Leftists and Rightists Differ in Their Cardiovascular Responses to Changing Public Opinion on Migration.

People may feel stressed when engaging with contentious topics, such as migration. However, when individuals learn that their opinion-based ingroup is growing or shrinking, they may experience this stress in different ways, namely as a threat or a challenge. In a preregistered study (N = 203 Dutch university students), we examined among host society members how progressive and conservative changes (vs.

Who values competent minds and who likes warm hearts? The role of right-wing authoritarianism and social dominance orientation in shaping voter preferences for political candidates.

Decades of research have recognized political candidates' competence and warmth as predictors of voter preferences, but to whom these distinct personalities are most appealing remains unclear. In the current research, we investigated how voters' Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) influenced their preferences for highly competent or warm political candidates. In two studies, we experimentally manipulated candidate competence (Study 1) and warmth (Study 2) and measured voter preferences using overall evaluations, the feeling thermometer, and the likelihood-of-voting rating.

"Who Islamises us?": Does political ideology moderate the effects of exposure to different Great Replacement Conspiracy explanations on radical collective action against different targets?

Conspiracy theories against outgroups (e.g., the Great Replacement Conspiracy [GRC]) are believed to fuel radicalisation.

How ingroup norms of multiculturalism (and tolerance) affect intergroup solidarity: The role of ideology.

Multiculturalism and tolerance, as two sets of normative beliefs about how to deal with intergroup diversity, have been recognized as effective at reducing outgroup negativity among majority group members. However, whether majority group members' normative beliefs regarding them might motivate their solidarity-based collective actions and how their political ideology might qualify this influence remained unclear. To answer these questions, we conducted two pre-registered experimental studies (N = 626), both zooming in on the multiculturalism issues in the context of the relationships between native Dutch citizens and citizens with a Moroccan background within Dutch university campuses (Study 1) and broader Dutch society (Study 2).

Economic Inequality Reduces Preferences for Competent Leaders.

It is well-documented that economic inequality can harm political stability and social cohesion. In six experiments (total = 1,907) conducted in China and the United Kingdom, we tested our primary hypothesis that high (vs. low) economic inequality leads to voters' reduced preferences for competent political leaders.

How epidemic information and policy information impact anti-infection behaviors: a cross-cultural study under social influence framing.

Three preregistered experiments examined to what extent information about an epidemic situation provided by experts and information about anti-infection policies promoted by governments/media influenced anti-infection behaviors. The above effects were examined among populations from different countries (in Experiments 2 and 3) and across self-construals (in Experiment 3). In three experiments, participants (N =706) were presented with a scenario where experts provided (or did not provide) information about an epidemic situation and governments/media promoted (or did not promote) information about anti-infection policies.
