The problem with "both sides" in the modern media is not that they present both sides - with, obviously, one side being wrong - and leaving the decision who is right to the people. The problem is that above sides lie, and lie consistently, in the same direction, so that the lie is the consensus, and not what is argued about.
So, like in Hitler time you can imagine a "both sides" discussion between those who propose to gas Jews and those who propose to expel them to Madagaskar, you can have, today, argumentations how one should support Ukraine in their fighting against Russian aggression, or how to get rid of Assad. (Or how the state should fight racism or homophobia, forgetting that a liberal state should not care, not influence with taxpayer's money, what people think).
Maybe we are not that different here, because this is also an issue with "bothsides bullshit":
BTW, neutrality is not at all a necessity for a good "both sides" format. Fairness is.
Both sides of the media present truth, however both sides also use data tricks, to manipulate how their audiences interpret the truth. As an example, if I only pointed out bad things about you, an audience can be made to go against you. If it was properly proportioned truth that paints an accurate picture then the audience will see someone else. In this case, all the data can be true, but one sided truth does not paint a complete or balanced picture of you.
If I showed you nothing but plane crashes ,while ignoring millions of flight hours that are safe, people can get the impression flying is less safe, than the full data set suggests. I can compound the impact of this data stacking, if I have a fleet of experts, reinforcing the doom and gloom, but not the whole truth.
As another example, CNN will willingly report the Russian hacking of the DNC. This is true. However, you will not hear them say much about how Hillary and the DNC, never denied the authenticity and content of those hacked e-mails. The things in the emails, were truth that was never supposed to be released and are being ignored once again. That hidden truth changed the picture of Hillary and the DNC and had an impact on the election. Now CNN is trying to change that more balance picture, back to the victim card, with no mention of the scam artists behind the curtain. Like in a magic trick, the audience is induced to look over there, so the magician an his assistant, can do trick.
What Trump should do is make a distinction between freedom of the press and freedom of speech. All reporters and all news agencies have freedom of speech. However, if they exceed certain limits of balanced truth, they get their press credentials suspended for anywhere from days to years. They can still play the data game, as citizens, but will lose their license to deceive in an official press capacity.
One way to quantify this is to rate new agencies and news reporters based on what they have said, in the past,based on how history played out. For example, all reporters who said Trump will never get elected, get a D for that. Then we average the grades and post these for everyone to see. We have the benefit of 20/20 hindsight to grade the media based on past performance in news reporting. If they like to pass gossip of truth this will lower their grade. The grading system will cause the free market to drift audience in the direction of higher news value. This will hit owners in the pockets, and they will makes changes based on being accurate and balanced.
We have the EPA to protect us from pollution of the earth, why not an agency to protect citizens from news pollution? Wouldn't it be better if you could tune into any news station and expect fair and balanced news, instead of propaganda wings of political parties?
On the other hand, people react better to entertainment than to education. Many people like lopsided news since it will induce emotions, which is part to the entertainment package they seem to crave. Many want their biases reinforced.
