Conflict data sets can shed light on how different ways of measuring conflict (or any other international relations phenomenon) result in different conclusions. Data collection procedures affect our efforts to answer key descriptive questions about war and peace in the world and their relationship to other features of interest. Moreover, empirical data or information can answer some pointed questions about world politics, such as, “Has there been a decline in conflict in the international system?” The development of data on characteristics relevant to the study of international relations has undeniably allowed a great deal of progress to be made on many research questions. However, trying to answer seemingly simple descriptive questions about international relations often shows how data rarely speak entirely for themselves. The specific ways in which we pose questions or try to reach answers will often influence our conclusions. Likewise, the specific manner in which the data have been collected will often have implications for our inferences. In turn, proposed answers to descriptive questions are often contested by other researchers. Many empirical debates in the study of international relations, upon closer inspection, often hinge on assumptions and criteria that are not made fully explicit in studies based on empirical data.

The International Studies Association’s (ISA) Scientific Study of International Processes (SSIP) section is dedicated to the systematic analysis of empirical data covering the entire range of international political questions. Drawing on the canons of scientific inquiry, SSIP seeks to support and promote replicable research in terms of the clarity of a theoretical argument and/or the testing of hypotheses. Journals that have been most likely to publish SSIP-related research include the top three general journals in the field of political science: the American Political Science Review, American Journal of Political Science, and Journal of Politics. A number of more specialized journals frequently publish research of interest to the SSIP community, such as Conflict Management and Peace Science, International Interactions, International Organization, International Studies Quarterly, Journal of Conflict Resolution, and Journal of Peace Research. Together, these journals published a total of 1,024 qualifying articles between 2003 and 2010. These articles cover a wide range of topics, from armed conflict and conflict management to terrorism, international political economy, economic development or growth, monetary policy, foreign aid, sanctions, human rights and repression, international law, international organizations/institutions, and foreign policy attitudes and beliefs. Data users who are interested in conducting their own research must: choose the most appropriate data set(s), become familiar with what the data set includes and how its central concepts are measured, multipurpose data sources, investigate missing data, and assess robustness across multiple data sets.
