Corrections policy
Material errors are corrected visibly, not silently.
Request a correction
Use the corrections and contact form to send the article URL, the disputed statement, supporting evidence, and an optional reply address. We collect only what is needed to assess and document the request.
Corrections and updates
Material corrections identify what was wrong, what changed, and when. Articles retain publication and modification times and version history. Routine style changes need not carry a correction note.
Retractions
A retracted article remains at its URL with a prominent notice, reason, original publication date, and retraction date. Its headline and sharing metadata must not continue a misleading claim.
