munger-mental-models-worldly-wisdom

Overview

This skill distills Charlie Munger's core frameworks from Poor Charlie's Almanack: the latticework of mental models, the 10-principle investing checklist, and the 25 psychological tendencies of human misjudgment. Use it to evaluate investments, diagnose cognitive biases, or apply multidisciplinary thinking to any complex decision.

When to Use This Skill

• User wants to evaluate a stock, business, or investment using Munger's framework
• User asks about cognitive biases, psychological tendencies, or irrational behavior
• User wants to "think like Munger" or "apply worldly wisdom" to a situation
• User asks how multiple mental models combine (Lollapalooza effect)
• User wants to check their reasoning against Munger's investing principles

Core Principle

"Acquire worldly wisdom and adjust your behavior accordingly." — Build a latticework of mental models from multiple disciplines (mathematics, psychology, physics, biology, economics, history) and hang all experience on this structure. No single model suffices — you need many models working together. Invert always: collect instances of failure to find the path to success.
