Abstract: Darwin-inspired population thinking suggests approaching culture as a population of items of different types, whose relative frequencies may change over time. Three nested subtypes of populational models can be distinguished: evolutionary, selectional and replicative. … we describe cultural evolution in terms of cultural attraction, which is populational and evolutionary, but only selectional under certain circumstances. …
Abstract: Little is known about the spread of emotions beyond dyads. Yet, it is of importance for explaining the emergence of crowd behaviors. Here, we experimentally addressed whether emotional homogeneity within a crowd might result from a cascade of local emotional transmissions where the perception of another’s emotional expression produces, in the observer’s face and body, sufficient information to allow for the transmission of the emotion to a third party. … [Our] findings demonstrate that one is tuned to react to others’ emotional signals and to unintentionally produce subtle but sufficient emotional cues to induce emotional states in others…
Abstract: In “The evolution of testimony: Receiver vigilance, speaker honesty, and the reliability of communication,” Kourken Michaelian questions the basic tenets of our article “Epistemic vigilance” (Sperber et al. 2010). Here I defend against Michaelian’s criticisms the view that epistemic vigilance plays a major role in explaining the evolutionary stability of communication and that the honesty of speakers and the reliability of their testimony are, to a large extent, an effect of hearers’ vigilance.
Abstract: What makes humans moral beings? This question can be understood either as a proximate ‘how’ question or as an ultimate ‘why’ question. The ‘how’ question is about the mental and social mechanisms that produce moral judgments and interactions, and has been investigated by psychologists and social scientists. The ‘why’ question is about the fitness consequences that explain why humans have morality, and has been discussed by evolutionary biologists in the context of the evolution of cooperation. Our goal here is to contribute to a fruitful articulation of such proximate and ultimate explanations of human morality. We do so by developing an approach focusing on recent developments in the study of mutualistic forms of cooperation and on their relevance to fairness-based morality.
Abstract: From an evolutionary point of view, the function of moral behaviour may be to secure a good reputation as a co-operator. The best way to do so may be to obey genuine moral motivations. Still, one’s moral reputation maybe something too important to be entrusted just to one’s moral sense. A robust concern for one’s reputation is likely to have evolved too. Here we explore some of the complex relationships between morality and reputation both from an evolutionary and a cognitive point of view.
“…We argue that the function of reasoning is primarily social and that it is the individual benefits that are side-effects. The function of reasoning is to produce arguments in order to convince others and to evaluate arguments others use in order to convince us. We will show how this view of reasoning as a form of social competence correctly predicts both good and bad performance in the individual and in the collective case, and helps explain a variety of psychological and sociological phenomena…”
A short and popular presentation of the notion of ‘cultural attractor’.
Abstract: Reasoning is generally seen as a mean to improve knowledge and make better decisions. Much evidence, however, shows that reasoning often leads to epistemic distortions and poor decisions. This suggests rethinking the function of reasoning. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given human exceptional dependence on communication and vulnerability to misinformation. A wide range of evidence in the psychology or reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis.
Abstract: Humans depend massively on communication with others, but this leaves them open to the risk of being accidentally or intentionally misinformed. We claim that humans have a suite of cognitive mechanisms for epistemic vigilance to ensure that communication remains advantageous despite this risk. Here we outline this claim and consider some of the ways in which epistemic vigilance works in mental and social life by surveying issues, research and theories in different domains of philosophy, linguistics, cognitive psychology and the social sciences.

Abstract: Social learning mechanisms are usually assumed to explain both the spread and the persistence of cultural behaviour. In a recent article, we showed that the fidelity of social learning commonly found in transmission chain experiments is not high enough to explain cultural stability. Here we want to both enrich and qualify this conclusion by looking at the case of song transmission in song birds, which can be faithful to the point of being true replication. We argue that this high fidelity results from natural selection pressure on cognitive mechanisms. This observation strengthens our main argument. Social learning mechanisms are unlikely to be faithful enough to explain cultural stability because they are generally selected not for high fidelity but for generalisation and adjustment to the individual’s needs, capacities and situation.
Abstract: For acquired behaviour to count as cultural, two conditions must be met: it must propagate in a social group, and it must remain stable across generations in the process of propagation. It is commonly assumed that imitation is the mechanism that explains both the spread of animal culture and its stability. We review the literature on transmission chain studies in chimpanzees and other animals, and we use a formal model to argue that imitation, which may well play a major role in the propagation of animal culture, cannot be considered faithful enough to explain its stability. We consider the contribution that other psychological and ecological factors might make to the stability of animal culture observed in the wild.
Abstract: We propose a principled distinction between two types of inferences: ‘intuitive inference’ and ‘reflective inference’ (or reasoning proper). We ground this distinction in a massively modular view of the human mind where metarepresentational modules play an important role in explaining the peculiarities of human psychological evolution. We defend the hypothesis that the main function of reflective inference is to produce and evaluate arguments occurring in interpersonal communication (rather than to help individual ratiocination). This function, we claim, helps explain important aspects of reasoning. We review some of the existing evidence and argue that it gives support to this approach.
Abstract: Vigilance towards deception is investigated in 3- to-5-year-old children: (i) In study 1, children as young as 3 years of age prefer the testimony of a benevolent rather than of a malevolent communicator. (ii) In study 2, only at the age of four do children show understanding of the falsity of a lie uttered by a communicator described as a liar. (iii) In study 3, the ability to recognize a lie when the communicator is described as intending to deceive the child emerges around four and improves throughout the fifth and sixth year of life. On the basis of this evidence, we suggest that preference for the testimony of a benevolent communicator, understanding of the epistemic aspects of deception, and understanding of its intentional aspects are three functionally and developmentally distinct components of epistemic vigilance.
Abstract: Most human beliefs are acquired through communication, and so are most misbeliefs. Just like the misbeliefs discussed by McKay & Dennett (M&D), culturally transmitted misbeliefs tend to result from limitations rather than malfunctions of the mechanisms that produce them, and few if any can be argued to be adaptations. However, the mechanisms involved, the contents, and the hypothetical adaptive value tend to be specific to the cultural case.
Abstract: We argue that there is a continuum of cases without any demarcation between more individual and more cultural information, and that therefore “culture” should be viewed as a property that human mental representations and practices exhibit to a varying degree rather than as a type or a subclass of these representations and practices (or of “information”). We discuss the relative role of preservative and constructive processes in transmission. We suggest a revision of Richerson and Boyd’s classification of the forces of cultural evolution.
Abstract: Henrich and Boyd (2002) were the first to propose a formal model of the role of attraction in cultural evolution. They came to the surprising conclusion that, when both attraction and selection are at work, final outcomes are determined by selection alone. Th is result is based on a determistic view of cultural attraction, different from the probabilistic view introduced in Sperber (1996). We defend this probabilistic view, show how to model it, and argue that, when both attraction and selection are at work, both affect final outcomes.

“…Domesticated plants and animals have simultaneously biological, cultural, and artifactual functions… How should we describe these functions and their articulation? What are the biological and cultural functions of seedless grapes, or of suntans, and how do these functions interact? In trying to answer such questions, we are led to rethink the relationship between nature and culture, and to reappraise the notion of an artifact….”

“…Une nouvelle branche de la linguistique, la pragmatique, s’est développé au cours des dernières décennies. Elle étudie la compréhension des énoncés en contexte. Qui adopte une perspective pragmatique est amené à concevoir les énoncés non tant comme des moyens qu’utilise le locuteur pour transmettre au moyen de sons le sens qu’il veut communiquer, mais plutôt comme des indices riches et complexes que le locuteur fourni à l’auditeur afin de lui permettre de reconstruire le sens voulu… Nous nous interrogerons ici sur les conséquences de la perspective pragmatique pour l’étude de l’évolution du langage…”

Abstract: The existence and diversity of human cultures are made possible by our species-specific cognitive capacities. But how? Do cultures emerge and diverge as a result of the deployment, over generations and in different populations, of general abilities to learn, imitate and communicate? What role if any do domain-specific evolved cognitive abilities play in the emergence and evolution of cultures? These questions have been approached from different vantage points in different disciplines. Here we present a view that is currently developing out of the converging work of developmental psychologists, evolutionary psychologists and cognitive anthropologists.
We begin, with a short presentation of Cosmides’s social contract hypothesis, of Wason selection task, and of Cosmides’s reasons to use the task in order to test the theory. In a second section, we present the relevance-theoretic analysis of the selection task proposed by Sperber, Cara and Girotto (1995) which cast doubts on the appropriateness of the task to study reasoning. In a third section, we present Fiddick, Cosmides and Tooby’s (2000) defense of the use of the selection task as a tool to test evolutionary theories of reasoning, and argue that it is methodologically flawed. In a fourth section, we present three experiments designed to test contrasting predictions deriving from the two approaches. In the conclusion, we come back to Cosmides’s hypothesis and reflect on how it might be really tested…”
Abstract: Sperber, Cara, and Girotto (1995) argued that, in Wason’s selection task, relevance-guided comprehension processes tend to determine participants’ performance and pre-empt the use of other inferential capacities. Because of this, the value of the selection task as a tool for studying human inference has been grossly overestimated. Fiddick, Cosmides, and Tooby (2000) argued against Sperber et al. that specialized inferential mechanisms, in particular the “social contract algorithm” hypothesized by Cosmides (1989), pre-empt more general comprehension abilities, making the selection task a useful tool after all. We rebut this argument. We argue and illustrate with two new experiments, that Fiddick et al. mix the true Wason selection task with a trivially simple categorization task superficially similar to the Wason task, yielding methodologically flawed evidence. We conclude that the extensive use of various kinds of selection tasks in the psychology of reasoning has been quite counter-productive and should be discontinued.
Abstract: This article revisits the old controversy concerning the relation of the mother’s brother and sister’s son in patrilineal societies in the light both of anthropological criticisms of the very notion of kinship and of evolutionary and epidemiological approaches to culture. It argues that the ritualized patterns of behavior discussed by Radcliffe-Brown, Goody, and others are to be explained in terms of the interaction of a variety of factors, some local and historical, others pertaining to general human dispositions. In particular, an evolved disposition to favor relatives can contribute to the development and stabilization of these behaviors not by directly generating them but by making them particularly “catchy” and resilient. In this way, it is possible to recognize both that cultural representations and practices are specific to a community at a time in its history (rather than mere tokens of a general type) and that they are, in essential respects, grounded in the common evolved psychology of human beings.
Abstract: The central problem for pragmatics is that sentence meaning vastly underdetermines speaker’s meaning. The goal of pragmatics is to explain how the gap between sentence meaning and speaker’s meaning is bridged. This paper defends the broadly Gricean view that pragmatic interpretation is ultimately an exercise in mind-reading, involving the inferential attribution of intentions. We argue, however, that the interpretation process does not simply consist in applying general mind-reading abilities to a particular (communicative) domain. Rather, it involves a dedicated comprehension module, with its own special principles and mechanisms. We show how such a metacommunicative module might have evolved, and what principles and mechanisms it might contain.

Abstract: To approach society and culture in a naturalistic way, the domain of the social sciences must be reconceptualised by recognising only entities and processes of which we have a naturalistic understanding. These are mental representations and public productions, the processes that causally link them, the causal chains that bond these links, and the complex webs of such causal chains that criss-cross human populations over time and space. Such causal chains may distribute and stabilise representations and productions throughout a human population, thereby generating culture. The lecture introduces several conceptual tools useful for such a naturalistic approach, and illustrates their use with the case study of ritual activity in a Southern Ethiopian household.
Résumé : Pour aborder la société et la culture d’une manière naturaliste, il faut reconceptualiser le domaine du social en n’y reconnaissant que des entités et des processus dont nous avons une compréhension naturaliste. Il s’agira de représentations mentales et de productions publiques, des processus qui les lient causalement, des chaînes causales qui associent ces liens, et des réseaux complexes de ces chaînes causales qui parcourent en tous sens les populations humaines dans le temps et l’espace. De telles chaînes causales peuvent distribuer et stabiliser des représentations et des productions à travers une population humaine et ainsi engendrer de la culture. Ce texte introduit plusieurs outils conceptuels pour développer cette approche naturaliste et l’illustre par une étude de cas portant sur une activité rituelle dans une maisonnée du sud de l’Éthiopie.
“Language is both a biological and a cultural phenomenon. Our aim here is to discuss, in an evolutionary perspective, the articulation of these two aspects of language. For this, we draw on the general conceptual framework developed by Ruth Millikan (1984) while at the same time dissociating ourselves from her view of language…”
“Memetics is one possible evolutionary approach to the study of culture. Boyd and Richerson’s models (1985), or my epidemiology of representations (1985, 1996), are among other possible evolutionary approaches inspired in various ways by Darwin. Memetics however, is, by its very simplicity, particularly attractive…”

“Most work in the cognitive sciences focuses on the manner in which an individual device — be it a mind, a brain, or a computer — processes various kinds of information. Cognitive psychology in particular is primarily concerned with individual thought and behavior. Individuals however belong to populations. This is true in two quite different senses. Individual organisms are members of species and share a genome and most phenotypic traits with the other members of the same species. Organisms essentially have the cognitive capacities characteristic of their species, with relatively superficial individual variations. In social species, individuals are also members of groups. An important part of their cognitive activity is directed toward other members of the group with whom they cooperate and compete. Among humans in particular, social life is richly cultural. Sociality and culture are made possible by cognitive capacities, contribute to the ontogenetic and phylogenetic development of these capacities, and provide specific inputs to cognitive processes…”
