A systematic guide to Charlie Munger's lifetime thinking framework — a latticework of models spanning physics, biology, psychology, and economics
Charlie Munger (1924–2023), Vice Chairman of Berkshire Hathaway, and the man Buffett credits with evolving him "from a gorilla into a human being."
He wasn't just an investor — he was a cross-disciplinary thinker who drew on physics, biology, psychology, mathematics, and history.
Munger was born in Omaha, where as a young man he worked in a grocery store owned by Buffett's grandfather. After earning his degree from Harvard Law School he practiced law, before Buffett persuaded him to shift to investing. The two worked together for nearly sixty years, transforming Berkshire from a failing textile mill into an investment empire worth over $900 billion.
His core belief distilled to a single sentence: Think using the wisdom of multiple disciplines — only then can you see the real world clearly.
"I have nothing to add, except agreement."
— But he never simply agreed. He reshaped everything.
