sigh Has anyone stopped to think that actually this might just be mirroring human nature? We select our friends on who we trust and agree with. We don't actively find a friend "to provide a bit of variety in our views and opinions" (well, some do, but they tend to be vein and don't shut up about it) The secondary part to this problem is the lack of shared news sources. We like in the middle ages now have effectively have out own vicar for each friendship group. They are the arbiters of moral decency. (only travellers could compare and contrast, and they kept them selves to themselves) The rise of specialist "view" news, motherjones/breitbart to use two extremes sell the same news but with the facts warped to fit their own world view. This has always been, but with the rise of competition, the extremes win(because they angry up the most blood, and get the most clicks) The thing that ties a country together is a sense of shared values/truth. With the explosion of custom news sources, leads to diverging values. In short there are two problems here: Human social network theory, and the desire to make money through news.
