2:17All right, folks. Welcome to the Investing for Beginners podcast. Today, Andrew and I are going to break down some behavioral finance. We're going to talk about probably the most important thing about investing, the six to 10 inches between your ears, depending on how big your head is. That gray matter in your head is probably way more important than we give it credit for. And what we're going to do is we're going to talk through a little bit some ideas that we picked up from Charlie Munger's famous speech, The Psychology of Human Judgment. He is probably definitely one of the leaders in this area and idea.

2:56And Andrew and I were kind of revisiting this speech. And I got to tell you, it's a masterclass and you should read it slash listen to it as much as you possibly can. There is so much to mine from this. So we're just going to, we may not do it justice, but if you want to go to the source material, by all means, definitely check it out. So Andrew, let's start talking about the psychology of human misjudgment and some biases and maybe some things that we have learned along the way that could help people. Yeah. I mean, I think when we think about what's in our brain, you would hope for a nice organized library or a stack of textbooks of all the right investing books.

3:38Really, I think it's more like that Pixar movie where we just have a bunch of different colored monsters who all represent different emotions. And that's really what drives our decisions. and Charlie knew this as well as anybody and he was able to mitigate it and find great success despite the fact that it's hard to control emotions we can be very emotional and I love the way he described there's like two versions of the speech I guess so I don't know which version I'm referring to but he talked about how not a lot of people would like the idea of him basically skimming three psychology books and then having the nerve to make a whole speech about it.

4:21And there will be a lot of haters who look at him for displaying so much disregard for conventional wisdom while, quote, popping off on the subject in which he had never taken a course. And I love that he just lays it out like that and then proceeds to go on and make the speech anyway, which, like you said, has so many gems of wisdom and so many things that the more you think about like, wow, I guess I do have tendencies to do that. And wow, I better try to be aware that I can have those tendencies because a lot of those things can make us not as good of investors as we would like to be. And it's not just going to come naturally.

5:04I'm not just going to frolic through the fields of accounting books and spreadsheets and come to this great awareness of how I can make better decision making a speech like charlie munger's can help you get there so i like you said i don't think we'll do it much justice but hopefully we can we can uh telephone game at least one or two insights and i wholeheartedly agree with what you said like go to the source material because it is fantastic yep yep it is and uh little side note you can download the song as a song in Spotify and it's about an hour and 15 minutes. I used to listen to it years ago and Andrew and I were just actually downloading it a few minutes ago.

5:47So it is available on Spotify. So if reading is not your thing and you want to listen to it on a walk, for example, highly, highly recommend it. Put it on a repeat and listen to it for like months straight. Yeah. All right. So maybe not that, but let's talk about some cognitive biases that drive human behavior. I think a biggie and one that's probably most people are familiar with is something called confirmation bias. When I say those words, what does that mean to you? Confirmation bias is I'm going to seek out the information that I've already made my mind up about. And I'm going to ignore any other information that might be trying to tell me that I'm actually wrong.

6:30And we all do this. What it can do, obviously, hopefully, it is obvious. But if you've made up your mind before you've actually learned what the real reality of a business is, you'll make a lot of poor decisions. So rather than approaching a stock to say, I love this stock, and you've decided you love it on minute three of reading about the company, at that point, it doesn't matter how much more research you do. If you have confirmation bias, you're not actually researching or trying to find the answer. You're just finding things that confirm and make you feel like you're already correct. And you see this in politics all the time.

7:10And unfortunately, you see it in the stock market all the time. And it's not that easy. It's not as easy as finding your favorite company or finding the stock that everybody loves and just automatically thinking that that's going to be the next optimal return over the next five to 10 years. It's not that easy. And if you can get ahead of confirmation bias, you can become a much better stock picker. Yeah, for sure. How would you recommend people maybe take a stab at disconfirming confirmation bias? How can they avoid it, do you think? One of the things, which is hard because investing can be a solo game, But I like to, in our conversations with each other, I like to tell you, hey, I think I'm drinking the Kool-Aid here.

8:01Tell me what I'm missing. Because once I've drank the Kool-Aid, it's too late. And so having somebody who can provide you with outside perspective. so I guess to sum that up I'm seeking opposing opinions and this doesn't mean I'm necessarily wrong but it means I need to see what other people who haven't drunk the Kool-Aid are thinking about and what lens are they seeing about a company because I don't think every stock pick is different but I would say if you want to do a majority of the time a good stock pick, you should probably feel a little bad and a little good about. If you feel all good about a stock pick, you probably haven't done your research or you are buying a stock that's really expensive.

8:53Those would be the things I think trying to balance the emotions and trying, if you're feeling really romantic in a way about a stock, go out and intentionally look for reasons to not like a stock. Because you can always find bears and bulls on any company. Yeah, I love that. And I think that, to me, that's probably one of the better ways to do it is try to include opposite opinions of what yours is so that you can get input that may help dissuade you from drinking the Kool-Aid, so to speak, or at least give you a viewpoint from a different angle on something that you may not have considered. And that's why reading others' writings about a particular business can be helpful, especially when you're closer to the point of potentially making a decision and then looking at what the opposite side has to say about that.

9:49I know I've read about people that will actively seek out short reports or will seek out different information that will help kind of counteract their confirmation bias. and so they can try to look at the other side because it's so easy. It's so easy to drink the Kool-Aid and fall in love with a business or a CEO or a product and just get blindsided and just keep looking. Every information, seems like everything you look at goes, yep, yep, yep, yep. And that could be a dangerous place. And so it's really hard to keep an open mind and that's why it's so important to try to get outside of the echo chamber either in your own head or in the circle that you're operating in to get other points of view because that can be so enlightening.

10:39Well, the algorithm is actually designed to perpetuate your confirmation bias. There's a great documentary. I recommend it to everybody, even if you're not picking stocks. Do you remember what the name of it is? Social Experiment or something? Yeah, Social. Oh, gosh, what was it? Yeah, it was about the social. It was about meta. I think it was Facebook at the time, but Facebook, LinkedIn, Instagram, Twitter, like all those and how they were designed. Yeah, I'm blanking on the name of the, it'll come to me at 2.40 this morning. But yeah, it was a great show on Netflix for a long time. And it was really, it exposed how those algorithms work and how they're designed and how addictive they can be.

11:25Yeah, and also how it led to a lot of other riots and stuff that you see in politics and during elections and all this, and just all, like you said, the echo chambers. I'll give a silly example, but it's true. so I'm from Southern California I grew up on In-N-Out and I doesn't matter how many french fries that five guys will put in my bag that overflows my cup I do not care how many they will put in my bag I am an In-N-Out guy if I'm on Instagram and you are showing me you eating an In-N-Out burger I'm all about it I'm watching that and for some reason I seem to see more and more In-N-Out videos on my Instagram feed.

12:11So I am seeing all this confirmation that in fact, In-N-Out is the better burger chain. And by the way, I actually don't see much Five Guys in my Instagram. So that must mean, in fact, I am correct that In-N-Out is better than Five Guys. So would you look at that? The internet has given me great information. Affirmation bias. Thank you. 101.

12:41All right. So let's move on to the next confirmation bias that Charlie talked about, and that's the authority bias. The way I would, I guess, define it is you give an overweighted perception of somebody you look up to's opinion. So a perfect example for me would be Charlie Munger, Warren Buffett, Michael Mobison, Oswalt DeModerin, Monish Pabrai, all these people that I've looked up to, their opinion probably drives more of my bias on what they think because I've put them on a pedestal, so to speak. And Jimi Hendrix for the guitar, Eric Clapton for the guitar, Steve Ray Vaughan for the guitar, all those people, you put them on a pedestal and it's very easy to give them outsized authority.

13:32What they say is going to have a huge impact on how you think and how you behave. And so that's something you definitely have to work against. And it's hard. It's very difficult. So I'll flip it on you now. How do we fight against that? Because that's really hard, especially in investing where these guys have been so successful and they've weathered many cycles and they're obviously very smart guys. How do you make sure that we're not falling into this? I wouldn't say I'm perfect at this. This is a work in progress, shall we say. And one of the things for me is trying to read other people's opinions and to set aside those influences and try to learn from other people and then try to incorporate those other people's opinions.

14:26and maybe a perfect example is we just had David Gardner from The Motley Fool on the show. And he has some Buffett-isms in him, but he has other not, very decidedly not Buffett-isms in there. And so after reading his book and listening to your great interview with him, there's a lot of things you can pick up from him. He's been very successful as an investor. And so you have to decide, I have to decide, are some of the things that David proposes are things that fit with me personally, with my emotional state and with my mental state and how I can invest and balance that with what Charlie and Warren have taught me all these years.

15:11And so I think it's a little bit about trying to balance your influences. And so for me, the way I try to work through it, I'm not saying this is the ideal way to do it. And hopefully you have a better way. But the way that I do it is I try to read other people's writings and try to think about their influence and how that could impact taking the base of what I've learned from these other people and try to add this and try to make it my own, so to speak. I'm relating this to the music thing because that's what you have to do when you're a musician. You imitate. At the beginning, you don't know what you're doing, right?

15:48So you have to imitate Jimmy. And you have to imitate Steve Ray Vaughan or B.B. King if you want to be a blues guitar player. You have to mimic those guys. You have to learn what they play, play their solos note for note, all this kind of thing. But over time, you start to pick up other influences. Because Steve Ray Vaughn or Steve Vai or Joe Satriani were nothing like those guys. But then you start to pick up what they're doing and then it kind of becomes your own, so to speak. And so maybe that's, I'm not sure if that's not a great analogy, but that's what I've kind of tried to do with investing in those authority figures for me.

16:23Yeah, I love that. I mean, I don't think I have a better solution than that. my tendencies have been to think that history will repeat closer than it ever does. And so I guess one of the ways, I don't think I've actually tried to do this consciously, but now that I realize it probably should be a more conscious effort is just to be more, because when I started, I was all about history, history, history. Like one of the things I remember picking up very early on as an investor. And just if you read books in general, this tends to be true, is the idea that the best books are the ones that have been the best sellers the longest.

17:06Because there's just so many books that just come and go, and they come and go, and they come and go. So if you really want to read the best material, it tends to be the material that's been the best seller for 50 years. Benjamin Graham, Joel Greenblatt, right? Like these guys who knew what they were talking about, And their wisdom is timeless. So I think I definitely spent too much time in that world and not enough time in today's world. And when I started to take the advice that you would prescribe on our show and that we would talk about of, hey, read a lot of 10Ks, listen to our earnings calls, get yourself out of the past and look at what's happening in the present, to me that helps because I think I emulated a little bit too closely whatever great investors were doing in the past, and it's a different world.

17:59So you can't just take that authority figure and how he invested and duplicate it today because it's a different world. It's not going to work. Even though a lot of the principles will stay the same, you can't follow it too closely. You can't let this bias get to you. That was one way, I think. In hindsight now, and I was worried because you kind of put me on the spot, But I think in hindsight, that was something that was a way to kind of counteract that. And I think it could be helpful if people struggle with that today. Yep. Yep. For sure. I think it's a real easy bias to fall into under, especially in the investing world, especially when you're newer to the whole investing game is to find somebody that really resonates with you.

18:42and to really, I'm not saying it's a bad thing, but at some point you have to kind of, you have to start to try to be your own person because the way Peter Lynch invests or the way that Bill Ackman invests may not fit your personality. And so that's where this, you have to start working past that bias. And the reason why Charlie brought these all up are because these are all things that we all struggle with. And he's trying to point out ways that we can potentially move past those so that we can try to be our own person. And ultimately, that's what he's trying to get at. All right. Let's move on to the next one, which is social proof.

19:21This is in this day and age of social media, this is very dangerous. Yeah. How would you describe it, I guess, in today's day and age? Because maybe he even described it a little bit differently. I don't know if this... I'm pretty sure the speech was before the internet. So how would you describe it in today's day and age? today's day and age, I would say that it really comes down to, well, so-and-so did this, or so-and-so said that, or I saw so-and-so do this on Instagram, so it must be a good thing, or it must be right. It would be a little hanging fruit to throw Alex Hormozzi under the bus, because he's one of the largest followed people, and a lot of people treat what he says as gospel.

20:03and I'm not saying he's wrong. I don't read him. I don't listen to him. It's not a person I follow, which is fine. But I would say that there's a lot of disciples of his and I think a lot of people, because he says something to do it, that they go out and do it and he has a huge following. So he has a huge influence on people and it could be a dangerous path to follow. Again, if it doesn't fit you and your personality or the way that you want to operate or live your life, and that can make it challenging. I'm not saying it's good or bad, but I am saying that it can be dangerous if it doesn't fit who you are.

20:42Yeah, I agree with that. Nothing to add there. I guess one thing that did pop to my mind is I think there's some social proof in the type of stocks you buy. And I've just noticed this with myself personally is when I have stocks that I've bought recently that everybody can relate to when I tell them about the stock, I get that kind of social proof confirmation or reassurance where if I'm telling you that I bought Progressive Insurance or even something like Crocs, which I've mentioned over and over again on the show, people know those names. And so they'll be like, oh, okay, cool. But if I mention Apulte Group or I mentioned like a B2B.

21:31See, I mean - Something like Simpson Manufacturing, for example. Yeah, yep, perfect. Most people, including me, when you first mentioned it, blank stare. Like, who? Right, yeah. And then you see how it has such a little mind share in my mind now because it's just not, it just sits in my portfolio and grows earnings and doesn't feel as flashy as buying Apple on a dip and being really proud of that moment. So that can be dangerous as an investor because we're not investing, we're not picking stocks to feel good about ourselves or feel like, hey, I can be the cool kid on campus every time I talk to people and tell them the stocks I'm buying.

22:13We should be buying stocks to make money and do it in a safe and consistent and sustainable way. So obviously it's very evident from what I just said that I struggle with this. And I don't know if I have a good solution, but at least maybe being aware that it's there. If I find myself feeling really good about Apple or progressive insurance, that may be, hey, cool the jets and relax and realize, okay, look at it objectively, go back to how you beat confirmation bias, go through those steps and keep that balanced emotion around how you feel about stock. Yeah, that's really good advice. How many times have you either come across an idea or invested in a company and either find out later that some super investor, oh, Bill Ackman bought the same thing?

23:09You know, it does give you a little endorphin rush, you know, because, whoa, hey, you know, I might be onto something here because, you know, somebody that you look up to bought the same thing or vice versa. You're doing research on a company you're interested in. Somehow you come across the fact that some other super investor owns the company that you're interested in. And that can lead to being more open to buying it because you're influenced by by them. One thing we should probably mention about a lot of these biases is sometimes they can stack. So authority bias and social proof can kind of stack on top of each other and then you start adding confirmation bias into all that and it becomes this nice little soup of human emotions that you have to swim through to get to the other side of what you're trying to do.

23:58So it is something you have to be aware of. And I like what you said about we may not have the antidote, but I think if you're at least aware of these, then it can maybe help prevent you or at least give you pause. Okay, so Bill Ackman bought it. How do I feel about that? Do I care? And if you do, then you maybe ask yourself, why do you care? And if you don't care, then okay, move on, check and move on to the next thing. But I think if you understand it, I think it's an easier place to at least try to start to move past some of them.

27:19This is one of my favorites. Oh, really? So please take first serve. Well, I think this is the power of incentives is something that I think once you see it, you can't unsee it. And when you think about what drives behavior for certain things, I think it's very evident in the stock market and it's even more evident in politics. And I don't want to dive into the politics part, but in the stock part of it, you'll see it very, very evidently. The power of incentives will basically drive the behavior. So kind of the way to think about what does this mean is the reason people are doing the thing is because there's an incentive driving them to do it.

28:07They're going to get some sort of reward, whether it's monetary, whether it's public acknowledgement, whether it's internal gratification. There's something that's causing them to push forward an idea or a particular product or project. And an easy way to visualize this is to think about a CEO of a business. If you listen to the earnings report and they're talking about adjusted earnings, for example, and just throw that out there. If they're talking about adjusting earnings for the entire hour of the earnings presentation slash interview with analysts, you can bet your bottom dollar that they're being incentivized.

Read the full transcript

28:51They're getting paid a lot of money on adjusted earnings. And so because that is very important to them, they're gonna focus on that when they're talking to other people about their business. And then they're also gonna focus on that for the operations of the business So they hit those targets for the adjusted earnings, ergo making more money. So this is a simplified example, but it's very evident when you see that kind of thing. You'll see the same thing from the analyst side, for example. Analysts are incentivized to speak highly or positively about a business because they want access to that business.

29:31and so if they air quote tell the truth or say something negative, then they could piss off somebody in investor relations or maybe the CFO or COO and ergo cut off their access. When these analysts talk about companies glowingly, sometimes you have to ask yourself, why are they doing that? When it's so obvious sometimes to us, there's not much positive to say about this company, but here they are, great quarter guys. No, it wasn't. So earnings were down, revenue was down, you know, half of their management team left, you know, in disgrace. Like not a good quarter. Why are you telling them it's a good quarter?

30:16Anyway. So that's why power of incentives to me is really interesting. And I think it's one of my favorites because I think once you see it, you can't unsee it. Love it. So how do you, with that insight, how do you use it to analyze companies on a deeper level? The way that I approach it is I always ask why. So a perfect example is why do I hear the CFO talking about return on equity and the gross margins all the time in their earnings call? Why? Why is that so important to them? Or why is this particular segment of the business so important to them? What's incentivizing them to talk about that?

31:03And so usually what you'll do is then you go to the proxy statement and you find out that they are being compensated in some way, shape, or form by trying to drive that segment or trying to improve that metric of the business. I'm not saying in and of itself that's necessarily bad, but it's always good to ask why why are they why are they pushing so hard on this or why is an analyst why is an analyst hammering on this particular point or why are all of them hammering on this particular point is that something that's really important or are they being incentivized to do this and so that's that's how i try to approach it i'm curious what your thoughts are on all this.

31:44That's really good. I guess to kind of tag along to that, I think what's beautiful about investing in the age that we do today is that CEOs of a lot of the biggest companies are making themselves more and more accessible to the general public. So now they're doing podcasts, long, long podcasts where you can really get a feel for this person. And depending on how public like their persona is, sometimes you can pick things up from the things that they say in the interviews when you realize, okay, there might be something deeper here. Like a billionaire who is envious of people who he considers peers who have been able to do this, this, and this in the technology, and he hasn't been able to, you know, he's just in this technology, which it's considered lower class than this technology.

32:34So maybe all of the decisions he's making is based on that envy he feels or whatever he's trying to prove. And I think those are things you can pick up from conversations and podcasts. What is that phrase when you accidentally let something slip while you're talking and it shows kind of like where your mind's at? I can't remember. Oh, like a Freudian slip? Yeah, yeah, yeah. Like you might stumble across a podcast where you hear that from a CEO and you're like, oh, that starts to explain why what I thought the company was going to do. And the reason I invested in this company is actually a different track.

33:17So to get to that place, to Dave's point, you have to be asking the question why. Because if you never ask the question why, you figure I already know the answer. You stop digging. You don't come across these other alternative reasons, the real reality. I keep saying that because I don't know what else to say, but real reality, well, duh, that situation, you won't come to that if you're not digging and asking why. Yeah, yeah, for sure. For sure. I mean, you see it everywhere. And like I said, once you see it, you can't kind of unsee it. Like if you go on social media and you see somebody really pushing hard positively or negatively about a company, for example, chances are they're either pushing it because they want the company price to go up or they want the company's price to go down and it may not always be evident but sometimes if you dig a little bit deeper into why they're pushing why they're super negative about a company it's because they're shorting the company or positive or the vice versa they're they're long the company and they're writing about it they want people to subscribe to their newsletter again not saying this is a bad thing but incentives will sometimes well, a lot of times push our behavior.

34:33And so it's good to be aware of that whenever you're trying to take in information from an authority bias, for example. So again, stacking. Yeah. And that's actually one of the things that Munger said was about these particular things. So I'm glad you keep bringing up the stacking because yeah, that's huge. Yeah. Yeah, they don't exist in a vacuum. All right. The next big one that Charlie talks about in the speech is the Lollapalooza effect. So what are your thoughts on this one? Man, this one's hard because I feel like I don't fully grasp everything he was trying to communicate with this one.

35:14The way I understand, and I think there's multiple layers to this onion, but one of the examples I remember reading in the book, which, by the way, if you haven't read Poor Charlie's Almanac, it's a pricier price point than a normal book would be. Maybe throw it on your Christmas list and maybe Santa will give it to you. In that book, he mentioned Coca-Cola and how Coca-Cola had become a Lollapalooza effect because you might think you know Coca-Cola's business. Oh, okay, they sell Diet Coke, they sell Cherry Coke, they sell whatever. Actually, Coca-Cola, the stock that Charlie and Warren bought, they actually just sell the syrup.

35:56And then other companies are the ones who will do the bottling, they'll do the distribution. They'll do a lot of the capital-intensive stuff, and Coca-Cola gets to sell at a very small price. So when you think about how much do we pay for a bottle of Coke or a bottle of Pepsi, whatever. I think we were at a hotel together a year ago, and it was like$6 for a little bottle. That's still burning my memory. That was a lot. Yeah, I was like, how much? Well, what's the cheapest? When you used to buy when you were a kid, do you remember how much a bottle of Coke would be? 50 cents. 50 cents. Yeah, 50 cents.

36:37Yeah, 50 cents. Crazy. Okay, so we're at like six bucks today. But really, the amount that Coke will charge for syrup, I don't know the exact number, but it's still probably less than a dollar. I think it's still in the pennies. I remember when he was talking about in Poor Charlie's Almanac, It was somewhere like$0.25 or$0.50 or something. It was really, really small. So there's a lot of pricing. There's a lot of price power that is still untapped that Coca-Cola could essentially tap into. They've chosen not to because they want to keep customers happy. They want to keep the ecosystem happy and all these things.

37:17So from my understanding, a lot of plays the effect being a good thing for a business and giving them the type of returns and the type of profits that is not typical with a particular business because there are certain aspects that just make it special. And in the case of Coca-Cola, it was them selling syrup at such a small unit cost, spreading that out over hundreds of millions or billions of servings, and then having that lever of, okay, a couple of cents here, a couple of cents there, billions of dollars. So that's all I remember from it. I'm probably not painting that entire picture with all the strokes and brushes I should, but that's what I remember.

38:01Please correct me on some of that. I think you're pretty right on. The way that I remember it is kind of like Seize Candy, one of the companies that they bought. I think he might have referred to that in another speech as an example of something that was kind of a Lollapalooza effect in that there were all these combining factors that go into finding a great investment. And it was a super rare event. And for C's Candy, I think it was a combination of the quality of the chocolate, the social proof that it had because of when you gave that to somebody that you love, it was a sign of caring. and then just the brand recognition or the authority that the brand had.

38:52All those things kind of combining make it a Lollapalooza effect and it's a rare breed that you can find something like that that has these qualities that make it really appealing and give it a lot of authority that really make it a great investment. I don't remember his exact phrase, but the meaning, I guess I'm going to paraphrase strongly. If you find something, oh, all a palooza effect, double down on it. Because those are rare events to find. And those are things that you should look for when you're out in the investment world, is try to find these different combinations of positive effects that lead to something being greater than the sum of its parts, I guess, is the best way of putting it.

39:41I think I do remember the Seize Candy example now that you mentioned it it was something about like and to your point combining a lot of these negative biases and emotions and turning it into a positive for the companies we're investing in but the power of incentives I remember he used the Seize Candy example you're going to buy a box of chocolates for your crush and give it to her with some flowers, are you really going to quibble over a 50 cent upcharge of the price? And I think that was an example of that. And you combine it with, like you said, the social proof and some of the other things.

40:24Yeah, that's brilliant. Yeah. Yeah. It's a rare event. And I think he and Warren have found a few of those along the way. And Charlie likes to mention this, if you find these things along the way that they're very valuable and you should definitely take advantage if you can. Nice. Yeah, that's cool. Yeah. August is National Wellness Month, but most health trends equal things like buying random gadgets and guessing at what actually works based on whatever's trendy at the time. And I wanted to stop guessing at things like that and actually look at the data behind my body. I've mentioned it before, but lately I've been taking time in the gym much more seriously, not just to build a bunch of aesthetic muscles, but to build a good, sustainable, long-term health plan for my future.

41:08Your daily resilience leaves a clear data trail in your body and function tracks the exact markers behind your energy and immunity. Not a generic overview. They look at core biomarkers like white blood cell count, which maps your frontline defense against invaders, HSCRP, which catches hidden energy draining inflammation, vitamin D and zinc, which are essential immune anchors and commonly low in a lot of people. Plus there are secondary metrics that they cross-reference, things like ferritin, which is iron levels behind your energy, MMA, which is your active B12 for energy and nerves, and cortisol, which is how stress is actually impacting your body.

It was excessive self-regard tendency. Yeah, right. Okay. So what are your thoughts on that one? This one I'm less familiar with, to be honest. Yeah. Pulling up the transcript, he basically said, we think we're better than we are. he's the example of apparently it was 90 % of Swedish drivers judge themselves to be above average maybe in Sweden they just have no car accidents I don't know but say 90 % of you are above average might be a little much and then he also then kind of like logically followed this with it applies to your major possessions he used like a spouse, children.

43:28But he also said minor possessions too. And a good example of this, which I believe had been confirmed in psychological trials and things like that, where if you... I have this blue pen in my hand. I think it's worth more than it actually is because it's my blue pen. But they do a test where they say, okay, here's the value of the blue pen, it's 50 cents. Are you going to pay for it? No, I'm not going to pay 50 cents for a blue pen. But when we own the blue pen, we think it's worth a dollar. So that's actually apparently was called in the psychology world, that's called the endowment effect. And now you can take that effect and you can apply it to yourself.

44:19They said lotteries, people irrationally enjoy the lottery numbers that they pick themselves rather than the lottery numbers that are picked at random, even though your odds are basically the same. And then he also said, uh, the foolish bettors accuracy and appraising his relative degree of talent. So making, making gamblers think they're better than they are and then even in hiring decisions I like the quote so I'm just going to repeat it employers grossly over appraise the worth of their own conclusions that they rely on impressions in face to face contact that's funny he has so many zingers in this that I don't even feel comfortable saying some of them out loud so I won't but he definitely has some really funny zingers.

45:14But we need to look at that and understand that this is part of the human condition. It's something that even if you try to not do it, you're going to do it. We're all going to feel. It's part of being human. It's part of living. We love and we enjoy and we have these things. So it's just a reminder that we need to stay humble and that even if you're not trying to not stay humble, your tendencies will be to be prideful. And so I'm going to guess, I'm going to make the intellectual leap that you need to be making consistent attempts to keep yourself humble because our natural tendency is to not be that way.

45:57Yes, yes, for sure. Yep, for sure. For me, an easy way to counteract that is if I'm thinking that maybe I'm better than I am playing a guitar, I simply have to put on a Jimi Hendrix album. So it's a very quick assertion. So something like that can be very helpful to help rein in any sort of preconceived notions that we are better than we are. and it could be the same with investing too. You can think that you're picking the greatest companies but if you look at your performance of your portfolio over a longer period of time and see that is not the case then there might be some room for improvement and so even though we get very familiar with the companies that we own sometimes we you know maybe overestimate our abilities to analyze or value a particular business and we have to be cognizant that we can be wrong and the market will humble us very, very quickly.

47:03It certainly will. You know, maybe we need to bring the Indy 500 over to Sweden and so they can see what a real driver looks like. Right. We'll have to talk to Stephen about that. He may have some connections. Yes, we will. Good idea. All right. So the last thing that we wanted to talk about that's kind of related to charlie's speech is the importance of mental models so charlie mentioned something he advocates for this idea of building lattice work of mental models so could you kind of break that down and talk to people about what that means to you yeah i mean it can be so deep really i think there's a couple ways to look at it the way i try to apply it to myself personally you can you can apply it from a general broad educational viewpoint, which he's done.

47:54But then you can also apply it on a micro level. And I try to do that when I look at companies. And it hasn't been like a perfect... I'm not making Eggo waffles here. But the idea is if I made enough different types of waffles, when I see a waffle that looks like a honeycomb, then when I see another waffle looks like a honeycomb, I can see the similarities. So for me, a good example of that was McKesson in the medical distribution business. Once I learned about McKesson and you learn about mature industry, three big players, big middlemen, I almost called it, I think I called it somewhere like a reverse hourglass where you have a ton or no, it was just like a regular hourglass.

48:48So you have a ton of suppliers, a ton of customers, and it compresses into three big players. And that's like the hourglass. So if you have that mental model, you can see that play out in other industries too. Not every industry because every industry is different, but you can start to see mental models in different industries. And so you can also apply that to competitive advantages and moats, economies of scale, scale economy shared, network effects, all of those things. You see it in one business, you can see it in another business. So if I see a network effect with American Express, I can understand how that same network effect can work at Costco.

49:24And so I'm not making Eggo Waffles because they're two different businesses, but I can recognize American Express's waffle and Costco's waffle has a lot of similarities. So when I'm trying to learn Costco's business model, if I already know American Express's, now I've just learned it that much faster. I had no idea that you were in love with Eggo Waffles so much. I kind of want one right now and I don't eat them enough so I keep myself away from too many donuts so that's actually above the list of egg and waffles but I mean yeah some egg and waffles would be good right now good to know good to know that is gonna wrap us up for this episode hopefully you enjoyed Dave had some mic difficulties we will get that fixed and we'll be good to go for next time If you have any questions, if you'd like us to answer anything on the show, even if we've answered it before, it's all good.
