Political science is the social science that systematically studies politics, government, and power dynamics. It analyzes how power is distributed, decisions are made, and policies are implemented within and across countries. The field covers various aspects such as political behavior, political institutions, public policies, political thought, and the interactions between governments and citizens. Political science dates back about 2,500 years to philosophers like Plato and Aristotle, who defined it as the study of the state and its role in promoting the common good. Today, it is broadly divided into sub-disciplines including American government, comparative politics, international relations, and political theory. Political scientists use empirical and scientific methods to examine political systems and behaviors. Their work involves analyzing policies, predicting political trends, studying election results, and understanding political culture. The field bridges normative questions about justice and freedom with empirical observations and analysis, making it both prescriptive and descriptive. In summary, political science is the scientific study of power dynamics and governance in society, aimed at understanding and improving political institutions and practices. It is interdisciplinary and has practical applications in government, law, public policy, media, and beyond. This broad understanding aligns with definitions from academic sources such as universities, associations, and encyclopedias.
