Authors may choose to write about characters with extreme personalities, or characters who have a skill that they have mastered because it makes the story more intense, and more interesting for the reader. A character with an ability to reconise any musical piece, maybe without even hearing it before, would be an example. Similarly, a character like Sherlock Holmes can figure out any piece of information just by stepping back and looking at the details of a crime. Although his knowlege may be based on information, Sherlock Holmes can connect the clues and infer what could have happened at a crime scene. This is one of the true characteristics of a wise character, because even Albert Einstein said that "information is not knowlege."
