The 10 essential mental models, in the order that builds understanding most efficiently. Start here.
This path takes you through the ten most foundational mental models — the ones that provide the greatest leverage across the widest range of situations. Each builds on the previous one. Follow them in order.
Start here. Every mental model is itself a map — a simplification of reality. Understanding this keeps you humble about all the models that follow.
Know what you know and what you don't. This model is the foundation of intellectual honesty and good judgment.
The most powerful problem-solving tool available. Decompose any problem into its fundamental truths and rebuild from there.
The complement to forward thinking. Ask "what would guarantee failure?" and avoid those things. Often easier than chasing success directly.
Think one step further than everyone else. "And then what?" is the question that separates good decisions from popular ones.
Stop thinking in certainties. Assign probabilities to outcomes and make decisions based on expected value, not gut feeling.
The simplest explanation that fits the evidence is usually correct. A powerful filter against overthinking and conspiracy.
Don't assume malice when incompetence or accident will explain it. Transforms how you interpret other people's behaviour.
Everything is a system. Reinforcing loops amplify change; balancing loops resist it. Understanding this is the gateway to systems thinking.
The capstone. Don't just survive uncertainty — build systems that gain from it. Position yourself for upside while limiting downside.
Once you’ve internalised these ten models, you have a powerful general-purpose thinking toolkit. From here, explore by discipline — Systems Thinking, Psychology, Economics — or by use case: Making Decisions, Managing Risk, Solving Problems.
