First Principles Thinking

First-principles thinking is the most effective framework for true learning. For a long time, I found myself passively absorbing what teachers and professors told me. I wasn't taking things apart, identifying and testing their underlying assumptions, or reconstructing them from scratch. But breaking concepts down to their core truths and rebuilding them is the exact definition of first-principles thinking—and it is the only way to truly learn. Without it, we become trapped by conventional wisdom, memorizing knowledge without ever deeply understanding it.

Everything that is not a law of nature is just a shared belief. Money, border, country, and bitcoin are all shared beliefs. If we want to identify the principles in a situation to cut through the dogma and the shared belief, there are two techniques we can use: Socratic questioning and the five whys.

Socratic questioning is a disciplined, systematic interrogation process used to establish objective truths, uncover hidden assumptions, and separate genuine knowledge from mere ignorance. It generally follows a six-step process:

• Clarify Your Thinking (The Claim)

  • The Goal: Define & Explain the origins of your ideas.

  • The Questions: Why do I think this? What exactly do I think?

• Challenge Assumptions (The Foundation)

  • The Goal: Test the foundations of your beliefs.

  • The Questions: How do I know this is true? What if the exact opposite were true?

• Demand Evidence (The Bedrock)

  • The Goal: Ground your thoughts in data.

  • The Questions: How can I back this up? What are the sources?

• Consider Alternative Perspectives (Other Claims)

  • The Goal: Eliminate blind spots. A reality check for your initial thinking. It ensures you haven't built a perfectly logical argument that only works inside a bubble of your own making.

  • The Questions: What might others think? How do I know I am correct?

• Examine Consequences and Implications

  • The Goal: Understand the stakes.

  • The Questions: What if I am wrong? What are the consequences if I am?

• Question the Original Question

  • The Goal: Reflect on the meta-process.

  • The Questions: Why did I think that? Was I correct? What conclusions can I draw from this entire reasoning process?

The Five Whys is a method rooted in children's behavior. Children instinctively think in first principles. They repeatedly ask why. The goal of Five Whys is to land on a What or How. It is not about introspection, such as why do I feel like this? Rather, it's about systematically delving deeper into a statement or concept to separate reliable knowledge from assumptions. If your whys result in a statement of a falsifiable fact, you have hit a first principle. Falsifiable doesn't mean false; it means testable.

Reasoning from first principles allows us to step outside of history and conventional wisdom and see what is possible. We are all born rather creative, but during our formative years, it can be beaten out of us by busy parents and teachers. As adults, we rely on convention and what we are told because that's easier than breaking things down into first principles and thinking for ourselves. Thinking through first principles is a way of taking off the blinders. Most things suddenly seem more possible.
