Exploring social norms through a diversity perspective, this review examines whether minorities live in 'tighter' worlds, wherein they are subject to stricter rules and punishments. Integrating research from psychology, economics, and organizational behavior, we first examine whether minorities are more likely to have tightness imposed on them-i.e., receive more monitoring and harsher penalties in response to norm violations, compared to their majority counterparts. Turning to the subjective experience of minority group members, we explore whether minorities are calibrated to these penalties and experience greater lived tightness-the feeling of being chronically surveilled, judged harshly, and fearing excessive punishment for wrongdoing. We suggest that both imposed and lived tightness contributes to power inequalities and patterns of segregation. This framework helps to organize disparate research streams investigating minorities' experience of social norms, and highlights unanswered questions about when, and why, minority group members feel more constrained by social rules, as well as the consequences of these experiences for their economic and psychological wellbeing.
