I'm not sure. Are we talking about stories where the author is a genius, or where one of the characters is a genius? For example, the film "A Beautiful Mind" is about character who's clearly a genius, but I don't recall the script showing signs of its writer having rare intelligence. Whereas stories like Deathnote have some plot twists that make me think the author is highly intelligent, regardless of the IQ of most of the characters. I'm guessing I'd put a story into this category if there were plot revelations at the end which in retrospect I could have figured out my self, but didn't until the moment chosen by the author.
