Understand the world, make better decisions, or at least sound smart.
Learn a new cognitive tool every week - concepts from psychology, philosophy, economics and other disciplines delivered straight to your inbox each Sunday to reshape how you see the world.
A year ago I published an article called 52 concepts to add to your cognitive toolkit, a collection of mental models that had changed my own view of the world and decision making.

Reading them all at once and hoping they stuck was a fool's errand, so I went back to the drawing board for a better solution, the result of which you see before you: Conceptually, a new cognitive tool for you to practice and incorporate into your life every week.
Why is this free?
Ideas costs nothing, but can change how we see the world. I hope this website does the same: costs me basically nothing, and can hopefully change how we all see the world.
