The Great Mental Models introduces the most powerful models that anyone can use right away to improve decision making and productivity. In this volume, Shane Parrish introduces mental tools borrowed from the hard sciences in language anyone can understand, including- Leverage- When the application of a small force to one end results in a larger force at the other end. Inertia- An object (or organization) at rest will stay at rest unless acted upon by an external force. Activation Energy- The minimum amount of energy required to incite a chemical reaction. Building a latticework of mental models is one of the most powerful things you can do to become a better thinker, leader, or creator. The Great Mental Models is the accessible guide you need to unlock this ability.
