Like other sciences, Political Science consists of subfields with, at times, different focuses, methodological approaches, and understandings of what constitutes “scholarly research of exceptional merit” that is worth being published in the American Political Science Review (APSR). In these Notes from the Editors, we want to take a closer look at subfield developments over time and provide some insights into the role of subfield classification in our editorial process. Being a cornerstone of this journal, we work hard as editors to publish a balanced selection of research from these subfields, which should theoretically mirror the submission rates we receive. Yet, despite having their own standards and principles for the evaluation of excellent manuscripts, subfield classifications often overlap in practice and change over time. Before we go into detail, we would therefore like to stress that the comparison of subfield developments, such as the number of submissions and acceptances, should always be taken with a grain of salt as their classification is neither exclusive nor complete.
