Corrections policy

How corrections work

Nothing is edited in place. Every published article is one revision in a history of revisions: a correction produces a new, reviewed revision rather than a silent overwrite of the old one. Each article shows when it was published, when it was last updated, and when it was last reviewed, so a reader can see whether the version in front of them is current.

What gets corrected

• Factual errors, however small, are corrected once verified.
• New public information that changes a previously unconfirmed or estimated figure is added, with the article updated to reflect it.
• Any change to a claim, a source or an image invalidates the article's existing editorial approval: the change goes through the same human review as new content before it is published, it is not applied automatically.

Report an error

If something on this site is wrong, out of date, or misattributed, get in touch through contact with a link to the article and a description of the issue. Corrections are made once the correct information can itself be verified against a reliable source.
