First Principle Thinking

In life and work, we often encounter complex problems where traditional solutions or experience-based thinking are no longer effective. This is when first principle thinking can help you break down barriers and find newer, more creative solutions. This approach has been successfully utilized by Elon Musk, the founder of Tesla and SpaceX, to tackle challenges across various fields.

1. Concept

First principle thinking is an approach to problem-solving by breaking things down into their most fundamental elements and rebuilding from the ground up, unaffected by existing viewpoints or assumptions. Instead of relying on "advice" or "common assumptions" that others have provided, you explore the root of the problem and derive solutions based on the most basic principles.

This thinking differs from reasoning by analogy, where we often compare and apply solutions from similar past situations.

2. How to Practice First Principle Thinking

- Break Down the Problem: When faced with a complex issue, ask yourself, "What are the most basic elements of this problem?" Analyze them in detail and separately.

- Identify Assumptions: Examine all the assumptions you or others are relying on, and challenge them. Ask questions like, "Why is this true? Is there evidence to support it?"

- Rebuild from Scratch: After dismantling unnecessary assumptions, reconstruct the problem from its roots. Try to find solutions based on the basic elements you've identified.

- Continuous Practice: First principle thinking requires patience and ongoing practice. Try applying it in small daily situations before expanding to larger problems.

3. Illustrative Example

Suppose you want to create a new sandwich at a low cost while still ensuring great quality. Instead of following a traditional recipe, you can apply first principle thinking to analyze and optimize each component of the dish.

- Break Down the Problem:

Question: What are the fundamental elements of a sandwich?

These are: bread, filling (meat, vegetables), condiments (sauces, cheese), and preparation method (toasting, layering).

- Identify Assumptions:

+ Assumption 1: "Bread must be white or regular bread."

Question: Why not try a different type of bread, like whole grain or gluten-free? Can costs be reduced by using a different flour to make the bread?

+ Assumption 2: "The meat filling must be deli meat or chicken."

Question: Is there a way to substitute the meat filling with a different protein source like tofu or lentils that is both nutritious and cheaper?

+ Assumption 3: "Condiments must be common sauces like mayonnaise or ketchup."

Question: Can we make a sauce from natural ingredients at a lower cost that offers a unique flavor? For example, combining peanut butter with lemon and garlic to create an entirely new sauce.

- Rebuild from Scratch: After dismantling traditional assumptions, you might come up with a new idea: use homemade whole grain bread to save costs, combine it with a filling made from tofu or lentils, and use a self-made sauce from peanut butter. This not only helps you reduce costs but also creates a unique, healthy sandwich that suits a wider range of dietary preferences.

Practicing first principle thinking not only helps you solve problems more effectively but also opens doors to creativity and new approaches you may not have considered before.
