The Fundamental Distinction
- Map: Mental representation, simplified model of reality
- Territory: Actual reality, complex and infinitely detailed
- All models are wrong (incomplete), but some are useful for decisions
- Perfect maps are impossible—they’d be as complex as reality itself
Why We Need Imperfect Models
- Cognitive Necessity: Brains require simplified frameworks to function
- Decision Making: Action requires manageable models, not perfect truth
- Communication: Shared mental models enable understanding and coordination
- Utility Over Truth: Models don’t need accuracy, they need usefulness
Where People Get Trapped
- Single Model Trap: Over-relying on one framework, missing other perspectives
- Precision Trap: Demanding more accuracy than situation warrants
- Universality Trap: Assuming your models apply in all contexts
- Complexity Trap: Using complex models when simple ones work better
Model Wisdom System
Hold Models Lightly: Strong opinions, weakly held—ready to update with evidence Model Portfolio: Use multiple models for complex phenomena, avoid single-framework dependence Context Awareness: Choose appropriate model for the situation and audience Regular Updates: Abandon outdated models when they stop predicting well
Resources: Thinking, Fast and Slow by Daniel Kahneman for mental model biases. The Art of Problem Solving for multiple model thinking. Super Forecasting by Philip Tetlock for model updating practices.
