the best source of news is a source that you trust to be true and accurate
That is not true. The reason it is not true is that truth does not care if _I_ believe the source or not.
If NewsA is something I trust, does not mean they are telling the truth. It only says something about MY trust, not if they should be trusted.
So what is the solution? First you need to have multiple sources. They need to be independent from each other. e.g. not one paper and another one owned by the same company. If possible they need to be as far apart as possible. They can be from different countries.
e.g. Foxnews, CNN, BBC and Al Jeziraa. If there are any that you detest, good. And now you can start to think for yourself. Also: do not limit yourself to these and understand that the truth is also not interested in amount of people who say something. Just because 3 f the sources say something does not mean they are wrong.
The self thinking comes from the fact that you will start to notice that one source might be telling more lies than others, You will also start to realize that many articles are almost identical and the wording is just a bit different. This often means that they have it from the same source, like Reuters or a press release.
So if you not have the time to do your own research, you are screwed, as you do not know upfront what sources depend on their reputation and which ones depend on hype.
