Thank god someone is writing about this. Recently I've been on the Yahoo's homepage a lot, because of Fantasy Football, and I noticed that a lot of the content is exactly like the article says, fake news from right-wing propaganda sites. And no, this is not me expressing my liberal bias. It's one thing to have opinionated headlines like the Huffington Post, it's another thing to have a completely fictional headline c…
They really should filter the news to each person's individual bias. It'd just be easier that way. Cognitive dissonance is real and it can cause serious emotional distress. That's not a good way to drive engagement.
I suspect this is an excellent heuristic for a media organization to become popular.
However I also don't like it because it would limit the range of thought. Most things that I find interesting are at the peripheral or in the cracks, intersections, oddities, peculiar facts.
Without countervailing narratives you don't have a benchmark for topic variance, and like the OP, become incapable of believing there even exists alternative models of reality.
In a relatively non-partisan example, I find that people who believe in God don't really understand atheists. Surely deep down these people believe in The Creator. I also find that secular oriented types do not really believe that religious people believe. They think they are faking it on some level.
These are serious, even dangerous errors.
So I submit that we need, require, something I'll label The Truman Clause or Exit from the Matrix. I do not know what that looks like in an ethical information aggregation system. I suspect it exists as part of meta-cognition in either our culture or in the human brain, since one of the most important functions of higher learning is to teach you to question your premises.
More so than any elite university I've seen, the kind of culture developed at LessWrong is perfectly suited to tackling these kinds of meta-cognition issues.
