Charlie Munger’s Investing Principles Checklist, Part 2: Independence

Charlie Munger, Warren Buffett’s long-time partner at Berkshire Hathaway, is admired for his investment acumen as well as his ability to simplify complex ideas and apply them to decision-making, investing, and life in general. Munger always took a long-term approach to investing, and was guided by a set of which he referred to as his “checklist” of mental models. He believed keeping this checklist in mind at all times can help investors avoid errors and make better financial decisions.

This week we’re looking at another one of his principles: independence, and why it’s important to have your own point of view and thought process.

Munger on risk

Munger candidly said, “Only in fairy tales are emperors told they are naked,” meaning, you need to rely on yourself and be rational! He further expands on this theory as follows:

• Objectivity and rationality required independence of thought: Munger believed that clear, rational decision-making cannot coexist with blind reliance on others. Independence forces you to test assumptions, confront uncomfortable truths, and cut through biases. In practice, this means resisting the noise of market commentators, “finfluencers,” or even peers whose incentives or knowledge may be flawed or biased. Independent thinkers focus on facts, fundamentals, and rational analysis — not the the popularity of a viewpoint.
• Remember that just because other people agree or disagree with you doesn’t make you right or wrong - the only thing that matters is the correctness of your analysis and judgement: In investing, consensus may seem like a good thing, but it can also be dangerously misleading. Just because a company is widely loved and is getting a lot of media attention doesn’t make it a good investment. Likewise, skepticism from other people about your views  doesn’t necessarily mean you’re wrong. Munger emphasised that investments must be made using evidence, logic, and sound analysis. The real measure of success is not whether people agree with you in the short term, but whether your investment thesis holds over time. Independent thinking gives you the courage and conviction to stand by well-reasoned decisions, even when the crowd may disagree.
• Mimicking the herd invites regression to the mean (merely average performance): Herd mentality rarely results in superior performance. Following trends or copying others often leads to results that are no better than average — what Munger called “regression to the mean.” Outperformance requires deviating from the crowd, but not blindly. Be contrarian, but back it with rigorous research and reasoning. Independence doesn’t mean being different for the sake of it…it means having the conviction to act differently when your analysis shows that the crowd is indeed wrong.

Why it’s important

Markets are inherently noisy, emotional, and prone to bubbles and panics. In such an environment, independent thought is an investor's best defence. Independence gives investors the strength to resist the crowd, the clarity to think objectively, and the patience to stick with reasoned analysis. Without it, you risk falling prey to delusions, crowd psychology, and misplaced confidence.
