Strikingly, therefore, behavioral dispositions that enhanced success in the small-scale intergroup anarchy of humans evolutionary past may have endowed us with behaviors that also enhance success in the anarchy of the international system.

Conflict may seem costly to all parties involved, winners and losers alike, but what matters for natural selection is whether fighting, despite its costs, can bring net benefits to Darwinian fitness. Finally, evolution may make significant contributions to other theories of international relations. The Yanomamo among whom I lived were constantly worried about attacks from their neighbors and constantly lived in fear of this possibility. In addition to fighting over resources, we can now fight over ideology as well. Offensive realism holds that states are disposed to competition and conflict because they are self-interested, power maximizing, and fearful of other states. However, there is, of course, considerable variation in egoism, dominance, and ingroup/outgroup bias. Dominic Johnson is professor of international relations at the University of Oxford. Theorists have had to explain how cooperation could occur in the face of significant individual self-interest, the difficulties of collective-action, and the free-rider problem.Reference Boyd175,Reference Olson176,Reference Ostrom177 Special conditions are needed for cooperation to emerge and remain stable among unrelated individuals.178,Reference Sigmund179 Typically, those special conditions are ones that make helping advantageous to the genes responsible for the behavior. The Stratford scenes play out before a large, A-shaped wooden structure that represents Shakespeare's childhood home. The particular socio-ecological setting in which humans evolved meant that egoism, dominance, and groupishness were important behavioral adaptations, irrespective of the traits found in related species. The theory of Mearsheimer has five basis assumptions: 1. Utah's Office of Licensing, which provides oversight to youth residential treatment centers, has conducted 341 investigations in the past five years at Provo Canyon School's four campuses. 2018. 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. The fact that the five assumptions are instrumental to the theory of Mearsheimer is undeniable. Wilson captures the evolutionary logic succinctly, saying that humans would fight wars when they and their closest relatives stand to gain long-term reproductive success, and he continues, despite appearances to the contrary, warfare may be just one example of the rule that cultural practices are generally adaptive in a Darwinian sense.Reference Wilson73 An evolutionary approach allows the expectation that contemporary humans possess specific behavioral traits that contributed to fitness in the past, including the willingness to fight to retain or gain the resources necessary so that the individual, the family, and the extended family group would continue to survive and reproduce.Reference Lopez74, Unsurprisingly, direct evidence of human behavior from the Pleistocene era is rare, but in addition to archeological finds, we have evidence from recent and contemporary indigenous societies that offer a model for the behavior of our distant ancestors, who lived under similar social and ecological conditions. In short, our theory is one of behavioral ecologyhuman and animal behaviors are not constants, but are contingent strategies that become engaged or elevated in order to best seek payoffs depending on the particular circumstance or environment. realism's 5 assumptions about the international system o 1)the international system is anarchic (no higher ruling body) o 2) states inherently possess some offensive military capability which gives them the wherewithal to hurt and possibly to destroy each other o 3) states can never be certain about the intentions of other states 17 This is why he considers the US a regional hegemon, not a global one. As we would expect, this leads to sex differences in the desire for status. Furthermore, cooperation is often itself a means to power maximization in the formation of military and security alliancesand thus, cooperation can be a prediction of, not a challenge to, offensive realism. First, offensive realism fails to explain why costly wars sometimes occur against the interests of the states that initiate them. Our evolutionary theory of offensive realism is unlimited in time, explaining behavior from the ancestral environment to the present day, whereas offensive realism is conventionally inapplicable prior to 1648, when the Treaty of Westphalia established the European state system. The core idea of offensive realism is that a state most reliably ensures its security by maximizing its power. 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. It is not just that we lack a global Leviathan today; humans never had such a luxury. A comparison among alternative realist theories. It is important to appreciate, however, that some influences on human evolution have extended over a much longer timescale. Males of most mammal species are particularly competitive with each other over females. The very existence of these phenomena, not to mention the extreme efforts and expense they continually require to function, only supports the point that international politics needs very special and powerful arrangements to prevent people from acting as offensive realistspredisposed as they are to do so. But what was that context? Humans may pursue self-interest and power by many means, including, for example, patience and reciprocity as well as coercion and violence. These types of adaptations not only consume precious time and energy but can also decrease survival in other, nonreproductive domains of life (for example, the plumage of male peacocks limits their ability to fly). In fact, he was highly critical of the Iraq War (200311) and what he saw as an attempt by the United States to police the world. 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. The recent crises of the Euro and migration have shown in stark terms that individual states continue to exploit the opportunity to free-ride on others if they can, and even the most powerful states, such as Germany, France, and the United Kingdom, have been reluctant or unwilling to make sacrifices to protect other states. The fundamental differences and similarities between our theory of offensive realism and Mearsheimers arecaptured in Table4. Neorealism points to international anarchy, a phenomenon we can evaluate, as the ultimate cause of state behavior. The second contribution of our theory is that it offers an explanation of the behavior of humans in a wide variety of contexts extending beyond international politics. Second, we introduce key evolutionary concepts that explicate the human behaviors upon which offensive realism depends. An individuals Darwinian fitness therefore includes the success of related others (hence the phrase inclusive fitness). 2022. 4 (December 1997), pp. He received a masters degree (1974) in international relations from the University of Southern California, as well as a masters degree (1978) and a Ph.D. (1981) in government from Cornell University. What is the logic for risking life and limb in engaging in violent aggression against other groups? Individuals bide their time, form coalitions and alliances, and cooperate with others, but they also seize power where the opportunity arises. Table1. Psychologists argue that the ingroup/outgroup distinction develops from a need for social identity. Huda, Mirza Sadaqat Behavior under anarchy in different domains. Hunter gatherers have recurrent tendencies, including hostility toward members of different societies, and for killing to be carried out in relative safetythat is, only when there is a strong asymmetry in power between subgroups, such as in a raid or ambush (the imbalance of power hypothesis). We are also yet to see how European states will cooperate or compete when the U.S. security umbrella is removed. "Mearsheimer's WorldOffensive Realism and the Struggle for Security: A Review Essay" International Security 27:1 (2002): 149-174; Offensive Realism and Maximizing Power. According to Waltz, the need for security leads states to favour the status quo and to adopt a defensive position toward their competitors. In this article, Where these conditions are tempered, such as in the modern peaceful democracies of Western Europe, these cognitive and physiological mechanisms are likely to be more subdued. Hamilton used genetic models to show that, while individual organisms are egoistic, they should be less so in their behavior toward genetic relatives, especially in parent-offspring and sibling relationships.Reference Hamilton87,Reference Hamilton88 This decrease in egoism is because close relatives share many of the same genesone-half for siblings and parents, one-quarter for aunts, uncles, and grandparents, and one-eighth for cousins. Therefore, even the strongest advocates of group selection, such as David Sloan Wilson, argue that, in any given case, it remains an empirical question as to whether or not the selection pressures acting at the level of individuals are outweighed by selection pressures potentially acting at the level of the group (so called multi-level selection). Note that the table captures key patterns, not universal behavior. As we have noted, offensive realism contains explicit assumptions about how states behave in international politicsgiven the hostile environment, states are (and ought to be if they are to survive) self-interested, power maximizing, and fearful of others. In 2003 he was elected to the American Academy of Arts and Sciences. The brain may be responding exactly as it was designed to do, given informational inputs from the environment. Some of these date from the split with our last nonhuman primate ancestor at the beginning of the Pliocene, around 5 million years ago. The most obvious challenge that evolutionary theory presents to international relations concerns our understanding of human nature. Will the outsider be a threat to oneself or to ones family? However, another important source of variation is individual differencesthat is, specific people exhibit these traits to greater or lesser degrees. First, we explain the theory of offensive realism and the place of anarchy in that theory. Mearsheimer outlines five "bedrock" assumptions on which offensive realism stands: (1) the international system is anarchic; (2) great powers inherently possess some offensive military capability; (3) states can never be certain about the intentions of other states; (4) survival is the primary goal of great powers; and (5) great powers are We use cookies to distinguish you from other users and to provide you with a better experience on our websites.

Identification with a specific group provides individuals with meaning and purpose, encouraging them to become part of a community with common interests, values, and goals.Reference Hewstone, Rubin and Willis122,Reference Fiske123,Reference Sidanius and Pratto124 One also knows what one is notthe outgroup, which is stereotyped and homogenized as the Other. Among the many different possible ingroup categories, the most common and significant include family, friends, age, sex, class, ethnicity, politics, religion, and nationality. The anarchic state of the international system means that states cannot be certain of other states' intentions and their security, thus prompting them to . Correspondence: Dominic D. P.
