Interview with Nora Paul of the Poynter Inst. Nora runs Poynter's programs related to new media and computer-assisted reporting. Her extensive background as a news researcher includes 12 years as library director for the Miami Herald .
Credibility is in the eye of the beholder.
To me, a news story is credible when the reporter has found and interviewed sources who either are credible, or else they have been put into appropriate context. Also, I look for whether the reporter interpreted the responses from the interview well. I personally don't believe that the myth of objective reporting is anything more than a myth. Credibility is in the eye of the beholder. Someone who witnessed the same event that a reporter did won't see it in the same way as a reporter does.
