Spiritual Bookshelf Episode 40 : How to Build Financial Wisdom – Part 7

飛利浦 Phillip

Hi there! How’s your week going?

Today, let’s continue exploring Poor Charlie’s Almanack and dive into why Charlie Munger emphasizes learning across different fields—especially economics.

Why Study Economics?

Munger reminds us that studying economics isn’t just to become an economist. It’s about adopting a way of thinking—an analytical tool for understanding how the world works. Economics helps us interpret decisions made by individuals, companies, and even entire countries from a more rational viewpoint.

1. Understanding Scarcity and Choice

At its core, economics is about scarcity—limited resources versus unlimited wants. Learning economics helps us make smarter choices about how we spend our time, money, and energy—whether we’re picking a career, investing, or arranging our life.

2. Seeing How Markets Work

3. Sharpening Critical Thinking

4. Applying It Everywhere

Economics Is Powerful—but Not Perfect

Still, economics isn’t a catch-all. Here are some key limitations:

1. “Rational Actor” Assumption

2. Models vs. Reality

3. No Perfect Forecasting

4. Ignoring the Intangible

Munger’s Nine Flaws in Economics (Relaxed Summary)

Munger highlights issues from over-reliance on math models to ignoring real-world complexity and lacking interdisciplinary thinking. Here’s a digest:

1. The Trap of Narrow Thinking

Economics often assumes the “rational economic man,” ignoring psychology. People aren’t perfectly rational—they’re biased and emotional. Munger cites:

                  •               Loss aversion—we feel losses stronger than gains.

                  •               Herd behavior—following the crowd, even when it’s unwise.

He references Robert Cialdini’s principles like social proof, reciprocity, authority—nudges that shape our decisions. Think about Steve Jobs’ genius: people buy iPhones for emotion and identity, not just specs. Similarly, Tadashi Yanai of Uniqlo doesn’t sell luxury—he sells comfort, simplicity, and feeling “just right.”

2. Psychological Biases

Economics assumes rationality, but Munger warns of cognitive biases—confirmation bias, incentive distortions, over-optimism, etc. These explain phenomena like stock bubbles better than classic models. He praises Daniel Kahneman’s work: things like anchoring bias show how initial info affects our decisions—even when it shouldn’t.

3. Over-reliance on Math

Munger criticizes the focus on elegant math models that forget real-world chaos. For example, the Efficient Market Hypothesis (EMH) assumes markets always reflect all information—but clearly they don’t. Munger points to Li Ka-shing, who trusts intuition, context, and real sentiment over charts or formulas. During Hong Kong’s uncertainty over reunification, Li bought at low prices based on insight—not on number-crunching.

What This Means for You

In investing: Don’t assume current prices reflect everything. Look at company fundamentals, industry trends, behavioral signals like herd trends—then make decisions with a margin of safety.

At work: When chasing the hot new thing (like the metaverse), think long-term. Combine market psychology and competitor insight before jumping in—stay flexible and avoid hype.
