Simple equations for sharper decisions. 30 binary mental models to cut noise and choose better—fast.
"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.
Decision fatigue is real. These frameworks give you clarity when it counts.
Choose left 90% of the time. Learn when to flip.
Decision filters, traps, and team play that ship work.
Real personal, professional, and business stories stick.
Cheat sheet + workshop kit to spread the language.
Greater Than helps anyone who makes decisions under pressure. Here's how different roles use it:
Use Simplicity > Features to cut scope, Quality > Speed to pace releases, and Long Term > Short Term for roadmap calls.
"We use Focus > Hustle in sprint planning every Monday."
Apply Clarity > Cleverness in UI decisions, Depth > Breadth in research scope, and Listening > Talking in user interviews.
"Systems > Goals helped us build a design system that scales."
Leverage Prevention > Cure for risk, Margin > Maximum for capacity, and Candor > Comfort for tough conversations.
"Consistency > Intensity is now our company value."
Build shared language with Process > Outcome for workflows, Autonomy > Control for ownership, and Reuse > Reinvent for efficiency.
"We reference equations in Slack—it's our decision shorthand."
Most decision books give you one framework or 50+ models with no nuance. Greater Than gives you 30 portable equations with built-in Antithesis—so you know when to flip the rule.

Knowing 30 equations doesn't help if you can't apply them. Mental Gym gives you daily 5-minute reps to practice one equation on real decisions.
