The 200 Happiest Words in Literature

There are six main types of stories in fiction. That’s what computer scientists found after teaching a machine to map the emotional arc of a huge corpus of literature. The overall research they did is fascinating (I wrote about it in greater detail here), but several smaller components of the work are compelling in their own right.
