I think there's a difference between not trusting the news, as in, thinking what they're saying is lies and there's actually a great conspiracy that we can work out, and not trusting the news, as in, thinking that the information that gets conveyed via news outlets is selected and presented to push public opinion in a certain self-interested direction.

I think for the most part, people who take their news from youtube and random taxi drivers fall into the former category, whereas people who vote against the party/candidate recommended (overtly or covertly) by their local paper fall into the latter category. It's quite possible that a lot of people in the latter category would say they don't trust the news as part of a national opinion survey, but they wouldn't ever outright say to a stranger "oh, don't read the stuff printed in the City Courier, it's all lies". Particularly as the news is more and more national, but the political parties continue to attract around 50% of the vote each, I'd generally expect about 50% of the population to have at least this much distrust for at least some of the news.

I have a different take on this.

Unless I am asking the taxi driver about traffic problem in their work area, or rider behavior, or...

We have become citizen journalists. We have to research our own news. I think that is not a bad thing.

I write journalist because if an establishment journalist can get away with single-sourcing something, why can't I?

YouTube is a cesspool of hot garbage, but there is also plenty of good information.

The key part in my opinion is to have the ability to collect, sift, confirm, and then make deduction.

Alas, we no longer teach fundamental thinking skills in schools.

Try this experiment: Read old news for a while.

You’ll quickly learn not to trust the news. Not because it’s wrong – it’s pretty factual for the most part – but because it keeps trying to make you care about the wrong things. Whipping up an emotional reaction to matters that don’t affect you. Ignoring large elephants in small rooms. Talking juuuust slightly past the core issue hoping you won’t notice.

Much of news, especially daily news, is like discussing the color of a bike shed instead of the core design problems of the reactor it sits behind. Because talking about the big stuff isn’t sexy and doesn’t get the clicks.

And even when you do find a source of boring news, you’ll find that most of it affects your life not one bit. It’s just entertainment to keep you busy. In the words of a quote I once heard and can never find again: ”The news doesn’t tell you what to think, it tells you what to think about”.

Indeed. People are replacing mainstream news with something that's often far less accurate.

Probably a selection bias at play. The people you meet who don't trust the news for reasonable reasons aren't going to come out and state it that simply because they don't want to be associated with the people who claim they don't trust the news because the have preconceived notions which they trust any source for (even if random taxi driver) and distrust any source against (even in peer reviewed research). They likely even purposefully consume the news, realizing that even as an imperfect information source it is still an information source worth the trade off between extent of imperfect and ease to consume.

If a youtube video shows a reality that the news denies or doesn't report, that should make you trust the news less.
