But that's precisely the evolution we've seen in the past 20+ years. For the sake argument, let's say that Fox News started it by more overtly embracing a specific political alignment for stories and opinion programming. Then, MSNBC noticed and went the other way round. Then, "new age" outlets such as Breitbart News and HuffPo took that to its logical conclusion, not even pretending to describe reality and just focusing on portraying the other side as evil and dumb.

The end result isn't that we're more informed and enlightened as content consumers. It's that everyone has their own version of reality. The boring neoliberal consensus of the old had many downsides, but at least it provided some social cohesion in that everyone was more or less reading the same news.

I think Fox News is a good example, because their public messaging has always been "fair and balanced" while at the same time blatantly have a bias; this is just one aspect of how they are clearly deceptive. If instead of calling themselves "fair and balanced" they said they were all about "the Republican Perspective on News" they would immediately be more honest, and it would be easier to understand them as an organization, especially for the people who are regularly deceived by them right now.

I'm not arguing that we should try to exaggerate our biases, or even to center them, but rather, we can become more honest by making our biases clear and explicit to those we're communicating with. Many organizations avoid openly addressing their biases, which makes them less honest overall, and more prone to being deceptive. If you're aware of your biases you can actually account for them, as opposed to letting them blind you. Further, if you're public with that awareness, others can account for them as well, and be less likely to be deceived (even accidentally) by your communication.

Too often, bias is ignored. It always exists. If we name it and make it visible, then we can have a chance at reducing its potential for deception.
