In journalism, there’s what you call your dog-bites-man situation. Which is anything too common and expected to be a good story (unless the dog is one of those Resident Evil hellhounds, or the man is Cesar Millan). An example of a dog-bites-man science story is yet another confirmation of Einstein and relativity.
Then there’s your more compelling man-bites-dog scenario. Which is something out of the ordinary (unless the man is competitive eater Takeru Kobayashi, and the dog is a Nathan’s Famous with mustard and sauerkraut). An example of a man-bites-dog science story is the recent claim of neutrinos that move faster than light. Although this particular case might be more accurately called a man-claims-to-bite-dog-but-physicists-really-wanna-get-a-close-look-at-this-dog story.
