Political science

Political science is an academic and research discipline that deals with the theory and practice of politics and the description and analysis of political systems and political behavior. Fields and subfields of political science include positive political economy, political theory and philosophy, civics and comparative politics, theory of direct democracy, apolitical governance, participatory direct democracy, national systems, cross-national political analysis, political development, international relations, foreign policy, international law, politics, public administration, administrative behavior, public law, judicial behavior, and public policy. Political science also studies power in international relations and the theory of Great powers and Superpowers.

Political science is methodologically diverse, although recent years have witnessed an upsurge in the use of the scientific method. That is the proliferation of formal-deductive model building and quantitative hypothesis testing. Approaches to the discipline include rational choice, classical political philosophy, interpretivism, structuralism, and behavioralism, realism, pluralism, and institutionalism. Political science, as one of the social sciences, uses methods and techniques that relate to the kinds of inquiries sought: primary sources such as historical documents, interviews, and official records, as well as secondary sources such as scholarly journal articles are used in building and testing theories. Empirical methods include survey research, statistical analysis/econometrics, case studies, experiments, and model building. Herbert Baxter Adams is credited with coining the phrase "political science" while teaching history at Johns Hopkins University.
