Researchers used various hypotheses to determine if cross-country differences in trust and cooperation would predict prosocial COVID-19 responses and policies. Using individual surveys from 34,526 participants from 41 countries, there were no significant associations between trust and cooperation and prosocial behavior, motivation, regulation, or stringency of policies. While the researchers did find significant variation among cross-country individuals, these results were unable to predict country-level prosocial responses.

This paper seeks to understand how the conflict resolution strategies of indigenous and non-indigenous groups differ in their efficacy. The authors suggest that indigenous methods of conflict resolution are more effective than non-indigenous methods by demonstrating that subjects from the Outline of Cultural Materials (OCM) associated with indigenous conflict management (ICM) will co-occur less frequently with OCM terms related to conflict than subjects related to non-ICM. They tested this by selecting OCM subjects that they felt best represented ICM, non-ICM, and instances of conflict and using chi-square tests to show how often these subjects co-occurred. They subsequently split up the "conflict" variable into four forms of conflict in order to show whether any of these forms might be more frequently found associated with ICM or non-ICM subjects. The results showed that conflict subjects were more likely to co-occur with non-ICM subjects, and that sociocultural/interpersonal conflicts were more likely to be associated with ICM subjects, whereas political conflicts were more likely to be associated with non-ICM subjects.

This article presents the results of economic behavior experiments conducted on members of 15 small scale societies. Although three different economic experiments were conducted, findings focus on the results of the "Ultimatum Game." The authors found that no society adhered to behavior predicted by the "selfishness axiom" which suggests that individuals will behave in a way that maximizes their own gain. Authors also discuss possible predictors of behavioral variation within and between groups.

How do men and women cooperate with others? Previous research has claimed that men and women cooperate in different manners. However, using a meta-analytic approach, the authors of this article find that men and women actually cooperate to a similar extent. They consider differences in cooperation to be a response to specific societal situations and contexts.

This study tests the relationship between supernatural punishment (indexed by the importance of moralizing "high gods") and several proxy measures of cooperation. Results suggest that the presence of high gods is associated with money and credit, credit source, community size, jurisdictional hierarchy beyond the local community, and sanctions.

In this two-part study, researchers first collect data from 600 people from 8 different societies in an effort to examine the character of morality cross-culturally. In the second part, participants play a game to detect honesty and responses are related to conception of morality and religious beliefs. Researchers posit that there is a cooperative nature to conception of morality and that moral culture is related to impact upon one's social life, but that this conceptualization of morality only weakly predicts cooperative behavio. The religious beliefs are stronger predictors.

In this article, the author seeks to correlate interpersonal values with attitudes toward private property. After giving a brief intellectual history on the philosophy of private property, the author draws data from the Multinational Student Survey (MSS) in order to discern attitudes towards private property and preferences for one of six psychological constructs (Support, Conformity, Recognition, Independence, Benevolence, Leadership) which were outlined in the Survey of Interpersonal Values which was itself incorporated in the aforementioned MSS. These measures were then edited in order to be correlated and the reliability of each was verified. The strongest correlations that resulted were for dominance and nonconformity. The author concludes without a theory of how to reckon with these seemingly paradoxical results.

This paper presents a series of predictions that are derived from the assumption that kin selection an altruism are evolved components of human social behavior. Several examples from the anthropological literature that pertain to these predictions are discussed. Data presented are mostly consistent with the predictions.

This paper is an investigation into the relationship between social differentiation as a proxy for societal 'development' and various categories of crime. A positive relationship is interpreted by the author as empirical cross-cultural support for Durkheim's theory that these two factors will increase together as parallel processes of 'sociocultural evolution'.

The authors of this exploratory study tested predictions from five different theoretical models for the evolution of ethnoscientific expertise. They claim support for three of the models. They then compared cultural variables and their five models to three different knowledge domains: conceptual (unable to be easily observed), motor (easily observable), and medicinal. Their results indicate that their cultural transmission model is associated with the motor knowledge domain and that their proprietary knowledge model is associated with the medicinal knowledge domain.
