Scott Rosenberg, the media critic and co-founder of Salon, writes in the PBS MediaShift Idea Lab that newsrooms have a credibility issue they can address. He notes that about half of all stories contain errors but only about three per cent of them are corrected.

He has some basic prescriptions to restore and redevelop trust:

1. Link out. Let people see what you've researched.
2. Show your work and let it be iterative.
3. Let people help you identify and fix mistakes.

Rosenberg says four problems beset newsrooms in grappling with their shortcomings: tools and workflows aren't up to the task, there is denial and avoidance, readers are seen as adversaries, and the business is obsessed with the business.

How do you think media can more effectively deal with errors?

New York University's Jay Rosen never fails to be instructive, but his latest lesson is an intriguing exercise in self-criticism.

Rosen sent an errant Tweet this week on seeming corporate pressure involving a subsdiary of AOL --- what he calls "a serious error" --- and he has not only corrected the 140-character mistake but provided an extensive chronology of its pathology.

Before Rosen could correct, his Tweet had spread to a six-figure audience. He found undoing the mess problematic, in particular the weight of making a mistake with his professional credentials behind him.

His case study of his foul-up is an excellent example, though, of how to thoroughly explain how a mistake was made and his thinking along the way. Rosen has Tweeted 15,000 times, but this acknowledgment does nothing to take away from the contribution he has made. If anything, it enhances it.
