📖Charlie Munger

Incentive-Caused Bias

🌿 Intermediate★★★★★

Incentives drive behavior more powerfully than any other force — always analyze who gets paid what.

💬

Never, ever, think about something else when you should be thinking about the power of incentives.

— Psychology of Human Misjudgment，1995

🏠 Everyday Analogy

Just as children are motivated to do chores by receiving an allowance, adult behavior is also driven by interests. The compensation structure of a company's executives determines their priorities. When analyzing investments, one should first examine the management's incentive mechanisms rather than relying solely on what they say.

📖 Core Interpretation

Human behavior is driven by incentives, and the structure of incentives determines behavioral patterns. "Show me the incentives, and I will tell you the outcome."
💎 Key Insight：People respond to incentives, often unconsciously. A broker paid by commission will recommend more trades. A CEO with stock options will focus on short-term stock price. A financial advisor paid by assets under management will discourage concentrated bets. Before trusting any advice, always ask: "How is this person compensated?" Their incentives predict their behavior better than their words.

🎙️ Master's Voice

The human mind is a lot like the human egg, and the human egg has a shut-off device.
Munger observes that once we form a view, our mind closes to new information. This first-conclusion bias leads to persistent errors.
