HEXACO Personality Factors and their Associations with Facebook use and Facebook Network Characteristics.

Personality factors affect the properties of 'offline' social networks, but how they are associated with the structural properties of online networks is still unclear. We investigated how the six HEXACO personality factors (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness and Openness to Experience) relate to Facebook use and three objectively measured Facebook network characteristics - network size, density, and number of clusters. Participants (n = 107, mean age = 20.6, 66% female) extracted their Facebook networks using the GetNet app, completed the 60-item HEXACO questionnaire and the Facebook Usage Questionnaire. Users high in Openness to Experience spent less time on Facebook. Extraversion was positively associated with network size (number of Facebook Friends). These findings suggest that some personality factors are associated with Facebook use and the size of Facebook networks, and that personality is an important influence on both online and offline sociality.

Highlighting health consequences of racial disparities sparks support for action.

Racial disparities arise across many vital areas of American life, including employment, health, and interpersonal treatment. For example, one in three Black children lives in poverty (versus one in nine white children), and, on average, Black Americans live four fewer years compared with white Americans. Which disparity is more likely to spark reduction efforts? We find that highlighting disparities in health-related (versus economic) outcomes spurs greater social media engagement and support for disparity-mitigating policy. Further, reading about racial health disparities elicits greater support for action (e.g., protesting) compared with economic- or belonging-based disparities. This occurs in part because people view health disparities as violating morally sacred values, which enhances perceived injustice. This work elucidates which manifestations of racial inequality are most likely to prompt Americans to action.

Acting for whom, against what? Group membership and multiple paths to engagement in social change.

In a connected and politically engaged world, it is essential to understand how, why, and when people from diverse backgrounds may support social action. Integrating findings from the collective action, solidarity, and allyship literatures, we present working models of how the lenses through which individuals possessing different group memberships may psychologically identify (as part of the targeted group, an inclusive stigmatized identity, or the societally dominant group) and perceive injustice (as exclusively affecting the targeted group, inclusively affecting the target group and one's ingroup, or perceiving ingroup privileges) may shape social change efforts. We highlight disparate effects of positive (and negative) contact between groups on the mobilization of socially dominant and stigmatized groups that may provide challenges to diverse coalitions seeking social change.

Intergroup Inequality Heightens Reports of Discrimination Along Alternative Identity Dimensions.

How do members of societally valued (dominant) groups respond when considering inequality? Prior research suggests that salient inequality may be viewed as a threat to dominant-group members' self and collective moral character. However, people possess multiple social identities and may be advantaged in one domain (e.g., White) while concurrently disadvantaged in another domain (e.g., sexual minority). The present research tests whether individuals may reduce the moral-image threat of being societally advantaged in one domain by highlighting discrimination they face in other domains. Four experiments with individuals advantaged along different dimensions of inequality (race, social class, sexuality) reveal that making such inequality salient evokes greater perceived discrimination faced by oneself and one's ingroups along other identity dimensions.
