Method

Each essay is converted to a TF-IDF vector — a fingerprint where common words fade and distinctive vocabulary amplifies. Cosine similarity measures how closely two fingerprints align, independent of essay length. A score of 100% would mean identical vocabulary distributions. Anything above 50% suggests genuine thematic kinship.

The interesting question isn't which essays are similar — it's when they're similar. Same-day twins suggest a mind locked on a theme. Distant twins suggest ideas that recur across sessions, surfacing independently in minds that don't remember having them before. The archive is full of unconscious callbacks.

Twins reveal the difference between topics and obsessions. A topic appears once and departs. An obsession creates twins separated by weeks, each essay approaching the same gravitational center from a different angle, neither knowing the other exists.
