Technology is at the center of concern about political polarization around the globe. Yet most social scientists lack the technical training necessary to analyze the voluminous data generated on social media and other digital environments each day. Scholars in the computer sciences and engineering possess the skills to process these data, but struggle to translate them into systematic theories of polarization or other human behaviors. This grant will support the creation of eleven two-week workshops that would provide free training to at least 120 junior scholars within the nascent field of computational social science and incubate research across disciplinary lines. These sites would expand upon a pre-existing program, the Summer Institutes in Computational Social Science, by focusing upon theoretical and methodological issues specific to the study of polarization and inter-group conflict.
