Three experiments tested the effects of threatening the social self in conjunction with self-linking on prejudice reduction. The Pilot Experiment demonstrated that threatening the social self was related to increased expressions of prejudice. It also demonstrated that expressing prejudice was a way in which the social self could be partially…

Two studies examined the role of temporal-based social categorizations for attitude change during intergroup contact between Polish and Jewish students. In Study 1 (N = 190 Polish students), a cross-sectional analysis showed that contact focused on contemporary issues had positive effects on both outgroup attitudes and perceived…

This study investigated the intensity of homophobia related to its ability to be changed. Homophobia was assessed using the Modified Index of Homophobia (IHP-M). The effects of a videotape containing educational and emotionally persuasive material on homophobia was investigated. The relationships between individuals' degree of homophobia, their…

Three studies, conducted in the Netherlands, examined the relationship between a tolerant representation of national history and the acceptance of Muslim expressive rights. Following self-categorization theory, it was hypothesized that historical tolerance would be associated with greater acceptance of Muslim expressive rights, especially for…

When conceiving diversity training—a popular strategy to manage prejudice within organizations and educational settings—there is little reliance on social–psychological theorizing and a lack of research on training effectiveness. In line with the ingroup projection model (Mummendey & Wenzel, 1999), we postulate diversity training to improve…

This experiment examined the hypothesis derived from the social categorization perspective that intergroup cooperation reduces bias by transforming members' cognitive representations of the aggregate from 2 groups to 1 group. Two 3-person groups experienced intergroup contact under conditions that varied (a) member's representations of the…

This experiment examined the effectiveness of one-group and dual-identity recategorization strategies on reducing intergroup bias among 180 European Portuguese and African Portuguese 9- and 10-year-old children. Results revealed that each of these recategorization strategies, relative to one that emphasized separate group identities, was…

This article assesses the mechanisms whereby first-person narratives featuring stigmatized immigrants improve outgroup attitudes and encourage intergroup contact among prejudiced individuals. We rely on a 2 (imagined contact vs. control) × 2 (similar vs. dissimilar message protagonist) experiment on a systematic sample of native…

Previous research indicates that meta -stereotypes are predominantly negative. However, the valence of the meta -stereotypes may not be the only factor accounting for the detrimental effects associated with their activation. In addition to valence, we propose that the subjective difficulty of retrieving the meta -stereotype might critically…

Understanding the underpinnings of climate justice, especially justice in carbon allocation, is paramount for international cooperation in coping with climate change. Previous work has attempted to promote carbon allocation justice based on a utilitarian theory of justice, but it has backfired. Adopting the per capita approach in defining…
