How charlie Munger solved problems.
When Munger said, “Invert, always invert,” he emphasized a mental model rooted in reversing your perspective. Instead of just asking, “How do I solve this problem?” you ask, “What should I avoid to make sure I don’t fail?”
By looking at the problem backward, you’re more likely to uncover blind spots, mitigate risks, and will often arrive at better solutions.
Inversion forces you to focus on the obstacles and pitfalls that might not be obvious when you’re only thinking in a forward direction. It can be an incredibly useful way to clarify your thinking, avoid mistakes, and simplify complex problems.
Why Inversion Works
Munger used inversion because the human brain is wired to think forward, often with overconfidence or a narrow focus. But when you invert, you force yourself to confront uncomfortable truths and anticipate what could go wrong. It’s a way of “debugging” your thought process.
For example:
- Instead of asking, “How can I be happy?” ask, “What things make people miserable, and how can I avoid those?”
- Instead of asking, “How do I build a successful business?” ask, “What are the common reasons businesses fail, and how can I avoid them?”
By flipping the problem, you reduce errors and make success more likely.
Inversion is a tool for clarity and simplicity. By focusing on what to avoid, you often eliminate unnecessary complexities and distractions. It can be applied to everything, business decisions, investments, life goals and problem solving.
