This may sound strange, but most corrections basically need a good PR team that goes beyond a corrections page, as the New York Times has been doing of page A2 since 1972.
When something is published and it is wrong, the first thing to do is own up to it. But remember you are human, as Craig Silverman makes a point of in his article. Move on by not just owning up to a mistake, but giving it a correction and further promoting the correction. Emphasize its “correctness” for the best results.
The best solution to making a mistake is this: don’t make it in the first place. Unfortunately that’s an impossible task, particularly in the fast-paced world of journalism. Instead all we can do is inform the public, using as many channels as possible, of what is correct in hopes that they will see and understand what went wrong in the first place.
