How EquiWiki is made

Sourcing, and what (u) means

Pages are researched cite-and-link only, from studbooks, the WBFSH/FEI, established pedigree databases (HorseTelex, Hippomundo, rimondo), auction houses and reputable equestrian press. Every statistic maps to a source on the page.

Our standard is two independent sources. A claim is shown as verified only when two sources on different domains carry it, or when our two-model fact-check has confirmed it against the cited page. Anything resting on a single source is published with a (u) beside it.

(u) does not mean doubtful. A single source is usually the studbook, the auction house or the federation, and it is usually right. It means one party has said it and nobody independent has yet confirmed it — so we cite it, label it, and let you weigh it. We would rather show you the strength of the evidence than flatten every line into the same confident tone. As second sources arrive through enrichment, the (u) drops away on its own.

The evidence score. Each claim carries a number, and each page carries the average. It is built from things that can be counted and checked, not from an opinion:

• 40–55 — a single source, ranked by who published it: 55 for the FEI or WBFSH, 50 for the studbook that registered the horse, 45 for an established pedigree database, 40 for anyone else (an auction house or a stud is an interested party in its own horse).
• +25 — for every further independent source carrying the same claim, up to two. Two pages on the same website are one source, not two.
• +30 — where our two-model check read the cited page and confirmed the claim against it.
• 15 — a claim we hold with no citation at all.

70 is the pass mark, and nothing ever scores 100. This is an evidence score, not an accuracy score: it measures how well-sourced a claim is, never a probability that it is true. A well-sourced claim can still be wrong, and a lone studbook entry can be perfectly right. We publish the workings so you can judge the claim yourself — and so can any machine reading this page.

Independent verification

Before publication, every page is checked by an independent reviewer — a second AI from a different model family than the author, which re-checks each claim against its cited source. Pages that fail are rejected, not padded. A quiet hour is the system working.

Corrections

Spot an error? Every page carries a "Report a correction" link. Fixes are made by a human editor; significant corrections are recorded on the public changelog (a comprehensive machine-generated record is in the works). Studs and owners can claim their profiles to keep their data first-party.

Independence

No stud can pay for placement, a rosier page or a higher Breeding Index. Rankings come from the WBFSH and cited season standings; the index weights are versioned and public. EquiWiki exists to serve breeders, not advertisers.
