What is First Principles Thinking and How do I Problem Solve using it?

In layman’s terms, first principles thinking is basically the practice of actively questioning every assumption you think you ‘know’ about a given problem or scenario — and then creating new knowledge and solutions from scratch. Almost like a newborn baby.

During a one on one interview with TED Curator, Chris Anderson, Elon Musk (CEO, Tesla andSpace X) reveals this missing link which he attributes to his genius level creativity and success. It’s called reasoning from “First Principles.”

Elon: "Well, I do think there’s a good framework for thinking. It is physics. You know, the sort of first principles reasoning. Generally I think there are — what I mean by that is, boil things down to their fundamental truths and reason up from there, as opposed to reasoning by analogy."

On the flip side, reasoning by analogy is building knowledge and solving problems based on prior assumptions, beliefs and widely held ‘best practices’ approved by majority of people.

Essentially, first principles thinking will help you develop a unique worldview to innovate and solve difficult problems in a way that nobody else can even fathom.

Here’s how you can quickly use this in 3 simple steps recommended by Elon Musk himself.

STEP 1: Identify and define your current assumptions

When next you’re faced with a familiar problem or challenge, simply write down your current assumptions about them.

STEP 2: Breakdown the problem into its fundamental principles.

These fundamental principles are basically the most basic truths or elements of anything. The best way to uncover these truths is to ask powerful questions that uncover these ingenious gems.

Here’s a quick example from Elon Musk during an interview with Kevin Rose on how this works.

Somebody could say, “Battery packs are really expensive and that’s just the way they will always be… Historically, it has cost $600 per kilowatt hour. It’s not going to be much better than that in the future.”

With first principles, you say, “What are the material constituents of the batteries? What is the stock market value of the material constituents?” It’s got cobalt, nickel, aluminum, carbon, some polymers for separation and a seal can. Break that down on a material basis and say, “If we bought that on the London Metal Exchange what would each of those things cost?”

It’s like $80 per kilowatt hour. So clearly you just need to think of clever ways to take those materials and combine them into the shape of a battery cell and you can have batteries that are much, much cheaper than anyone realizes.”

This is classic first principles thinking in action.

STEP 3: Create new solutions from scratch

Once you’ve identified and broken down your problems or assumptions into their most basic truths, you can begin to create new insightful solutions from scratch.
