"Sold out" is a real problem. More people than we want to admit see corruption coupled with big media as a enemy, not a thing to be trusted. Many ordinary people flat out do not know when to trust, so they don't.
They then seek others and continue to have conversations, and they find others lacking trust resonates and that opens the door for a lot of BS normally and easily seen.
Just an example of the difficulty we now face:
Hiding YouTube dislikes will, among other effects, serve to help big corporate media compete against new media.
Hiding the dislikes also breeds more mistrust. This is unavoidable no matter how reasoned the move is.
Public trust in corporate media is really low, and the younger a potential user of that media is the worse those metrics are.
Had that same media held more closely to journalism, rather than access journalism, which is essentially a sales job, the trust problems we struggle with today would not have grown into the chronic problem it all is today.
You identified politicians committing similar abuse of the public trust.
Look at Russiagate. Basically, it flat out did not happen the way many believed it did. Back when that started, many and myself included went to the original documents, saw speculation and in some cases saw it helpfully color coded, and turned on the news only to see all that elevated to fact.
That scared me frankly.
What can one conclude?
I do not see how judging others helps right now. Not saying anyone did here, but I am saying that is happening a lot and when it happens the door for good info to find it's way home gets closed. Advocates render their efforts far less potent.
Secondly, the lack of trust really can't be assigned to people. We have a lot of "they are stupid" type discussion, judgement and rationalization going on and very little of that is helpful.
ie: 70 million people voted for...
The people who had a far better position of authority and trust denigrated that themselves, and for dollars and ratings.
All that is a real mess!
How can authorities, who have abused public trust be counted on to fact check and improve on misinformation without amplifying the already chronic trust problems they created?
In a more basic sense, how can we improve on public trust at all?
I am not sure how that is done quickly.
Longer term, we need media that makes informing people a priority. And doing that likely means a move away from the current AD and access based media we have now.
Given how things are right now, the more important thing is to avoid judgement of others and encourage more and better information exchange. We will not know what reaches people, until it does.
Once it does, we need those people to continue seeking better information so we see more people making better choices more of the time.
