Guided by the early findings of social scientists, practitioners have long advocated for greater contact between groups to reduce prejudice and increase social cohesion. Recent work, however, suggests that intergroup contact can undermine support for social change towards greater equality, especially among disadvantaged group members. Using a large and heterogeneous dataset (12,997 individuals from 69 countries), we demonstrate that intergroup contact and support for social change towards greater equality are positively associated among members of advantaged groups (ethnic majorities and cis-heterosexuals) but negatively associated among disadvantaged groups (ethnic minorities and sexual and gender minorities). Specification curve analysis revealed important variation in the size-and at times, direction-of correlations, depending on how contact and support for social change were measured. This allowed us to identify one type of support for change-willingness to work in solidaritythat is positively associated with intergroup contact among both advantaged and disadvantaged group members.

The Black Lives Matter movement has drawn thousands of people to the streets to protest against the continued oppression of Black people. In many of these protests, Whites have joined Blacks in collective action for racial justice. What compels advantaged group members to engage in action on behalf of a disadvantaged group? A range of narratives suggests that the contact experiences members of advantaged groups have with members of disadvantaged groups can play an important role. Indeed, White historical figures such as

We examined whether people who are prone to believe COVID‐19 conspiracy theories are characterised by an especially strong concern for others or an especially strong concern for the self, and whether these orientations are associated with willingness to take a COVID‐19 vaccine. We surveyed 4,245 participants from eight nations; three months later we re‐contacted 1,262 participants from three nations. Belief in COVID‐19 conspiracy theories was related to greater concerns about one’s own safety, and lower concerns about the safety of close others. Furthermore, conspiracist ideation at Wave 1 predicted reluctance to take a COVID‐19 vaccine at Wave 2, mediated through relative concern for self versus other. In sum, people who are high in conspiracy beliefs have relatively higher concern for the self relative to others, with troubling implications for public health.

Our analysis explores the rise of the Yellow Vest movement as a collective response to perceptions of growing levels of economic inequality in France whereby collective action is triggered by the perceived illegitimacy of the growing gap between the 'haves' and 'have-nots'. We highlight different psychological processes that might explain why concerns about economic inequality have become more salient. We focus on two dynamics in particular: (a) President Macron's perceived alignment with the elites and disconnection from ordinary French people, and (b) historically dominant collective narratives that frame growing inequality as breaking with long-standing values and norms of equality. Both processes enhance 'us' (the victims) versus 'them' (the elite and those that are not true to national values of equality) categorizations along wealth lines whereby, 'us' becomes a broad category. To explain why the movement continues to go strong, we focus on ongoing intergroup processes (i.e., the police response, lack of support from intellectuals and the middle class) and intragroup processes (i.e., the movement brings together all those who self-categorise as victims of inequality, uniting those that may at other times be seen as 'strange bedfellows'). We conclude that a proper understanding of the way in which economic inequality might divide society creating new intergroup dynamics is essential to understand the Yellow Vest movement.
