Inversion Exercise
Overview
Flip every assumption and see what still works. Sometimes the opposite reveals the truth.
Core principle: Inversion exposes hidden assumptions and alternative approaches.
Quick Reference
| Normal Assumption | Inverted | What It Reveals |
|---|---|---|
| Cache to reduce latency | Add latency to enable caching | Debouncing patterns |
| Pull data when needed | Push data before needed | Prefetching, eager loading |
| Handle errors when they occur | Make errors impossible | Type systems, contracts |
| Build features users want | Remove features users don't need | Simplicity > addition |
| Optimize for common case | Optimize for worst case | Resilience patterns |
| Centralize configuration | Distribute configuration | Feature flags, per-tenant config |
| Synchronous request → response | Async command → event | Event-driven architecture |
Process
- List core assumptions — What "must" be true?
- Invert each systematically — "What if the opposite were true?"
- Explore implications — What would we do differently?
- Find valid inversions — Which actually work somewhere?
Example
Problem: Users complain the app is slow
Normal approach: Make everything faster (caching, optimization, CDN)
Inverted: Make things intentionally slower in some places
- Debounce search input (add latency → enable better results, fewer DB hits)
- Rate limit requests (add friction → prevent abuse, smooth load)
- Lazy load content (delay → reduce initial load time)
Insight: Strategic slowness can improve UX and system health
Red Flags You Need This
- "There's only one way to do this"
- Forcing a solution that feels wrong
- Can't articulate why the approach is necessary
- "This is just how it's done"
- Every solution feels like fighting the problem
Remember
- Not all inversions work — test boundaries
- Valid inversions reveal context-dependence
- Sometimes the opposite is the answer
- Question every "must be" or "always" statement
