“While an author can write about characters more sophisticated than himself, it is difficult to fashion a character who is more knowledgeable and intelligent than the author, particularly if the author is going into the character’s most profound thoughts. That’s why characters like scientists, public figures, and intellectuals in some popular novels come across as stilted or fake. Similarly, if the author is writing about people less intelligent than himself, he must be careful not to put thoughts into a character’s head that are beyond that character’s capabilities.”
