Narrative policy analysis provides a way of analyzing those highly uncertain and complex policy issues whose truth-value cannot be ascertained and about which the only thing practicing policy analysts know are the stories policymakers use in articulating these issues. One extremely well-documented controversy, the 1980-82 California Medfly Crisis, illustrates how a comparison and analysis of the structure of the dominant stories in that controversy reduces some of its underlying uncertainty. By focusing on the differential risk perceptions reflected in the stories, narrative policy analysis identifies an important area in which conventional policy analysis could have contributed to the controversy's resolution.
