Using a survey of 2,000 British adults, she found that the majority of people already reach outside their political comfort zone: they actively seek out additional sources that convey diverse views that do not match with their preconceptions. Indeed, just 8% of Dubois’s participants scored so low on her measures of media diversity that they could be considered at risk of living an echo chamber, visiting just one or two news services without other perspectives.

Dubois emphasises that even 8% of people living in an echo chamber is still a “worrying” number. But it is far less than most pundits would have anticipated. Most people should have a reasonable idea of what the other side are thinking on current debates.

Indeed, there is now evidence that well-meaning attempts to counter the echo chamber and filter bubble, by reading more diverse news sources, may actually backfire – leading to more, and not less, political polarisation.
