20 Mental Models from Scott Page's "The Model Thinker"
| Your Question | Model to Apply | What to Look For |
|---|---|---|
| Why do some creatives 10x? | Power Law | Top 10% driving 60%+ = home run game |
| How do winning hooks spread? | Diffusion | Pattern reuse, R₀ > 1 = viral spread |
| Optimal A/B test strategy? | Multi-Armed Bandit | Explore/exploit ratio, UCB allocation |
| Donor lifecycle states? | Markov Chain | Transition probabilities between states |
| Best ask string? | Signaling | What amounts communicate to donors |
| Why do donors lapse? | Threshold/Tipping | Fatigue accumulation until they tip |
| TLH geographic patterns? | Spatial Models | County clustering, underserved areas |
| Competitor strategy? | Game Theory | Nash equilibrium, best response |
| Are we stuck on local peak? | Rugged Landscape | Incremental vs radical innovation |
| Resource allocation? | Colonel Blotto | Which battles to concede vs win |
Is this about Prediction, Explanation, Design, Decision, or Strategy?
Ask: "What model might apply here?" Use the Quick Reference table for common scenarios. More models = more perspectives.
Each model has a "key question" it helps answer. Run your data through that lens. What do you see?
Where do models agree? = High confidence insight
Where do they disagree? = Interesting tension or tradeoff to explore
What's the composite action? = Your recommendation
Every model can serve 7 purposes:
Say any of these to invoke many-model analysis:
