Charlie Munger, the legendary investor and partner of Warren Buffett at Berkshire Hathaway, is famous for his use of mental models – powerful ways of thinking that help simplify complex decisions. One of the most profound mental models Munger and Buffett use is “Inversion.” In simple terms, this means approaching problems by thinking about what you want to avoid rather than just what you want to achieve.
Charlie Munger is known for saying, “I just want to know where I’m going to die, so I won’t go there.” This quote perfectly captures the essence of inversion. Instead of asking, “How do I become successful?” you ask, “What will make me fail?” By understanding what leads to failure, you can avoid the traps that others fall into.
Inversion is a way of forcing yourself to consider the opposite, the dangers, and the mistakes that could derail your goals.
"I want you to help me analyze a problem using the inversion mental model. The problem I want to solve is [describe your problem].
Instead of telling me how to achieve my goal, list the top 5–10 ways I could fail at this goal.
Then, help me create a plan to avoid these mistakes."
