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

"… 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."
