What distinguishes journalism...?
All research and informative writing is only as good as the source and objectivity of the writer. This is particularly true in journalism - often called the Fourth estate or branch of government- which should bet sources for integrity and present ideas without bias.
Neither, however, is perfect. It is impossible to completely remove one’s bias . So in an attempt to correct for this journalists had typically (although to great detriment not so much anymore) used the two source corroboration test: find two completely different sources from two completely different views, fields, perspectives, etc. that tell the same story.
This method prevents a journalist from only selecting the one source that confirms their bias and also checks the story for integrating by providing corroboration.
