## Start from a Problem Start with **Thinking**, then move to **Models** when the problem becomes structurally complex. Start with **Effects** to see the default distortions built into human judgment. Start with **Laws** and **Principles** when you need stable constraints rather than cleverness. Start with **Methods** when the gap is execution rather than understanding. Start with **Fallacies**, then use **Paradoxes** to test where intuition may still be too shallow. Start with **Strategies**, then ground the choice in **Models** and **Philosophy**.
