About

Mental models are "core concepts". They unchanging fundamentals for a particular subject. Learning these concepts will give you a better comprehension of the world and help you make rational decisions.

This app is a shuffled list of 138 mental models, grouped into 9 color-coded categories.

Try to do a few each day. Spaced repetition will help you remember. If you are using a mobile you can add this page to your homescreen and use it offline.

A catalyst either kick-starts or maintains a chemical reaction, but isn't itself a reactant. The reaction may slow or stop without the addition of catalysts. Social systems, of course, take on many similar traits, and we can view catalysts in a similar light.
