> Social and psychological forces are combining to make the sharing and believing of misinformation an endemic problem with no easy solution.

There's nothing new about misinformation in the US. We have a long history of trying to influence each other for monetary, political, or other purposes. (See 19th century newspapers completely ignoring news not favorable to their chosen parties and candidates).

Maybe it happens faster now with social media. But the effect has been with us before and will be again.
