What you will find
Michon, Crépieux-Jamin, Klages and Pulver: how graphology was born and why the human eye, however well trained, has a limit.
From an Excel sheet to millions of pixels: the day we first measured what we had only sensed, and the birth of percentiles.
More than two hundred indicators, stroke pressure, detecting AI-made handwriting and what the data say, including what did not work.
A game before we start
What percentage of this page do you think is covered in ink?
I asked this in an open class with about a hundred graphologists signed up. Answers ranged from 6 to 70 %, and no two were the same. The real answer, and what it means, is in the book's introduction.

Contents
About 37,000 words and 46 figures with real, anonymized handwriting samples, like a botany book.
The author
Psychologist and graphologist. He has taught graphology since 2002, and more than nine thousand students have taken his courses. He directs the Instituto de Ciencias del Grafismo Grafos (Chile) and created GrafoMetrics, a computer-vision platform for handwriting analysis incubated at Start-Up Chile.
A promise of method
This book will not tell you that a sign in a letter reveals who you are. It will show you what can be measured, what we found with real data and what we still do not know. Because a result that only shows its hits is not science: it is advertising.
