We're biased toward adding (features, processes, complexity) when removing (bugs, friction, unnecessary work) often provides more value with less risk. **Core Principle:** Focus on what to remove, not what to add. Subtraction is more robust than addition. ## When to Use - System simplification - Process improvement - Feature prioritization (what NOT to build) - Performance optimization - Reducing technical debt - Personal productivity - Decision-making (what to avoid) - Code review (what to delete) Decision flow: ``` Trying to improve something? → First instinct is to add? → yes → PAUSE, CONSIDER SUBTRACTION → Can you achieve the goal by removing instead? → yes → REMOVE FIRST → Is current complexity necessary? → no → SIMPLIFY VIA NEGATIVA ``` ## The Via Negativa Process ### Step 1: Identify What to Eliminate Instead of "What should we add?", ask: ``` - What's not working that we should remove? - What's causing harm we should stop? - What's unnecessary complexity we should eliminate? - What's outdated that we shou
