What is reasoning from first principles<\/a>? How can you use this kind of thinking to achieve the impossible?<\/p>\n\n\n\n

Elon Musk used reasoning from first principles<\/a> to find a new way to get to space. First-principles thinking is a way to abandon the status quo and question everything until you get to the core of the matter. You, too, can use this type of thinking to reach huge goals.<\/p>\n\n\n\n

Reasoning From First Principles<\/h2>\n\n\n\n

To achieve the impossible, we often have to abandon the status quo and find a brand new way of approaching a problem. However, according to Varol, doing this doesn\u2019t come naturally\u2014when we have knowledge of how things are <\/em>done, we inevitably begin to assume that\u2019s how things should<\/em> be done. Our knowledge of the status quo dims our creativity and makes us less likely to question the norm. (Shortform note: This is a form of the anchoring bias<\/a>, in which we unconsciously get stuck on whatever information is first presented to us<\/a>. Psychologist Daniel Kahneman<\/a> describes anchoring in detail in Thinking, Fast and Slow<\/em><\/a>.)<\/p>\n\n\n\n

Varol argues that the antidote to this tendency is reasoning from first principles. In reasoning from first principles, you throw out the status quo and question everything until you\u2019re left with only the most fundamental components. For example, if we think about education, status quo thinking would keep us focused on schools, teachers, and grades. But if we abandon the status quo and use principles-first thinking, we\u2019re left with the core of education: information to learn and a student to learn it. This opens the door for all sorts of innovative delivery methods, like online learning and self-directed learning. <\/p>\n\n\n\n

To Maximize Reasoning From First Principles, Combine It With Marginal Gains<\/strong>

Reasoning from first principles is related to the idea of marginal gains, which involves making tiny improvements to multiple components of something that, when combined, improve overall performance. Combining reasoning from first principles with marginal gains can produce powerful results (for example, the British cycling team completely overhauled their performance in just five years by following this approach<\/a>). Here\u2019s how to combine these techniques:

First, break the problem down into its component parts (or first principles). For example, the British cycling team broke down their bicycles (into seats, wheels, and so on) as well as their training schedules (into sleep, avoiding illness, muscle performance, and so on).

Then, brainstorm ways to improve each component by even 1%. For example, the coach of the cycling team researched mattresses and pillows that would improve the athletes\u2019 sleep.

Finally, implement the changes. Individually, they may not make a big difference, but when combined, the overall change can be powerful. <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

How Rocket Scientists Use Reasoning From First Principles<\/h3>\n\n\n\n

Varol cites SpaceX, Elon Musk\u2019s space exploration company, as an example of reasoning from first principles. Before founding SpaceX, Musk wanted to get into the space industry, but he couldn\u2019t afford a pre-built rocket. Musk employed reasoning from first principles by questioning his goal and realizing that what he really needed wasn\u2019t a rocket: It was a way to get to space. Instead of giving up, he figured out the cost of the raw materials needed to build a rocket and decided to build one from scratch. <\/p>\n\n\n\n

(Shortform note: Musk is the most commonly cited example of reasoning from first principles in the modern era (a quick Google search for \u201cfirst principles\u201d brings up multiple interviews<\/a> with the billionaire CEO<\/a> as top hits). Varol attributes Musk\u2019s success almost exclusively to this tactic. However, Varol doesn\u2019t mention another important factor that undoubtedly contributed to Musk\u2019s success: Until recently, he reportedly worked up to 100 hours a week<\/a>. In other words, reasoning from first principles can help you succeed, but to become one of the richest people on the planet<\/a>, you must also put in the hard work.)<\/p>\n\n\n\n

How You Can Use Reasoning From First Principles<\/h3>\n\n\n\n

Varol offers three tips to get started with reasoning from first principles:<\/p>\n\n\n\n

1) Focus on subtraction (getting rid of everything that isn\u2019t truly necessary), not addition. <\/strong>This will help you boil down to first principles. What can you take away to increase your efficiency? What are you doing right now that you could stop doing to free up resources? (Shortform note: Minimalism<\/em><\/a> <\/em>authors Joshua Fields Millburn<\/a> and Ryan Nicodemus<\/a> argue that the subtraction approach doesn\u2019t just improve your thinking: It can also help you reduce stress, discover meaning and happiness, and pursue your passions<\/a>.)<\/p>\n\n\n\n

2)<\/strong> Try \u201ckill the company\u201d exercises<\/strong> in which you imagine yourself as your own competitor and try to spot fatal flaws in your plan, company, or product. This forces you to analyze your own strengths and weaknesses more objectively and question your status quo by taking on a competitor\u2019s perspective. (Shortform note: This is a valuable exercise for any group, not just companies. For example, a city council in Texas uses a \u201cKill the Community\u201d exercise to discover problems threatening the wellbeing of people in their city<\/a>.)<\/p>\n\n\n\n

3)<\/strong> Remember Occam\u2019s razor<\/strong>: The simplest explanation\u2014the one you might find by boiling things down to first principles\u2014is usually the right one. According to Varol, that\u2019s partly because simpler systems have fewer parts that could break and cause issues. But be warned\u2014simple explanations can\u2019t always address the full complexity of an issue. (Shortform note: This is how conspiracy theories arise. People tend to ignore the full complexity of a situation, which leads them to see oversimplified patterns that don\u2019t exist<\/a>.)<\/p>\n","protected":false},"excerpt":{"rendered":"
