Neorealism or structural realism is a theory of international relations that says power is the most important factor in international relations. It was first outlined by Kenneth Waltz in his 1979 book Theory of International Politics. Alongside neoliberalism, neorealism is one of the two most influential contemporary approaches to international relations; the two perspectives have dominated international relations theory for the last three decades. Neorealism emerged from the North American discipline of political science, and reformulates the classical realist tradition of E. H. Carr, Hans Morgenthau, and Reinhold Niebuhr.
An ethnic conflict is a conflict between two or more contending ethnic groups. While the source of the conflict may be political, social, economic or religious, the individuals in conflict must expressly fight for their ethnic group's position within society. This final criterion differentiates ethnic conflict from other forms of struggle.
International relations (IR) or international affairs (IA)—commonly also referred to as international studies (IS), global studies (GS), or global affairs (GA)—is the study in interconnectedness of politics, economics and law on a global level. Depending on the academic institution, it is either a field of political science, an interdisciplinary academic field similar to global studies, or an entirely independent academic discipline in which students take a variety of internationally focused courses in social science and humanities disciplines. In all cases, the field studies relationships between political entities (polities) such as sovereign states, inter-governmental organizations (IGOs), international non-governmental organizations (INGOs), other non-governmental organizations (NGOs), and multinational corporations (MNCs), and the wider world-systems produced by this interaction. International relations is an academic and a public policy field, and so can be positive and normative, because it analyses and formulates the foreign policy of a given state.
International relations theory is the study of international relations (IR) from a theoretical perspective. It attempts to provide a conceptual framework upon which international relations can be analyzed. Ole Holsti describes international relations theories as acting like pairs of coloured sunglasses that allow the wearer to see only salient events relevant to the theory; e.g., an adherent of realism may completely disregard an event that a constructivist might pounce upon as crucial, and vice versa. The three most prominent theories are realism, liberalism and constructivism. Sometimes, institutionalism proposed and developed by Keohane and Nye is discussed as a paradigm differed from liberalism.
Constructivism is a view in the philosophy of science which maintains that scientific knowledge is constructed by the scientific community, who seek to measure and construct models of the natural world. According to the constructivist, natural science therefore consists of mental constructs that aim to explain sensory experience and measurements.
The security dilemma, also referred to as the spiral model, is a term used in international relations and refers to a situation in which, under anarchy, actions by a state intended to heighten its security, such as increasing its military strength, committing to use weapons or making alliances, can lead other states to respond with similar measures, producing increased tensions that create conflict, even when no side really desires it.
Alexander Wendt is an American political scientist who is one of the core social constructivist researchers in the field of international relations, and a key contributor to quantum social science. Wendt and academics such as Nicholas Onuf, Peter J. Katzenstein, Emanuel Adler, Michael Barnett, Kathryn Sikkink, John Ruggie, Martha Finnemore, and others have, within a relatively short period, established constructivism as one of the major schools of thought in the field. A 2006 survey of US and Canadian International Relations scholars ranks Wendt as first among scholars who have "been doing the most interesting work in international relations in recent years. A 2011 survey of international relations scholars worldwide ranked Wendt first in terms of having "produced the best work in the field of IR in the past 20 years".
Regime theory is a theory within international relations derived from the liberal tradition that argues that international institutions or regimes affect the behavior of states or other international actors. It assumes that cooperation is possible in the anarchic system of states, as regimes are, by definition, instances of international cooperation.
Realism is one of the dominant schools of thought in international relations theory, theoretically formalising the Realpolitik statesmanship of early modern Europe. Although a highly diverse body of thought, it is unified by the belief that world politics is always and necessarily a field of conflict among actors pursuing power. The theories of realism are contrasted by the cooperative ideals of liberalism.
Reflectivism is a broad umbrella label, used primarily in International Relations theory, for a range of theoretical approaches which oppose rational-choice accounts of social phenomena and, perhaps, positivism more generally. The label was popularised by Robert Keohane in his presidential address to the International Studies Association in 1988. The address was entitled "International Institutions: Two Approaches", and contrasted two broad approaches to the study of international institutions. One was "rationalism", the other what Keohane referred to as "reflectivism". Rationalists — including realists, neo-realists, liberals, neo-liberals, and scholars using game-theoretic or expected-utility models — are theorists who adopt the broad theoretical and ontological commitments of rational-choice theory.
Collective identity is the shared sense of belonging to a group.
In international relations, constructivism is the claim that significant aspects of international relations are historically and socially constructed, rather than inevitable consequences of human nature or other essential characteristics of world politics.
In international relations theory, anarchy is the idea that the world lacks any supreme authority or sovereign. In an anarchic state, there is no hierarchically superior, coercive power that can resolve disputes, enforce law, or order the system of international politics. In international relations, anarchy is widely accepted as the starting point for international relations theory.
The English School of international relations theory maintains that there is a 'society of states' at the international level, despite the condition of anarchy. The English school stands for the conviction that ideas, rather than simply material capabilities, shape the conduct of international politics, and therefore deserve analysis and critique. In this sense it is similar to constructivism, though the English School has its roots more in world history, international law and political theory, and is more open to normative approaches than is generally the case with constructivism.
Nicholas Onuf is an American scholar. Onuf is currently Professor Emeritus of International Relations at Florida International University and is on the editorial boards of International Political Sociology, Cooperation and Conflict, and Contexto Internacional. He is one of the primary figures among constructivists in international relations.
Feminist constructivism is an international relations theory which builds upon the theory of constructivism. Feminist constructivism focuses upon the study of how ideas about gender influence global politics. It is the communication between two postcolonial theories; feminism and constructivism, and how they both share similar key ideas in creating gender equality globally.
Social Theory of International Politics is an academic book by Alexander Wendt. It expresses a constructivist approach to the study of international relations and is one of the leading texts within the constructivist approach to international relations scholarship.
Classical Realism is an international relations theory from the realist school of thought. Realism follows the assumptions that: states are the main actors in the international relations system, there is no supranational international authority, states act in their own self-interest and states want power for self-preservation. Classical realism can be differentiated from the other forms of realism since it places specific emphasis on human nature as the key factor in explaining state behavior and the causes of inter-state conflict. Classical realist theory adopts a pessimistic view of human nature and argues that humans are not inherently benevolent but instead they are self-interested and act out of fear or aggression. Furthermore, it emphasizes that this human nature is reflected by states in international politics due to international anarchy.
The rationalist–constructivist debate is an ontological debate within international relations theory between rationalism and constructivism. In a 1998 article, Christian Reus-Smit and Richard Price suggested that the rationalist–constructivist debate was, or was about to become, the most significant in the discipline of international relations theory. The debate can be seen as to be centered on preference formation, with rationalist theories characterising changes in terms of shifts in capabilities, whereas constructivists focus on preference formation.
Quantum social science is an emerging field of interdisciplinary research which draws parallels between quantum physics and the social sciences. Although there is no settled consensus on a single approach, a unifying theme is that, while the social sciences have long modelled themselves on mechanistic science, they can learn much from quantum ideas such as complementarity and entanglement. Some authors are motivated by quantum mind theories that the brain, and therefore human interactions, are literally based on quantum processes, while others are more interested in taking advantage of the quantum toolkit to simulate social behaviours which elude classical treatment. Quantum ideas have been particularly influential in psychology, but are starting to affect other areas such as international relations and diplomacy in what one 2018 paper called a "quantum turn in the social sciences".
