I was taught to aggressively look for and cut irrelevant facts. Back in the day newspapers and other printed material had space limitations. If your story didn't fit in the allotted column inches, the copy desk would cut it.
I also worked on a copy desk in college. Ideally a story has the most important information up front, in the inverted pyramid style, so that if an editor has to cut it for space, they can just cut from the bottom and not lose the main story. Given the very limited time the copy desk has to look at all the stories before deadline, writers than failed to lead with the key facts would know very quickly that they needed to work on their stories more.
