How social media filter bubbles and algorithms influence the election

One of the most powerful players in the British election is also one of the most opaque. With just over two weeks to go until voters go to the polls, there are two things every election expert agrees on: what happens on social media, and Facebook in particular, will have an enormous effect on how the country votes; and no one has any clue how to measure what’s actually happening there.

“Many of us wish we could study Facebook,” said Prof Philip Howard, of the University of Oxford’s Internet Institute, “but we can’t, because they really don’t share anything.” Howard is leading a team of researchers studying “computational propaganda” at the university, attempting to shine a light on the ways automated accounts are used to alter debate online.
