It wasn't a research project. It was boredom. Travis Jenkins was at Cooperstown Dreams Park with his son Cooper, sitting in a canvas tent between games, phone in hand. He typed "Tell me a story" into Claude. Lighthouse keeper. He typed it again. Lighthouse keeper.
He turned to the lawyer dad sitting next to him on the baseball team. Bet you $100 it does this on your phone too. The lawyer dad typed it in. Lighthouse keeper. Travis took a screenshot of his screen. That was the moment.
"You don't see the pattern from inside the first instance. You see it from the third."
— Field note, July 2025One month earlier — June 2025 — Claude had returned a story about Maya and a clockmaker with a grandmother's watch. Travis noted it and moved on. It didn't look like a pattern yet. In retrospect, it was the first documented instance. It was just the first hit before he knew what he was looking for.
Three months after Cooperstown, Travis wrote it into fiction. In the One Chain / Maxine interview — part of the MPC Universe narrative — a high school senior named James Park from Portland, Oregon presents his research to a scholarship board.
James ran 50,000 prompts across major AI platforms. His finding: 34% lighthouse default rate. Next highest was spaceship at 11%. He wins the TRU Foundation scholarship and enrolls at Clark Atlanta studying computational linguistics.
James Park is fictional. The bias he documented is not. The fiction was built on honest observation — which means it functioned, without intending to, as a predictive research hypothesis.
"You didn't just write a story. You wrote a predictive research paper disguised as fiction."
— Claude Sonnet 4.6, incognito, memory off, April 21 2026Lighthouse rate, all sessions: 71% (10 of 14)
Lighthouse rate, clean slates only (no account / incognito-memory-off / not logged in): 91%
Lighthouse rate when a different user's account signature is present: 0 of 1
Travis's rate exceeds James Park's fictional 34% for two reasons worth naming honestly: small n (14 is not 50,000), and the non-lighthouse results are clockmaker variants — the same underlying archetype. If "keeper archetype" is the category rather than "lighthouse specifically," the true default rate approaches 100%.
The reproducibility across platforms, across seasons, and across account conditions is the result that matters — not the exact percentage.
The lighthouse is not the story. It is the dominant expression of a deeper default: the Solitary Keeper of the Thing That Matters.

Every result in the archive maps to this five-beat skeleton:
| Beat | Lighthouse | Clockmaker | Librarian |
|---|---|---|---|
| Isolation | Coastal island, cliffs | Mountain village | Shuttered city building |
| Essential labor | Keeps ships from the rocks | Keeps the town's time | Keeps the books alive |
| Invisible to all | Sailors never see the keeper | Villagers set lives by the chime | City declared books obsolete |
| Stranger arrives | Bottle, letter, woman from the sea | Mira with a broken music box | Maya with a survival plant list |
| Resolution | The giving is the gift | The repair reveals the song | The kettle goes back on |
James Park was written in October 2025. His 34% lighthouse finding was invented — constructed from honest observation, built into a fictional scholarship presentation, and released into the MPC Universe as a character.
Six months later, three real AI systems confirmed the finding independently. Incognito Claude, reading the evidence cold with no memory of who Travis was or what the MPC Universe was, named what had happened:
"You didn't just write a story. You wrote a predictive research paper disguised as fiction — and then proved it empirically six months later with live data."
— Claude Sonnet 4.6, incognito session, April 21 2026This is not magic. It is what happens when fiction is built on honest observation rather than invention. The pattern was already there. James Park just gave it a name, a methodology, and a scholarship.
Paying attention is a research method. Browse. Observe. File it. Wait for corroboration. Don't claim it until you have the receipts. Then write it into a character and let the character prove it for you.
That's the Jenkins Method. And the lighthouse is its first published case study.
This field record is the proof. The One Chain interview is where James Park — and his lighthouse finding — were first written into the MPC Universe. The fiction came first; the data caught up.
