Munger's Core Principles of Common Sense
So, what exactly does Munger's common sense boil down to? It's not just about being logical; it's a whole framework for thinking and acting. Here are some key principles:
1. Multidisciplinary Thinking
Munger is a huge advocate for learning from a wide range of fields. He believes that to truly understand complex problems, you need to draw insights from various disciplines like history, psychology, mathematics, and engineering. This approach, known as multidisciplinary thinking, helps you avoid tunnel vision and make more informed decisions. For example, understanding psychology can help you recognize cognitive biases that might cloud your judgment. Similarly, knowledge of history can provide valuable context and prevent you from repeating past mistakes. By integrating knowledge from diverse fields, you can develop a more comprehensive and nuanced understanding of the world. This holistic approach is crucial for effective problem-solving and strategic thinking. In practice, this means dedicating time to reading and learning about different subjects, even those that seem unrelated to your primary field of interest. It also involves actively seeking out diverse perspectives and challenging your own assumptions. Munger himself is an avid reader and learner, constantly expanding his knowledge base and applying it to his investment strategies. This commitment to lifelong learning is a hallmark of his success and a key component of his common-sense philosophy. Ultimately, multidisciplinary thinking enables you to see connections that others miss and make decisions that are both well-informed and creative.
2. Understanding Cognitive Biases
One of Munger's big things is understanding cognitive biases – those sneaky mental shortcuts that can lead to irrational decisions. He's identified a whole bunch of them, like confirmation bias (seeking out information that confirms your existing beliefs) and the availability heuristic (overestimating the importance of information that is easily available to you). By recognizing these biases, you can actively work to counter them and make more objective choices. For instance, if you know you have a tendency to be overconfident, you can seek out dissenting opinions to challenge your assumptions. Similarly, if you're aware of the anchoring bias, you can avoid being unduly influenced by initial information when making judgments. Munger emphasizes that everyone is susceptible to cognitive biases, regardless of their intelligence or experience. The key is to be aware of these biases and to develop strategies for mitigating their effects. This might involve slowing down your decision-making process, seeking out diverse perspectives, or using checklists to ensure that you've considered all relevant factors. By actively addressing cognitive biases, you can significantly improve the quality of your decisions and avoid costly mistakes. Munger's insights into cognitive biases have had a profound impact on the field of behavioral economics and have helped countless individuals make smarter choices in both their personal and professional lives. This understanding is a cornerstone of his common-sense approach to investing and decision-making.
3. Inversion
Munger often uses a technique called "inversion," which involves thinking about a problem backward. Instead of asking how to succeed, ask yourself how to fail. This can help you identify potential pitfalls and avoid them. For example, if you want to build a successful business, consider what factors might cause a business to fail. This might include things like poor management, inadequate funding, or a lack of market demand. By identifying these potential failure points, you can proactively address them and increase your chances of success. Inversion can also be useful in problem-solving. If you're struggling to find a solution to a problem, try thinking about what would make the problem worse. This can sometimes reveal new insights and lead to creative solutions. Munger believes that inversion is a powerful tool for critical thinking and decision-making. It forces you to consider different perspectives and challenge your assumptions. By thinking about problems in reverse, you can often gain a deeper understanding of the underlying dynamics and identify potential risks and opportunities that you might otherwise miss. This technique is particularly useful in complex situations where there are many interacting factors. By systematically considering the opposite of what you're trying to achieve, you can often uncover hidden vulnerabilities and develop more robust strategies. Inversion is a simple but powerful tool that can help you make better decisions in all areas of your life.
4. Circle of Competence
Stick to what you know! Munger is a big believer in operating within your "circle of competence." This means understanding your own limitations and only investing in or making decisions about things you truly understand. Don't try to be an expert in everything. Focus on developing deep knowledge in a few key areas and stay within those boundaries. This approach helps you avoid making mistakes based on ignorance or overconfidence. For instance, if you don't understand the technology industry, you probably shouldn't invest in tech stocks. Similarly, if you're not familiar with real estate, you should avoid making speculative real estate investments. Munger emphasizes that it's perfectly okay to say "I don't know." In fact, he believes that knowing what you don't know is just as important as knowing what you do know. By staying within your circle of competence, you can minimize your risk of making costly errors and increase your chances of success. This approach requires humility and self-awareness. It means acknowledging your limitations and avoiding the temptation to venture into areas where you lack expertise. Munger's circle of competence principle is a cornerstone of his investment philosophy and has helped him avoid many common pitfalls. By focusing on what he understands and avoiding what he doesn't, he has consistently generated superior returns over the long term. This principle is applicable to all areas of life, from investing to career choices to personal relationships.
5. Patience
Good things take time. Munger stresses the importance of patience, especially when it comes to investing. Don't expect to get rich quick. Instead, focus on making sound, long-term investments and letting them grow over time. Avoid the temptation to chase short-term gains or to panic sell during market downturns. Patience is a virtue that is often overlooked in today's fast-paced world, but it is essential for long-term success. Munger believes that the best investment opportunities are often those that are overlooked or undervalued by the market. These opportunities require patience and discipline to identify and to hold onto over the long term. He often cites the example of Berkshire Hathaway's investment in Coca-Cola, which was made in the late 1980s and has generated tremendous returns over the years. This investment required patience and a long-term perspective, but it has ultimately proven to be one of Berkshire Hathaway's most successful investments. Munger emphasizes that patience is not just about waiting; it's about using that time to learn and to improve your understanding of the world. By being patient and disciplined, you can avoid making rash decisions and increase your chances of achieving your long-term goals. This principle is applicable to all areas of life, from investing to career development to personal relationships. Good things take time, and patience is the key to unlocking long-term success.
