The only solution for a thinking person is to read widely and synthesize all your knowledge into a slightly more accurate picture of the whole.
Social media and fringe alt media can be bad for people with cognitive issues, but that’s not a reason to get rid of them.
(Note, there are many times when both the MSM and most of the alt media present a distorted picture! I would argue the ongoing Iran crisis is one of those times.)
I respectfully object to this. I’m thinking of research that was done a few years ago, measuring American’s knowledge of current events. The folks in the research that leaned right were generally more informed - meaning, they knew about a lot more currents events. But they were also overwhelmingly wrong about what they ‘knew’. Further, folks on the right tended to rate themselves higher than left-leaning folks wrt their knowledge, even though they were wrong a lot more.
