# Inversion Thinking ## Overview Inversion thinking, championed by Charlie Munger and rooted in mathematician Carl Jacobi's principle "Invert, always invert," approaches problems by considering their opposite. Instead of asking "How do I succeed?", ask "How would I guarantee failure?" then avoid those paths. **Core Principle:** "All I want to know is where I'm going to die, so I'll never go there." — Charlie Munger ## When to Use - Planning a new project, feature, or initiative - Evaluating a decision before committing - Identifying risks that optimistic thinking obscures - Stuck on how to achieve a positive outcome - Need to challenge assumptions in a plan - Writing requirements or acceptance criteria Decision flow: ``` Have a goal? → yes → Can you list ways to achieve it? → maybe → INVERT FIRST ↘ no → Definitely invert ↘ no → Define goal, then invert ``` ## The Process ### Step 1: Define the Goal Clearly State what success looks like: ``` Goal: "Ship a reliable authentication system by Q2" Goal: "Build a high-performing engineering team" Goal: "Launch product with strong user retention" ``` ### Step 2: Invert — Ask "How Would I Fail?" List all ways to guarantee failure, ruin, or

What does the thinking-inversion skill do?
Approach problems backward by identifying paths to failure, then systematically avoiding them. Use for risk identification, planning, and avoiding obvious mistakes.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill thinking-inversion --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
