Unless you're looking for the science behind cognition and opinion itself, I doubt there's one objectively correct answer to this. I think it's because people come from different walks of life. And, depending on what you grew up around, facts can seem different purely because of your perspective. Two people looking at a square can perceive it differently depending on their angle. One may look at it head on and say "This is a square." The other may view it at an angle and say "This is a rhombus." Because, from their perspective, it is. Neither is incorrect in their own mind. People may have warped perceptions of what's around them, too. Somebody whose mind has been altered by trauma, perhaps, may view everything differently than somebody else. It's all a matter of perspective. I really hope this helps :)

The world might feel dying when you read news because that's what news are made for. For readers. And readers tend to catch on spicy ideas. Good things happen too, just no one is interested in them. I don't really understand the first part of your scroll tho. Why can't people even agree on facts? Because everything is true in our own heads. No one likes to break what they thought was right.
