Hey there! How’s your week been?
Welcome back to the podcast. Today, we’re diving into one of the most famous chapters from Poor Charlie’s Almanack—the one about The Psychology of Human Misjudgment.
Charlie Munger didn’t just teach investing—he taught how to think. And today we’ll look at two of his key ideas: the Wealth Effect and the Golden Goose Effect. Both reveal how our own minds can trick us—and how that impacts money, work, and life.
1.The Wealth Effect – “I feel richer, so I’ll spend more.”
The Wealth Effect happens when we feel richer—like when home prices or stock prices go up—and we start spending more, even if we haven’t actually made more money.
Think about the dot-com bubble. People saw their stocks going up, felt wealthy, and started buying cars, houses, and luxury vacations. But when the market crashed, many were left with debt—and broken dreams.
Here’s how it plays out:
•Your house was worth $800,000. Now it’s $2 million. You haven’t sold it, but you “feel” $1.2 million richer.
•Suddenly you upgrade your car, book that luxury trip, maybe even take out loans for renovations.
Munger warns: this is an illusion of wealth. It makes us:
1)Overestimate our financial safety. Rising stock or house prices aren’t the same as cash in hand.
2)Take on too much debt. People borrow more, thinking their wealth will keep growing.
3)Make bad investment choices. We assume markets only go up and start chasing risky bets.
Munger’s simple advice: “Controlling desire protects wealth better than satisfying desire.”
2.The Golden Goose Effect – Killing the Goose for the Egg
You’ve heard the fable about the goose that laid golden eggs. The farmer got greedy, killed the goose—and lost everything.
Munger uses this to describe how people, or companies, destroy long-term value for short-term gain.Example – Coca-Cola:
If Coke raised prices too high just to hit quarterly numbers, customers would lose trust. That’s killing the goose for one extra egg.
Munger also warns business leaders:
Many companies take on massive debt to boost short-term earnings, only to collapse later. Think of GE—too much financial engineering, and the “goose” nearly died.
3. Humans are NOT Rational Creatures
This is one of Munger’s core beliefs—and a pillar of behavioral economics: Humans aren’t purely rational. We’re emotional, biased, and full of shortcuts.
We like to think we make logical decisions. But in reality:
•Emotions (fear, greed, anger) drive our choices.
•Biases (herd mentality, loss aversion, sunk cost) distort our judgment.
•Our brain loves “easy mode,” so we rely on gut reactions instead of analysis.
Even Warren Buffett and Munger admit: when they look at companies, they don’t just crunch numbers. They ask, “Do we trust this leader? Will this harm our reputation? Do we truly understand this business?”
It’s a mix of numbers and judgment—because they know humans aren’t robots.
