# i gave claude my reading list Published: 2026-03-16 URL: https://diegoprime.com/blog/claude-reading-list i have a [page on my site](https://www.diegoprime.com/books) where i log every book i read. title, author, date, and a rating from 1 to 3. nothing else. no reviews, no notes. i pasted the full list into a fresh claude instance. no memory, no prior conversations, no system prompt. just the raw data. i asked it to build a probabilistic profile of the person behind it. it told me some things i was amazed at. i don't mean the obvious stuff. it'd be easy to guess im mexican, in tech, etc. i mean things like: - it knew the type of music i listen to while working - it knew my love for philosophy came before my ambition and entrepenur things - it knew pretty much how my work setup was (like, detailed) - it knew my biggest fear - it inferred my aesthetic sensibility - it reconstructed an emotional profile that was pretty precise a few hundred data points, zero explicit self-desciption, and it reconstructed things that are genuienly impressive. it also got some things wrong ofc. age 27 vs 21, but minor shit. the hit rate on non-obvious predictions was genuinely unsettling. what impresses me isnt the surface-level stuff. its the non-obvious predictions. in [my last post](https://www.diegoprime.com/blog/density-of-intelligence) i wrote that intelligence is pattern matching and that llms are unreasonably good at it. this felt like a live demonstration. i didn't tell it anything about myself. it told me about myself. what the fuck. now im doing this with my entire youtube watch history. as is
