Cultural group selection plays an essential role in explaining human cooperation: A sketch of the evidence. In principle, altruism confounds the basic logic of evolution by natural selection because individuals incur fitness costs while providing benefits to others. There is however another explanation for the evolution of altruistic dispositions in humans, which does not face these problems and is supported by extensive evidence. The obvious challenge to genetic group selection accounts of the evolution of human altruism is that individual selection is a prominent driver of evolution. Groups of non-altruistson the other handeventually perished, so their members left no descendants. Between group dynamics selectamong other thingsfor prosocial norms and punishments. There is also good evidence that humans are endowed with an innate sense of fairness and a desire to act accordingly. Enquist, M., & Leimar, O. Liu X, Zhang Y, Chen Z, Xiang G, Miao H, Guo C. Int J Environ Res Public Health. Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. While they might do so for a variety of reasonsincluding virtue signalingmoral reasoning is likely to be an important factor. They typically do so because they empathize with these strangers and decide it is the morally right thing to do. Norm abidance is indeed a major cause of altruistic behavior (see Sect. The Evolution of Reciprocal Altruism. On the surface, it seems that the only cooperative relationship between a tourist and a host country is that of the economic agenda. Western people who donate funds to starving Africans know very well that they are doing so for the benefit of out-group individuals. Evolved psychological dispositions, however, do not suffice to explain many instances of actual human altruistic behavior. In D. M. Buss (Ed. 2007; Puurtinen and Mappes 2009). by sharing food) only makes sense when it is directed at genetically related organisms or when one can expect the favor to be returned. American Economic Review, 91, 7378. During this process, pollen is collected in the bodies of the bees at one flower and rubs off onto another, pollinating the flowers. Culture-gene coevolution, norm-psychology and the emergence of human prosociality. Encyclopedia of Evolutionary Psychological Science pp 26052606Cite as, Behavioral game theory; Cooperation; Evolutionary psychology; Reciprocity; Theory of mind, Evolution of reciprocal altruism studies the evolutionary basis of cooperation within evolutionary agents (here special focus on Homo sapiens). Jacobson, A. Human Nature, 10(3), 253289. Journal of Economic Perspectives, 9(2), 209219. This is close to the notion of "tit for tat" introduced by Anatol Rapoport,[4] although there still seems a slight distinction in that "tit for tat" cooperates in the first period and from thereon always replicates an opponent's previous action, whereas "reciprocal altruists" stop cooperation in the first instance of non-cooperation by an opponent and stay non-cooperative from thereon. When explaining altruistic human behavior (and norms) we must also take into account conscious and voluntary reasoning processes. It assumes that altruistic behavior is solely the result of evolved, hardwired psychological mechanisms adapted to the ancestral social environment. This creates three possible scenarios: If one cooperates and the other does not, then the former benefits greatly while the latter suffers. Lets be honest here. Evolution of Cooperation: Combining Kin Selection and Reciprocal - PLOS Cosmides, L., & Tooby, J. Warneken, F., & Tomasello, M. (2009). These explanations often invoke group selection. Such a position is not only championed by Sober and Wilson (1998), others followed in their wake (e.g. Sociobiologists have explained altruistic behavior by way of kinship theory and reciprocity theory. A whopping sixty percent of casual human conversations are about other people (Dunbar et al. While anthropological evidence for the universality of prosocial punishment is of course no guarantee that ancestral human (hunter-gatherer) societies would have possessed such prosocial punishments, it is nevertheless a good indication that they had. Altruism: Acting in such a way that incurs a cost from oneself and benefits another.1, Reciprocal Altruism: A behavioral strategy in which an agent sacrifices for the benefit of a recipient who is not closely related, where a return benefit to the agent may be reciprocated in the future.3, 4. In other words, participants often follow the social norms that govern the social interaction in their societies. Mathew, S., & Boyd, R. (2011). According to Binmore (2005), a universal deep structure of fairness underlies human fairness considerations, analogically to Chomskys (1955) deep structure underlying natural language acquisition (the so-called universal grammar). Cheater: Within the context of reciprocal altruism, a cheater is someone that is always on the receiving end of altruistic behaviors from others but never reciprocates. 2005). What Is Evolutionary Altruism? Understanding both cognitive and emotional building blocks is critical to the evolution of reciprocal altruism because the degree to which these building blocks are present can constrain what types of reciprocal altruism can evolve. [13] In these examples, true reciprocity is difficult to demonstrate since failure means the death of the cleaner. Regarding human reciprocal altruism, it is shown that the details of the psycho-logical system that regulates this altruism can be explained by the model. Prosocial norms and punishment in ancestral societies did not only ensure that free-riders did not get away with their cooperation eroding behavior (they are being punished) and that consequently altruism could be sustained within groups (Vlerick 2016, 2020a), over time they also shaped the genome of the individuals inhabiting those societies. The following examples could be understood as altruism. PNAS, 100(6), 35313535. When the famous biologist Edward Wilson (not to be confused with David Wilson mentioned above) wrote an article in which he defended genetic group selection with colleagues Nowak et al. Finally, individuals from less wealthy groups often migrate to wealthier groups and the customs and norms of successful groups are often imitated by less successful neighboring groups (Bowles and Gintis 2011, p. 50). 10), and with 5 or . So long as both participants start by picking the cooperative move (engaging in reciprocal altruism) and continue to do so, this cooperative behavior will remain present in the participants dynamic. Hosts leave their element to get cleaned. (2013). Bees, for example, fly from flower to flower to collect nectar which they use to make honey. Our moral psychology, as argued above, evolved as an adaptation to a highly cooperative niche characterized by strong prosocial norms and punishments that orchestrated in-group interaction. It is defended the claim that human altruistic dispositions evolved through cultural group selection and gene-culture coevolution and offered empirical evidence in support and it is argued that actual altruistic behavior often goes beyond the kind of behavior humans have evolved to display. Humans, however, often engage in altruistic acts directed at strangers (non-kin) and with no chance of reciprocation. The Evolutionary Biology of Altruism | Psychology Today The site is secure. Sober and Wilson (1998) are rightI believein claiming that between-group dynamics are the architect of certain remarkable human altruistic dispositions. In the absence of these prosocial dispositions, it is safe to assume that we would apply our reasoning processes in our self-interest and the interest of close kin. Influential scholars such as David Wilson (1975, 2005) and Elliot Sober and Wilson (1998) have developed group selection accounts of human altruism and many have followed their lead. [21] Psychopathy to altruism: Neurobiology of the selfishselfless spectrum. There is equally good evidence for the prevalence of these activities in all human societies. The one-shot reciprocity scenario goes as follows: the tourist pays a fee to the host, who is the service provider. Fisher, R. A. Correspondence to A fine regulation of altruism can be associated with gratitude and sympathy in terms of cost/benefit and the level in which the beneficiary will reciprocate. 2014; Richerson et al. The Evolutionary Biology of Altruism. Psychological Science, 22, 267273. Neuroscience and Neuroeconomics, 5, 6575. Shayna A. Wrighten, Chelsea R. Hall, KEYWORDS: This is mutualistically beneficial, as the bees get to eat and the flowers get pollinated. doi:10.1016/0022-5193(64)90039-6. ), Handbook of evolutionary ethics (pp. 'Reciprocal Altruism' published in 'Encyclopedia of Evolutionary Psychological Science' Intrigued by the logic and determined to solve the evolutionary problem of altruism between unrelated individuals, in 1971, Robert Trivers introduced a theoretical model to account for the natural selection of altruistic behavior between unrelated individuals in the first of a series of revolutionary papers .

A theory of group selection. Altruistic behavior: Mapping responses in the brain. This philosophical view suggests the source of all human motivation is purely self-interest. Neurocognitive adaptations designed for social exchange. Boehm, C. (1997). This constraint imposes both a spatial and a temporal condition on the cleaner and on its host. The evolution of altruism and the serial rediscovery of the role of In such a context, between group dynamics must have been a prominent driver of cultural evolution. In B. Linsky and M. Matthen (eds. Behavioral and Brain Sciences, 35(1), 2021. A stable evolutionary equilibrium could include a low percentage of mimics in controversial support of adaptive sociopathy. Berlin: Springer. Trends in Cognitive Sciences, 15(5), 218226. Science, 293(5537), 21052108. Fehr, E., & Gchter, S. (2002a). in those genetically related organisms). [26] Therefore, the time or frequency of reciprocal actions contributes more to an individual's choice of partner than the reciprocal act itself. Finally, it allows for cooperative child rearing, in which allo-parents share some of the long and arduous work to raise children. When you agreed to this scheme, what was the first thing that crossed your mind? Mothers and others: The evolutionary origins of mutual understanding. Fletcher, J., & Doebeli, M. (2009). Later, Hamilton (1964) developed and formalized the concept of inclusive fitness. Hill, K. R., Walker, R., Boievi, M., Eder, J., Headland, T., Hewlett, B., et al. Commentary on Wilson & Sober: Group selection". Front Psychol. Youve prepaid for this experience, so there is no incentive for the tour guide to actually provide you with the experience they claimed since they have received the full payment beforehand. Many people are also willing to incur costs to punish those who have harmed the group or others. It is not always clear what exactly group selection refers to and different scholars use it in different ways. As I will argue in the next section, underlying actual altruistic behavior are not merely evolved intuition and emotion-based dispositions but also conscious and voluntary reasoning processes. Okasha 2005; Fletcher and Doebeli 2009; Bravetti and Padilla 2018). Human altruism directed at non-kin with no chance of reciprocation cannot be satisfactorily explained in terms of kin selection or reciprocal altruism. Nevertheless, there appears to be a considerable amount of human altruistic behavior that cannot be. Studies have also shown that rats exhibit these altruistic behaviors without the presence of a tangible reward, a primary component in the definition of altruism. Effect of Socioeconomic Status on Altruistic Behavior in Chinese Middle School Students: Mediating Role of Empathy. The theory of reciprocal altruism in humanity, based on the biological characteristics of human beings and the realistic society, explicates the interdependence and cooperation between people, as well as its rationality. Grooming, gossip and the evolution of language. Oda, R. (1997). The evolution of altruistic cooperative behaviorin which an organisms action reduces its fitness and increases the fitness of another organism (e.g. Here is one of many interesting examples of biological altruism. Imagine you are on vacation in Rome and have joined a tour group led by a local. Bethesda, MD 20894, Web Policies Therefore, they argue, human altruistic dispositions were adaptive in our ancestral context (which is why they evolved), but are actually maladaptive in the modern context. (2011). In W. G. Runciman, J. Maynard Smith, & R. I. M. Dunbar (Eds. 7, 8 Similarly, experimental tests of contingent partner choice in relation to altruism received are equally rare. official website and that any information you provide is encrypted Oxford: Clarendon Press. Theoretical models of the evolution of altruism by reciprocal partner choice are rare, possibly because of the difficulties of handling payoff matrices involving multiple individuals. Maybe you thought this is a stupid idea, I could get in trouble. Language enabled our ancestors to form close ties with a relatively large number of individuals (about 150 individuals according to Dunbar) and enabled them to acquire and transmit information to others. In the scientific literature on altruism, however, altruism does not take on this vernacular sense but refers to either psychological or biological altruism. Understanding and sharing intentions: The origins of cultural cognition. How is this possible? In evolutionary biology, reciprocal altruism is a behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism's fitness, with the expectation that the other organism will act in a similar manner at a later time.
