First principle vs. analog thinking

  • First principles thinking: actively questioning every assumption you think you know about a given problem or scenario  and then creating new knowledge and solutions from scratch. 
  • Reasoning by analogy: building knowledge and solving problems based on prior assumptions, beliefs and widely held ‘best practices’ approved by majority of people.

Elon Musk's 3 steps Principle Thinking

  1. Identify and define your current assumptions;
  2. Breakdown the problem into its fundamental principles;
  3. Create new solutions from scratch.

"It is important to view knowledge as sort of semantic tree

Make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.

The Two Types of Thinking

Comparison thinking: comes up with solutions based on pre-existing ideas. It is the way we normally think but it also limits the solutions to possible permutations of what already exists.

First principles thinking: starts free of preconceptions by studying the fundamentals of something and then working your way to a new thing. This helps you understand complex problems.

“Physics teaches you to reason from first principles rather than by analogy. So I said, okay, let’s look at the first principles. What is a rocket made of? Aerospace-grade aluminum alloys, plus some titanium, copper, and carbon fiber. Then I asked, what is the value of those materials on the commodity market? It turned out that the materials cost of a rocket was around two percent of the typical price.”

One Method, Different Solutions

Different solutions present themselves at different layers of abstraction. Depending on how deep and thorough is your breakdown of the situation, putting them all back together may yield different solutions.

First Principle
First Principle

Is a basic, foundational, self-evident proposition or assumption that cannot be deduced from any other proposition or assumption.

"… it's important to reason from first principles rather than by analogy. The normal way we conduct our lives is we reason by analogy. We are doing this because it's like something else that was done, or it is like what other people are doing. But with first principles, you boil things down to the most fundamental truths and then reason up from there."

A first principle

...is a foundational proposition or assumption that stands alone. We cannot deduce first principles from any other proposition or assumption.

Reasoning by first principles removes the impurity of assumptions and conventions. What remains is the essentials. 

Cutting through the dogma

If we never learn to take something apart, test the assumptions, and reconstruct it, we end up trapped in what other people tell us.

We remain trapped in the way things have always been done. When the environment changes, we just continue as if things were the same.

All Stories Are Possible — Until They Are Not

Agatha Christie's Hercule Poirot encourages everybody to tell their story.  Stories help Poirot comprehend what kind of person the victim was. And to uncover the murderer’ motive.

Storytelling is powerful to uncover insights, not just the truth. Design Thinking — a process for creative problem solving — leverages the power of stories to detect human desires and needs.

Be Relentless

Sarah Linden is the least self-aware television detective.

Her dedication to her work and stubbornness are unbeatable. She never gives up. Even though she fails in many aspects of her life — like being a mother. But, she keeps showing up and trying to do better. She tries again, fails again, and fails better.

Keeping Yourself Motivated

Determination. Do something that you have willingly chosen to do. Have a sense of autonomy and self-empowerment.

Bring on companions. Shared memories and experiences are far stronger motivating factors.

Be impatient. achieve your goals as quickly as you can.

Stay curious. Do not just dream, but see the benefits for yourself.

Avoidance. Make the most out of your time and win the final pay off.

Applying the First Principles Thinking

Identify the Problem

What is something that I want to change in my life?

Deconstruct the Problem

What are the causes of my problems? How does it affect my life?

Solve the Problem

Start creating your new framework. You could think of multiple ways to achieve your goals easily.
