Economics, Morson and Schapiro say, has three systematic biases: it ignores the role of culture, it ignores the fact that “to understand people one must tell stories about them,” and it constantly touches on ethical questions beyond its ken. Culture, stories, and ethics are things that can’t be reduced to equations, and economics accordingly has difficulty with them. Morson and Schapiro’s solution is to use the study of the humanities, and particularly of realist fiction, to broaden perspectives and to reintroduce to economics those three missing factors.
