The Great Mental Models
1. The Map is a Simplification
Maps simplify complex reality to be useful
Remember what details the map intentionally leaves out
Outdated or overly simplified maps can lead you astray
2. Circle of Competence
Know the strict boundaries of your mastered skills
Unchecked ego dangerously inflates your perceived competence
Seek expert help when operating outside your circle
3. First Principles Thinking
Break problems down to their foundational, unarguable facts
Solve root causes instead of just mitigating effects
Enables highly creative, out-of-the-box solutions
4. Inversion
Turn normal problem-solving upside down
Assume success and work backward to find required conditions
Assume ultimate failure and actively avoid actions causing it
5. Thought Experiments
Simulate scenarios mentally to avoid real-world risks
Test impossible scenarios to discover new physical truths
Remove variables like money to clarify your core values
6. Second-Order Thinking
Always consider the consequences of your consequences
Prevents disastrous unintended outcomes from short-term fixes
Highlight positive long-term effects to persuade others
7. Probabilistic Thinking
Avoid extreme slippery-slope reactions by assessing actual odds
Use Bayesian updating to weigh new info against prior knowledge
Gradually update beliefs only as reliable evidence mounts
8. Occam's Razor
The simplest explanation is usually the most likely true
Explanations with fewer required variables are statistically safer bets
9. Hanlon's Razor
Attribute misbehavior to mistakes or stupidity, not malice
Intentional evil requires high energy; mistakes just require laziness
Don't take others' clumsy mistakes personally
Application
Turn theory into practice to make better decisions
Insights only have value if they change your behavior
