If you can spot a typo in the first few seconds of reading a piece, so can the editor and sub-editor before it's published.
I can only imagine the same thing happens in newsrooms with text, especially when it is visibly very similar, like "2002" and "2022."
Sometimes this results in radical changes to a piece within hours of publication - yesterday for instance the BBC ran a piece headlined something like “I watched my father murder my mother”, and six hours later in slides an editorial correction saying “she did not, in fact, see her father murder her mother. She was asleep in another room at the time.”
