Charlie Munger, the vice chairman of Berkshire Hathaway Inc., has long emphasized the importance of understanding human irrationality, a lesson he says took root during his childhood well before his rise as a titan on Wall Street. Reflecting on his early years during the Daily Journal Corp. annual meeting in 2019, Munger revealed how his observations of the adults around him profoundly shaped his investing and life approach.
As a young boy, Munger noticed that some of the adults in his life, despite being highly capable and talented, exhibited behavior he found perplexingly irrational. This early awareness was pivotal. He recalled telling shareholders, "I could see some of the adults around me were nuts — yet they were very talented. I could see how much irrationality there was in very talented people." This realization spurred Munger's lifelong quest to discern patterns behind such behavior, which he humorously termed "diagnosing stupidity."
Munger described this journey as more than just an intellectual exercise. He saw value in developing an ability to detect errors in judgment that could undermine personal and professional success. The process started early in life and extended into his investing career, highlighting the importance of understanding the cognitive pitfalls even the most talented individuals are susceptible to.
Building on this mindset, Munger adopted a set of personal principles early on that guided his approach to both life and investing. In a separate 2019 interview with CNBC's Becky Quick, he recounted that around the age of seven, he consciously decided to avoid common destructive emotions observed in others, such as envy, resentment, and self-pity. He noted, "You don't have a lot of envy, you don't have a lot of resentment, you don't overspend your income, you stay cheerful in spite of your troubles." These rules, internalized from childhood, became essential cornerstones for maintaining rational behavior and personal well-being.
Importantly, Munger focused less on chasing extraordinary intellect or brilliance and more on preventing poor decisions. This approach is a core element of his "worldly wisdom" framework, which emphasizes the use of broad mental models, adherence to simple guiding principles, and an overarching goal of avoiding foolishness. The strategy is about steadily minimizing errors rather than seeking spectacular wins.
This philosophy also aligns closely with Warren Buffett's well-known investment counsel. Together, they have distilled their extensive experience into fundamental life and investing principles such as spending less than you earn, investing cautiously, committing to lifelong learning, and steering clear of adverse emotional states that impair judgment. Buffett has similarly stressed the importance of character and prudence, suggesting people should "write your obituary and figure out how to live up to it," highlighting the value of avoiding major mistakes rather than pursuing glory.
Billionaire hedge fund manager Ray Dalio echoes a comparable sentiment. Opening his book "Principles," Dalio candidly describes himself as a "dumb" person who succeeded by systematically learning from his mistakes and methodically studying patterns of human error. This perspective mirrors Munger's early interest and institutionalizes the concept of bias recognition and correction within an organizational context.
Collectively, these perspectives underscore a grounded, pragmatic approach that values intellectual humility and the consistent avoidance of detrimental behaviors and thinking errors over chasing rare flashes of genius or rapid success.
