Not entirely sure this is the best place to ask, but I'm looking for a word or phrase that I possibly heard a long time ago. It encapsulates one or two ideas:
The first (and possibly more important) idea is that the more you know about a subject or event, the more you see that news reporting on the subject or event is incorrect.
The second is that because of this, news reporting about something you don't know about should be treated with suspicion.
I thought there was a 'blah blah effect' or 'blah blah principle' describing this, but I've come up empty handed in my searches.
Edit: Maybe I'll clarify slightly. For example, if you know a lot about cars, it will likely seem that many news articles about cars contain incorrect details and factual errors. But at the same time, if you don't know much about computers, news articles will seem to make sense to you. But given your experience with the news about something you know a lot about (cars), you should be distrustful of the news about computers.
Maybe it was only in my head that there was a term for this. If not, I call dibs!
As a side note, if this is not the proper place to ask this, where else could I ask?
