Huh? Who determines which facts are important to a story? It’s turtles all the way down.
Fact A) Carrots are healthy. Fact B) Carrots may be carcinogenic.
These are both inherently important facts to any story talking about the health, or danger, of carrots. To present a position on if one should be eating carrots or not, without including both of these facts, is to handpick facts to tell the story you want to tell.
