The study of foreign policy decision-making seeks to understand how states formulate and enact foreign policy. It views foreign policy as a series of decisions made by particular actors using specific decision-making processes. The origins of this focus on decision-making are generally traced to the 1950s and 1960s, with the literature increasing in complexity and diversity of approaches in more recent decades. Foreign policy decision-making is situated within foreign policy analysis (a subfield of international relations subfield), which applies theories and methods from an array of disciplines—political science, public administration, economics, psychology, sociology—to understand how states make foreign policy, and how these policies translate into geopolitical outcomes. The literature on foreign policy decision-making is often subdivided based on assumptions about the process by which actors make foreign policy decisions—primarily falling into rational and nonrational decision-making; about who is assumed to make the decision—states, individuals, groups, or organizations; and about the influences believed to be most important in affecting those decisions—international factors, domestic political factors, interpersonal dynamics, etc. While much of the literature focuses on foreign policy decision-making in the United States, there have been attempts to apply models developed in the US context to other states, as well as to generate generalizable theories about foreign policy decision-making that apply to certain types of states.
