First principle thinking is essentially about breaking problems down to their most basic truths and building solutions from the ground up.
Instead of asking, “What’s the industry standard for this?” you ask, “What is undeniably true, and why does this problem exist in the first place?”
Using First principles thinking in UX and product design, helps to cut through the noise, innovate and avoid redesigning for the sake of it.
By focusing on the core problem, a flights website managed to implement two options to edit passenger names, which included a self-serve flow and a guidance prompt.
To apply First principles thinking in work, ask why, repeatedly, challenge every assumption and dig deeper until you uncover the root cause of the problem.
Once you’ve identified the problem, strip it back to its essentials.
Now that you understand the core problem, build a solution tailored to your users, not a “best practice” from another product.
First principles thinking doesn’t guarantee a perfect solution on the first try.
Prototype your idea, test it with users, and refine based on their feedback.
When you question assumptions and focus on the basics, you avoid wasting time and resources on overly complex solutions.
