name: Inversion Exercise description: Flip core assumptions to reveal hidden constraints and alternative approaches - "what if the opposite were true?" when_to_use: when stuck on unquestioned assumptions or feeling forced into "the only way" to do something version: 1.1.0

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 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

Process

1. List core assumptions - What "must" be true?
2. Invert each systematically - "What if opposite were true?"
3. Explore implications - What would we do differently?
4. Find valid inversions - Which actually work somewhere?

Example

Problem: Users complain app is slow

Normal approach: Make everything faster (caching, optimization, CDN)

Inverted: Make things intentionally slower in some places

• Debounce search (add latency → enable better results)
• Rate limit requests (add friction → prevent abuse)
• Lazy load content (delay → reduce initial load)

Insight: Strategic slowness can improve UX

Red Flags You Need This

• "There's only one way to do this"
• Forcing solution that feels wrong
• Can't articulate why approach is necessary
• "This is just how it's done"

Remember

• Not all inversions work (test boundaries)
• Valid inversions reveal context-dependence
• Sometimes opposite is the answer
• Question "must be" statements
