Inversion

A mental model: instead of asking “how do I achieve X?”, ask “how would I guarantee failure?” Then avoid those things.

How It Works

Flip the problem around. If you want to become a better writer, first ask: How would I become a worse writer? Answers: don’t write, write inconsistently, write about boring things. Flip them: write, write consistently, write about things that excite you.

The less intelligent person often has more agency than the “midwit” because they arrive at simple truths without the cognitive horsepower to overcomplicate them. Inversion lets you reach the same simple truths deliberately.

Connection to High Agency

In High Agency in 30 Minutes, inversion is the escape route from the Midwit Trap — the tendency to overcomplicate simple actions. The midwit mistakes simplicity for stupidity.

The process: (1) Stop trying to be the genius, (2) Ask “what would the simple person do?”, (3) Find it via inversion, (4) Take the simple answers seriously before adding any complexity.

Munger: “Invert, Always Invert”

charlie-munger borrowed the concept from the great algebraist Jacobi and made it a cornerstone of his decision-making. His version: “All I want to know is where I’m going to die, so I’ll never go there.”

Munger applies inversion to investing: rather than trying to be brilliant, “it is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent.” Avoid the big mistakes, and the wins take care of themselves. This is circle-of-competence in action — knowing what to avoid.

Naval: Avoid Incorrect Judgments

naval-ravikant echoes Munger almost verbatim: “I don’t believe I have the ability to say what is going to work. Rather, I try to eliminate what’s not going to work.” Good judgment isn’t about being right — it’s about avoiding being wrong.
