Populist Attitudes Predict Compliance-Related Attitudes and Behaviors During the COVID-19 Pandemic Via Trust in Institutions

While previous research discussed populism as a phenomenon of declining trust, we investigated the predictive value of populist attitudes for citizens’ trust, attitudes, and behaviors during the COVID-19 pandemic. Moreover, we tested the role of trust in several institutions simultaneously. As preregistered, the cross-sectional ( N = 1,090) and longitudinal ( n = 216) data collected (April to June, 2020) in Germany ( n = 617) and Poland ( n = 473) showed that stronger populist attitudes predicted higher trust in (a) alternative news media but less trust in (b) mainstream news media, (c) political institutions, and (d) scientific institutions. Moreover, we found negative effects of populist attitudes on acceptance and compliance, mediated via trust in political and scientific institutions (but not news media)

A double‐edged sword: How social diversity affects trust in representatives via perceived competence and warmth

Abstract Previous research has claimed that diversity erodes trust, even though the empirical evidence is mixed and restricted to ethnic neighborhood diversity. Against the backdrop of increasing diversity within the political sphere and concurrently declining political trust, we examined the impact of social diversity on trust in groups of political representatives. In two experiments (N1 = 109, N2 = 248) we tested how the diversity of political parties affected citizens’ trust in them. In line with predictions of the stereotype content model, diverse parties were perceived as warmer and less competent than non‐diverse parties (Experiments 1–2). Additionally, party diversity was perceived as having more benefits, but also involving more threats (Experiment 2). Consequently, diversity had both positive (via warmth and benefits) and negative (via competence and threats) indirect effects on trust. These results help to untangle previously mixed, for the most part non‐experimental, findings of the relationship between diversity and trust

When does activating diversity alleviate, when does it increase intergroup bias?: An ingroup projection perspective

The question how intergroup bias can be alleviated is of much theoretical and practical interest. Whereas diversity training and the multiculturalism ideology are two approaches prominent in practice, most theoretical models on reducing intergroup bias are based on social-identity theory and self-categorization theory. This social-identity perspective assumes that similar processes lead to intergroup bias in very different intergroup contexts if people identify with the respective social groups. A recent prominent model based on these theories is the ingroup-projection model. As this model assumes, an ingroup's norms and standards are applied to outgroups included in a common superordinate category (this is called ingroup projection). Intergroup bias results because the outgroup fulfils these norms and standards less than the ingroup. Importantly, if the diversity of the superordinate category is induced as the norm, ingroup projection and thus intergroup bias should be reduced. The present research delineates and tests how general this process is. We propose that ingroup prototypicality is not only an outcome variable, as the ingroup-projection model originally assumes, but can also be an important moderator. We hypothesize that for members considering their ingroup highly prototypical ("pars pro toto", large majorities), the superordinate group's diversity may question their ingroup's position and thus elicit threat and intergroup bias. In contrast, for members who consider their group as less prototypical (one among several, or "una inter pares" groups), activating diversity should, as originally assumed in the ingroup-projection model, reduce intergroup bias. Three experiments (total N = 345) supported these predictions in the contexts of groups defined by gender or nationality. Taken together, the ingroup-projection model can explain under which conditions activating superordinate-category diversity induces tolerance, and when it may backfire. We discuss in how far the ingroup-projection model can integrate conflicting findings on the multiculturalism ideology
