Hedgehogs and foxes

29 June 2026

"The fox knows many things, but the hedgehog knows one big thing."

- Archilochus (attributed)

One of the side effects of how media has developed over the course of the last decade is that I now get a lot of my own ideas and understanding from: a) magisterial books of popular non-fiction intended to convey big ideas or explain historical trends, and b) Substack posts, Youtube videos and Wikipedia articles. In this I hold myself to be pretty typically millennial, albeit without getting content from short-format social media. 

Our topic for the day, then, is this explainer on the concept of the hedgehog and the fox as a way of understanding expertise. One point that the author ('Youtuber' would be more correct, but no) raises is that 'hedgehog' thinkers - those who tend to have one big theory or lens of understanding, and who tend to relate everything to it - to be more confident in their explanations and predictions. They are also correct no more than chance. Foxes, on the other hand, are adaptable and draw from many domains in their thinking. They tend to be both less confident in their explanations and predictions, and more correct.

This concurs with my experience, and with my belief that a toolbox of approaches is the key to understanding and managing complex problems. The problem, of course, is that we live in a world of hedgehogs, all touting their particular 'one weird trick' to solve your problems, and all with the sort of confidence that inspires belief in the solutions that they sell. I'm not here to tell you that what I do is the One Solution for your business. But it is, I think, a valuable part of the toolkit, which bears use and integration with the other tools that cunning foxes need to survive out there. Because the problem for hedgehogs is that, one day, curling up into a ball doesn't work anymore.
