There's a book called 80/20 running and the concept is you should do 80% of your running running slow. To me, that's a very legible concept. It's very clear and small and easy to explain.

I think his book is well packaged by having a title that condenses all of his thoughts into one little sound bite concept.

But actually you know his advice about training for running is much more complex. And you know he puts together running plans and they have a thousand types of running and it's not always 80% slow running. Sometimes it's this, sometimes it's that. It's rarely exactly 80% slow running. There's a million pieces of nuance to how he would train people to run faster but to get the concept across to write it down, he makes it more legible. He simplifies it to 80% of your running should be slow.

To me, and perhaps I'm learning only to me, that concept is very related to the concept of legibility in seeing like a state. You're taking the complicated forest with many different types of trees and you're simplifying it down to one uniform thing. That's much easier to understand and easy to track and communicate. 97 trees in this area.

The same thing can happen to concepts. They have a lot of nuance and complexity but to write them it down so that they can best be communicated, you often need to remove a lot of that.
