Elon Musk is a big believer in First Principles Thinking. Not just Musk — Jeff Bezos, Peter Thiel and Feynman too. Here's what it is, how to use it, and become better at it:

What it is: Elon Musk (@elonmusk) on First Principles Thinking: It means "boiling things down to the most fundamental truths and then reasoning up from there."

A first principle is a basic truth that cannot be broken down any further. God — this reminds me of high school chemistry when we first learnt about Atoms. But that's what they're like! The basic foundations. Here are 2 techniques to use First Principles Thinking:

1. The Five Whys This is simple. Keep asking why. Already asked why? Ask again. Continuously ask why things are the way they are. It'll help you discover the root causes of problems (hence helping you solve them). You know what — Children are great at this...

Children question everything. They keep asking why (almost to the point that it gets annoying). Their curiosity enables them to think from first principles. As we get older, we lose this child-like curiosity to keep asking why.

Quick note: You don't have to stop after 5 why's but it's usually enough to get to the fundamental truth.

2. Socratic Questioning The second technique for First Principles Thinking is Socratic Questioning. 6 types of questions you can ask to dig deeper in search of the first principle (via http://untools.co):

Lastly, here's the video of Elon talking about First Principles in 2013:

Jeff Bezos (@JeffBezos): Resist proxies. Don’t mindlessly follow processes, or unquestioningly accept survey data. That is reasoning by analogy. Go out and discover fundamental truths — focus on outcomes, and real customer feedback.

Peter Thiel (@peterthiel): True innovation comes from discovering an important, fundamental truth that few people agree with you on — a secret. First principles thinking helps you discover secrets to achieve vertical progress (0 to 1).

Richard Feynman: Do your own homework. To truly use first principles, don’t rely on experts or previous work. Approach new problems with the mindset of a novice. Truly understand the fundamental data, assumptions and reasoning yourself. Be curious.

That's it on the First Principles Thinking mental model. I love it because it's simply about being curious and inquisitive about things you're genuinely interested in. Don't shy away from asking questions.
