Actively and without consequence? No. Simply maintain self control and realize that the more dialog is open, instant, and global, the more it is subject to the loudest and most manipulative. Not necessarily ideal, but better than alternatives.
It's a can of worms, especially in a country that is as suspicious of it's government as America, but in my view, one of the biggest changes in people's views of the media (and "truth" in general) is the steady erosion of Journalistic standards - putting infotainment shows and opinion pieces on the same level of journalistic rigour as actually well written, high standard news stories.
News corps will continue to chase money, and money is tied to viewership - which gains from people being engaged through polarising, emotion driven content.
If there are no standards for this kind of thing, people will gravitate towards the stuff that gives you that hit of emotion, and they'll forgo and bend facts to present a story in a way that keeps their viewers at the expense of fair representation of facts, and bias.
In the context of social media, it's tricky, because robo websites and opinion pieces run rife through them, with pieces debunking them and/or apologising for incorrect facts not propogating as hard - so in my view there needs to be some level of targeted/intelligent regulation of social media as a news source. (Content aggregators perhaps taking some level of responsibility of curating what is being shared? Admittedly difficult to do this without getting Orwellian...)
But that's just my opinion, interested to hear if people think it's a load of BS or not.
Is there something Congress should be doing? Perhaps it's not the thing for them to be involved in.
Paul Frazee's 2018 JSConf EU talk on "Formalizing User Rights on the Web" makes an important observation: technology doesn't just interact with civics, it actually drives civics; it defines what the civic structure of a community is going to be (https://www.youtube.com/watch?v=x-ffpAkviM0&t=920).
That there's a serious problem has been obvious for quite some time now, and Silicon Valley has hardly even tried to do anything about it. More likely, they've tended to tune their algorithms to best profit from it.
I'm a small government guy, but if they continue with this disingenuous "we had no idea!" song and dance for much longer, I'd fully support bringing a very big hammer down on the bigger players.
The public airwaves are regulated by the FCC. There is no reason to pay broadcasters to prevent some candidate from becoming elected.
