The special issue we edited for the INCLUSIVITY project, "The Impact of Social Norms on Cohesion and (De)Polarization", is now out in the journal Social Inclusion. In a time of increasing polarization, this issue seeks to address whether social norms can help shape intergroup dynamics in polarized contexts, and if so, if we can intervene in them to counter polarization. The issue was edited by Miranda Lubbers, Marcin Bukowski, Oliver Christ, Eva Jaspers, and Maarten van Zalk, the PIs of the INCLUSIVITY project. It features 12 papers, written by authors from Germany, the Netherlands, Poland, and Spain. They explore four central themes: (a) the role of social norms in fostering tolerance and depolarization; (b) the association between norm deviations and non‐normative behaviors and political polarization; (c) the negotiation versus contestation of social norms by competing groups; and (d) the influence of social networks on intergroup attitudes and behaviors that can facilitate depolarization processes. We are happy with how the special issue turned out and we hope you like it!
