I want to begin with a scene that I believe you have experienced. Around 11 p.m., the room was quiet. You 're scrolling through your phone and suddenly an item pops up that's on sale. Only a few left, and suddenly a very persuasive voice pops into your head. I deserve it. Things have been tough lately.
Thousands clicked to buy. The next morning, you look back at the order confirmation message and that familiar feeling comes back. What am I going to buy this for ? That moment doesn't just happen with objects; it happens when you send a text message while you're angry. When you submit your resignation right after a bad meeting .
When we trust someone simply because they're so captivating to talk to, and it happens again and again, we tell ourselves we'll be wiser next time. But then the next time we did exactly the same thing . At this point, I think there's a question worth pausing to answer. If these mistakes stem from a lack of understanding, then further learning will solve the problem.
But did you notice? Those who frequently fall into these traps are often not unintelligent. They are hardworking, they are qualified, and they are good at their jobs. Yet, at the most crucial moments, that brilliant brain seems to shut down. That's the paradox I want to explore with you today. Why do intelligent people often make the wrong decisions?
And in response, I'd like to invite you to meet someone. His name is Charley Moner. If you know Warren Buffett, then Moner is the person who stood by him for over 60 years, serving as vice president of Bai Hawe. But what attracted me to him was n't his wealth, but his perspective on life. That's a very strange perspective at first glance.
He once said something along the lines of, "All I want to know is where I'm going to die so I never get there." Sounds like a joke, right? But think about it, most of us spend our whole lives asking how to succeed. Now, let me ask you the complete opposite question: how to avoid failure? And perhaps that very reversal is the whole secret.
He once emphasized that his greatest advantage in life didn't come from trying to be extremely intelligent, but from consistently avoiding doing stupid things. It sounds humble, but when you delve deep enough, you'll see just how difficult and powerful it is. In the next 30 minutes, I won't be giving you a magic recipe.
I will do something different with you, exploring how time perceives the world, the subtle psychological traps that control our decisions, and the small habits that can change the way you live. And to keep this article honest, I will also discuss the limitations in his own thinking. Because a truly independent thinker will not trust anyone, not even blindly.
Let's start where he began. Part one: Avoid mistakes instead of finding the secret. There's a saying that Mon really likes to repeat, and he borrowed it from the German mathematician: reverse, always reverse. Jobi said this when talking about mathematics. When a problem is too difficult, don't try to solve it easily.
Try looking at it from the opposite perspective. Mun has now taken that idea and applied it to her entire life. Let's see how it works. Let's say you want to have a happy life. The common question is, how can one be happy? And this is where things become ambiguous. You will encounter thousands of contradictory pieces of advice .
Slow down, be more ambitious, let go, and persevere. You don't know which one to believe. Now let's reverse it. Instead of asking how to be happy, ask what will definitely make me miserable. Suddenly the answer became much clearer . Envy, resentment, self-pity , breaking promises, learning only from one's own experiences and never learning from the mistakes of others.
Giving up after the first failure—we all know where that leads, and we realize it much faster than defining what happiness is . Muon Gio once presented a list like this in a graduation speech. as a recipe for a miserable life. He told the young people, both humorously and seriously, that if they wanted to avoid that outcome, they just needed to do the opposite.
Why is this method effective? I think there are two reasons. First, our brains are attracted to flashy things. When we want to succeed, we look for new strategies, new opportunities, and new secrets. But we almost never stop to ask what is silently dragging us down. In reality, what ruins a life is rarely the lack of a clever strategy, but often a major mistake or a series of small mistakes repeated over and over again .
Secondly, avoiding the bad is easier to identify than identifying the perfect. No one can be certain what the perfect job is . But most of us know that a job that exhausts you and doesn't teach you anything should be avoided. Try applying this to three specific areas. When it comes to finances, don't ask how to get rich quick, but ask what will definitely make me lose all my money.
The common answer is to borrow money to invest in something you don't understand, put all your money in one place, and follow the crowd. When it comes to career advancement, don't just ask how to get ahead, but ask what will definitely make me worthless in 10 years . Perhaps it's about stopping learning, working with dishonest people, or relying on a single supervisor or skill .
In relationships, don't ask how to be liked, but ask what will definitely ruin the relationship. Prolonged silence, small but frequent acts of disrespect, and broken promises . Do you see? A list of things to avoid is always more specific than a simple "Keep trying" slogan. But now there's a further question I'd like you to consider.
If avoiding such obvious mistakes is possible, why do we still make them? Because we don't make these mistakes by chance. We fall into very specific patterns, and we almost never realize it. M spent years researching this, and in 1995 he gave a famous lecture titled "The Psychology of Human Misjudgment," listing dozens of psychological tendencies that cause intelligent people to act foolishly.
I won't go through them all. I've selected six traps that I think you encounter almost every week. Trap one: Confirmation bias. We are not searching for the truth. We look for things that prove the curtain is right. When you believe a stock will rise, you'll carefully read all the articles supporting it and quickly skim over any warnings.
Once you have a bad impression of a colleague, you will remember all their small mistakes and forget the times they did well. The sign that you are very convinced and have never heard any opposing opinions. The proactive way to avoid this is to find an intelligent person who disagrees with you and ask them where they see flaws in the plan .
72. The herd effect. When we're unsure, we look around to see what others are doing and then follow suit. That's a very ancient survival instinct . But in the modern world, it makes us buy stocks because everyone is talking about them or follow a trend simply out of fear of being left behind. The most obvious sign that you should do something is that everyone else is doing it.
Ways to prevent it. Ask yourself: if no one knew I was doing this, would I still want to do it? The triple commitment trap: consistency and consistency. This is the most cruel trap I've ever seen. Once we 've declared something or invested effort into something, it's very difficult to turn back, even when evidence shows we're wrong.
Someone stays in a bad job because they 've been there for 5 years. An investor holds onto a declining stock because they've already lost too much money . Selling now would be a waste. Each time , what we are protecting is not our own self-interest, but a sense of consistency with ourselves. The sign that you've come this far is that you must keep going.
To avoid this, ask yourself: if I were to start from scratch today, would I choose this path? Trap four. Repulsed by loss. The pain of losing something is often greater than the joy of receiving something equivalent. Muon Gio calls one form of this phenomenon an overreaction to being deprived of something one possesses.
The consequence is that we cling to things that are no longer valuable, from unhealthy relationships to failed investments. We are so afraid of losing it that we don't dare to exchange it. Signs that you can't let go of something even though you know holding on to it will only cause more harm. Ways to prevent it.
Ask yourself if something doesn't already belong to you, would you spend the money or time to get it? Seven years of meditative insight and encouragement. This is a phrase Mun often repeats now. Show me the incentive mechanism, and I will show you the results. People act based on what they are rewarded for, far more than they say.
A sales consultant who earns commission will tend to recommend you buy. A person with a vested interest in a decision will unconsciously distort their advice , even if it is entirely in good faith. Signs that someone is giving you advice that you would benefit from following. Before accepting advice, a good way to avoid problems is to ask the person what they would gain or lose from their decision.
76. Overconfidence. Finally, and perhaps most dangerously, we often overestimate our abilities . Most people believe they are better than average drivers. One thing that, statistically speaking, cannot be true for everyone. Overconfidence doesn't manifest when we feel insecure. It appeared right when we had just won and thought we had grasped the pattern.
The telltale sign is that you feel confident but have never actually recorded a prediction to verify it. The way to avoid this is to write down your predictions and reasons before knowing the results and then compare them later. Here, you might notice something interesting. These six traps are not six different diseases.
They all share a common origin, with emotions and instincts overwhelming reason at the very moment we need reason most. And this is why reverse thinking is so powerful. It forces us to confront the question of where we are most likely to make mistakes. Then those six traps were the answer. But knowing where the traps are is only half the story.
A person might be aware of all the pitfalls yet still view the world too narrowly or confidently venture into areas they don't understand. So, Subject R doesn't stop here. He also suggested two more things: a broader perspective and a clear understanding of one's own limitations . That's the content of the next section.
Part two: Seeing the big picture and knowing your limits. There's a saying I think you've heard somewhere about people who wield hammers. Everything looks like a nail. It sounds funny, but try looking around. A finance professional will view every issue through the numbers. An engineer will find technical solutions to problems that involve human factors.
A marketing student might think that everything just needs to be told better. Everyone is using the tool they're best at, and everyone thinks it's the right thing to do. The problem isn't that the tool is wrong. The problem is that we only see the part of the world that our tools can illuminate, and are completely blind to the rest.
Many call escaping this trap building a network of thought patterns . He essentially said that you can't truly understand the world if you only have a few models in your head, because then you'll be forcing reality to fit your model instead of the other way around. The solution is to borrow core ideas from multiple fields— psychology, probability, economics, history, and mathematics—and use them simultaneously.
This isn't about becoming a scholar. He doesn't expect you to become an expert in every field. He simply wants you to grasp the biggest, most important ideas in each field because these ideas bear much of the weight of explaining the world. So what does such a network consist of? I've selected four models that I think everyone should own.
The first model is probability. Most of our decisions don't have certain answers; they're just a gamble with varying odds. Instead of asking if this will succeed, ask what the realistic chances of success are and what I will lose if it fails? A good decision can still lead to a bad outcome, and a bad decision can sometimes luckily lead to a good outcome.
A person who is mentally mature is someone who can separate these two things. The second model is opportunity cost. Every penny, every hour you spend on this is a penny; an hour cannot be used for anything else. The right question isn't just whether this is good, but whether this is better than my next best option.
The third model, the margin of safety. This is a familiar idea in investing, but it's applicable for a lifetime. Always leave some room for unforeseen circumstances. The bridge builders did not design the bridge to withstand its maximum load capacity, but rather many times that. You should also avoid making such tight financial or time plans that a small incident can ruin everything.
The fourth model, the second-order effect. Most people stop at the question of what happens next. The more thoughtful person asks further questions, and then what happens next ? A high-interest loan can help you solve an urgent problem today. But the second-order effect is a burden that lasts for many years.
To see these models working together, try a specific case. Let's say you're considering quitting a stable job to start your own business. You are very excited. Instead of making a decision based on emotion, go through each model. In terms of probability, what is the actual percentage of small businesses that survive for many years ?
What is the worst-case scenario? And can you handle it? In terms of opportunity cost, what could you learn if you stayed ? How much can we save in the next two years? That's the real price of leaving. Regarding the margin of safety, how many months can you live on if your revenue is zero? If the answer is 3 months and the plan requires 12, that's a sign to stop.
Regarding the second-order effect, how does failure affect your family and relationships ? If you succeed, how will your life change? And remember part two, after going through these patterns, let's revisit the traps. Are you excited because this plan is good, or because everyone around you is starting a business?
You are being guided by confirmation bias when you only read success stories. That is the power of a network. Each model catches a type of error that other models miss. But I have to tell you one thing: having more models doesn't mean you understand everything. And this is where we move on to the second idea, one that I think is more modest and also more challenging.
Draw a circle. Inside are the things you truly understand, your profession . the field you have worked hard in. The outside is all the rest. This is the circle of competence, a concept that both Buffet and Mun mention a lot. It's worth noting that Muner and Buffet didn't say the circle had to be large.
They said something more important. You need to know exactly where its boundaries are located. A person with a small circle but who knows their boundaries is much safer than someone with a large circle. but they didn't realize they were standing on the edge. So why is recognizing boundaries so difficult?
There's a psychological phenomenon you may have heard of, the Daning Cruiser effect. Simply put, people who know little about a field are often the ones who rate their abilities highest in that field, because they lack the knowledge to recognize their shortcomings. The deeper we learn, the more we realize how much we still don't know.
This explains why people who excel in one field often fail miserably when they switch to another. A good doctor thought that his expertise could translate into investment. A successful businessman in one industry thinks he can do the same in a completely unfamiliar industry. Success in one area can make us forget that area has boundaries, and the biggest barrier to acknowledging those boundaries, I think, is self-esteem.
We are afraid to say the three words "I don't know." We're afraid of being seen as incompetent, so we say things we're not sure about and then make decisions based on things we don't understand. But let's look at it from a different perspective. Saying I don't know isn't a sign of weakness. That's a sign of someone who understands the rules of the game and knows they shouldn't enter a game they don't understand.
Buffê once said that success doesn't require you to be good at everything, but simply to recognize where you're good and stay there. So how can we expand the circle safely? The only way is through words, and with a purpose. Learn about a new field on a small scale before betting big. Ask people who actually have experience.
Make it a habit to distinguish between "I think I know" and " I have verified that I know." And accept the fact that most of the time the best decision is to do nothing when it's outside your comfort zone . We've now covered three reversal tools to understand what to avoid. A network of models to gain perspective and a circle of capability to know where you're stopping .
But all of this is still just thought. The most important question is how to make it a habit in a busy life. Part three, from principle to habit. There's a slightly uncomfortable truth I want to confess to you before we continue. Knowing something and living by it are two completely different things.
You might watch this video, nod in agreement, or even take careful notes. And tomorrow night at 11 p.m., when a discounted item appears on the screen, everything you just heard will vanish. It's not because you're incompetent, but because reason is only strong when we are calm. Bad decisions, on the other hand, often happen when we're not calm.
Therefore, instead of relying on sheer willpower and the hottest moment, erect barriers in advance. I've chosen four simple fences that are powerful enough to change the way you live. The fence has a 24-hour rule. Let me clarify that this is an application of the spirit of the subject , not a quote from him.
The law is very simple when it comes to decisions driven by emotion. Please wait 24 hours. I wanted to buy an expensive item because I was tempted by a sale. Wait 24 hours. If you want to send a message while you're angry, write it down but don't send it. Want to quit immediately after a terrible meeting?
Wait 24 hours. Why does this work? Because strong emotions are like a wave. It rises to its peak and then recedes. But a decision made at the crest of the wave stays in mind long after the wave has passed. Just give the wave a day to recede, and you'll filter out most of the decisions you'll regret later .
And there's a subtle point: if an urge remains after 24 hours, it's more likely not an impulse. It's what you really want. Barrier two: A checklist before a big decision. The world's best pilots still use checklists before every flight. It's not because they've forgotten how to fly, but because they understand that even the most skilled humans have tiring days and moments of carelessness.
Mon now strongly believes in this spirit. You should also have a separate list for major decisions, money, career, and relationships. I suggest five questions, each stemming from an idea you just heard. Reversing anything would certainly cause this decision to fail. The circle of competence—do I really understand this, or am I just assuming Minh understands it?
Tell the person advising me what they will gain from this decision. Knowing that it would be safe if things went wrong, would I be able to handle it? Emotions: If I make a decision today, am I calm or swept away? Five questions, less than five minutes, but it could be the difference between a wise choice and years of regret.
The three-journal decision barrier: This is the barrier I think fewest use, but also the most powerful. Do you remember the overconfidence trap? One of the reasons we never get better is because our memory rewrites the past. When a decision succeeds, remember that you always knew it would succeed. When failure occurs, remember that it was something nobody anticipated.
We edit history ourselves so that we always appear to be wise. The only way to break this loop is to record the result before knowing it. Whenever you have to make an important decision , write down three lines explaining what you have decided. For what reasons? What results do I expect, and how confident am I ?
Open it and read it six months later. You'll be surprised. Sometimes you think you're right, but for the wrong reason, it means you're lucky. Sometimes you find yourself making the same mistake over and over again, and that's when you truly begin to learn from yourself, not from the polished version you have in your memory.
The four-way barrier requires proactive patience. The final barrier isn't a rule, it 's an attitude. We live in a world where action is considered virtue. Those who are busy are valuable people. Anyone who sits still is lazy. And so we constantly do something, anything, just to feel like we're moving forward.
But Mun lives by a different logic. He was known for reading almost incessantly, to the point that those who knew him said he looked like a walking book . And he and his colleagues have repeatedly stated that much of their investment success comes from patiently waiting for truly good opportunities and then acting decisively when they arise, rather than trading constantly.
I call it proactive patience, to distinguish it from passive patience. A passive person sits and waits for luck. Patient people proactively wait, but while waiting, they read, learn, observe, and prepare. When opportunities arise, they are knowledgeable enough to recognize them and calm enough not to miss them.
You don't need to read all day like a bookworm. Start with 30 minutes each day. Sit still, turn off notifications, read something meaningful, and think about it. Initially, you might find it uncomfortable because the feeling of doing nothing is very itchy. But that 's a sign you're working out a muscle group that most people have overlooked.
These four fences have one thing in common. They don't require you to become smarter. They simply require you to create a buffer zone between emotion and action. And within that small patch of forest, sometimes an entire life is saved from decisions we would later regret. But if I were to stop here and let you leave feeling that Muner has found the truth, I would have fallen into the very trap that this entire article is warning about.
Because a truly independent thinker will ask another question, "Is there anything wrong with this way of thinking, or does it not suit me?" The final section will address that question. Part four: Review and Conclusion. Now let's do what I promised from the beginning—that the subject of touching is the real thing.
Not to belittle him, but because a way of thinking is only trustworthy when it can withstand the toughest questions. I would like to point out four limitations. Limit one, the risk of paralysis due to analysis. If you go through the reverse, the modeling network , the circle of competence, the checklist, the decision log, and then wait another 24 hours, you might never do anything at all.
This is a subtle trap, avoiding the mistake of forgetting that inaction is also a decision and has its price. Those who never start a business, never say "I love you," and never try anything new are also missing out on a lot. It's just that the sense of loss is quieter now . Therefore, let's distinguish between two types of decisions.
For irreversible decisions like investing all your money in one thing, quitting a job, or ending a relationship, slow down and use all the necessary safeguards. With easily reversible decisions and low risk, act quickly, try and fix. Don't use one heavy hammer for every nail; that 's the trap we talked about in part three.
Limit the two survivor biases. We heed Mon R's advice because he was a great success. But how many people are just as patient, just as cautious, and just as avid readers, yet don't become billionaires, and therefore no one tells their story? Success in this sport certainly comes from talent, but also from luck, timing, relationships, and finding the right buffet.
When we only look at the winners, it's easy to conclude that their methods are the sole cause. A thoughtful person would say this method is reasonable and helpful, but not guaranteed. Limits encompass various circumstances. Mon offers advice from the perspective of someone with immense wealth. For that person, sitting idly by and waiting for opportunities is a luxury they can afford.
For someone struggling with rent, tuition, and family responsibilities, waiting could mean missing out on a unique opportunity. This doesn't invalidate his principles , but it reminds us to adapt them to our own circumstances. The margin of safety for someone with limited resources is not the same as the margin of safety for a billionaire.
And sometimes, those who have less to lose have to accept more risks. Simply because they had no other choice. The four-person limit isn't always accurate. Even humans have opinions that are met with opposition from many people. For example, he once expressed very skeptical views on cryptocurrencies, and while many agreed, it remains a debatable viewpoint, not an absolute truth.
The best way to learn from him is to learn how he thinks, not to copy down every single one of his conclusions. These four limitations lead to a different perspective on today's entire discussion. The philosophy of touch is not a set of rules to follow. It's a toolkit for better thinking. And the user of the tool must have the judgment to know when to use it and when to put it down.
Let's look back at our journey . We begin with a paradox. Even intelligent people can make wrong decisions. And we now see why. It's not a lack of intelligence, but rather that emotions and psychological traps often override reason at the most crucial moments. The novel takes a counterintuitive approach instead of striving for the extraordinary.
Be steadfast in avoiding foolish things. Use reverse thinking to figure out what you need to avoid. Build a network of thinking models to view things from multiple perspectives. Maintain your circle of competence and dare to say "I don't know." Then, turn it all into a 24-hour waiting routine, using checklists, keeping a decision journal, and being patiently proactive.
You might find all of this sounds too simple, and it really is simple. But as Monr and BF often remind us, simplicity doesn't mean ease; the difficulty lies in doing it correctly year after year . Especially when your emotions are screaming at you to do the opposite. Therefore, I don't want you to leave with 10 things to remember.
I just want you to do one thing in the next 7 days. Choose a decision you are considering, write three lines in your decision journal, and then leave it for about 24 hours. Just make one decision and then observe what changes. Because adhering to even the smallest, right principles is the greatest leverage in a person's life.
Before I conclude, I'd like to leave you with a question, and I'd really like to read your answer in the comments. What decision do you regret the most from the past year? If you could go back, which of the six traps you encountered today do you think led you there, and would a 24-hour stretch of forest have changed anything?
