The Mental Models Daily Workbook

How it works

Better decisions, one model at a time.

Mental models are the shortcuts clear thinkers use to see what is really going on. This workbook takes 60 of the most useful, from Second-Order Thinking and Inversion to Hanlon’s Razor and Bayes’ Theorem, and turns each one into a tool you can use on your own life today.

Each model gets two pages. On the left you learn it: the idea in one line, a plain explanation, the moments to reach for it and a story where it mattered. On the right you practise it: one question to ask, three short exercises to write out and a sentence to finish before you move on.
