The Times’ rule is, we correct anything that is wrong, no matter how small or seemingly silly. And I don’t know any of my colleagues who would want to do differently. I hate to get any detail wrong, and when I do, I often have a moment of fantasizing about just letting it slip. But as I sat there that morning, kicking myself for a relatively small mistake that marred a story I had poured my heart into, it seemed so much worse to let it stand. Not correcting it would have undermined the credibility of the other 5,011 words of the story – at least for “My Little Pony” fans. And I think we have seen now that they are not an obsessive subculture to be taken lightly.
Another part of the Times’ corrections policy, which arose after the awfulness of Jayson Blair, is that each correction is entered in a tracking system that includes who was responsible, and an explanation of how the error came to be.
She tells how the error came to the newspaper's attention, how important it turned out to be in the context of the article, and her explanation for it. Link -via Metafilter
