What are journalists looking to provide when it comes to a news story.
The story should be Topical, Relevent, Unusual, with a bit of Tension or conflict and, very importantly, it should have Human interest.
Now let's think about it...
...Unusual eh? ...mmm.
So if the story you read is going to be unusual that means...well it means the more good news you read the less usual good news is.
So...that means bad news is the norm.
Now that is depressing.
