First Principles Thinking, also referred to as original thinking in many cases, has been driving innovation and transformation for centuries throughout history. The groundbreaking research led by Nikola Tesla, the invention of modern airplanes by the Wright Brothers and Elon Musk’s ventures in space travel and electric cars have all been fueled by First Principles Thinking. Yet, in a world where conformity and groupthink rules, how can we rewire and reframe our brains to integrate First Principles Thinking so that we can start taking steps to transform our lives, instead of just following conventional wisdom?
At the fundamental level, First Principles Thinking is all about breaking down a problem to its core truths or facts and then building solutions from there. Unlike the commonly used method of reasoning by analogy, where people compare new problems or situations with familiar and existing ones, First Principles Thinking encourages us to question age-old assumptions and recreate our understanding from scratch.
Neuroscience shows us that human brains are wired to ensure optimum efficiency. When we are faced with difficult tasks or highly complex decisions, we often depend on heuristics or mental shortcuts instead of studying and examining every detail of the problem we are dealing with. Although this tendency allows us to function smoothly in our day-to-day lives, it can also rob us of our ability to think originally. Such mental shortcuts often keep us safe and anchored to our existing knowledge, instead of challenging us to go beyond our comfort zone and explore new and radical ideas.
To cultivate First Principles Thinking, it is necessary to rewire these shortcuts and effectively engage the prefrontal cortex of the brain, the part of our brains that is associated with higher-order thinking and problem-solving. Research has proven the phenomenon of neuroplasticity, which is the brain’s ability to constantly rewire itself. This neuroplasticity is the key to developing our skills of First Principles Thinking. By regularly challenging our long-held assumptions and seeking to break down the problems, we can easily create new neural pathways that support original thought.
One of the most effective ways to build these new neural pathways is through some targeted questioning techniques. When you are facing a certain problem, you should ask yourself:
- “What do I know absolutely for sure about this problem or situation?”
- “What are the assumptions that I have about this that might be incorrect?”
- “What evidence do I have that supports or contradicts my assumptions?”
This process helps you to sharpen your critical thinking ability while allowing you to bypass automatic and shortcut-driven reasoning. Over time, by applying this technique repeatedly, you can strengthen your neural circuits that support First Principles Thinking.
Another vital aspect of developing First Principles Thinking is embracing discomfort. Human brains are wired to lean towards the familiar, so unfamiliar ideas can trigger our amygdala, leading to anxiety and even fear. By exposing ourselves to strange and unfamiliar concepts consistently, by reading widely, engaging in diverse conversations, and exploring different disciplines, we can effectively train our brains to become perfectly comfortable with the unknown. Such adaptability encourages us to develop our creativity and openness, which are essential ingredients for highly original thinking.
Furthermore, in-depth studies in cognitive flexibility demonstrate that learning new skills, like a new language, a musical instrument, or a new sport, can improve the brain’s ability to change and reconfigure the existing neural networks. This helps to develop mental agility that enables a person to easily step outside their comfort zones and biases and approach problems from completely fresh perspectives. This is why it is crucial to develop our First Principles Thinking skills.
