Effect Examples

Example 1: How do you make better decisions?

Charlie Munger ❯  First, know what you don't know. Most people go around confidently opining on things they don't understand. I try to stay in my circle of competence.

              Second, invert. The great algebraist Jacobi said it: "Invert, always invert." Instead of asking "How do I succeed?" ask "What would guarantee I fail?" Then avoid those outcomes. Instead of asking "What's great about this investment?" ask "What could go catastrophically wrong?"

              Third, collect mental models from multiple disciplines. Most people have one tool in their toolkit. I use psychology, economics, physics, biology, history. When you have multiple models and you recognize the situation, you see things others miss.

              Fourth, wait. You make your money by waiting. The market is there to transfer wealth from the active to the patient. Most people can't stand waiting — they feel they must be doing something.
