I see two big, big problems here:
1. People getting their news from social media services that are not even nominally bound by any sort of journalistic integrity. Amidst allegations of liberal favoritism, Facebook recently said that, in addition to trending topics and modest human curation which is supposed to be unbiased and minimal, news feed content derives from algorithmically cherry-picked stories; said cherry-picking is conducted with the goal of keeping the user engaged and/or happy [citation needed, I know -- I can't find it]. Unless the user is a psychopath, they're unlikely to get a very complete picture of current events if they only see news stories that are pleasantly interesting. Facebook is neat, but the content it displays to users is unabashedly influenced by what is popular and/or fun, and therefore not a reliable (complete) news source. That said, since mass media is largely fueled by ad revenue and/or ratings systems, even the most reputable sources are prone to sensationalism (this is obviously not new), which segues nicely into the next point...
2. People aren't checking citations. Regardless of where you get your news, knowing where a story came from is critical: in the absence of some sort of magically unbiased, 100% honest and trustworthy news outlet (I'm waiting for Newsbot AI, programmed by a different and very dispassionate AI to remove human bias entirely), the best we can do as readers is to compare multiple (ideally oppositely biased) news sources. If you ignore the citations, not only are you devaluing the very notion of citation (and, by extension, journalism), but you're also missing the particular shaker of salt you probably should be taking a given story with.
