Professor Duffy’s pragmatic analysis is a method for analyzing the contents of political texts. It applies the inferential techniques of linguistic pragmatics to recover implicit contents of such texts. These implicit contents serve as inputs to formal models of the practical reasoning of political actors. Professor Duffy and several former students have published pragmatic analyses of the US-Soviet INF negotiations, constitutional debates in Canada and Belgium, and Henry Kissinger's early diplomatic encounters with Mao Zedong and Zhou Enlai. Pragmatic analysis has also been extended to the analysis of the rules systems that constitute security regimes, such as the Cold War. With his work on political conflict, Professor Duffy has extended early work on conflict processes, showing how these interact with the incentives that leaders distribute to constituents in efforts to mobilize conflict participation. In turn, this work shows how these mobilization efforts later hamstring leaders' efforts to settle conflicts. Professor Duffy is now engaged in research to tie these insights to political opportunity structures, or the regime-systemic constraints that encourage contending groups to adopt peaceable or violent means to settle disputes.
