The AI Files · How leucotomy/lobotomy became Nobel-era medicine — then a repudiated cautionary tale · 1935–2026
A Nobel Prize and a magazine cover made cutting the frontal lobes feel like modern mercy — until the drug era and the outcomes caught up.
Invention, asylum demand, prize, collapse.

The story
Chapter 1
This nest tracks how lobotomy/leucotomy became elite medicine — Nobel and all — then a cautionary ruin. Lead with Moniz materials, Freeman-Watts practice, asylum demand, and the chlorpromazine turn. [1] [2]
Sincere therapeutic hope is on the table. So is showmanship. Not a cartoon, not a COVID page. [3]
Chapter 6
Keep primary statutes, court opinions, institutional archives, medical journals of the era, and later repudiations on the claim spine. Mainstream labeled mainstream. Rival paths steel-manned. No Grokipedia. Not a COVID culture-war page. [3]
Sincere belief that the science of the day justified harm is part of the epistemology — not a cartoon-villain shortcut. Knowing fraud is a rival reading where the record supports it. [@{tag}]
Chapter 7
Map sincere-consensus, capture/abuse, transnational imitation, and later rights-repudiation paths. State mustBeWrong for each. [@{tag}]
Chapter 8
Twelve dated nodes, one primary URL each, two-sentence opposing steel-man. READING + tl-graph mandatory. Wait rather than ship lean. [@{tag}]
Chapter 9
Documentary and hearing clips belong in sources — labeled primary footage versus dramatization/commentary. [@{tag}]
Chapter 10
No lean ship. Dense entries, >=50 timeline dates, people, critical path, rival theories, memory, READING, real documentary covers. [@{tag}]
Chapter 11
Pair sibling Medical & Science Sway nests and sister Science & Medicine (Tuskegee) for method — not a hate page and not a claims board. [@{tag}] [13]
Chapter 12
Unknowns stay labeled unknown. Prefer waiting over invented certainty. [@{tag}]
Chapter 13
Track framing from consensus fashion through embarrassment, rights revolution, apology, and classroom caution. [@{tag}]
