mearsheimer's 5 assumptions of realism

He received a D.Phil. Even where dominance hierarchies are actively suppressed, such as in more egalitarian small-scale societies, suppression itself is evidence of the competition for status that simmers beneath the surface.Reference Boehm99 In historical and contemporary societies, competition for power is all too obvious, and the quest for status, dominance, and leadership is ancient and ever present.Reference Mazur100,101,Reference Ludwig102,Reference King, Johnson and Van Vugt103. Hostname: page-component-75b8448494-spc8s [2] The five bed-rock assumptions of Mearsheimer's theory of offensive realism are: Why would hunter-gatherer groups fight at all? 1 (Summer 1990), pp. Between groups, group selection would do the opposite, maintaining or even exacerbating conflict.187 Because the premise is that selection operates at the level of groups, altruistic traits can only spread if altruism helps spread the genes responsible for it at the expense of other genes, and that must occur via intergroup competition or conflict. Under these conditions, such behavior will have been favored by natural selection and spread. Structuralism is a method of study that focuses on the interaction of the parts, or units of a system, seeing them as more useful to study than the individual units themselves.27 Waltz uses structuralism to demonstrate how the distribution of power in international politics is critical for understanding whether war is more or less likely.28 By wedding anarchy as an ultimate cause and structuralism as a method of analysis, Waltzs neorealism improves upon Morgenthaus realism in two ways. We thank Robert Jervis for bringing this point to our attention. We do not propose a nave transplant of nature red in tooth and claw (to quote Tennyson) into international politics. As we would expect, this leads to sex differences in the desire for status. Debate continues as to whether modern states actually do, or should, behave in this way, but we are struck by a different question. John Mearsheimers contribution to neorealism has also proved significant. The constraints on biological group selection, such as significant differences in a given trait between groups and low migration, are relaxed in the case of cultural traits, since groups actively promote cultural distinctions and have many mechanisms to prevent flows between them.Reference Richerson and Boyd190 Therefore, it is not just likely but quite apparent that many cultural traits have evolved out of group-level competitionsometimes referred to as memes, as opposed to genes. However, he criticized post-Cold War U.S. foreign policy for overestimating the countrys military power and its capacity to project that power at will. Instead, the best strategy is a constant effort to maximize power to stay ahead of rivals. Offensive realism, a theory of international relations, holds that states are disposed to competition and conflict because they are self-interested, power maximizing, and fearful of other states. Warfare might then be necessary for offensive purposes, to plunder resources from others. In fact, interactions with people from other groupsunrelated others that may not have shared interestsmay be especially costly or lethal compared to within-group interactions. 2018. First, to whatever extent anarchy deserves its place among realist presumptions, the evolution of human groups interacting in conditions of anarchy deserves study within realism. Nationalism and the Nation-State in Structural Realism: John Animals do not constantly fight. All three species descended from an (unknown) common ancestor. Mearsheimer, taking his geography argument further, asserts that stopping the power of w ater is precisely why no state can be a global hegemon. Waltzs core concept in Theory of International Politics is the anarchy that reigns in world politics. Humans survived (and note that several other Hominin species did not) by virtue of evolved behavioral traitsamong them egoism, dominance, and the ingroup/outgroup biaswhich were adaptations to competitive ecological conditions. Psychologists argue that the ingroup/outgroup distinction develops from a need for social identity. However, because anarchy is a problem both in nature and in international politics, it is no coincidence at all. For their exceptional advice and comments, we thank lafur Darri Bjrnsson, Dan Blumstein, Miriam Fendius Elman, John Friend, David Galbreath, Azar Gat, Matthew Gratias, Valerie Hudson, Patrick James, Robert Jervis, Robert Keohane, Charles Lees, Anthony Lopez, Curt Nichols, Rose McDermott, Steven Pinker, Michael Price, Stephen Peter Rosen, Rafe Sagarin, Dominic Tierney, Monica Toft, Peter Turchin, Mark Van Vugt, Richard Wrangham, Remco Zwetsloot, and the anonymous reviewers. Mearsheimer's theory is a spin-off of Kenneth Waltz's neorealism, also known as structural or defensive realism. For Mearsheimer, states seek to maximize power not because they are aggressive, but because the system requires itthis behavior is the best way to maximize security in an anarchic world. What made war inevitable was the growth of Athenian power and the fear which this caused in Sparta.. We argue that evolution under conditions of anarchy has predisposed human nature toward the behaviors predicted by offensive realism: Humans, particularly men, are strongly self-interested, often fear other groups, and seek more resources, more power, and more influence (as we explain in full later). For example, among wolves, lions, and chimpanzees, when members of rival groups are found alone, they are extremely vulnerable and risk being killed.140,141,142 We discussed intergroup killing in chimpanzees earlier, but the pattern is notable among social carnivores, too: Studies of undisturbed wolf populations in Alaska have found that 39 to 65 percent of adult deaths were due to intergroup killing.Reference Mech, Adams, Meier, Burch and Dale143, Of course, the ability to assess threats is much more complex in humans than it is in other animals, and human intelligence gives us a greater repertoire of behavior. | Find, read and cite all the research you . Indeed, a wide range of empirical evidence from psychology and neuroscience suggests instead that humans, especially men, not only want to be leaders but also enjoy the pursuit of power (as well as its material fruits).156,Reference Robertson157,158 The force of this motivation is frequently revealed in victors expressions of the satisfaction of conquest. Instead, we can make more concrete predictions about how humans tend to think and act in different conditions, based on new scientific knowledge about human cognition and behavior, and in particular a greater understanding of the social and ecological context in which human brains and behaviors evolved. The fact that all prior utopian visions have failed to come to fruition does not prove that current ones will fail too. Egoism and dominance arose as strategies that provided solutions to achieving survival and reproduction in this environment. As Chinggis Khan is purported to have said: The greatest happiness is to vanquish your enemy, to drive him before you, to see his cities reduced to ashes.159 Although not usually expressed in such stark terms, the pleasure of competition and victory has been widely recognized as a feature of human nature from classical times to the present day, and success in competitive interactions and the domination of others are known to increase testosterone and dopamine responses in menthe so-called victory effect.160 Such dominance behavior is, we suggest, exaggerated among leaders because they are generally ambitious and competitive, and usually male.

Mearsheimer follows on the premises of Kenneth Waltz's theory by deriving the behavior of states from the "structure" of the international system. The organism has to ensure that its physiological needs (for food, water, shelter, and so on) are satisfied so that it can survive and reproduce. Collective action to attain public goods, however, is much harder to attain because of the threat of free-riders (as demonstrated, for example, by the slow response to climate change, the reluctance of states to accept Syrian refugees, and Eurozone fiscal responsibility). These adaptations were favored by natural selection over the course of evolution and remain a significant cause of human behavior. Aggression is not a cultural accident, but an evolutionary adaptation for acquiring and securing resourcesjust as it is for other species. Third, the group could acquire more of the resource from outside of their territory through migration to uninhabited areas, trade, theft, or warfare.65,77,Reference Guilaine and Zammit67,Reference LeBlanc and Register68,Reference Wrangham and Peterson69,70, Although warfare is certainly costly to any member of a group who is killed or wounded, as well as in terms of the resources and time expended, it can become the sole (or least bad) choice for a group if migration is risky due to factors such as inhospitable or unproductive terrain or hostile neighboring groups, and where trade is difficult or impossible. As such, an evolutionary account does not necessarily expect animals, humans, or states to act as offensive realists all the time and in all situations. The international system is anarchic. Neorealism (international relations) - Wikipedia While every effort has been made to follow citation style rules, there may be some discrepancies. Any given individuals Darwinian fitness will be increased if they can successfully seize the resources of others at sufficiently low cost.Reference Buss and Shackelford71 Of course, warfare also may be waged for defensive reasons, such as to defend critical resources from the advances of others.72 E.O. As we have stressed, the human traits of egoism, dominance, and ingroup/outgroup bias are adaptations to the ecological conditions prevalent in human evolution. } The role of war in the evolution of political systems and the functional priority of defense,, For an excellent review of the logic for, and evidence of, adaptations for war, see, Inclusive fitness has recently been the subject of a heated debate in the biological literature; see M. A. Nowak, Corina E. Tarnita, and Edward O. Wilson, The evolution of eusociality,, There is copious evidence from historical and contemporary times that such nepotism is a significant influence in politics. Dominance behavior occurs in thousands of taxonomic groups ranging from fish and reptiles to birds and mammals. In fact, however, anarchy has been a constant feature of the entire multimillion year history of the human lineage (and indeed the 3.5 billionyear history of the evolution of all life on Earth before that). We recognize that offensive realism remains controversial, and we would like to address three fundamental problems with the theory. If our hypothesis is correct, then evolutionary theory offers the following: (1) a novel ultimate cause of offensive realist behavior; (2) an extension of offensive realism to any domain in which humans compete for power; and (3) an explanation for why individual leaders themselves, and not just states, seek power. However, we argue that offensive realists need not depend on the anarchy of the state system to advance their argument. Despite realisms long history as a theory of international politics and its widespread use by scholars and policymakers such as E.H. Carr, George Kennan, Henry Kissinger, and Hans Morgenthau, the traditional realist argument rests on weak foundations. Eric Labs captured this logic in his argument that, a strategy that seeks to maximize security through a maximum of relative power is the rational response to anarchy.38. Huda, Mirza Sadaqat By 2009, after 18 such killings, the rival group had been all but destroyed. A key debate in evolutionary anthropology has revolved around the origins and extent of intergroup conflict among hunter-gatherers, and the emerging consensus is that such conflict is (and has long been) significant and widespread, and that it serves adaptive functions.59, Let us first consider these functional advantages. This seemingly straightforward idea is controversial, not least among realists themselves. Evolutionary theory offers a powerful explanation for the trait of egoism (by which we mean the nonpejorative definition of self-regarding, prompted by self-interest).86 Given competition for limited resources and threats from predators and the environment, an individual organism is primed to seek its own survival andthe Darwinian bottom linereproductive success. Evolutionary theory accounts for egoism and explains why cooperation can extend to the family or close kin group but remains difficult between unrelated individuals. Analysing Mearsheimers Critique Of Structural Realism Politics Essay Although warfare is a high-stakes collective action problem, warriors are willing to participate because over evolutionary time the dividends have tended to outweigh the costs.84,Reference Wrangham and Glowacki85. By contrast, as rational actor theorists would expect, hunter-gatherers are averse to the risk of fighting symmetric battles with roughly equivalent numbers on each side.82 Importantly, sustained instances of imbalances of power over evolutionary history would have led to the selection of contingent aggression.
