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.

Previous studies suggested that public trust in government is vital for implementations of social policies that rely on public's behavioural responses. This study examined associations of trust in government regarding COVID-19 control with recommended health behaviours and prosocial behaviours. Data from an international survey with representative samples (N=23,733) of 23 countries were analysed. Specification curve analysis showed that higher trust in government was significantly associated with higher adoption of health and prosocial behaviours in all reasonable specifications of multilevel linear models (median standardised β=0.173 and 0.244, P<0.001). We further used structural equation modelling to explore potential determinants of trust in government regarding pandemic control. Governments perceived as well organised, disseminating clear messages and knowledge on COVID-19, and perceived fairness were positively associated with trust in government (standardised β=0.358, 0.230, 0.055, and 0.250, P<0.01). These results highlighted the importance of trust in government in the control of COVID-19.

The mobilizing potential of the internet has been widely recognized but also sharply criticized. We propose and test in two studies that the social affirmation use of social media motivates individuals for collective action to achieve social change. In Study 1, we surveyed participants of a university occupation and found that enduring participation was predicted by social affirmation use, mediated by group identification. In Study 2 we experimentally tested our hypothesis, the results of which confirmed that the social affirmation use of a forum (and in particular its interactive aspect) motivated individuals for collective action to achieve social change. We discuss the theoretical and practical implications of our findings for theory and research on the mobilizing potential of the internet.

National and European policies aim to facilitate the integration of Roma people into mainstream society. Yet, Europe’s largest ethnic group continues to be severely discriminated. Although prejudice has been identified to be at the core of this failure, social psychological research on anti-Gypsyism remains scarce. We conducted a study in six countries using student and community samples ( N = 2,089; Hungary, Romania, Slovakia, Norway, Italy, Spain) to understand how anti-Gypsyism among majority-group members predicts unfavorable acculturation preferences toward Roma people. Openly negative stereotypes predicted acculturation preferences strongly across the countries. However, stereotypes about the Roma receiving undeserved benefits were also relevant to some degree in East-Central Europe, implying that intergroup relations are framed there as realistic conflict. Stereotypes about traditional Roma culture did not play a central role in acculturation preferences. Our findings highlighted that anti-Gypsyism may be an impediment to integration efforts, and efforts should be context-specific rather than pan-national.
