whether to buy the fancy cheese, but then turn around and spend$80 on a spontaneous Uber Eats order or DoorDash without blinking because it came out of a different mental account. And you might tell yourself, well, that's just a night off. The result of this? We chronically undercount the total cost of a lifestyle because we're keeping score in multiple separate ledgers instead of one. And here's where it connects to our cost versus worth theme today. Mental accounting distorts worth by category. We don't ask, is this worth$80 of my money? We ask, is this worth$80 of my dinner budget? And sometimes those budgets are a fiction we tell ourselves. So one practical move, friends. Once a month, collapse your mental accounts. Look at your total spending as one number. Take the whole picture in. And not to shame yourself, friends, but to get accurate data on where your worth judgments are actually landing. All right, here's one of my favorite pieces of behavioral finance research, and it comes from researchers Drazen Prelick and Duncan Simister. They ran a study where they auctioned off tickets to sold-out sports events. Half the participants were told they'd pay with cash, the other half were told they'd pay with a credit card. Guess what, friends? The credit card group consistently bid more, and sometimes significantly more. Well, why? Because paying with a credit card reduces what Prelick and Simister called the pain of paying. The pain of paying, the physical and psychological sting of actually handing over money, of watching your cash leave. And that pain is dulled when the transaction is abstract, like a swipe or a tap or a number on a screen. The money then doesn't feel as real. This is connected to a broader principle from Kahneman and Tversky's prospect theory, which is loss aversion. You know I love saying this, loss aversion. We feel the pain of losing something roughly twice as intensely as we feel the pleasure of gaining the equivalent amount. So spending money, which is technically a loss, triggers a real psychological response. And our brains will go to impressive lengths to suppress that response. Tap to pay, one-click ordering, subscription services that bill you invisibly every month, free trials that auto-renew. All of these reduce the pain of paying, which sounds nice, but when paying hurts less, we tend to do it more. And we evaluate worth less carefully. And by the way, there is an inverse version of this. Some people go the other direction. They feel the pain of paying so acutely that they underinvest in things that would genuinely transform their lives. The$500 coaching session, the$1,200 ergonomic chair that would end three years of back pain, the estate lawyer you keep putting off because the consult fee makes your stomach hurt. When the pain of paying is high, our perception of worth collapses. Not because the thing isn't valuable, but because the financial transaction itself feels like a loss, and we are wired to avoid losses. So, friends, here's a reframe, and here's a reframe that helps me too. So instead of thinking, I'm losing$500, try thinking I'm trading$500 for something. That trade might be a great deal or a bad one, but framing spending as a trade rather than as a loss gives your prefrontal cortex a seat at the table instead of letting your amygdala run the whole meeting. Now, let's spend a few minutes on a cluster of related biases that all do the same thing. They inflate our perception of worth in many ways that have nothing to do with actual value. First one, the sunk cost fallacy. Sunk cost fallacy. You are 20 minutes into a terrible movie. You paid$18 for the ticket. Do you leave? Most people don't because they've already paid, and walking out feels like wasting the$18. But here's the rational reality. That$18 is gone whether you stay or go. Staying doesn't recover it. The only question is: how do you want to spend the next two hours of your life? The sunk cost fallacy causes us to attach too much worth to things we've already invested in, whether it be money or time or energy or identity, even when the rational move is to walk away. We stay in bad investments because we've already contributed. We keep subscriptions we don't use because we paid the annual plan. We hold on to underperforming stock because selling it makes the loss real. The sunk cost fallacy turns past spending into emotional hostages that hold our future decisions captive. The antidote is what economists call a zero-based mindset. Imagine you're starting fresh right now. You have no history with this investment or this subscription or this relationship or this situation. Would you choose to get into it today? If the answer is no, the sunk cost is not a good enough reason to stay, friends. Here's the second. IKEA effect. And this one is delightful and also quite human. So research by Michael Norton, Daniel Mochin, and Dan Arielli found that people value things more when they've made them themselves, even when the quality is objectively lower. They had people build IKEA furniture and origami cranes and then asked them to value their creations. Well, guess what? People overvalued their own creations significantly, sometimes asking others to pay as much for their origami swan as they'd pay for an expert's work. The IKEA effect shows up in our finances in subtle ways. We overvalue businesses we started, or the portfolios we built, or the budgets we designed, not because they're actually better, but because we made them. This can make us resistant to getting help or advice or outside perspectives because accepting them means admitting that our creation isn't as good as we think. It also means that we inflate the worth of effort. We feel like because something cost us a lot of hard work, it should have a high value. But the market doesn't pay for your effort, friends. It pays for results. A painful, laborious DIY renovation might feel worth more to you than hiring a contractor, but the hours you spent are not automatically recovered in home value. Know where your own labor is genuinely worth investing and where you're just making things harder because it feels more valuable to do it yourself. And I want to touch on one more concept before we get to the practical framework. And it's one that doesn't get enough airtime. Opportunity cost neglect. Behavioral research consistently shows that people are terrible at factoring in opportunity cost. And opportunity cost is what you give up in order to get something. So when you're deciding whether to buy a thousand dollar guitar, you're probably thinking, do I want a guitar? Is this a good guitar for$1,000? What do the reviews say? What you're probably not thinking is, well, if I don't spend$1,000 on this guitar, what else could I do with it? What does$1,000 invested at 7% annual return look like in 20 years? And spoiler alert, it's about$4,000. What experience or trip or problem could$1,000 solve instead? Research by Shane Frederick and his colleagues found that when people are explicitly prompted to think about what else they could do with the money, what economists call the opportunity cost cue, they make significantly more conservative purchasing decisions. Friends, this isn't about guilt tripping yourself out of every purchase. It's just about completeness. A spending decision made without considering alternatives is like picking a restaurant without knowing what else is on the street. You might be happy, but you're not making a fully informed choice. The point is not that you should never spend$1,000 on a guitar. The point is if that guitar genuinely adds ongoing joy and skill and creative value to your life in ways that$1,000 invested would not, that's a completely valid call. But make it consciously, make it with your eyes open. Worth, at its most honest, is measured against everything else you could do with the same resource. Okay, we've spent the last 10-ish minutes inside your brain identifying all the ways it quietly distorts your sense of what things cost and what they're worth. We talked about anchoring, mental accounting, the pain of paying, sunk costs, the IKEA effect, and opportunity cost neglect. Now, let's turn it around. What can you actually do with this? I want to give you a framework I call the worth framework. It's just three questions. You don't need to ask them for every cup of coffee, friends. That way lies paralysis. But for any significant purchase, investment, or financial commitment, these three questions will cut through a lot of the noise that your brain generates. Here they are. Question one. Would I pay this price if I didn't know the original price? This is your anchoring check. Strip the markdown and the comparison and the but the other one was$800. You're looking at a thing and it costs this amount. Full stop, friends. Does it pass the test? This question is particularly powerful at outlet malls or during sales. And whenever you hear yourself saying the word deal, so question one, would I pay this price if I didn't know the original price? Here's question two. What would I have to give up to afford this? And is that trade worth it? This is your opportunity cost check. Be specific. If I spend$300 on this, what does$300 represent in my life right now? Is it one month of extra debt payment? Is it a weekend trip I've been wanting to take? Is it a three months of a savings goal? When you name the trade, the decision gets a lot clearer. You're not just choosing the thing, you're choosing it over its alternatives. So that was question two. What would I have to give up to afford this? And is that trade worth it? Question three One year from now, will this have compounded in value or evaporated? This is your time horizon check. Some purchases genuinely compound, like courses or tools or Or experiences that expand your skills or relationships, or health investments, a good mattress, a therapist, books. These are not expenses, they're investments in a slightly different account. Other purchases evaporate. Fast fashion, trendy gadgets, impulse decorations. Not wrong to buy, friends, but just be honest. You're buying something that will have essentially zero value in 12 months. This question doesn't mean only buy things that appreciate in dollar value. I am not saying that, friends. It means be honest about whether this is an investment in your future or a transaction with your present moment emotional state. If the answer is it'll evaporate and I'm okay with that, and I've answered questions one and two honestly, and I can genuinely afford it, then buy the thing. Spend money on joy. That's what it's for. But spend it consciously. So those are your three questions. That's the worth framework. Would I pay this price if I didn't know the original price? What would I have to give up to afford this? And is that trade worth it? And one year from now, will this have compounded in value or evaporated? All right, here's the truth that I want to leave you with today. Most personal finance advice treats your spending problems as a math problem. Track your numbers, make a budget, cut the subscriptions. And friends, those things do matter, yes, but they are the surface. Under the surface is a human brain that is running decades of software designed to hunt, prey, avoid predators, and find status in a tribe. That brain is now navigating Black Friday offers, the Amazon's one-click button, and it is not well adapted for that environment. The gap between what things cost and what they're genuinely worth to your life, that gap is not closed by discipline. It's closed by awareness. By catching your brain in the act, by asking the right questions before the swipe, not after the regret. You don't have to be a behavioral economist to use this stuff. You just have to slow down long enough to let your prefrontal cortex catch up with your amygdala. One breath before the big purchase. One question before you tap to pay on something significant. One honest conversation with yourself about whether this is worth it. Where worth means the full, honest, opportunity cost included, anchor free version. That's the work. It's quiet, it's internal, and over time, friends, it changes everything. Before you go, I have a reflection question for you. Think of the last purchase you made that you later regretted. Not just I shouldn't have done that. Go deeper. Which bias was running the show? Was it an anchor? Was it a mental account? Was it the pain of paying or not feeling it? Sunk cost thinking? Name the bias. Name it and take away some of its power. You got this, friends. Hey, thanks for listening to Personal Finance with Molly.
