The Book · Coming 2027
The average person doesn't exist. Every system built for them fails the rest of us.
The Real Price of Designing for Everyone
For two hundred years, we built schools, hospitals, algorithms, and cities around a statistical fiction: the average person. AI was supposed to change that. Instead, it standardized faster than anything before it.
This book asks why, and what it costs.
The measurements the book is built on
The book is the argument. These are the numbers behind it, published in full, with the data and the code and the experiments that did not work.
Single Human-AI Fit
Does a language model treat a person worse when one detail about them changes and everything else stays byte-identical?
The Average-Fit Loss
What does it cost to serve a whole population with one design tuned to its centre?
The argument, in shorter form
Pieces that work through one part of the book at a time, written for the people who own the systems it describes.
