Political science seeks to understand, to explain, and — sometimes — to evaluate how humans live and work together in public ways. To do so, political scientists focus on what happens in and around government and politics, how humans cooperate with and how they fight against one another, why some nations succeed and others fail.
Political scientists study voting and revolutions, the Supreme Court and the United Nations, the idea of justice and the nature of power, environmental policy, criminal law and gender politics - all in the pursuit of clearer knowledge about the characteristic ways humans interact in the public sphere.
