Sometimes the coverage of topics is poor in facts, but presents narratives instead. If you look at different sources, you might find multiple narratives, but which one of them is true? Is any of them true? To be able to judge the truth of narratives we need to know the facts and understand the theory (or theories) of the subject area. Then we'll be able to see what's important and make conclusions and predictions.
The best way to discover facts is direct experience -- when it's possible and safe, experiencing the thing yourself is irreplaceable. When that's not possible, collect the (claimed) facts from existing sources of information, preferrably the ones close to direct experience.
To learn the theory read serious literature on the topic, take courses, talk to experts.
Finally armed with the facts and theory we can try to make sense of it all. Which facts are the narratives emphasising? Which ones are they omitting? Does their version of the story fit with the theory? Does it still hold water in the face of the omitted facts?
It's better to ask concrete questions and then try to answer them (preferrably writing it down, see [2]) instead of following the stream of news or tweets (as addictive as it is).
