There's a big part of the argument here that is that what is and isn't misinformation is largely unknowable by any individual, and that different people disagree on different experts' authority.
But that's just not true.
It's true that there is no easy solution, but that's because it's an education problem. When Bob and Steve think Infowars is a more reliable source of information than the journal Nature, Bob and Steve are just wrong, and we shouldn't help them make other people also-wrong, and we probably should try to prevent them from confusing other people too.
It's relatively easy to learn enough science to be able to correctly distinguish the 10% most extreme dis/mis-information. The amount of effort we're putting into getting people just to that level, as a society, is extremely low.
