About the Book

Simple equations for sharper decisions. 30 binary mental models to cut noise and choose better—fast.

What is Greater Than?

"Greater Than" is a design-forward book of 30 binary mental models (X > Y) built to help you decide faster and better. Each equation cuts through noise and gives you a clear framework: choose the left side 90% of the time, and know exactly when to flip.

Every chapter is 2–4 pages: one equation, one story, an Antithesis (when to flip), decision filters you can apply in 20 seconds, and practice prompts. Readable in one sitting. Built to be used the next morning.
