Variety Is the Spice of Life: Diverse Social Networks Are Associated With Social Cohesion and Well-Being.

Both homophily and heterophily are observed in humans. Homophily reinforces homogeneous social networks, and heterophily creates new experiences and collaborations. However, at the extremes, high levels of homophily can cultivate prejudice toward out-groups, whereas high levels of heterophily can weaken in-group support. Using data from 24,726 adults (M = 46 years; selected from 10,398 English neighborhoods) and the composition of their social networks based on age, ethnicity, income, and education, we tested the hypothesis that a middle ground between homophily and heterophily could be the most beneficial for individuals. We found that network homophily, mediated by perceived social cohesion, is associated with higher levels of subjective well-being but that there are diminishing returns, because at a certain point increasing network homophily is associated with lower social cohesion and, in turn, lower subjective well-being. Our results suggest that building diverse social networks provides benefits that cannot be attained by homogeneous networks.

Positive and negative intergroup contact and newcomer immigrants' psychological adjustment.

OBJECTIVES: The present research investigates the associations between immigrants' positive and negative contact with the majority group and their psychological well-being, as indicators of their psychosocial adjustment to the host society. Perceived personal discrimination and relative deprivation in comparison to the majority group are assessed as mediators of the associations between intergroup contact and psychological well-being. METHOD: We conducted a three-wave longitudinal study with newcomer African immigrants living in Italy (N = 240; 61.7% men) with age ranging from 18 to 40 years old. RESULTS: Evidence showed that, across three waves, immigrants' negative contact with Italian natives was longitudinally associated with lower well-being and positive intergroup contact. In turn, well-being was related to immigrants' lower perceptions of relative deprivation across waves. Positive contact with Italian natives was not significantly associated with immigrants' well-being, but it was associated with higher perceived relative deprivation, which was associated with lower well-being. CONCLUSIONS: Overall, the results provide insight into the links between differently valenced contact and the psychological well-being of newcomer immigrants. Furthermore, the findings address assumptions about the primacy of negative contact in undermining social attitudes and the important role of positive contact in promoting awareness of the disadvantaged group's situation.

Intergroup contact is reliably associated with reduced prejudice, even in the face of group threat and discrimination.

Intergroup contact provides a reliable means of reducing prejudice. Yet, critics suggested that its efficacy is undermined, even eliminated, under certain conditions. Specifically, contact may be ineffective in the face of threat, especially to (historically) advantaged groups, and discrimination, experienced especially by (historically) disadvantaged groups. We considered perceived intergroup threat and perceived discrimination as potential moderators of the effect of contact on prejudice. Two meta-analyses of correlational data from 34 studies (totaling 63,945 respondents-drawn from 67 subsamples across 19 countries) showed that contact was associated with decreased prejudice and increased out-group positivity, in cross-sectional and longitudinal designs, among advantaged and disadvantaged group members, and in both Western, Educated, Industrialized, Rich, and Democratic (WEIRD) and non-WEIRD contexts. Both perceived threat and perceived discrimination moderated the contact-attitude association, but in an unanticipated direction. Indeed, contact's beneficial effects were at least as strong among individuals high (r = .19) as among individuals low (r = .18) in perceived threat. Similarly, the effects of contact were at least as strong among those high (r = .23) as among those low (r = .20) in perceived discrimination. We conclude that contact is effective for promoting tolerant societies because it is effective even among subpopulations where achieving that goal might be most challenging.

Effects of intergroup contact on explicit and implicit outgroup attitudes: A longitudinal field study with majority and minority group members.

A longitudinal field study tested the long-term effects (three years) of intergroup contact on both explicit and implicit outgroup attitudes. Participants were majority (Italian) and minority (immigrant) high-school students, who were tested at four waves from the beginning of their first year in high-school to the end of the third school year. Results revealed, first, a longitudinal association of quantity (but not quality) of contact with lower intergroup anxiety and more positive explicit attitudes, as well as bidirectional effects over time between explicit attitudes and intergroup anxiety, on the one hand, and quantity and quality of contact, on the other. Second, reduced intergroup anxiety mediated the association between quantity of contact and improved explicit attitudes over time. Third, the product of quantity and quality of contact longitudinally predicted more positive implicit outgroup attitudes over school years. We discuss the theoretical and practical implications of findings.

Antecedents of positive and negative intergroup contact: Evidence from a diary study.

In our current globalised, multicultural world, understanding antecedents of reciprocal interactions between native people and people of immigrant background is a major issue, because intergroup contact plays a crucial role in building inclusive societies. In this vein, using daily diary data, we examined the relation between the number of daily positive and negative interactions of White British majority (N = 744) and Asian British minority people (N = 582) with members of the respective outgroup, with RWA, SDO, perceived ingroup norms, neighbourhood diversity and contextual deprivation. Results showed that for the majority group, ingroup norms in favour of intergroup contact were positively associated with positive intergroup encounters, whereas Right Wing Authoritarianism (RWA) was positively associated with negative intergroup contact. Neighbourhood diversity was positively associated with positive and negative intergroup encounters. Moreover, RWA moderated the relationship between neighbourhood diversity and both positive and negative contact of White British people. For the minority group, ingroup norms were positively associated with positive intergroup contact, and the relationship between ingroup norms and negative contact was moderated by SDO. Overall, different factors affect positive and negative intergroup contact of majority and minority groups. We discuss the implications of the findings for future research and interventions.

Seeking and avoiding contact with Muslims at a Hijab Stall: Evidence for multilayer, multi-determined solidarity, courage, apathy, and moral outrage.

Intergroup contact is key to social cohesion, yet psychological barriers block engagement with diversity even when contact opportunities are abundant. We lack an advanced understanding of contact seeking because intergroup contact is often an independent variable in research, and studies on contact seeking have favoured experimental probing of selected factors or measured only broad behavioural intentions. This research carried out the first ecological tests of a novel multilayer-multivariate framework to contact seeking/avoiding. These tests were centred on a Muslim-led community contact-based initiative with visible support from local authorities following a terrorist attack. Non-Muslim Australian women (N = 1,347) contributed field data on their situated contact motivations, choices, and attendance at an intercultural educational stall; many (N = 559) completed a profiling test battery. Among those who responded to the initiative invite, the rate of taking up the high-salience contact opportunity in this heated setting was high and reflected multiple approach/avoidance motivations. Contact seeking/avoiding was not just allophilia/prejudice; it presented as new typologies of politicized solidarity, courage, apathy, and moral outrage. While intergroup predictors were significant across all profiling analyses, intrapersonal and interpersonal predictors also regularly contributed to explain variance in non-Muslims' contact motivations and choices, confirming their multilayer-multivariate nature.

Dynamic contact effects: Individuals' positive and negative contact history influences intergroup contact effects in a behavioral game.

Positive contact between members of different groups reduces prejudice and increases cooperation, findings known as intergroup contact effects. Yet in real-world settings not only positive, but also negative intergroup contact occurs, which have opposing effects. To date little is known about whether and how an individual's valenced history of intergroup contact influences contact effects and how this dynamic change happens during specific instances of intergroup contact. A pilot study examined the psychological impact of a novel paradigm to assess intergroup contact using a behavioral game. We then conducted two studies, which allowed us to observe a sequence of up to 23 in- and outgroup interactions and their behavioral outcomes in a continuous prisoner's dilemma behavioral game (N = 116, 2,668 interactions; N = 89, 1,513 interactions). As expected, participants showed a clear ingroup bias in expectations and cooperation. Furthermore, the quality of contact history moderated contact effects. Specifically, intergroup contact following a positive history of intergroup contact had a stronger effect on intergroup expectations than contact following a negative history thereof. Findings are discussed in view of the importance of considering the valenced history of intergroup contact, as well as new research questions on intergroup contact that can be addressed with this novel contact paradigm.

Disentangling contact and socialization effects on outgroup attitudes in diverse friendship networks.

Friendships with members of our own group (ingroup) and other groups (outgroups) shape our attitudes toward outgroups. Research on intergroup contact has shown that the numbers of outgroup and ingroup friends we have influence our outgroup attitudes, whereas research on socialization has shown that the attitudes held by our friends influence our outgroup attitudes. Past research, however, examined these processes in isolation, which precludes discerning whether having friends, or the attitudes held by our friends, are both important in shaping our outgroup attitudes, and, if so, which is more important. To disentangle these effects, we conducted a 5-wave social network study in 2 ethnically diverse schools (N = 1,170 students). By applying a novel longitudinal coevolution model, we were able to separate the effects of having ingroup and outgroup friends (contact effects), and the effects of those friends' attitudes (socialization effects), on individuals' outgroup attitudes, while controlling for friendship selection processes. In so doing, we found that it is principally the attitudes of ingroup friends-not outgroup friends' attitudes or having ingroup and outgroup friends alone-that predict individuals' outgroup attitudes. Our findings have important theoretical implications, as we demonstrate that combining the divergent approaches of intergroup contact and socialization enables us to better understand outgroup attitude development. Our findings also have practical implications, as we show that, even in diverse environments, individuals rely primarily on friends from their own group to inform their attitudes toward other groups.

Shared education as a contact-based intervention to improve intergroup relations among adolescents in postconflict Northern Ireland.

Past research has shown that intergroup contact can be a promising intervention to improve intergroup relations and that contact-based interventions might be most effective during adolescence. In postconflict Northern Ireland, widespread residential segregation and a largely separate school system limit opportunities for intergroup contact between adolescents from the Catholic and Protestant communities. We evaluated whether a large-scale intervention to facilitate intergroup contact between students attending separate schools (the 'Shared Education' program) improves a range of outcomes relevant for intergroup relations in Northern Ireland. We conducted a 5-wave longitudinal, quasi-experimental study that followed a large sample of school students (N = 5,159, Mage = 12.4, age range: 10-14 years; 2,988 girls, 2,044 boys) from 56 predominantly Catholic or Protestant schools from sixth to tenth grade. We compared the developmental trajectories of students who, in 9th (14-15 years) and 10th (15-16 years) grade, shared some classes with students from the other community, as part of the program, to students who did not. We found that participating in shared classes had a medium-size, positive effect on the amount of intergroup contact students had outside of class, and small, positive effects on students' outgroup attitudes, outgroup trust, and intergroup empathy (but not on their intergroup anxiety, future contact intentions, deprovincialization, or multicultural beliefs). Our findings show that a school-based program of shared education can provide a viable and effective intervention to facilitate intergroup contact, improve intergroup relations, and foster social integration among adolescents at a large scale in a postconflict society.

Adolescent development of interethnic attitudes following a social intervention to increase intergroup contact: The moderating role of affective forecasting.

This longitudinal, quasi-experimental field study investigated affective forecasting as a moderator of positive intergroup contact effects among adolescents. We also examined a novel mediating mechanism that underlies this effect, namely accuracy of perceived outgroup willingness for intergroup contact. Three annual waves of survey data were used from 1,169 adolescents (Mage = 13.88 at Wave 1; 50% girls; 66% White British, 44% Asian British) whose schools were merged, in a unique intervention that resulted in one school where ethnic groups were evenly mixed (i.e., balanced school) and two White British majority schools (i.e., majority skewed schools). Results showed that positive intergroup contact and attitudes improved more in the balanced school than in the majority skewed schools. In all schools, change in adolescents' positive intergroup contact predicted change in positive intergroup attitudes indirectly via (a) increased accuracy of perceived outgroup willingness for contact and (b) reduced intergroup anxiety. Indirect effects via accuracy of perceived contact willingness were stronger for adolescents who made more negative affective forecasts than for other adolescents. These moderated mediation effects were stronger in the balanced school than in the majority skewed schools. Thus, more balanced ethnic mixing in schools seemed to directly enhance positive intergroup relations and attitudes for all adolescents, but to particularly benefit adolescents who made more negative affective forecasts about positive contact before the school merger.

Building Social Cohesion Through Intergroup Contact: Evaluation of a Large-Scale Intervention to Improve Intergroup Relations Among Adolescents.

Past research has found intergroup contact to be a promising intervention to reduce prejudice and has identified adolescence as the developmental period during which intergroup contact is most effective. Few studies, however, have tested whether contact-based interventions can be scaled up to improve intergroup relations at a large scale. The present research evaluated whether and when the National Citizen Service, a large-scale contact-based intervention reaching one in six 15- to 17-year-olds in England and Northern Ireland, builds social cohesion among adolescents from different ethnic backgrounds. In a diverse sample of adolescents (N = 2099; Mage = 16.37, age range: 15-17 years; 58% female), this study used a pretest-posttest design with a double pretest to assess the intervention's effectiveness. Controlling for test-retest effects, this study found evidence that the intervention decreased intergroup anxiety and increased outgroup perspective-taking-but not that it affected intergroup attitudes, intergroup trust, or perceptions of relative (dis-)advantage. These (small) effects were greater for adolescents who had experienced less positive contact before participating and who talked more about group differences while participating. These findings suggest that the intervention might not immediately improve intergroup relations-but that it has the potential to prepare adolescents, especially those with less positive contact experiences before the intervention, for more positive intergroup interactions in the future.

Does ethnic diversity affect well-being and allostatic load among people across neighbourhoods in England?

Modern societies are facing unprecedented changes in their ethnic composition. Increasing ethnic diversity poses critical new challenges as people interact with new cultures, norms, and values, or avoid such encounters. Heated academic and political debates focus on whether and how changes in ethnic composition affect societies and local communities. Yet, there is insufficient scientific evidence of how living in a more diverse society affects individuals' well-being and health. The aim of this study is to test the extent to which increasing neighbourhood ethnic diversity affects individuals' subjective health and well-being and objective stress levels as measured by allostatic load. We analyse a large panel data set containing over 47,000 English respondents living in 15,545 neighbourhoods in England from the British Household Panel Survey and the UK Household Longitudinal Study, from 2004 to 2011. We match respondents to neighbourhoods and merge contextual information about levels of neighbourhood ethnic diversity and deprivation from UK Censuses, whilst controlling for background characteristics. We distinguish between short- and long-term effects of ethnic diversity on individual subjective well-being and health as well as allostatic load using a set of multilevel mixed-effects models. We make cautious causal interpretations by estimating fixed-effects models and cross-lagged panel models. We assess the robustness of our findings by replicating our analysis using alternative composite measures of diversity and allostatic load. In the short-term, increasing ethnic diversity of local areas is associated with a dip in subjective well-being, but short-term changes are not prolonged or profound enough to affect chronic stress (allostatic load). The initial negative impact of ethnic diversity on subjective well-being and health dissipates with time. In the long-term, no effects of ethnic diversity on well-being and health or chronic stress (allostatic load) are detected. Understanding the dynamic nature of the effects of ethnic diversity on individuals has critical implications for social and public health policies - issues prominent in, for example, the UK (Brexit) and the US (election of President Donald Trump). Our analysis identifies and enables the promotion of beneficial effects, while targeting the pernicious components to turn diversity into a valuable asset in a globalising world.

COVID-19 threat and perceptions of common belonging with outgroups: The roles of prejudice-related individual differences and intergroup contact.

COVID-19 represents a multidimensional threat with the potential to worsen intergroup relations, but perceiving a common belonging with various outgroups may prevent intergroup tensions. During the Italian lockdown, we conducted an online survey with 685 Italian participants investigating whether perceptions of common belonging (belonging to a common group, sharing a common destiny, perceiving the difficulties faced by other groups) with disadvantaged and national outgroups were associated with perceived COVID-19 threat and prejudice-related individual differences, namely social dominance orientation (SDO), need for cognitive closure (NFC), deprovincialization, pre-lockdown positive and negative face-to-face contact with immigrants. We also explored the moderating roles of individual differences in the link between perceived threat and perceptions of common belonging. Results showed that common belonging was negatively associated with COVID-19 perceived threat, SDO, and NFC, and positively associated with deprovincialization and positive contact, with differences depending on the common belonging index and on the type of outgroup. Moderations showed that negative relationships between common belonging and COVID-19 threat held only at low levels of NFC (floor effect), deprovincialization, and positive contact. Summarizing, positive contact with minorities and openness to other cultures can favor a sense of communion with other social groups in a global health emergency.

Using Longitudinal Social Network Analysis to Evaluate a Community-Wide Parenting Intervention.

Harsh parenting attitudes and behaviors negatively impact children's behavior and development, and are linked to heightened levels of violence in children. Parent training programs are effective preventive interventions, but only reach caregivers who attend them. In this study, programs were implemented alongside a community mobilization process, intended to use caregivers' social networks to disseminate new parenting skills community wide. We used social network analysis to explore whether this intervention, first, increased positive parenting, second, changed social networks of female caregivers (selection), and, third, influenced parenting behavior via connections (socialization), while controlling for psychiatric morbidity, parenting stress, alcohol misuse, and child's age. "Colored" Afrikaans-speaking female caregivers (N = 235; mean age 35.92 years) in a rural community in South Africa, with children between 1½ and 18 years old, were included in the study; two waves of data were collected (January-April 2016 and June-October 2017). We detected community-wide increases in positive parenting behavior (involvement, supervision, consistent discipline, and reduced corporal punishment). Attending at least one session of a parenting skills training program (n = 51; 21.7%) significantly predicted increases in network centrality (i.e., outdegree and indegree). Caregivers appeared to use similar parenting behavior to other caregivers they were connected to within the network, especially when those others attended a parenting skills training program. Overall, the results suggest that the information in the intervention was spread throughout the community through social interactions with program attendees and the community mobilization process. The results also illustrate the value of social network analysis for ascertaining the processes by which the intervention achieved its impact.

Overlap in processing advantages for minimal ingroups and the self.

Cognitive biases shape our perception of the world and our interactions with other people. Information related to the self and our social ingroups is prioritised for cognitive processing and can therefore form some of these key biases. However, ingroup biases may be elicited not only for established social groups, but also for minimal groups assigned by novel or random social categorisation. Moreover, whether these 'ingroup biases' are related to self-processing is unknown. Across three experiments, we utilised a social associative matching paradigm to examine whether the cognitive mechanisms underpinning the effects of minimal groups overlapped with those that prioritise the self, and whether minimal group allocation causes early processing advantages. We found significant advantages in response time and sensitivity (dprime) for stimuli associated with newly-assigned ingroups. Further, self-biases and ingroup-biases were positively correlated across individuals (Experiments 1 and 3). However, when the task was such that ingroup and self associations competed, only the self-advantage was detected (Experiment 2). These results demonstrate that even random group allocation quickly captures attention and enhances processing. Positive correlations between the self- and ingroup-biases suggest a common cognitive mechanism across individuals. These findings have implications for understanding how social biases filter our perception of the world.

Dual Identity Development and Adjustment in Muslim Minority Adolescents.

Dual identity (e.g., strong ethnic and national identity) is a psychological resource for minority groups, but how it develops during adolescence is less clear. In this 3-wave longitudinal study, a person-oriented approach was used to examine dual identity development in a sample of 2145 Muslim adolescents (MT1 = 15 years, 51% female) in four Western European countries. The results of a growth-mixture model pointed toward four distinct developmental Classes: (1) "Dual identity", (2) "Separation to dual identity", (3) "Assimilation to dual identity", and (4) "Separation". Multiple group comparisons further showed that adolescents in Class 1 were well adjusted, but well-being (e.g., internalizing problems, life satisfaction) and health were even higher among adolescents in Class 2. Adolescents in Class 3 had consistently lower levels of well-being, and adolescents in Class 4 had lower levels of socio-cultural adjustment (e.g., problem behaviour at school, delinquent behaviour, and lack of intergroup contact). The findings underscore that most Muslim minority adolescents in Western Europe develop a dual identity, and that the developmental process, not simply the outcome, matters for adjustment.

Humans adapt to social diversity over time.

Humans have evolved cognitive processes favoring homogeneity, stability, and structure. These processes are, however, incompatible with a socially diverse world, raising wide academic and political concern about the future of modern societies. With data comprising 22 y of religious diversity worldwide, we show across multiple surveys that humans are inclined to react negatively to threats to homogeneity (i.e., changes in diversity are associated with lower self-reported quality of life, explained by a decrease in trust in others) in the short term. However, these negative outcomes are compensated in the long term by the beneficial influence of intergroup contact, which alleviates initial negative influences. This research advances knowledge that can foster peaceful coexistence in a new era defined by globalization and a socially diverse future.

Immigration, social trust, and the moderating role of value contexts.

This study examines whether the values prevalent in one's social environment moderate the link between immigration-related ethnic diversity and social trust. Drawing on arguments related to intergroup relations and anomie, we expect that contexts characterized by a comparatively high degree of openness mitigate a trust-eroding effect of immigration. In contrast, we expect that contexts of low openness or high conservation may reinforce a trust-eroding effect. We test these propositions using survey data from Europe and the United States merged with regional indicators on immigration and value contexts. The results show that high levels of contextual openness attenuate trust-eroding consequences of immigration growth. With regard to mechanisms, we find that contextual openness moderates how change in immigration relates to generalized forms of trust rather than outgroup trust. This points to an overall anomie-reducing function of openness norms, especially in times of ethnic change.

The Extended Contact Hypothesis: A Meta-Analysis on 20 Years of Research.

According to the extended contact hypothesis, knowing that in-group members have cross-group friends improves attitudes toward this out-group. This meta-analysis covers the 20 years of research that currently exists on the extended contact hypothesis, and consists of 248 effect sizes from 115 studies. The aggregate relationship between extended contact and intergroup attitudes was r = .25, 95% confidence interval (CI) = [.22, .27], which reduced to r = .17, 95% CI = [.14, .19] after removing direct friendship's contribution; these results suggest that extended contact's hypothesized relationship to intergroup attitudes is small-to-medium and exists independently of direct friendship. This relationship was larger when extended contact was perceived versus actual, highlighting the importance of perception in extended contact. Current results on extended contact mostly resembled their direct friendship counterparts, suggesting similarity between these contact types. These unique insights about extended contact and its relationship with direct friendship should enrich and spur growth within this literature.

Indirect contact predicts direct contact: Longitudinal evidence and the mediating role of intergroup anxiety.

Although the effects of direct and indirect forms of contact on intergroup relations are well documented, little is known about their longitudinal co-development. Based on the social-psychological literature, we hypothesize that indirect contact predicts future direct contact by reducing intergroup anxiety. Across five longitudinal studies (Study 1: German adults, N = 560; Study 2: German, Dutch, and Swedish school students, N = 6,600; Study 3: Northern Irish children, N = 1,593; Study 4: Northern Irish adults, N = 404; Study 5: German adults, N = 735), we systematically examined this effect, and further tested the mediating role of intergroup anxiety in Studies 3 to 5. Cross-lagged models provided consistent evidence for the positive effect of indirect contact on future direct contact, whereas a reduction in intergroup anxiety mediates this effect in most models. Results highlight the importance of indirect contact, which has the potential to increase direct contact, and thus promote social cohesion in diverse contexts, over time.
