A pervading global narrative suggests that political polarisation is increasing in the US and around the world. Beliefs in increased polarisation impact individual and group behaviours regardless of whether they are accurate or not. One driver of polarisation are beliefs about how members of the out-group perceive us, known as group meta-perceptions. A 2020 study by Lees and Cikara in US samples suggests that not only are out-group meta-perceptions highly inaccurate, but informing people of this inaccuracy reduces negative beliefs about the out-group. Given the importance of these findings for understanding and mitigating polarisation, it is essential to test to what extent they generalise to other countries. We assess that generalisability by replicating two of the original experiments in 10,207 participants from 26 countries in the first experiment and 10 in the second. We do this by studying local group divisions, which we refer to as fault lines. In line with our hypotheses, results show that the pattern found in the US broadly generalises, with greater heterogeneity explained by specific policies rather than between-country differences. The replication of a simple disclosure intervention in the second experiment yielded a modest reduction in negative motive attributions to the out-group, similar to the original study. These findings indicate first that inaccurate and negative group meta-perceptions are exhibited in a large number of countries, not only the US, and that informing individuals of their misperceptions can yield positive benefits for intergroup relations. The generalisability of these findings highlights a robust phenomenon with major implications for political discourse worldwide.

People are on the move in unprecedented numbers within and between countries. How does demographic change affect local intergroup dynamics? In complement to accounts that emphasize stereotypical features of groups as determinants of their treatment, we propose the group reference dependence hypothesis: violence and negative attitudes toward each minoritized group will depend on the number and size of other minoritized groups in a community. Specifically, as groups increase or decrease in rank in terms of their size (e.g., to largest minority within a community), discriminatory behavior and attitudes toward them should change accordingly. We test this hypothesis for hate crimes in U.S. counties between 1990 and 2010 and attitudes in the U.S. and U.K. over the last two decades. Consistent with this prediction, we find that, as Black, Hispanic/Latinx, Asian, and Arab populations increase in rank relative to one another, they become more likely to be targeted with hate crimes and more negative attitudes. The rank effect holds above and beyond group size/proportion, growth rate, and many other alternative explanations. This framework makes novel predictions about how demographic shifts may affect coalitional structures in the coming years and helps explain previous findings in the literature. Our results also indicate that attitudes and behaviors toward social categories are not intransigent or driven only by features associated with those groups, such as stereotypes.
