Previous research has investigated the relationship between cultural values and leadership. This research expands on this tradition and examines how the strength of social norms—or tightness–looseness—influences perceptions of effective leadership. Data from Gelfand, Raver, et al. were integrated with GLOBE’s leadership research to examine the attributes of leaders seen as leading to effectiveness in tight and loose cultures. Analyses of data across 29 samples show that cultural tightness is positively related to the endorsement of autonomous leadership and negatively related to the endorsement of charismatic and team leadership, even controlling for in-group collectivism, power distance, and future orientation at the societal and organizational level of analysis. Theoretical and practical implications are discussed.
