When Do People Trust Their Social Groups?

Trust facilitates cooperation and supports positive outcomes in social groups, including member satisfaction, information sharing, and task performance. Extensive prior research has examined individuals' general propensity to trust, as well as the factors that contribute to their trust in specific groups. Here, we build on past work to present a comprehensive framework for predicting trust in groups. By surveying 6,383 Facebook Groups users about their trust attitudes and examining aggregated behavioral and demographic data for these individuals, we show that (1) an individual's propensity to trust is associated with how they trust their groups, (2) smaller, closed, older, more exclusive, or more homogeneous groups are trusted more, and (3) a group's overall friendship-network structure and an individual's position within that structure can also predict trust. Last, we demonstrate how group trust predicts outcomes at both individual and group level such as the formation of new friendship ties.Comment: CHI 201

Crowd behaviour and collective action

Crowd behaviour and collective action are integral to historical and political developments; they are the hands that turn the wheels of conflict and peace and propel societal change. Crowds engaging in collective action are the very embodiment of mass political mobilisation, as seen in countless examples from the Arab Spring to the Occupy movements to European anti-austerity rallies. In this chapter, we examine the contribution of social identity theory to understanding crowd behaviour and collective action, and discuss possibilities for continued theoretical integration and promoting social change. We first discuss competing theories of crowd behaviour, showing how those based on the social identity approach have progressed our understanding. We also discuss how the application of such an approach to understanding specific riot events has led to a conceptual and theoretical synthesis of collective action and crowd behaviour. We then examine social identity explanations of collective action more broadly, before analysing the apparent disconnect between established models of crowd behaviour and those of collective action, with a view to theoretical integration. Finally, we address the role of social identity in peace and conflict more broadly, and discuss future directions in this area of research

In small we trust: lay theories about small and large groups

Day-to-day interactions often involve individuals interacting with groups, but little is known about the criteria that people use to decide which groups to approach or trust and which to avoid or distrust. Seven studies provide evidence for a “small = trustworthy” heuristic, such that people perceive numerically smaller groups as more benevolent in their character and intentions. As a result of this, individuals in trust-sensitive contexts are more likely to approach and engage with groups that are relatively small than those that are relatively large. We provide evidence for this notion across a range of contexts, including analyses of social categories (Studies 1 and 2), ad hoc collections of individuals (Study 3), interacting panels (Studies 4-6), and generalized, abstract judgments (Study 7). Findings suggest the existence of a general lay theory of group size that may influence how individuals interact with groups

Social justice and psychology: what is, and what should be

This article proposes that all psychologists-and all psychologies-are innately concerned with justice, and yet there is no consensually defined discipline of psychology, and no consensual understanding of social justice. Adopting an intergroup and identitybased model of what is and what should be, we will describe the mechanisms whereby identities and perceptions of justice are formed, contested, and changed over time. We will argue that psychological research and practice have implications for social justice even where-and perhaps especially when-these are not made explicit. Psychology is considered as the product of diverse groups with distinct and evolving identities, and with differential access to resources and power, which dynamically contest different normative perceptions of justice

The impact of unpunished hate crimes: when derogating the victim extends into derogating the group

Just world research has shown that observers derogate victims more for their misfortunes if the perpetrator is not harshly punished (Lerner in J Personal Soc Psychol 1(4):355–360, 1980). However, few studies have investigated minority group derogation as a just world preservation strategy after instances of intergroup harm-doing. This study is among the first to demonstrate the derogation of both individual victims and of the victim’s minority group experimentally, using the context of a racist hate crime in Australia. In the present experiment, participants (N = 110) read a news article describing a hate crime against an Aboriginal Australian teenager and were informed that the perpetrator was harshly or leniently punished (secure vs. justice threat condition). Our results show that in the justice threat condition, participants not only derogated the individual Aboriginal Australian victim more after his death, they also expressed greater racism toward the victim’s group. An indirect effect of the justice threat condition on modern racism via individual victim derogation was observed, along with moderating effects of individual differences in belief in a just world. These findings provide support for the alarming hypothesis that racist hate crimes are not only the manifestation of a racist society, but may also bolster racial prejudices if leniently treated. The results highlight the important role of political and judicial authorities, whose response or non-response to a hate crime can exacerbate or ameliorate existing prejudices

The Whitewashing Effect: Using racial contact to signal trustworthiness and competence

The present research examines whether people use racial contact to signal positive and negative social attributes. In two experiments, participants were instructed to fake good (trustworthy/competent) or fake bad (untrustworthy/incompetent) when reporting their amount of contact with a range of different racial groups. In Experiment 1 (N = 364), participants faking good reported significantly more contact with White Americans than with non-White Americans, whereas participants faking bad did not. In Experiment 2 (N = 1,056), this pattern was replicated and was found to be particularly pronounced among those with stronger pro-White bias. These findings suggest that individuals may use racial contact as a social signal, effectively whitewashing their apparent contact and friendships when trying to present positively

Predicting Facebook users online privacy protection: risk, trust, norm focus theory, and the theory of planned behavior

The present research adopts an extended theory of the planned behavior model that included descriptive norms, risk, and trust to investigate online privacy protection in Facebook users. Facebook users (N = 119) completed a questionnaire assessing their attitude, subjective injunctive norm, subjective descriptive norm, perceived behavioral control, implicit perceived risk, trust of other Facebook users, and intentions toward protecting their privacy online. Behavior was measured indirectly 2 weeks after the study. The data show partial support for the theory of planned behavior and strong support for the independence of subjective injunctive and descriptive norms. Risk also uniquely predicted intentions over and above the theory of planned behavior, but there were no unique effects of trust on intentions, nor of risk or trust on behavior. Implications are discussed. © Copyrigh
