How diverse and inclusive are policy process theories?
Numerous published efforts have compared and contrasted policy process theories. Few assessments, however, have examined the extent to which they are inclusive or diverse. Here we summarise lessons from previous assessments, paying attention to how Paul Sabatier’s science-based criteria have shaped the contours of the field. In looking at these contours, we explore evidence of diversity and inclusivity of policy process approaches in terms of methods, concepts, topics, geography and authors. We conclude with strategies to address challenges revealed by our examination: creating space for conversations among scholars of differing perspectives and approaches; building sustained and meaningful efforts to recruit and train researchers with diverse backgrounds; establishing research coordination networks that focus on policy problems; and creating better metrics to assess our diversity and inclusivity.
