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.

This study sought to identify the effects of culture and sex on mate preferences using samples drawn world-wide. Thirty-seven samples were obtained from 33 countries located on six continents and five islands (N = 9,474). Hierarchical multiple regressions revealed strong effects of both culture and sex, moderated by specific mate characteristics. Chastity proved to be the mate characteristic on which cultures varied the most. The preference ordering of each sample was contrasted with an international complement. Each culture displayed a unique preference ordering, but there were some similarities among all cultures as reflected in a positive manifold of the cross-country correlation matrix. Multidimensional scaling of the cultures yielded a five dimensional solution, the first two of which were interpreted. The first dimension was interpreted as Traditional versus Modern, with China, India, Iran, and Nigeria anchoring one end and the Netherlands, Great Britain, Finland, and Sweden anchoring the other. The second dimension involved valuation of education, intelligence, and refinement. Consistent sex differences in value attached to eaming potential and physical attractiveness supported evolution-based hypotheses about the importance of resources and reproductive value in mates. Discussion emphasizes the importance of psychological mate preferences for scientific disciplines ranging from evolutionary biology to sociology.

The dimension of individualism‐collectivism, as identified by Hofstede (1980), was studied using items developed both theoretically and emically in nine diverse cultures. The dimension was found to be analysable into four stable etic factors: Individualism had two aspects (Separation from Ingroups and Self‐Reliance with Hedonism) and collectivism had two aspects (Family Integrity and Interdependence with Sociability). These four factors are orthogonal to each other. The location of nine cultures on these four factors was used to compute a “collectivism” score which correlated r = + · 73 with Hofstede's (1980) collectivism scores for the nine cultures. This approach enables the measurement of individualism‐collectivism in each culture as well as across cultures, and shows that different methods for measuring individualism‐collectivism converge.

Relationships between context variables (ecosocial indices) and psychological variables across different nations were investigated, guided by Berry’s Ecocultural Framework. The psychological variables were values (Hofstede; Inglehart; Schwartz; Smith, Dugan, and Trompenaars) and subjective well-being (Diener). The ecosocial indices of religion and affluence had separate and in some ways contrasting relationships with psychological variables. Some religions were related to higher interpersonal power, loyalty, and hierarchy, but lower affluence. Other religions, (particularly Protestantism) and higher affluence were related to intrapersonal aspects, such as individualism, utilitarian commitment, and well-being. The most important result was the finding that scores of psychological variables showed systematic relationships with cluster membership of countries on ecosocial indices. The study proposes a solution to a theoretical and methodological problem of current cross-cultural psychology: the search for cultural (context) variables that would explain similarities and differences in psychological variables in different clusters of countries.
