The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions provide the selection pressures necessary for the evolution of advanced cognitive abilities (the ‘social intelligence hypothesis’), and in recent years decision-making in the context of cooperative social interactions has been conjectured to be of particular importance. Here we use an artificial neural network model to show that selection for efficient decision-making in cooperative dilemmas can give rise to selection pressures for greater cognitive abilities, and that intelligent strategies can themselves select for greater intelligence, leading to a Machiavellian arms race. Our results provide mechanistic support for the social intelligence hypothesis, highlight the potential importance of cooperative behaviour in the evolution of intelligence and may help us to explain the distribution of cooperation with intelligence across taxa.

According to the social intelligence hypothesis, understanding the cognitive demands of the social environment is key to understanding the evolution of intelligence. Many important socio-cognitive abilities, however, have primarily been studied in a narrow subset of the social environment—within-group social interactions—despite the fact that between-group social interactions often have a substantial effect on fitness. In particular, triadic awareness (knowledge about the relationships and associations between others) is critical for navigating many types of complex social interactions, yet no existing study has investigated whether wild animals can track associations between members of other social groups. We investigated inter-group triadic awareness in wild acorn woodpeckers ( Melanerpes formicivorus ), a socially complex group-living bird. We presented woodpeckers with socially incongruous playbacks that simulated two outsiders from different groups calling together, and socially congruous playbacks that simulated two outsiders from the same group calling together. Subjects responded more quickly to the incongruous playbacks, suggesting that they were aware that the callers belonged to two different groups. This study provides the first demonstration that animals can recognize associations between members of other groups under natural circumstances, and highlights the importance of considering how inter-group social selection pressures may influence the evolution of cognition.

Specific Cognitive Abilities

Although intelligence should theoretically evolve to help animals solve specific types of problems posed by the environment, it is unclear which environmental challenges favour enhanced cognition, or how general intelligence evolves along with domain-specific cognitive abilities. The social intelligence hypothesis posits that big brains and great intelligence have evolved to cope with the labile behaviour of group mates. We have exploited the remarkable convergence in social complexity between cercopithecine primates and spotted hyaenas to test predictions of the social intelligence hypothesis in regard to both cognition and brain size. Behavioural data indicate that there has been considerable convergence between primates and hyaenas with respect to their social cognitive abilities. Moreover, compared with other hyaena species, spotted hyaenas have larger brains and expanded frontal cortex, as predicted by the social intelligence hypothesis. However, broader comparative study suggests that domain-general intelligence in carnivores probably did not evolve in response to selection pressures imposed specifically in the social domain. The cognitive buffer hypothesis, which suggests that general intelligence evolves to help animals cope with novel or changing environments, appears to offer a more robust explanation for general intelligence in carnivores than any hypothesis invoking selection pressures imposed strictly by sociality or foraging demands.

The prevailing hypotheses for the evolution of cognition focus on either the demands associated with group living (the social intelligence hypothesis (SIH)) or ecological challenges such as finding food. Comparative studies testing these hypotheses have generated highly conflicting results; consequently, our understanding of the drivers of cognitive evolution remains limited. To understand how selection shapes cognition, research must incorporate an intraspecific approach, focusing on the causes and consequences of individual variation in cognition. Here, we review the findings of recent intraspecific cognitive research to investigate the predictions of the SIH. Extensive evidence from our own research on Australian magpies ( Cracticus tibicen dorsalis ), and a number of other taxa, suggests that individuals in larger social groups exhibit elevated cognitive performance and, in some cases, elevated reproductive fitness. Not only do these findings demonstrate how the social environment has the potential to shape cognitive evolution, but crucially, they demonstrate the importance of considering both genetic and developmental factors when attempting to explain the causes of cognitive variation. This article is part of the theme issue ‘Causes and consequences of individual differences in cognitive abilities’.

Social Decision Making

According to the social intelligence hypothesis, the unusual enlargement of primate brains, including the human brain, was driven by the complexity of social decision-making primates face in their societies. Social decision-making is fundamentally more complex due to the recursive nature of social reasoning. This chapter begins with the review of game theory and illustrates how game theory has transformed neuroscience research on social decision-making. Some of the topics covered include the supposed death of game theory, altruism and its dark side, cooperation, the theory of the mind, the prisoner’s dilemma, the recursive mind, and the social brain.

This paper is about the evolution of hominin intelligence. I agree with defenders of the social intelligence hypothesis in thinking that externalist models of hominin intelligence are not plausible: such models cannot explain the unique cognition and cooperation explosion in our lineage, for changes in the external environment (e.g. increasing environmental unpredictability) affect many lineages. Both the social intelligence hypothesis and the social intelligence–ecological complexity hybrid I outline here are niche construction models. Hominin evolution is hominin response to selective environments that earlier hominins have made. In contrast to social intelligence models, I argue that hominins have both created and responded to a unique foraging mode; a mode that is both social in itself and which has further effects on hominin social environments. In contrast to some social intelligence models, on this view, hominin encounters with their ecological environments continue to have profound selective effects. However, though the ecological environment selects, it does not select on its own. Accidents and their consequences, differential success and failure, result from the combination of the ecological environment an agent faces and the social features that enhance some opportunities and suppress others and that exacerbate some dangers and lessen others. Individuals do not face the ecological filters on their environment alone, but with others, and with the technology, information and misinformation that their social world provides.

Evolutionary Consequences

The requirements of living in social groups, and forming and maintaining social relationships are hypothesized to be one of the major drivers behind the evolution of cognitive abilities. Most empirical studies investigating the relationships between sociality and cognition compare cognitive performance between species living in systems that differ in social complexity. In this review, we ask whether and how individuals benefit from cognitive skills in their social interactions. Cognitive abilities, such as perception, attention, learning, memory, and inhibitory control, aid in forming and maintaining social relationships. We investigate whether there is evidence that individual variation in these abilities influences individual variation in social relationships. We then consider the evolutionary consequences of the interaction between sociality and cognitive ability to address whether bi-directional relationships exist between the two, such that cognition can both shape and be shaped by social interactions and the social environment. In doing so, we suggest that social network analysis is emerging as a powerful tool that can be used to test for directional causal relationships between sociality and cognition. Overall, our review highlights the importance of investigating individual variation in cognition to understand how it shapes the patterns of social relationships. This article is part of the theme issue ‘Causes and consequences of individual differences in cognitive abilities’.

AbstractThis paper examines the collaborative use of visual argument maps in the context of argument production in organizations. Argument maps are highly multimodal, as their use involves the combination of diagrams, text elements, as well as spoken statements. In this theoretical piece, we apply a Collaborative Dimensions framework to argument maps that can be used to better design, understand, evaluate, and use argument maps in collaborative settings for decision making purposes. Specifically, our conceptual framework – derived from interdisciplinary perspectives – takes into consideration how the visual dimensions of argument maps have a bearing on the social interactions of people involved in a complex argumentation process. We posit that cognitive dimensions of argument maps need to be enriched with additional communicative and collaborative dimensions in order to foster a more widespread adoption of argument mapping in organizational decision making. In our socio-visual approach to argument mapping, we thus distinguish the following seven dimensions: Visual Insight, Outcome Clarity, Directed Focus, Perceived Finishedness, Visual Appeal, Content Modifiability, and Collaboration Support. We illustrate the use of the framework as an evaluation tool and analyze three different approaches to argument mapping with the help of the seven dimensions. In this way, the framework can be used to improve collaborative argument mapping. Our contribution thus lies in proposing an interdisciplinary and theoretically grounded set of factors to augment the quality of argument maps, both from a process and a results perspective. In this manner we hope to contribute to the theory of argumentation through the rich notion of “collaborative dimensions,” as well as further the practice of collaborative argument production through a more reflective and systematic use of interactive argument visualization.

Tanulmányunkban a tehetség két aspektusát elemezzük. Az egyik szinten arra a kérdésre keresünk választ, hogy milyen örökletes tényezők tehetők felelőssé a lángész kialakulásáért. Megállapítjuk, hogy a jelenlegi kutatások szerint a tehetség mögött nem fedezhetők fel specifikus gének, de lehetségesek olyan genetikai hatások, amelyek egyfajta emergens szerveződése teremti meg az alapját a lángész kialakulásának – természetesen a különböző környezeti hatásokkal kölcsönhatásban. A másik szintű elemzésben a tehetség evolúciós eredetére kérdezünk rá, és négy olyan humánspecifikus kognitív képesség kialakulását elemezzük, amelyek fontos szerepet játszhatnak a szellemi kiválóság megjelenésében. Nevezetesen arra teszünk kísérletet, hogy megértsük az elmeolvasás, rugalmas gondolkodás, nyelv és kreativitás evolúciós létrejöttét. Ehhez olyan magyarázó model-leket veszünk igénybe, mint a Szociális Intelligencia, Machiavelli Intelligencia, Szexuális Szelekció és Fluid Intelligencia hipotézisek. E magyarázatok megerősítése további kutatásokat igényel.In this paper, two aspects of talent are analyzed. On the one level, I am looking for an answer to what hereditary factors would be responsible for the development of talent. In the light of the current studies, no specific genes have been found to prescribe talent. However, possible genetic effects with an emergent property of their mutual relationships may create the basis of formation of genius – obviously interacting with the environmental effects. On the other level of analysis I am focusing on the evolutionary background of talent. Four human specific cognitive abilities are analyzed that play important roles in the formation of intellectual excellence: mind reading, flexible thought, language, and creativity. The explanations to the evolution of these abilities include Social Intelligence Hypothesis, Machiavellian Intelligence Hypothesis, Sexual Selection Theory, and Fluid Intelligence Hypothesis. The confirmation of these explanations requires further studies.

Machiavellian Intelligence

The first discussion of a relationship between sociality and intelligence came in the middle of the twentieth century, especially by Humphrey who suggested that living socially demanded intellectual abilities above and beyond those required by an animal’s ecology. This led to the Social Intelligence Hypothesis, and then the Machiavellian Intelligence Hypothesis, both proposing that sociality was the main driver of the superior intellect of primates, especially humans. Two key challenges for this hypothesis are that sociality is difficult to quantify and cognition is not well tested by problem solving. More importantly, as data from more species have been examined, the analyses increasingly fail to show that sociality explains variation in brain size, even in primates. I conclude that appealing as this hypothesis is, it does not do a very compelling job of explaining variation in brain size.
