How to Train Your Brain to Think in New Ways

A mental model is an explanation of how something works. They are beliefs, worldviews or frameworks of thinking. You carry a certain kind of thinking in you to arrive at a solution to a problem.

Some examples:

• Demand and Supply: to understand the economy
• Game Theory: to understand trust and relationships
• Entropy: to understand disorder and decay

“Scientists generally agree that no theory is 100 percent correct. Thus, the real test of knowledge is not truth, but utility.”

Each individual mental model is just one view of reality. The challenges and situations we face in life cannot be entirely explained by one field or industry.

All perspectives hold some truth. None of them contain the complete truth.

“All the wisdom of the world is not to be found in one little academic department.”

Develop "liquid knowledge" that flows easily from one topic to the next.

Instead of separating knowledge into different sections, isolating it, we are better off expanding, merging and liquefying the knowledge.

You don't need to master every detail of every subject to become a world-class thinker.

If you can master the fundamentals of each discipline, then you can develop a remarkably accurate and useful picture of life.
