First principle vs. analog thinking - Deepstash

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.

"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.

"Well, I do think there’s a good framework for thinking. It is physics. You know, the sort of first principles reasoning

(...) What I mean by that is, boil things down to their fundamental truths and reason up from there, as opposed to reasoning by analogy.

Through most of our life, we get through life by reasoning by analogy, which essentially means copying what other people do with slight variations."

Elon Musk

"I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy. So I said, OK, let’s look at the first principles. What is a rocket made of? Aerospace-grade aluminum alloys, plus some titanium, copper, and carbon fiber. And 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 2 percent of the typical price—which is a crazy ratio for a large mechanical product."

The CEO might re-envision the way his company tackles development, by bringing in other departments that don't normally get to participate in this work, and creating incentives for original thinking from anyone in the company.

On a personal level, you may make yourself more open to other people's perspectives and find value on discussions that you may not have previously had.
