By: Robert G. Hagstrom


Embark on a journey to explore the essence of Charlie Munger’s investment philosophy and how the power of worldly wisdom can lead to superior investment results in ‘Latticework: The New Investing’ by Robert G. Hagstrom. Discover how Munger promotes the synthesis of knowledge from multiple disciplines – physics, biology, psychology, philosophy, and literature – to create a latticework of understanding. As you progress through the book summary, uncover the concepts of equilibrium, connectionism, metaphor, evolution, and complexity, which pave the way for innovative thinking and a more comprehensive understanding of the investment world.

Charlie Munger’s Latticework of Ideas

Charlie Munger, Warren Buffet’s partner at Berkshire Hathaway, advocates for the creation of a latticework of understanding by combining concepts from different disciplines. According to Munger, investment decisions supported by a cross-disciplinary approach are more likely to be correct and lead to superior investment results. He believes that a broad, classical liberal arts education produces the best thinkers, synthesizers, and leaders in all aspects of life.

Charlie Munger is a free-spirited and original thinker in the world of investing. He believes that stock picking is a subdivision of the art of worldly wisdom. Munger emphasizes that markets and economics are not separate disciplines that can be analyzed in isolation. One should have a broad vision and recognize all disciplines’ interconnectedness to gain a more comprehensive, cross-disciplinary understanding of the whole.

Munger’s distinctive metaphor for interlocking ideas is called a latticework of models. When similar concepts from different disciplines are connected, it leads to greater comprehension of each. He claims that investment professionals today suffer because of their narrow education. The pursuit of worldly wisdom as an end in itself can be advantageous in making better investment decisions, and it can be beneficial in anything one tries.

In brief, the creation of a latticework of understanding by combining ideas from different disciplines can lead to superior investment decisions, and a broad, classical liberal arts education can produce the best leaders and thinkers in all aspects of life.

The Theory of Connectionism

Edward Thorndike’s stimulus-response theory revolutionized the way we understand learning. His experiments and conclusion with Robert Woolworth showed that learning occurs when associations are made between stimuli and responses, but it’s only applicable to situations that have similarities. This means learning is built upon the existence of commonalities, and we learn better by recognizing patterns. Thorndike’s theory inspired the current theory of connectionism, which says that learning is a trial-and-error process that physically alters the neural connections between brain cells. Intelligence, therefore, is a function of how many connections a person has learned.
This theory has recently gained popularity as the core concept behind artificial neural networks, which imitate the workings of the human brain in a computer, allowing it to learn, recognize complex patterns, classify new information, and make associations between new data. Even after formal schooling, one can search for linkages and connections between ideas in various arenas, illuminating true understanding.

The Power of Metaphors

Innovative thinking can be achieved by building a latticework of mental models through understanding the basic disciplines and using metaphors to convey meaning. John H. Holland, a Professor of Psychology and Engineering & Computer Science, suggests that worldly wisdom comes from learning big ideas across various disciplines. Metaphors are not just a way of expressing emotions but also mirror our thoughts and actions. The term “latticework” itself is a metaphor representing how we create metaphors. By understanding and using metaphors, we can expand our thinking and gain a deeper understanding of complex ideas.

Illuminating the Latticework of Knowledge

The book suggests that the key to understanding the market and economy is to expand one’s search into other disciplines and find commonalities that enhance our understanding. The book also proposes a latticework of understanding that connects various areas of knowledge, where points of light appear wherever discrete thoughts connect. By laying out an issue we wish to solve against this latticework of many disciplines, we are more likely to find a well-rounded solution. The book stresses the importance of placing society’s problems on a latticework that spreads across many academic disciplines to find long-lasting solutions. Overall, the author challenges readers to think about investing in a new way and develop a clearer understanding of how markets and economies work by broadening their search for knowledge.
