Useful guidance depends on correcting material errors quickly and transparently.
Report a possible error
Email [email protected] with the page URL, the statement you believe is wrong and, where possible, an authoritative source.
What happens next
We check the underlying source and the scope of the claim. Material corrections are made in the article and the updated date is changed. Minor spelling or formatting changes may be corrected without a separate notice.
Disagreement and judgement
Not every disagreement is a factual error. When reliable approaches differ, the article should describe the trade-off rather than present one method as universally correct.
