Abstract
In the groggy aftermath of the 2016 election, slightly more than half of Americans are still in shock. In an effort to understand not only how Trump happened but how they had so underestimated his appeal, editorialists have loudly pointed fingers at Facebook, which, according to a new Pew report, is now used daily by 68% of the American population. Facebook, they write, is uniquely responsible both for a seemingly unmitigated spread of fake news and for serving up news stories that fit users’ own beliefs, trapping us all in our own filter bubbles.
