We exploit a policy designed to randomly allocate roommates in a large South African university to investigate whether inter-racial interaction affects stereotypes, attitudes and performance. Using Implicit Association Tests, we find that living with a roommate of a different race reduces white students' negative stereotypes towards black ones…

Stigma associated with gambling disorder is complex, and is a key obstacle that prevents sufferers from seeking early help for their condition. However, little research has addressed how best to reduce gambling stigma. This study explored the effectiveness of video intervention styles, that have been used to reduce public stigma for conditions…

Individuals with obesity often report experiencing prejudice and discrimination due to their weight. Past research on obesity bias reduction strategies have yielded mixed results. The present study investigated the effectiveness of manipulating information about weight controllability in reducing obesity bias. Participants (N = 350) were…

One of the key factors contributing to the development of negative attitudes toward out-groups is lack of knowledge about them. The present study investigated what type of information 3- to 4- and 5- to 6- year-old Jewish Israeli children (N = 82) are interested in acquiring about unfamiliar in- and out-group individuals, and how providing…

In this experiment, we examined the effect of perspective-taking—actively contemplating others’ psychological experiences—on linguistic intergroup bias. We asked some participants to adopt the perspective of a character (an Italian or a Maghrebian), while others did not receive similar instructions, and complete a short dialogue comprised of a…

The current studies aimed to reveal the potential role of imagined intergroup contact on collective action tendencies within a context of intergroup conflict. Study 1 (disadvantaged Kurds, N = 80) showed that imagined contact increased collective action tendencies and this effect was mediated by increased perceived discrimination and ethnic…

We examined the effectiveness of an imagery-based strategy designed to reduce prejudice in preschoolers in Italy. Three studies involving different target groups (disabled children, Black children) were conducted within Italian preschools. Children (4–6 years) were asked to imagine and draw meeting an outgroup member (Studies 1 and 2) or…

We investigated whether confrontations of intergroup bias that had an external (e.g., emphasizing social norms) versus internal (e.g., emphasizing values) motivational framing differentially reduced subsequent stereotyping. Internally and externally framed confrontations reduced stereotyping equally compared to a control condition, both…

We present results from a large (n = 3,016) field experiment at a global organization testing whether a brief science-based online diversity training can change attitudes and behaviors toward women in the workplace. Our preregistered field experiment included an active placebo control and measured participants’ attitudes and real…
