Modern political science can generally be divided into the three subdisciplines of comparative politics, international relations, and political theory. Other notable subdisciplines are public policy and administration, domestic politics and government (often studied within comparative politics), political economy, and political methodology. Furthermore, political science is related to, and draws upon, the fields of economics, law, sociology, history, philosophy, human geography, journalism, political anthropology, psychology, and social policy.
Political science is methodologically diverse and appropriates many methods originating in psychology, social research, and cognitive neuroscience. Approaches include positivism, interpretivism, rational choice theory, behaviouralism, structuralism, post-structuralism, realism, institutionalism, and pluralism. 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the social sciences, uses methods and techniques that relate to the kinds of inquiries sought: primary sources, such as historical documents and official records, secondary sources, such as scholarly journal articles, survey research, statistical analysis, case studies, experimental research, and model building.
