How does the book explain Charlie Munger’s use of mental models?

Munger’s “latticework of mental models” involves applying principles from diverse fields (e.g., physics, history) to assess investments. The book illustrates this with examples like incentive-driven behavior and compound interest, arguing that interdisciplinary thinking reduces blind spots and improves judgment.

What psychological tendencies does the book highlight?

The book dedicates a chapter to Munger’s “Psychology of Human Misjudgment,” outlining 25 cognitive biases, including social proof, envy, and commitment consistency. Griffin contextualizes these with investing examples, showing how Munger avoids errors like anchoring on irrelevant data.

How does Munger’s approach differ from traditional value investing?
