The world is complex and interconnected, and we need to understand the big ideas from big disciplines, in order to have a whole map of the reality to be able to make better decisions.

Critical thinking has to be based on going to the fundamental ideas, to the mental models. 

Mental models are the most important ideas of each science: philosophy, mathematics, physics, statistics, engineering, chemistry, biology, psychology, economics and history.

You need to know and connect them.

It is the way of thinking of the greatest in history.

The first rule is that you can't really know anything if you just remember isolated facts and try and bang 'em back. If the facts don't hang together on a latticework of theory, you don't have them in a usable form.

Charlie Munger

I basically load my head of full of mental models.

Naval Ravikant

Don’t just follow the trend. You may have heard me say that it’s good to think in terms of the physics approach of first principles. Which is, rather than reasoning by analogy, you boil things down to the most fundamental truths you can imagine and you reason up from there.

Elon Musk

The things best to know are first principles and causes, but these things are perhaps the most difficult for men to grasp, for they are farthest removed from the senses.


If our small minds, for some convenience, divide this universe, into parts—physics, biology, geology, astronomy, psychology, and so on—remember that nature does not know it!

Richard Feynman

Specialization is for insects.

Robert A. Heinlein

The book explains 100 mental models to make better decisions and think critically.

These models do not tell you what you think, rather they teach you how to think, and encourage you to think critically. 

Here are some examples of how mental models will improve your life:

Do you want to create a successful business? 

Leverage, Niches and Scale models will guide you.

• Do you want to be happy, achieve more and suffer less? 

Stoicism, Anti-fragility and Resilience give you the vision and strength you need.

• Do you want to know why you shouldn't believe what you see on Instagram? 

Plato's Cave metaphor will give you the answer. 

Do you want to boost your professional career? 

Take a look at the Incentives mental model.

• Do you want to make rational decisions? 

The 25 biases that Charlie Munger details in Psychology of Human Misjudgment will help you.
