Inversion

Inversion is the practice of thinking about a problem backwards. Instead of asking "How do I succeed?", ask "How could I fail?" and then avoid those things.

Charlie Munger, Warren Buffett's partner, is famous for saying: "All I want to know is where I'm going to die, so I'll never go there."

Examples

Goal setting: Instead of "How do I build a great team?", ask "What would destroy a team?" Then avoid those things.
Risk management: Instead of "How do I make this project succeed?", ask "What are all the ways this could fail?" This connects directly to building a Margin of Safety.
Vendor decision: I applied inversion to a real vendor evaluation in link not tracked — asking "what would make us regret this choice?" surfaced risks we'd missed.

Relationship to Other Models

Inversion pairs naturally with First Principles Thinking — break the problem down, then invert it. When thinking about what could go wrong, Probabilistic Thinking helps you weigh which risks are most likely. And Hanlon's Razor reminds you that many failures stem from confusion, not conspiracy.

Prompts

How does Inversion reframe the question "How do I succeed?"

"How could I fail?" — then avoid those things.

How does Inversion apply to goal setting, such as building a great team?

Instead of "How do I build a great team?", ask "What would destroy a team?" — then avoid those things.

How does Inversion complement First Principles Thinking?

Break the problem down to fundamentals, then invert it to find hidden obstacles.
