Why this site exists.
Reading Humans is a long-form reference for the modernised five-type constitutional framework. It serves three jobs: a place to take the assessment that produces a shareable result; a place to read the framework carefully enough to take it seriously; and a place to verify, when a curious person finds the Chrome extension or the iOS app, that the underlying material was thought through.
The site is descended from Elsie Lincoln Benedict's 1921 work Human Analysis, modernised, stripped of the parts that did not survive a century of scrutiny, and put on contemporary biological footing. The origins page documents the lineage. The limits page is explicit about what the framework can and cannot do.
Why I made it
I have spent enough time around groups of strikingly different people that the question of what kind of difference we were running into kept recurring. The Big Five gave a thin, empirically defensible vocabulary that did not, in practice, help me read a room. The popular systems — Enneagram and MBTI — were worse than thin: the first an over-extension of Jung into mysticism, the second a distortion of Gurdjieff's body / emotion / intellect typology with the body removed and a magazine quiz dropped in its place. Neither stayed in my head because neither was looking at the body. The constitutional framework, which does look at the body, has stayed: I find myself using its categories in the working week, not because they predict anything, but because they let me notice what I would otherwise walk past.
The 1921 source has obvious problems and is not a book I would recommend without caveats. But its observational core is sharper than its reputation, and its language for the orientations is durable. The modernised version on this site keeps the observation, sets it in contemporary biology where contemporary biology bears on it, and is honest about everything the framework cannot do.
Companion products
Two related products extend the site. The Chrome extension applies the framework to long-form text — emails, essays, drafts — using LLM analysis of writing style as a richer signal than the assessment can provide. The iOS app ships the assessment natively for phones. Both share the same backend data files with this site, so the framework stays consistent across surfaces.
