TL;DR: The differences across cultures in the enforcement of conformity may reflect their specific histories and advances knowledge that can foster cross-cultural understanding in a world of increasing global interdependence and has implications for modeling cultural change.
Abstract: With data from 33 nations, we illustrate the differences between cultures that are tight (have many strong norms and a low tolerance of deviant behavior) versus loose (have weak social norms and a high tolerance of deviant behavior). Tightness-looseness is part of a complex, loosely integrated multilevel system that comprises distal ecological and historical threats (e.g., high population density, resource scarcity, a history of territorial conflict, and disease and environmental threats), broad versus narrow socialization in societal institutions (e.g., autocracy, media regulations), the strength of everyday recurring situations, and micro-level psychological affordances (e.g., prevention self-guides, high regulatory strength, need for structure). This research advances knowledge that can foster cross-cultural understanding in a world of increasing global interdependence and has implications for modeling cultural change.

TL;DR: A study of self-construal involving 5 cultures shows that differences between these cultures are captured mostly by the extent to which people see themselves as acting as independent agents, whereas gender differences are best summarized by the whether people regard themselves as emotionally related to others.
Abstract: Individualism and collectivism are often equated with independent vs. interdependent, agentic vs. communal, and separate vs. relational self-construals. Although these same concepts have been used to characterize both cultural and gender differences, a perspective of cultural evolution suggests it is unlikely. A division of labor within society may produce gender differences, but this cannot explain cultural differences. A study of self-construal involving 5 cultures (Australia, the United States, Hawaii, Japan, and Korea) shows that differences between these cultures are captured mostly by the extent to which people see themselves as acting as independent agents, whereas gender differences are best summarized by the extent to which people regard themselves as emotionally related to others.

TL;DR: In this article, the authors report two studies that examined whether pancultural dimensions based on general beliefs, or social axioms, can be identified in persons from five cultures in Hong Kong and Venezuela.
Abstract: To broaden our conceptual framework for understanding cultural differences, the present article reports two studies that examined whether pancultural dimensions based on general beliefs, or social axioms, can be identified in persons from five cultures. A Social Axioms Survey was constructed, based on both previous psychological research primarily in Europe and North America on beliefs and qualitative research conducted in Hong Kong and Venezuela. Factor analyses of these beliefs from student as well as adult samples revealed a pancultural, five-factor structure, with dimensions labeled as: cynicism, social complexity, reward for application, spirituality, and fate control. In the second study, this five-factor structure, with the possible exception of fate control, was replicated with college students from Japan, the United States, and Germany. The potential implications of a universal, five-factor structure of individual social beliefs were discussed, along with the relation of this structure to indigen...

TL;DR: Leung et al. as mentioned in this paper revealed a five-dimensional structure of social axioms across individuals from five cultural groups across 41 nations and revealed the culture level factor structure and its correlates across 41 cultures.
Abstract: Leung and colleagues have revealed a five-dimensional structure of social axioms across individuals from five cultural groups. The present research was designed to reveal the culture level factor structure of social axioms and its correlates across 41 nations. An ecological factor analysis on the 60 items of the Social Axioms Survey extracted two factors: Dynamic Externality correlates with value measures tapping collectivism, hierarchy, and conservatism and with national indices indicative of lower social development. Societal Cynicism is less strongly and broadly correlated with previous values measures or other national indices and seems to define a novel cultural syndrome. Its national correlates suggest that it taps the cognitive component of a cultural constellation labeled maleficence, a cultural syndrome associated with a general mistrust of social systems and other people. Discussion focused on the meaning of these national level factors of beliefs and on their relationships with individual level factors of belief derived from the same data set.

TL;DR: Psychometric findings across diverse cultural context attest to the robustness of the P Scale and to positivity as a basic disposition.
Abstract: Five studies document the validity of a new 8-item scale designed to measure positivity, defined as the tendency to view life and experiences with a positive outlook. In the first study (N 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of college participants. In Study 2, the unidimensionality of the P Scale was corroborated with confirmatory factor analysis in 2 independent samples (N1 322; N2 457). In Study 3, P Scale invariance across sexes and its relations with self-esteem, life satisfaction, optimism, positive negative affect, depression, and the Big Five provided further evidence of the internal and construct validity of the new measure in a large community sample (N 3,589). In Study 4, test–retest reliability of the P Scale was found in a sample of college students (N 262) who were readministered the scale after 5 weeks. In Study 5, measurement invariance and construct validity of P Scale were further supported across samples in different countries and cultures, including Italy (N 689), the United States (N 1,187), Japan (N 281), and Spain (N 302). Psychometric findings across diverse cultural context attest to the robustness of the P Scale and to positivity as a basic disposition.

TL;DR: European Americans were found to be both more individualistic-valuing personal independence more-and less collectivistic-feeling duty to in-groups less-than others, and among Asians, only Chinese showed large effects, being both less individualistic and more collectivist.
Abstract: Are Americans more individualistic and less collectivistic than members of other groups? The authors summarize plausible psychological implications of individualism-collectivism (IND-COL), meta-analyze cross-national and within-United States IND-COL differences, and review evidence for effects of IND-COL on self-concept, well-being, cognition, and relationality. European Americans were found to be both more individualistic-valuing personal independence more-and less collectivistic-feeling duty to in-groups less-than others. However, European Americans were not more individualistic than African Americans, or Latinos, and not less collectivistic than Japanese or Koreans. Among Asians, only Chinese showed large effects, being both less individualistic and more collectivistic. Moderate IND-COL effects were found on self-concept and relationality, and large effects were found on attribution and cognitive style.

TL;DR: Evidence from a selection of research topics relevant to pandemics is discussed, including work on navigating threats, social and cultural influences on behaviour, science communication, moral decision-making, leadership, and stress and coping.
Abstract: The COVID-19 pandemic represents a massive global health crisis. Because the crisis requires large-scale behaviour change and places significant psychological burdens on individuals, insights from the social and behavioural sciences can be used to help align human behaviour with the recommendations of epidemiologists and public health experts. Here we discuss evidence from a selection of research topics relevant to pandemics, including work on navigating threats, social and cultural influences on behaviour, science communication, moral decision-making, leadership, and stress and coping. In each section, we note the nature and quality of prior research, including uncertainty and unsettled issues. We identify several insights for effective response to the COVID-19 pandemic and highlight important gaps researchers should move quickly to fill in the coming weeks and months.
