One of the first rules of journalism should be to leave yourself out of the story. I do think we have some strong reporters who do that but the facts/information leans one way and so the other side calls them bias.
At this point a lot of journalists have a hard time not being part of the story themselves and it is all opinions based not facts. Our president shoots down facts all the time as bias and it has created this churn of blaming journalists for everything when they are just saying what is happening.
My entire professional career so far has been in different parts of the media industry. My general advice to everyone is always the same - trust and rely on your local news sources above anything else. Seek them out for most of your information. Treat national news as more of an appetizer or salad to your main course, the main course being local news.
Humans manage the media industry and humans are biased. Mistakes and lapses in judgement will happen so we have to expect this. Some news entities are simply better than others in this regard, though. The New York Times and Wall Street Journal are pretty good national brands. In Nebraska, the OWH is objectively the best and most consistent news outlet. But, again, they all make mistakes.
Another really good source is the BBC. They have an American version, but they maintain high journalistic standards (moreso than a lot of American sources).
But, one of my rules of thumb. The more a news source spends trying to convince you they are the only source of the truth and everyone else is fake.....usually it's the other way around.
