" The results of five experiments involving more than a thousand participants showed that reading literary fiction improves our ability to detect and understand other people's emotions. But it can't be any sort of fiction. The researchers distinguished between "popular fiction" (where the author leads you by the hand as a reader) and "literary fiction" (in which you must find your own way and fill in the gaps). Instead of being told why a certain character behaves as they do, you have to figure it out yourself. That way, the book becomes not just a simulation of a social experience, it is a social experience. "
