Oracles of Peace: Topic Modeling, Cultural Opportunity, and the Nobel Peace Prize, 1902–2012^*

Social movement frames are dynamic, shifting and embedded within an already existent cultural milieu—a milieu that affects mobilization opportunities. In this article, we invoke the concept of the “cultural clearinghouse” to tackle how broader cultural structures translate to frames or influence frame resonance. Our illustrative case, the Nobel Peace Prize, along with our use of topic modeling, a computational technique that identifies commonalities between texts, offer an important methodological advance for social movement scholars interested in culture, frame formation and resonance, and dynamic approaches to social movement discourse. Our findings show how peace discourse—as represented by Peace Prize acceptance speeches—increasingly has become embedded within broader cultural emphases on globalization and neoliberalism, versus earlier Christian and global institutional schemas. We conclude by discussing the usefulness of our conceptual and methodological advance for movement scholars with special attention to the coupling of new computational techniques and more traditional methods.
