I don't go that far. I tend to look at a few things: * what is the source? do they have a reputable history? * do they have conflicts of interest? * do they have a history of faithfully printing retractions and admitting mistakes, or a history of exaggerating facts? * do they have a history of writing accurately about subjects I am an expert about? (e.g. subfields of computer science) If they score pretty well, I tend to believe in the facts (and evaluate the interpretation) they espouse until I come across something that contradicts it. So far the only source I regularly trust is the Economist, but I haven't researched the history of many news organizations. It's just a starting point for me.
