[Science] Journalism is about not taking sides, or about being a cheerleader. It's about shaking the tree, about asking award questions, about standing in the place of those who can't ask such questions, and being persistent, unpopular and dogged. It's about moral authority, something science in BBC News has lost...
Science and science journalism are needed. Journalists should portray where the weight of evidence lies, but that is the least they should do, and they should not look to scientists for guidance anymore than an artist asks a bowl of cherries for advice about how to draw them!
They should criticise, highlight errors, make a counterbalancing case if it will stand up, but don't censor, even by elimination, don't be complacent and say the science is settled in areas that are still contentious. The history of science and of journalism is full of those reduced to footnotes because they followed that doctrine.
