In Race and the Making of American Political Science, Jessica Blatt argues that the professionalization of the discipline was deeply entwined with ideas about racial difference, and the concomitant attempt by leading scholars to define and defend a system of racial hierarchy in the United States and beyond. Although it focuses on the period from the late nineteenth century through the 1930s, the book also raises fundamental questions about the historical legacy of racialist arguments for professional political science, the extent of their continuing resonance, and contemporary implications for both academic and broader civic discourse. We have asked a range of leading political scientists to consider and respond to Professor Blatt’s important call for scholarly self-reflexivity.
