He studies the science of how people behave. Kidd works at the New School for Social Research in New York. In 2012, he helped show that reading increases empathy. In a test, he made people read different kinds of books. Some of these books were literary fiction, or complex invented stories. These stories made people think about the emotions of the characters in them. After reading these literary fiction books, the people were better able to understand what other people were thinking. And they could more easily identify emotions.
