Few people want to live in an echo chamber. Many have no problem being friends with those who vote differently to the way they do. And many would probably agree with John Stuart Mill that “he who knows only his own side of the case, knows little of that” – that to truly know one’s own argument, one must also know the arguments of those who disagree.
How to create a culture that encourages more fruitful engagement between those of differing political views has become a key question in contemporary public debate. Nowhere more so than in universities, where there has been much debate about “viewpoint diversity”, the aspiration to nurture differing and conflicting perspectives within an institution or group as a means of sharpening arguments and teasing out truths.
