[…] That’s the point of the entire “it’s a real job” argument. Journalists are doing a lot of legwork once and we’re all relying on that job to acquire a lot of our information instead of all of us doing the same legwork again. The two problems we’re facing are 1) that this trust opens us up to propaganda from activist or opinionated journalism, and 2) that we’re no longer just getting neatly processed info that has gone through a journalistic process, we’re also getting a firehose of misinformation from many individual content generators over the Internet.

Those are both hard problems to manage.

I agree that they may be hard problems to manage perfectly, but I don’t agree that citing sources won’t put a dent in the issue. Take your first problem:

Say you have an article that says “A young man stole a car.”. Just as a very basic example, language like “young” is an opinion — it’s not an exact definition of age and is left to the reader for how they interpret it. Such interpretations open the door for emotional bias. I think it would be a different story if the article actually cited the age, or simply stated the age with a citation for where they know it from.
