The SAGE Handbook of Research Methods in Political Science and International Relations offers a comprehensive overview of research processes in social science - from the ideation and design of research projects, through the construction of theoretical arguments, to conceptualization, measurement, and data collection, and quantitative and qualitative empirical analysis - exposited through 65 major new contributions from leading international methodologists. Each chapter surveys, builds upon, and extends the modern state of the art in its area. Following through its six-part organization, undergraduate and graduate students, researchers and practicing academics will be guided through the design, methods, and analysis of issues in Political Science and International Relations: Part One: Formulating Good Research Questions and Designing Good Research Projects; Part Two: Methods of Theoretical Argumentation; Part Three: Conceptualization and Measurement; Part Four: Large-Scale Data Collection and Representation Methods; Part Five: Quantitative-Empirical Methods; Part Six: Qualitative and Mixed Methods.
Chapter 37: Selection Bias in Political Science and International Relations Applications
Selection Bias in Political Science and International Relations Applications
Empirical scholars in international relations and, more generally, political science regularly face challenges stemming from selection bias, which arise when researchers are confronted with non-random samples. The study of the effectiveness of international institutions, for example, sees countries mainly joining those organizations whose obligations they find rather unproblematic to adhere to. This non-random self-selection, in turn, has probably severe consequences for how international institutions perform. Likewise, the decision to go to war oftentimes hinges on the same factors that afterwards determine their duration or outcome. Similar problems occur in almost any subfield of political science from the study of electoral behavior to the examination of protests, public opinion, political economy or environmental politics. ...
