Collective nostalgia: Triggers and consequences for collective action intentions.

Global trends surveys suggest that collective nostalgia for one's country is widespread. Moreover, research indicates that collective nostalgia is used by populist radical-right parties to mobilize their voters against immigration. We focused on antecedents of collective nostalgia and its consequences for collective action in the context of national identity. In particular, we hypothesized that collective nostalgia for the country's past is triggered by a sense of collective discontinuity and subsequently engenders collective action intentions to protect the national ingroup and limit the presence of immigrant outgroups. We tested this hypothesis in a three-wave longitudinal cross-lagged panel study (N = 1489) among native Dutch majority members. The results were consistent with the hypothesis. The findings highlight the relevance of collective nostalgia as an emotional response to collective discontinuity that drives collective action intentions aimed at protecting ingroup continuity. We discuss implications of the findings for the literature on collective nostalgia and group dynamics as well as the broader literature on collective action and provide directions for future research.
