Each story on this site is based on several reports from different publishers. Under the story summary we show what those sources agree on, where they differ and what was later not confirmed. We describe how sources agree with each other. We do not declare what is true or false.
Key claims
When a story is prepared, the language model that drafts the text also lists 3–8 key claims — a number, an event, a statement or a cause — and names the sources in which each claim appears. Our software checks that each cited source belongs to the story and that the claim numbers and dates appear in its text. These checks do not determine whether the source semantically supports the complete wording; that still requires editorial review.
- A source must exist in the story’s source list.
- Every number and date in the claim must appear in the text of each source it is linked to (different formats such as 1,250 / 1 250 / 1.250 are recognised). If it does not, the link is removed.
- A claim with no remaining links is not shown.
Statuses
The status is calculated by our software, not by the model, from the number of independent publishers that report the claim:
- Confirmed — three or more independent publishers, and no disagreement about this claim.
- Partly confirmed — two independent publishers.
- Single-source claim — one publisher.
- Disputed — sources give different versions of this claim.
Several websites of one publisher count as one publisher. Nearly identical texts published by different outlets — for example, one news agency report reprinted by a group of regional newspapers — also count as one source, so that syndication cannot turn a single report into a “confirmed” claim. The system does not reliably detect translated or cross-language reprints, which may still be counted separately. We reviewed a sample of ten distinct production story histories, including updates. This sample is a structural review, not a guarantee that every claim is semantically supported. Public blocks are automated and must be read with the limitations below.
Where sources differ
If sources give different numbers, versions of events or explanations, we show the positions side by side with links to the publishers that hold them. We do not choose between them.
What was not confirmed
When a story is updated with new reports, earlier claims that were not confirmed by other publishers, were contradicted by later reports or were withdrawn or corrected by their source are shown crossed out in the story’s timeline, with the time of the change and links to the reports that show it. Earlier statuses are kept, not overwritten.
Limits
A status measures agreement between publishers, not the accuracy of events: several publishers can repeat the same mistake, and a single publisher can be the first to report something correct. Automated checks are limited to source membership, numbers and dates; they do not establish that the complete claim is supported, and can miss errors. If you notice one, please use the “Found a mistake?” link under the story.
