Politics is the set of activities that are associated with making decisions in groups, or other forms of power relations among individuals, such as the distribution of resources or status. The branch of social science that studies politics and government is referred to as political science.
In the United States, politics functions within a framework of a constitutional federal republic and presidential system, with three distinct branches that share powers: the U.S. Congress which forms the legislative branch, a bicameral legislative body comprising the House of Representatives and the Senate; the executive branch, which is headed by the president of the United States, who serves as the country's head of state and government; and the judicial branch, composed of the Supreme Court and lower federal courts, and which exercises judicial power.
Neorealism or structural realism is a theory of international relations that emphasizes the role of power politics in international relations, sees competition and conflict as enduring features and sees limited potential for cooperation. The anarchic state of the international system means that states cannot be certain of other states' intentions and their security, thus prompting them to engage in power politics.
Political sociology is an interdisciplinary field of study concerned with exploring how governance and society interact and influence one another at the micro to macro levels of analysis. Interested in the social causes and consequences of how power is distributed and changes throughout and amongst societies, political sociology's focus ranges across individual families to the state as sites of social and political conflict and power contestation.
Democratization, or democratisation, is the structural government transition from an authoritarian government to a more democratic political regime, including substantive political changes moving in a democratic direction.
The tyranny of the majority is an inherent weakness to majority rule in which the majority of an electorate pursues exclusively its own objectives at the expense of those of the minority factions. This results in oppression of minority groups comparable to that of a tyrant or despot, argued John Stuart Mill in his 1859 book On Liberty.
Proponents of democratic peace theory argue that both electoral and republican forms of democracy are hesitant to engage in armed conflict with other identified democracies. Different advocates of this theory suggest that several factors are responsible for motivating peace between democratic states. Individual theorists maintain "monadic" forms of this theory ; "dyadic" forms of this theory ; and "systemic" forms of this theory.
In political science, voter turnout is the participation rate of a given election. This is typically either the percentage of registered voters, eligible voters, or all voting-age people. According to Stanford University political scientists Adam Bonica and Michael McFaul, there is a consensus among political scientists that "democracies perform better when more people vote."
Robert Alan Dahl was an American political theorist and Sterling Professor of Political Science at Yale University.
In political science, the term polyarchy was used by Robert A. Dahl to describe a form of government in which power is invested in multiple people. It takes the form of neither a dictatorship nor a democracy. This form of government was first implemented in the United States and France and gradually adopted by other countries. Polyarchy is different from democracy, according to Dahl, because the fundamental democratic principle is "the continuing responsiveness of the government to the preferences of its citizens, considered as political equals" with unimpaired opportunities. A polyarchy is a form of government that has certain procedures that are necessary conditions for following the democratic principle.
In political philosophy, the phrase consent of the governed refers to the idea that a government's legitimacy and moral right to use state power is justified and lawful only when consented to by the people or society over which that political power is exercised. This theory of consent is historically contrasted to the divine right of kings and had often been invoked against the legitimacy of colonialism. Article 21 of the United Nations' 1948 Universal Declaration of Human Rights states that "The will of the people shall be the basis of the authority of government". Consensus democracy is the application of consensus decision-making and supermajority to democracy.
Political egalitarianism describes an inclusive and fair allocation of political power or influence, fair processes, and fair treatment of all regardless of characteristics like race, religion, wealth or intelligence. Political egalitarianism, and its close cousin political equality, are key founding principles and sources of legitimacy for many democracies. Related principles include one person, one vote and equality before the law.
Noocracy is an ideal type of government where decisions are delegated to those deemed wisest. The idea is classically advanced, among others, by Plato, al-Farabi and Confucius.
Liberal democracy, Western-style democracy, or substantive democracy is a form of government that combines the organization of a representative democracy with ideas of liberal political philosophy.
Criticism of democracy, or debate on democracy and the different aspects of how to implement democracy best have been widely discussed. There are both internal critics and external ones who reject the values promoted by constitutional democracy.
The altruism theory of voting is a model of voter behavior which states that if citizens in a democracy have "social" preferences for the welfare of others, the extremely low probability of a single vote determining an election will be outweighed by the large cumulative benefits society will receive from the voter's preferred policy being enacted, such that it is rational for an “altruistic” citizen, who receives utility from helping others, to vote. Altruistic voting has been compared to purchasing a lottery ticket, in which the probability of winning is extremely low but the payoff is large enough that the expected benefit outweighs the cost.
Embedded democracy is a form of government in which democratic governance is secured by democratic partial regimes. The term "embedded democracy" was coined by political scientists Wolfgang Merkel, Hans-Jürgen Puhle, and Aurel Croissant, who identified "five interdependent partial regimes" necessary for an embedded democracy: electoral regime, political participation, civil rights, horizontal accountability, and the power of the elected representatives to govern. The five internal regimes work together to check the power of the government, while external regimes also help to secure and stabilize embedded democracies. Together, all the regimes ensure that an embedded democracy is guided by the three fundamental principles of freedom, equality, and control.
Bureaucratic drift in American political science is a theory that seeks to explain the tendency for bureaucratic agencies to create policy that deviates from the original mandate. The difference between a bureaucracy's enactment of a law and the legislature's intent is called bureaucratic drift. Legislation is produced by elected officials, but is implemented by unelected bureaucrats, who sometimes act under their own preferences or interests. Bureaucratic drift is often treated as a principal–agent problem, with the House, Senate and Presidency acting as principals and bureaucracy acting as the agent. The government seeks to control bureaucratic drift in a number of ways, most notably congressional oversight and procedural controls.
In political science, delegative democracy is a mode of governance close to Caesarism, Bonapartism or caudillismo with a strong leader in a newly created otherwise democratic government. The concept arose from Argentinian political scientist Guillermo O'Donnell, who notes that representative democracy as it exists is usually linked solely to highly developed capitalist countries. However, newly installed democracies do not seem to be on a path of becoming fully representative democracies. O'Donnell calls the former delegative democracies, for they are not fully consolidated democracies but may be enduring.
Rational choice is a prominent framework in international relations scholarship. Rational choice is not a substantive theory of international politics, but rather a methodological approach that focuses on certain types of social explanation for phenomena. In that sense, it is similar to constructivism, and differs from liberalism and realism, which are substantive theories of world politics. Rationalist analyses have been used to substantiate realist theories, as well as liberal theories of international relations.
