News organisations follow specific procedures when they get something wrong, and those procedures often look slower or more formal than readers expect. The reason is that the published record has to stay intact.
The archive is the reason deletion is rare
A published article becomes part of a record that others cite, link to and rely on. Removing it silently breaks that record and hides the error rather than resolving it.
Standard practice is therefore to amend the article in place and attach a note explaining what changed and when.
The note serves readers who encountered the original version, since without it they have no way of knowing the piece has moved.
Errors are classified before they are fixed
Most policies distinguish between a factual error, a matter of interpretation, and a story overtaken by later events. Each is handled differently.
A factual error attracts a correction. A subsequent development attracts an update, because nothing published was wrong at the time.
Blurring the two is what causes disputes, since labelling a development as a correction implies fault that did not exist.
Severity determines how visible the fix is
A small error in a detail is generally handled with a footnote, while an error affecting the central claim requires prominence comparable to the original.
Where a story was promoted heavily, a correction confined to the bottom of the page reaches a fraction of the people who saw the claim.
Some outlets therefore issue corrections through the same channels that carried the original, including newsletters and social accounts.
Legal exposure shapes the wording
Corrections interact with defamation law, and in many jurisdictions a prompt and prominent correction affects the remedies available to a complainant.
Wording is drafted carefully as a result, stating what was incorrect and what is correct without adding characterisation.
The specific effect of a correction on liability varies considerably by jurisdiction and changes over time, which is why practice differs between countries.
Volume and speed create the pressure
Continuous publishing means stories are updated many times, and the version a reader saw may no longer exist in that form.
Some publications maintain version histories for this reason, treating the article as a document with a trail rather than as a fixed object.
The underlying commitment is that a reader should be able to establish what was said and when, which is the function every correction policy is built to serve.
