Being in the minority boosts in-group love:Explanations and boundary conditions.

People appreciate members of their in-group, and they cooperate with them-tendencies we refer to as in-group love. Being a member of a minority (vs. majority) is a common experience that varies both between groups in a context and within a group between contexts, but how does it affect in-group love? Across six studies, we examined when and why .

Does communicating measurable diversity goals attract or repel historically marginalized job applicants? Evidence from the lab and field.

Many organizations struggle to attract a demographically diverse workforce. How does adding a measurable goal to a public diversity commitment-for example, "We care about diversity" versus "We care about diversity and plan to hire at least one woman or racial minority for every White man we hire"-impact application rates from women and racial minorities? Extant psychological theory offers competing predictions about how historically marginalized applicants might respond to such goals. On one hand, measurable diversity goals may raise belongingness concerns among marginalized group members who are uncomfortable with being recruited and hired based on their demographics.

When seeking help, women and racial/ethnic minorities benefit from explicitly stating their identity.

Receiving help can make or break a career, but women and racial/ethnic minorities do not always receive the support they seek. Across two audit experiments-one with politicians and another with students-as well as an online experiment (total n = 5,145), we test whether women and racial/ethnic minorities benefit from explicitly mentioning their demographic identity in requests for help, for example, by including statements like "As a Black woman…" in their communications. We propose that when a help seeker highlights their marginalized identity, it may activate prospective helpers' motivations to avoid prejudiced reactions and increase their willingness to provide support.

Megastudies improve the impact of applied behavioural science.

Policy-makers are increasingly turning to behavioural science for insights about how to improve citizens' decisions and outcomes. Typically, different scientists test different intervention ideas in different samples using different outcomes over different time intervals. The lack of comparability of such individual investigations limits their potential to inform policy.

Forgoing earned incentives to signal pure motives.

Policy makers, employers, and insurers often provide financial incentives to encourage citizens, employees, and customers to take actions that are good for them or for society (e.g., energy conservation, healthy living, safe driving).
