As mentioned previously, you have to read opposite publications to know what is really going on, the Guardian/Daily Mail, BBC/Fox, etc. Also blogs and forums are becoming increasingly relevant if you can find your way through the maze of good and bad info. Many of these modern disseminators of information have really good sources who wouldn't ordinarily deal with the legacy press.

A good example would be the US election/Russian collusion story, there are two completely different narratives doing the rounds depending on where you source your news. Eventually one will be proved right while the other suffers the consequences of spreading lies.
