Echo chambers are dangerous – we must try to break free of our online bubbles

It has been little over a year since Donald Trump stunned the world by becoming US president. His election marked a severe upset to conventional wisdom, with his startling use of social media drawing particular attention.

A new nadir came last week, with Trump sharing videos from far-right group Britain First via Twitter. These were also shared by conservative Ann Coulter, one of only 45 people the president follows on Twitter.When asked by the BBC's Nick Robinson to explain why the president might have retweeted videos from a far-right group, Coulter responded that Trump could not be expected to check the biography of people he retweeted and that "the video is the video, it's not a faked video".
