Culture-gene coevolution, norm-psychology and the emergence of human prosociality

Diverse lines of theoretical and empirical research are converging on the notion that human evolution has been substantially influenced by the interaction of our cultural and genetic inheritance systems. The application of this culture-gene coevolutionary approach to understanding human social psychology has generated novel insights into the cognitive and affective foundations of large-scale cooperation, social norms and ethnicity. This approach hypothesizes a norm-psychology: a suite of psychological adaptations for inferring, encoding in memory, adhering to, enforcing and redressing violations of the shared behavioral standards of one's community. After reviewing the substantial body of formal theory underpinning these predictions, we outline how this account organizes diverse empirical findings in the cognitive sciences and related disciplines. Norm-psychology offers explanatory traction on the evolved psychological mechanisms that underlie cultural evolution, cross-cultural differences and the emergence of norms.     

Social Context and the Dynamics of Cooperative Choice

Recent work using decontextualized economic games suggests that cooperation is a dynamic decision‐making process: Automatic responses typically support cooperation on average, while deliberation leads to increased selfishness. Here, we performed two studies examining how these temporal effects generalize to games with richer social context cues. Study 1 found that time pressure increased cooperation to a similar extent in games played with in‐group members and out‐group members. Study 2 found that time pressure increased cooperation to a similar extent in games described as competitions and games described as collaborations. These results show that previous positive effects of time pressure on cooperation are not unique to neutrally framed games devoid of social context and are not driven by implicit assumptions of shared group membership or cooperative norms. In doing so, our findings provide further insight into the cognitive underpinnings of cooperative decision making. Copyright © 2014 John Wiley & Sons, Ltd.

How Social Norms Promote Misleading Social Feedback and Inaccurate Self‐Assessment

Self‐assessments are often prone to error. Past research has identified cognitive and motivational biases that lead self‐assessments astray. In the present paper, we discuss how behavior shaped by social norms leaves the negative information that people require for accurate self‐assessments invisible. First, social norms lead people to suppress critical feedback in favor of more positive evaluations. Although people recognize that they prefer to provide positive feedback to others, they fail to consider that they might be the recipient of incomplete feedback. As a result, they are left with overconfident self‐impressions. Second, social norms lead people to hide their own negative emotional experiences from others. Again, people are aware that this positivity norm influences their own behavior but do not apply this knowledge to their understanding of others. As a result, people regard their own negative emotions as more socially aberrant than is actually the case.     

How the Social Environment Shaped the Evolution of Mind

Dominance hierarchies are ubiquitous in the societies of human and non-human animals. Evidence from comparative, developmental, and cognitive psychological investigations is presented that show how social dominance hierarchies shaped the evolution of the human mind, and hence, human social institutions. It is argued that the pressures that arise from living in hierarchical social groups laid a foundation of fundamental concepts and cognitive strategies that are crucial to surviving in social dominance hierarchies. These include recognizing and reasoning transitively about dominance relations, fast-track learning of social norms (permissions, prohibitions, and obligations), detecting violations of social norms (cheating), monitoring reciprocal obligations, and reading the intentions of others.     

第三方惩罚的演化与认知机制

第三方惩罚一般是指当违反社会规范的行为与自身利益无关时,个体牺牲自我利益来惩罚违规者的行为。最近的研究发现,对于个体而言,第三方惩罚是一种具有适应性的信号,包括建立良好的声誉以及威慑违规者。不同情境下第三方惩罚的功能有所差异,它是一种特殊的利他行为。第三方惩罚依赖于多个系统,涉及情绪反应、共情等社会认知能力以及认知控制等中央执行能力。探讨该行为的演化和认知机制也能贡献于个体、群体和人际层面的社会心理服务工作。     

Subclinical Bias,Manners, and Moral Harm

Mundane and often subtle forms of bias generate harms that can be fruitfully understood as akin to the harms evident in rudeness. Although subclinical expressions of bias are not mere rudeness, like rudeness they often manifest through the breach of mannerly norms for social cooperation and collaboration. At a basic level, the perceived harm of mundane forms of bias often has much to do with feeling oneself unjustly or arbitrarily cut out of a group, a group that cooperates and collaborates but does not do so with me. Appealing to the subtle but familiar choreography of mannered social interaction, I argue, makes it easier to recognize how exclusion can be accomplished through slight but symbolically significant gestures and styles of interaction, where bias manifests not in announced hostility but in an absence of the cooperation and collaboration upon which we rely socially.     

Linking self and ingroup: Self‐anchoring as distinctive cognitive route to social identification

The present paper investigates how cognitive projection processes instigate social identification. We complement the classical self‐stereotyping approach (i.e., conforming to prototypical group norms) by investigating self‐anchoring (i.e., projection from self to group) as a distinct cognitive route to social identification. Self‐anchoring has mainly been investigated as predictor of intergroup differentiation. Surprisingly, no reliable link has been provided yet between self‐anchoring and social identification. In Study 1, we provide first evidence for this positive link. In Study 2, we add self‐stereotyping to our model and show that self‐anchoring is still positively related to social identification when controlling for self‐stereotyping. Additionally, we show that self‐anchoring is positively related to affective components of identification, while self‐stereotyping is positively related to cognitive components. Moreover, we examined the impact of self‐concept stability on self‐anchoring. Self‐concept stability was positively related to self‐anchoring, and hence to social identification (Study 1), independently from self‐stereotyping (Study 2). In the discussion, we argue that disentangling self‐anchoring from self‐stereotyping is important as it increases our insight in how people identify, and how this may vary depending on self‐concept and group context.

Socially evaluative contexts facilitate mentalizing

Our ability to understand others’ minds stands at the foundation of human learning, communication, cooperation, and social life more broadly. Although humans’ ability to mentalize has been well-studied throughout the cognitive sciences, little attention has been paid to whether and how mentalizing differs across contexts. Classic developmental studies have examined mentalizing within minimally social contexts, in which a single agent seeks a neutral inanimate object. Such object-directed acts may be common, but they are typically consequential only to the object-seeking agent themselves. Here, we review a host of indirect evidence suggesting that contexts providing the opportunity to evaluate prospective social partners may facilitate mentalizing across development. Our article calls on cognitive scientists to study mentalizing in contexts where it counts.

From cooperation to conflict: The role of collective narratives in shaping group behaviour

In this paper, we review the concept of collective narratives and their role in shaping group behaviour. We see collective narratives as ‘meta-stories’ embraced by groups that incorporate values and beliefs about social reality, therefore providing a blueprint for group norms which, in turn, inform group members' behaviour. Our aim is to both describe the psychological processes underpinning the relation between collective narratives and group behaviours and develop an integrative typology of the functions of collective narratives (as they connect to various collective behaviours). We start by discussing definitions in the recent literature and propose an integrative conceptualisation which positions collective narratives in the context of collective action research. Next, we focus on the process by which collective narratives provide the bases for identity formation, development, and change, thus shaping group behaviour. We see collective narratives as central in understanding group behaviour, as they function as ‘meta-stories’ that incorporate moral codes and values, and beliefs about the ingroups and outgroups—providing a blueprint for group norms which, in turn, inform group members' behaviour. In the second part of the article, we describe a typology of collective narratives according to their functions, structured around two core dimensions: the context/s in which collective narratives develop and are shared (i.e., intragroup vs. intergroup) and their effects within these contexts (i.e., driving consensus vs. driving dissent). We identify four distinctive types of collective narrative functions and review research showing how each of them shapes specific social identity content, including behaviour prescribing norms. We then show how these specific norms shape behaviours ranging from cooperation and pro-social action to hostile intergroup conflict. The implications of this contribution are twofold. First, by providing a systematic account and categorisation of how collective narratives function in society and of their connections to social identities (and their content), we can more accurately deduct group norms and predict behaviours in specific circumstances, including in relation to political violence. Second, by better understanding the narratives that provide the bases of identity formation, development, and change, we can improve attempts to create alternative narratives that unify rather than divide people, so that pathways to co-operation might be chosen over conflict.     

Sharing moral values: anticipated ingroup respect as a determinant of adherence to morality-based (but not competence-based) group norms

This research examines how moral values regulate the behavior of individual group members. It argues that group members behave in line with moral group norms because they anticipate receiving ingroup respect when enacting moral values that are shared by ingroup members. Data from two experimental studies offer evidence in support. In Study 1 (N = 82), morality-based (but not competence-based) ingroup norms determined whether members of a low-status group opted for individual versus collective strategies for status improvement. This effect was mediated by anticipated ingroup respect and emerged regardless of whether group norms prescribed collectivistic or individualistic behavior. These effects were replicated in Study 2 (N = 69), where no comparable effect was found as a result of moral norms communicated by a higher status outgroup. This indicates that social identity implications rather than interdependence or more generic concerns about social approval or importance of cooperation drive these effects.     

Socialization Communication,Organizational Citizenship Behaviors,and Sales in a Multilevel Marketing Organization

Multilevel marketing organizations (MLMs) are a rapidly growing but often controversial marketing organizational type boasting nearly 10 million members and over $20 billion in annual sales. The success of the MLM business model rests largely on forming cooperative social networks of member distributors. Socialization of new members to the norms and values of the MLM plays a key role in eliciting that cooperative behavior. However, the member cooperation that produces successful networks may inhibit the financial performance of individual distributors. Drawing upon social identity theory, this study investigates whether communication of the MLM’s behavioral norms during the socialization of members affects the degree to which members cooperate with each other and how that cooperation affects the sales performance of individual distributorships. The results of a survey of MLM members suggest that both effects occur. Socialization communication positively affects member cooperation, which produces direct and indirect effects on sales. Cooperation, measured by several organizational citizenship behaviors, exerts a positive direct effect on sales, but a negative indirect effect when the relationship is mediated by group cohesion.     

Social class, solipsism, and contextualism: how the rich are different from the poor

Social class is shaped by an individual's material resources as well as perceptions of rank vis-à-vis others in society, and in this article, we examine how class influences behavior. Diminished resources and lower rank create contexts that constrain social outcomes for lower-class individuals and enhance contextualist tendencies--that is, a focus on external, uncontrollable social forces and other individuals who influence one's life outcomes. In contrast, abundant resources and elevated rank create contexts that enhance the personal freedoms of upper-class individuals and give rise to solipsistic social cognitive tendencies--that is, an individualistic focus on one's own internal states, goals, motivations, and emotions. Guided by this framework, we detail 9 hypotheses and relevant empirical evidence concerning how class-based contextualist and solipsistic tendencies shape the self, perceptions of the social environment, and relationships to other individuals. Novel predictions and implications for research in other socio-political contexts are considered.     

第三方惩罚的神经机制：来自经颅直流电刺激的证据

第三方惩罚既是社会规范在群体得以维系的基石, 也是个体维护社会规范的体现。当前关注社会规范的神经研究大多基于第二方惩罚的独裁者或最后通牒实验框架, 缺乏对第三方维护社会规范过程中相关脑区活动的探索, 对这一过程的内在神经机制也不清楚。本文基于第三方惩罚的独裁者博弈框架, 对右侧背外侧前额叶区域(DLPFC)进行不同极性的经颅直流电刺激(tDCS), 同时依据第三方是否需要为其惩罚付出成本设计了零成本和有成本两个实验任务。结果发现, 第三方在零成本任务的情绪反应和惩罚显著受到tDCS设置的影响, 且阴极刺激显著提升了第三方的惩罚值, 这表明情绪机制对第三方惩罚有着重要影响。另外, 第三方在零成本和有成本任务中的惩罚差异在不同tDCS设置之间也存在显著差异, 这与第三方惩罚还受到自利机制影响的观点相符。本文率先为右侧DLPFC活动影响第三方惩罚提供了神经层面的证据, 且支持了第三方对社会规范的遵从与其负性情绪反应和自利加工密切相关的机制解释。     

The essential role of ritual in the transmission and reinforcement of social norms

Social norms are communally agreed upon, morally significant behavioral standards that are, at least in part, responsible for uniquely human forms of cooperation and social organization. This article summarizes evidence demonstrating that ritual and ritualized behaviors are essential to the transmission and reinforcement of social norms. Ritualized behaviors reliably signal an intentional mental state giving credibility to verbal expressions while emotionally binding people to each other and group-based values. Early ritualized infant-caregiver interactions and the family routines and rituals that emerge from them are primary mechanisms for transmitting social norms vertically from parent to offspring, while adult community rituals are a primary mechanism by which norms are reinforced horizontally within the community.     

Cooperation In Group Treatment Programs for Incarcerated Adolescents1

Group treatment programs for incarcerated adolescents attempt to use the social influence of peer groups as a means both for generating acceptance of treatment goals and for creating pro-social change. On the basis of social psychological research in laboratory and educational settings, we predicted that group cooperation plays a pivotal role in these programs. A hypothesized path model was estimated through pooled time series and cross section analysis of three waves of data for 45 groups at four institutions. There was close agreement between path estimates from an analysis of average levels and an analysis of change, and both strongly supported the hypothesized model. Results indicate that coercive control decreases cooperation and that cooperation leads to attraction to the group and prevents delinquent norms. Cooperation also has an indirect effect on acceptance of the program, mediated by attraction to the group.     

THE WICKED PROBLEM OF OUR FAILING SOCIAL COMPACT

The United States is an outlier among nations in its failure to adopt robust climate policy. The underlying cause is not unique to the climate issue. Climate, like growing national debt, embodies a trade‐off between individual consumption now versus investment yielding long‐term societal gain. Over human history, social norms favoring one over the other wax and wane with the pervasiveness of transcendental values as embodied in personal virtue, social connectedness, spirituality, and religious faith. Over the past few decades, many indicators show that American social norms and extended cooperation have weakened. Given entrenched political corruption and continuing institutional failure to address multiple long‐term societal challenges, individuals are called upon personally to practice and to enforce pro‐social norms and to advance high‐leverage systemic changes, some identified in this article, which will allow extended cooperation to once again flourish.
