#024 – How to Break Down Complex Problems Using First Principles

Are you facing roadblocks in your projects or being stuck with outdated solutions?

First-principles thinking helps you break problems into basic truths, uncovering innovative and effective answers.

Apply first-principles thinking to tackle challenges clearly, discover fresh perspectives, and build systems designed for success.

What is First-Principles Thinking?

First-principles thinking means digging deep to find the most basic facts about a problem—facts that cannot be simplified further. From these basic truths, you can build solutions without relying on assumptions or existing methods. This makes it easier to solve problems clearly and creatively.

How to Use First-Principles Thinking

Here’s how you can apply this approach:

1. Break the Problem Down: Identify the basic facts or principles behind the problem.
2. Rebuild a Solution: Create a solution using those basic truths.

This process might sound simple, but it takes focus and effort to uncover the root principles. Here are two techniques that can help:

Techniques for First-Principles Thinking

1. The Five Whys: Keep asking “Why?” to find the root cause of a problem. This method is often used in research and can help you uncover first principles within a few iterations. You can keep going until you reach the core truth.
2. Socratic Questioning: Ask different types of questions to challenge assumptions and find the truth. Examples include:
   • Clarification: “What do you mean by this?”
   • Probing Assumptions: “What could we assume instead?”
   • Probing Evidence: “Why do you think this is true?”
   • Implications: “What effect would that have?”
   • Alternatives: “What else could we do?”
   • Questioning the Question: “Why are we asking this?”

First-Principles Thinking in Action

Elon Musk provides a great example of this. When working to lower the cost of batteries for Tesla, he didn’t accept the existing high prices as fixed. Instead, he broke the problem down to its core materials—lithium, nickel, and cobalt—and analyzed their market prices. By rethinking the manufacturing process from these basic truths, Tesla significantly reduced costs and revolutionized battery production.

Why It Matters

First-principles thinking helps you:

• Come up with fresh ideas.
• Solve problems more effectively.
• Build systems that work well in changing environments.

Conclusion

First-principles thinking is more than a way to solve problems—it’s a mindset.

By focusing on basic truths and building solutions from there, you can think, solve challenges better, and innovate in your field.
