Do we really need another bitch?

The infamous Korean scientist who previously claimed to have cloned a dog is now reporting that he and his team have cloned a female dog. This, of course, leads many to suspect whether this announcement is credible and the bigger issue of how can a person regain credibility after being accused of lying (on top of ethical questions around cloning).

When I first saw the headline, I naturally scoffed at it and questioned the validity, but then I took a moment and thought about how much "truth" capital such a scientist will need to obtain in order to be seen as a credible scientist. This leads me to consider, what does it take to regain trust?
