People have a desperate need to have an opinion about everything but at the same time they are too lazy and dumb to actually understand what's going on. So media step in to fill that gap.
Utterly objective truth is a nice ideal but the human mind isn't equipped to contain it. It's more like a very elaborate club, evolved to fulfill self-interest.
What you can do is to look at multiple sources having separate/opposing agendas and only take those things they all say in common. The problem is that leaves you with very little information and the need to draw the lines and conclusions on your own. Which again means that your mind will let you see what it *wants* you to see.. but I guess that is still better than only seeing what some shady news corporation wants you to see.
