Ecological Threat and the Transmission of Cultural Tightness-Looseness

Previous research has shown cross-national and cross-regional variance in tightness-looseness, the strength of cultural norms and tolerance for deviance. This variance is reflected in cultural institutions like marriage, religiosity, politics, and has been related to ecological and historical factors. We explore how social and environmental threats (e.g. warfare, famine) influence tightness-looseness in traditional societies using the Standard Cross-Cultural Sample, and aHRAF World Cultures.
