Charlie Munger, vice chairman of Berkshire Hathaway Inc., has long maintained that the company's primary advantage does not lie in complex algorithms or elaborate forecasting models. Instead, he attributes Berkshire Hathaway's sustained success to a steadfast commitment to simplicity and sound decision-making processes. This perspective was clearly articulated during a 2019 interview when Munger discussed how the firm’s philosophy emphasizes straightforwardness over complexity.
In his remarks, Munger underscored that simplicity has never been a disadvantage for their investment approach. Instead, it has helped the firm avoid unnecessary complications. He stated that while Berkshire has made mistakes over the years, these errors were not due to the choice to keep things simple. A significant part of Berkshire’s edge, according to Munger, comes from avoiding "pompous bureaucratic systems" that can slow down decision-making and stifle agility. Instead, Berkshire has empowered talented managers with the autonomy to make swift, effective choices.
This philosophy naturally leads Berkshire Hathaway to gravitate toward businesses that are easy to understand and resilient to varied market conditions. Munger and Warren Buffett developed what they call a "circle of competence," a framework used to guide investment selections based on clear expertise and knowledge areas. Investments that fall outside this domain—those deemed too complex or opaque—are relegated to a mental "too hard" pile, effectively filtered out in favor of clearer opportunities.
Further emphasizing risk management, Munger has consistently highlighted the importance of reducing the probability of major mistakes rather than focusing solely on spectacular gains. Speaking at the Daily Journal annual meeting in 2019, he humorously reflected on his lifelong interest in studying failure and human bias. Munger joked about the value of beginning such an inquiry early, quipping, "Who is not helped by an early start in a promising activity? And what activity could be more promising than diagnosing stupidity?"
Beyond identifying potential errors, Munger cautions against what he terms "deworsification." This concept refers to the tendency to spread investments across a variety of businesses that an investor does not truly understand, thereby diluting focus and increasing risk. Recognizing the boundaries of one’s competence is a form of practical intelligence that plays a crucial role in Berkshire Hathaway's investment discipline.
The investment community has seen echoes of this school of thought among other notable figures. For example, Vanguard founder Jack Bogle championed low-cost index funds combined with a consistent, long-term approach, advocating for simplicity and patience as superior strategies compared to complicated, fee-laden alternatives. Munger's message distills to a foundational investment playbook: deeply understand a few select areas, avoid the rest, and allow time and compounding effects to drive growth.
Ultimately, Berkshire Hathaway’s strategic focus on simplicity, clarity of business understanding, and empowerment of management with operational freedom has contributed to its enduring resilience. While mistakes are inevitable, the firm’s disciplined approach limits the severity and frequency of errors, prioritizing steady, sustainable success over flashy, high-risk gambles.
