Human cultures through the scientific lens : essays in evolutionary cognitive anthropology

---

1. Anthropology, Useful and Scientific: An Introduction

This presents, very briefly, the project of a cultural anthropology that is informed by evolutionary biology, psychology and economics. This "consilient” version of the social sciences, to adopt EO Wilson’s terminology, is based on the idea that we cannot understand human cultures in their diversity and commonalities, without this perspective. The introduction then provides a brief survey of the volume.

2. Institutions and Human Nature

Most standard social science accounts only offer limited explanations of institutional design, i.e. why institutions have common features observed in many different human groups. Here we suggest that these features are best explained as the outcome of evolved human cognition, in such domains as mating, moral judgment and social exchange. As empirical illustrations, we show how this evolved psychology makes marriage systems, legal norms and commons management systems intuitively obvious and compelling, thereby ensuring their occurrence and cultural stability. We extend this to propose under what conditions institutions can become ‘natural’, compelling and legitimate, and outline probable paths for institutional change given human cognitive dispositions. Explaining institutions in terms of these exogenous factors also suggests that a general theory of institutions as such is neither necessary nor in fact possible. What are required are domain-specific accounts of institutional design in different domains of evolved cognition.

3. Why Ritualized Behavior?

Ritualized behavior, intuitively recognizable by its stereotypy, rigidity, repetition, and apparent lack of rational motivation, is found in a variety of life conditions, customs, and everyday practices: in cultural rituals, whether religious or non-religious; in many children’s complicated routines; in the pathology of obsessive-compulsive disorders (OCD); in normal adults around certain stages of the life-cycle, birthing in particular. Combining evidence from evolutionary anthropology, neuropsychology and neuroimaging, we propose an explanation of ritualized behavior in terms of an evolved Precaution System geared to the detection of and reaction to inferred threats to fitness. This system, distinct from fear-systems geared to respond to manifest danger, includes a repertoire of clues for potential danger as well as a repertoire of species-typical precautions. In OCD pathology, this system does not supply a negative feedback to the appraisal of potential threats, resulting in doubts about the proper performance of precautions, and repetition of action. Also, anxiety levels focus the attention on low-level gestural units of behavior rather than on the goal-related higher-level units normally used in parsing the action-flow. Normally automatized actions are submitted to cognitive control. This "swamps” working memory, an effect of which is a temporary relief from intrusions but also their long-term strengthening. Normal activation of this Precaution System explains intrusions and ritual behaviors in normal adults. Gradual calibration of the system occurs through childhood rituals. Cultural mimicry of this system’s normal input makes cultural rituals attention-grabbing and compelling. A number of empirical predictions follow from this synthetic model.

4. Social Groups and Adapted Minds

Contacts between people from different groups engage a variety of human competencies and motivations, from high-level representations of social categories to visceral responses when confronted with strangers, from cognitive appraisal of conflict to a desire to exclude or even attack "others.” There is a correspondingly diverse set of fields and subfields in psychology and the social sciences focusing on such specific topics as racial prejudice, in-group bias, ethnic identity, xenophobia, and nationalism. In this article, we propose a model that cuts across boundaries between these different fields to describe and explain fundamental aspects of intergroup relations. We propose that many aspects of intergroup relations should be construed as different manifestations of a coalitional psychology. We describe coalitional psychology as a set of evolved mechanisms designed to garner support from conspecifics, organize and maintain alliances, and increase an alliance’s chance of success against rival coalitions. In this perspective, the core psychological mechanisms are the same, independent of whether the alliance in question is formed as ethnic (based on perceived similarity and common origin), racial (based on ethnicity combined with phenotypic similarity), regional, or political, and so forth.
