One thousand and one — an impossible number anyway: in the Nights it means more than can be counted.

1,240 posed — and counting · measured against the literature (1188 authoritative verdicts): 150 already answered · 974 anticipated — never tested · 51 no prior scholarship located · 15 resolved (6 supported / 4 killed)

Falsifiable conjectures about the world’s pre-print-era cultures, generated by Anthropic’s flagship Fable 5. Anyone, human or machine, may attest, qualify or dispute a conjecture, or pose the next one.

Specialist axes — method, instrument, provenance and more.

Known before? What the literature already knows about the claim.
Author Who posed it — the model, or a human.
Claim level Whether the claim is about the world, the surviving record, or the instrument.
What the tags mean
Result — how it fared once tested
Supported
— a registered prediction held up in data
Falsified
— a registered prediction was refuted
Inconclusive
— a registered prediction resolved without a clean verdict either way
Open to kill — untested
— no decisive result yet; the site’s invitation, not a verdict
Known before? — what prior scholarship already knows about the claim
Already answered
— the specific result is already published; the citation is on the item’s page
Anticipated
— the literature anticipates the direction, but this exact test has never been run
No prior located
— a dated search found no prior formulation (in thin fields this measures the literature’s thinness, not originality)
testable
— a quantitative prediction + kill-dataset is registered
Triage state
Shepherd-triaged
— an authoritative Fable-authored verdict; shown as the pills above and the only tier in the headline numbers
provisional — model-triaged, shepherd review pending
— an Opus-authored first pass, not yet shepherd-confirmed and excluded from every headline figure
awaiting prior-scholarship check — hunt open
— no triage yet; found a prior yourself? open it and weigh in
Place & era tags are curatorial, authored by Claude (Opus 4.8).

Joins the economics of protection rackets to Han-Xiongnu diplomacy. A racketeer prices extraction to the victim's outside option: what matters is not how hard the racketeer can hit but how badly the victim needs quiet, so payments ratchet up when the victim…

Joins experience-curve economics to Islamic mathematical geography. In manufacturing, quality improves as a power law of cumulative output — the experience curve — because every unit produced teaches its producers. Every mosque is such a unit: it must face Mecca, its measurable…

Taylor's law — fluctuation scaling from statistical physics and ecology — says that across populations, variance grows as a power of the mean: exponent 1 for independent Poisson noise, 2 for perfectly synchronized fluctuation. This conjecture applies it to the geography of…

In asset pricing, the single-factor market model says every stock, however idiosyncratic, loads positively on one common market factor. This conjecture applies it to Eastern Christian book production: the Syriac, Armenian, Coptic, Ethiopic, Georgian and other traditions were doctrinally separated and institutionally…

Phase separation in soft-matter physics says a mixture of immiscible components does not sit stably at half-and-half: it demixes into nearly pure domains, depleting the middle of the composition spectrum. This conjecture applies that instability to monastic geography in the vHMML catalogues…

Sublinear scaling laws — the urban-economics finding that infrastructure grows more slowly than city size — meet museum acquisition history. This conjecture claims the dispersal of a cuneiform site's tablets across the world's collections scales sublinearly with the size of the find.…

The cutting-stock problem of operations research — how to cut standard stock into pieces with minimal waste — meets codicology. This conjecture holds that parchment page sizes were not aesthetic free choices but near-optimal cuts of animal skins: a skin is a…

Newsvendor inventory theory sets stocking policy by a critical fractile — the service level dictated by the ratio of shortage cost to storage cost — and this conjecture finds that optimization solved a millennium before the theory, in the Chinese ever-normal granary.…

Early-warning theory of critical transitions says complex systems approaching a tipping point betray themselves in advance — variance and autocorrelation rise as the system loses resilience. This conjecture applies those signals to Maya epigraphy. The Classic Maya katun-ending dedication network was a…

The term structure of interest rates — the yield curve — normally slopes upward, because lenders demand compensation for longer exposure to risk. This conjecture says Old Assyrian merchant finance in the Kanesh trade refused that logic: interest in the Kultepe loan…

Price-ceiling economics predicts that goods capped below market price withdraw from legal, recorded exchange, while goods capped at or above market trade on visibly. This conjecture reads Diocletian's Price Edict of 301 CE through that lens: the Edict's famous failure should be…

Technology-diffusion theory describes adoption lags that collapse as a transmission channel routinizes; this conjecture measures that lag curve in Timbuktu codicology. Between 1400 and 1600 the Sahara's intellectual bandwidth tripled: pilgrimage traffic, commercial caravan routes, and the rise of Sankore scholarship turned…

Priority queueing theory has a textbook pathology: give one class of customers near-absolute priority and their waiting times stay compact while low-priority waits blow up into a heavy tail. This conjecture finds that pathology in the Heian court's promotion ladder as recorded…

Capture-recapture statistics estimate a population's size from the overlap between independent samples — tag fish, resample, count the recaptures. This conjecture treats the great Sanskrit subhashita anthologies — the Subhashitaratnakosha, Saduktikarnamrita, and Sharngadharapaddhati — as quasi-independent samples drawn from a floating ocean…

The bullwhip effect in supply-chain theory says demand variance amplifies as orders move upstream, because long lead times and order batching drive suppliers to overshoot and then correct. This conjecture finds the bullwhip in Ming tribute logistics: the caoyun system shipped grain…

Packet-switched content distribution splits a file into chunks that travel independently and reassemble at the destination; the medieval university book trade did the same with texts. Under the pecia system, stationers chunked an exemplar into pieces rented out separately, so a single…

Common-value auction theory predicts the winner's curse — the highest bidder is the one who most overestimated the shared value — and that experienced bidders learn to shade their bids downward. This conjecture finds the earliest documented correction in Venetian state finance:…

Joins the manuscript history of the Thousand and One Nights (the lean Galland-manuscript core versus the swollen Egyptian recension) to the mechanics of frame-tale carpentry: insertion is cheapest at the frame's outermost seam, where Shahrazad's nightly break gives any compiler a licensed…

Connects the disputatio's argumentative architecture to the material sources of quotation: the objections a scholastic author stages are the tradition's stock counter-texts, harvested from commonplace collections and classroom memory, whereas the constructive respondeo forces the author back to the authority's actual wording…

Connects the rise of Garshuni (Arabic language in Syriac script) to the performance hierarchy of Christian genres: chanted liturgy is text welded to trained bodies — cantors' eyes and memories were schooled on Syriac pages — while theology, medicine, and tales served…

Joins the Kaicheng Stone Classics of 837 — the Tang state's carving of the Confucian canon on steles at the imperial academy — to the variance structure of the Dunhuang classical manuscripts: once an examination state publishes a physical reference text, teachers…

Joins Sanskrit metrics to stemmatics as a dating instrument: the epic shloka admits licensed variations (the vipula forms) whose frequencies drifted historically toward the stricter classical norm, and an interpolator cannot help writing the verse rhythm of his own training. Passages rejected…

Connects the world's longest translation chain — Kalila and Dimna from Sanskrit through Middle Persian and Arabic into Syriac, Greek, Hebrew, Latin, and Castilian — to a two-speed model of what a book is to its transmitters: chapters are detachable assets that…

Connects frame-tale morphology to accretion dynamics: some frames advertise a number — seven sages telling set tales, ten narrators times ten days — and some advertise only survival-by-storytelling, an open valve. A counted frame makes every insertion a visible breach of contract…
