self-help/mental models
psychology/decision-making

Summary

American investor and vice chairman of Berkshire Hathaway — Warren Buffett's indispensable intellectual partner — whose Poor Charlie's Almanack and speeches articulate the most systematic framework for good thinking available: multidisciplinary mental models, inverting problems, and eliminating error through checklists.

Core Contribution

Developed the most practical system for general intelligence — the latticework of mental models drawn from multiple disciplines — arguing that expertise in any single field produces systematic blind spots, and that the combination of psychology, economics, mathematics, biology, and history produces a thinking advantage that compounds over time.

Key Spikes & Highlights

  • Invert, Always Invert (the Munger technique of solving problems backward — instead of asking how to succeed, ask what would cause failure and avoid it — drawn from the algebraic technique of Jacobi and applied to business, life, and decision-making)
