As humanities majors slump to the lowest level in decades, calls are coming from surprising places for a revival. Nobel Prize winner Robert Shiller’s new book “Narrative Economics” opens with him reminiscing about an enlightening history class he took as an undergraduate at the University of Michigan. He wrote that what he learned about the Great Depression was far more useful in understanding the period of economic and financial turmoil than anything he learned in his economic courses. “Traditional economic approaches fail to examine the role of public beliefs in major economic events — that is, narrative,” Shiller wrote. Shiller isn’t alone in wishing that there were more storytellers (and story analyzers) around.
