Inversion
A thinking framework that flips the question: seek ways to fail first so you can avoid them before chasing success.
Disciplines
Origin Story
Mathematician Carl Gustav Jacob Jacobi was famous for saying 'invert, always invert', flip your perspective. Charlie Munger adopted this principle from mathematics to investing and decision making.
Core Principles
- 1Replace 'how to succeed?' with 'how to fail?'
- 2Focus on removing failure causes before chasing opportunities
- 3Document anti-goals so you know what to avoid
- 4Prioritize prevention actions with biggest impact
When to Use
Use when making high-impact decisions, creating risk mitigation, planning important projects, or when problems seem stuck. Inversion helps open new perspectives as a list of things to avoid.
Step-by-Step Guide
Define Goal
Write clearly what positive outcome you want to achieve.
Flip to Anti-Goal
Reverse the question: what would cause the plan to fail completely.
Gather Failure Scenarios
Create the most complete list of failure causes, negligence, weak processes, to external factors.
Select Priority Risks
Assess impact and probability of each risk, then rank from most critical.
Build Safeguards
Design prevention steps or safety fences for priority risks.
Inversion
Overview
Inversion is the art of flipping questions. Instead of asking "How do we win?", we ask "How could we lose?" By mapping what destroys plans, we can install safeguards earlier.
This approach complements optimism. Optimism drives us to seek opportunities. Inversion protects us from fatal mistakes that could negate all opportunities.
Origin Story
Carl Gustav Jacob Jacobi used inversion to solve complex mathematical problems. Charlie Munger brought that principle to business. He believed it's easier to avoid stupidity than to become super genius. Howard Marks added that lasting investors aren't because they guess winners, but because they avoid permanent losses.
Core Principles
1. Start from Anti-Goals
Determine things you definitely want to avoid. In business, for instance, losing customer trust or running out of cash. Anti-goals give red lines not to cross.
2. Focus on Blockers
After anti-goals are clear, find factors pushing toward them. Could be loose processes, rushed decisions, or poor coordination. Prioritize those with big impact and high occurrence chance.
3. Remove Causes
Create systems, checklists, or fences making those risks harder to occur. This approach is more effective than adding new features without addressing root problems.
Brief Application Steps
- Write final project or decision goal.
- Flip the sentence to opposite: "How could this fail?"
- Brainstorm failure scenarios uncensored, involving cross-functional teams.
- Assess impact and likelihood of each scenario, give simple scores.
- Design prevention actions for top three risks, then assign owners.
Case Studies
- Financial Product: Digital bank maps how credit card product fails, like fraud, payment defaults, slow service. Each risk gets specific SOPs before launch.
- Government Project: Traditional market revitalization project prepares obstacle list: vendor support, design changes, and weather. Knowing obstacles, team creates flexible schedule and intensive socialization sessions.
Practical Tips
- Always document failure scenarios with follow-ups so they can be referenced for future projects.
- Invite people outside teams to see blind spots. Uninvolved people often see missed risks.
- Combine inversion with positive planning sessions so solutions still target desired outcomes.
Inversion doesn't make us pessimistic, but realistic. By mapping what to avoid first, we give safer space for innovation.
Use Cases
Business Strategy
Assess first how a business plan fails before deciding on launch.
→A digital healthcare company prepares a failure scenario list, from data privacy to patient literacy, then creates prevention protocols.
Product Development
Prevent releasing features risking user experience damage.
→E-commerce product team runs inversion session: what makes buyers flee? Results: they install stock reminders and improve refund process.
Career Decisions
Eliminate career paths clearly harmful to future.
→A young professional writes steps that stall careers, not learning, staying in toxic environments, then builds plans to avoid them.
Public Project Risk Management
Reduce infrastructure project failure chance by mapping obstacles from start.
→Local government team maps land acquisition, material supply chain, and contractor management risks before starting road projects.
