Worrying for the Wrong Reason

"Butch: Alright. I'll jump first. Sundance: No. Butch: Then you jump first. Sundance: No, I said. Butch: What's the matter with you?! Sundance: I can't swim! (Butch starts laughing hysterically.) Butch: Are you crazy?! The fall will probably kill you!"

- Butch Cassidy and the Sundance Kid

One character expresses some concern about a situation. Another character corrects them, telling them what they should really be worried about. Not to be confused with Skewed Priorities, which is about being disproportionately concerned over something comparatively trivial, or with It's All About Me, which is about putting one's own interests ahead of everyone else's. This trope is about a character who has a legitimate fear that is then replaced with another legitimate fear.

A subtrope of Right for the Wrong Reasons.

 * The film Willy Wonka and the Chocolate Factory has Augustus Gloop get stuck in a pipe. His panicky mother shrieks that he'll be "melted into marshmallows," to which Wonka responds that the very idea is patently absurd.

Literature

 * When the Animorphs find themselves on a cliff on the meteor-wrecked Hork-Bajir planet, they notice the planet's molten core far below them. One character worries about the possibility of falling into the magma. Ax says that this won't happen—if they fell, they'd be vaporized by the heat long before they reached it.
 * Making Money introduces the drink Splot, a sort of Klatchian Coffee Up to Eleven. People are often reassured when they hear Splot is nonalchoholic...until they're told it's because "alcohol wouldn't survive."
 * And in The Last Continent, there are very few poisonous snakes in XXXX... because most of them have been eaten by the spiders.
