Polarization is the psychological foundation of collective engagement

The term polarization is used to describe both the division of a society into opposing groups (political polarization), and a social psychological phenomenon (group polarization) whereby people adopt more extreme positions after discussion. We explain how group polarization underpins the political polarization phenomenon: Social interaction, for example through social media, enables groups to form in such a way that their beliefs about what should be done to change the world-and how this differs from the stance of other groups-become integrated as aspects of a new, shared social identity. This provides a basis for mobilization to collective action.

Becoming "us" in digital spaces: How online users creatively and strategically exploit social media affordances to build up social identity

Social media has become a major platform for information-exchange, discourse, and protest and has been linked to a wide range of pressing macro developments. Consequenlty, there is significant interest from scholars as well as from the wider publuc to understand how social media affordances interact with human behavior. In attempts to address these demands, the present article borrows from the social identity tradition to explain group formation processes in Web 2.0 and other online ecosystems. We propose that online users creatively and strategically exploit the affordances provided by platforms and technologies to construct and perform collective selfhood. We emphasize the relevance of community development, norm consensualization, and emotional alignment as recursive dynamic processes that - in symbiosis - provide a functional basis for social identities. We outline these proposed mechanisms based on a corpus of interdisciplinary literature and suggest avenues for future research.

The Salience of Children Increases Adult Prosocial Values

Organizations often put children front and center in campaigns to elicit interest and support for prosocial causes. Such initiatives raise a key theoretical and applied question that has yet to be addressed directly: Does the salience of children increase prosocial motivation and behavior in adults? We present findings aggregated across eight experiments involving 2,054 adult participants: Prosocial values became more important after completing tasks that made children salient compared to tasks that made adults (or a mundane event) salient or compared to a no-task baseline. An additional field study showed that adults were more likely to donate money to a child-unrelated cause when children were more salient on a shopping street. The findings suggest broad, reliable interconnections between human mental representations of children and prosocial motives, as the child salience effect was not moderated by participants’ gender, age, attitudes, or contact with children.

A Personal Model of Trumpery: Linguistic Deception Detection in a Real-World High-Stakes Setting

Language use differs between truthful and deceptive statements, but not all differences are consistent across people and contexts, complicating the identification of deceit in individuals. By relying on fact-checked tweets, we showed in three studies (Study 1: 469 tweets; Study 2: 484 tweets; Study 3: 24 models) how well personalized linguistic deception detection performs by developing the first deception model tailored to an individual: the 45th U.S. president. First, we found substantial linguistic differences between factually correct and factually incorrect tweets. We developed a quantitative model and achieved 73% overall accuracy. Second, we tested out-of-sample prediction and achieved 74% overall accuracy. Third, we compared our personalized model with linguistic models previously reported in the literature. Our model outperformed existing models by 5 percentage points, demonstrating the added value of personalized linguistic analysis in real-world settings. Our results indicate that factually incorrect tweets by the U.S. president are not random mistakes of the sender.

Helping in the context of refugee immigration

We review psychological approaches of helping behavior in the context of refugee immigration. Refugee migration, compared with nonrefugee migration, is characterized by greater forcedness and related perils. Taking into account perceptions of forcedness and perils, we examine potential helpers' responses at each of four successive stages toward helping people in perilous, distressing, or emergency situations: (1) noticing and recognizing distressing, help-demanding conditions; (2) taking responsibility; (3) knowing how to help; and (4) transfer of one's knowledge into action. In so doing, we discuss the role of different motives and functions of providing help (e.g. preserving refugees' dependency or facilitating their autonomy) and implications of unequal power relations between help providers and refugees.

Beyond Allyship: Motivations for Advantaged Group Members to Engage in Action for Disadvantaged Groups

White Americans who participate in the Black Lives Matter movement, men who attended the Women's March, and people from the Global North who work to reduce poverty in the Global South-advantaged group members (sometimes referred to as allies) often engage in action for disadvantaged groups. Tensions can arise, however, over the inclusion of advantaged group members in these movements, which we argue can partly be explained by their motivations to participate. We propose that advantaged group members can be motivated to participate in these movements (a) to improve the status of the disadvantaged group, (b) on the condition that the status of their own group is maintained, (c) to meet their own personal needs, and (d) because this behavior aligns with their moral beliefs. We identify potential antecedents and behavioral outcomes associated with these motivations before describing the theoretical contribution our article makes to the psychological literature.

SARS-Cov-2 and environmental protection: A collective psychology agenda for environmental psychology research

While the virus SARS-CoV-2 spreads all over the world, most countries have taken severe measures to protect their citizens and slow down the further spread of the disease COVID-19. These measures affect individuals, communities, cities, countries, and the entire planet. In this paper, we propose that the tremendous consequences of the corona crisis invite environmental psychology to focus more strongly on research questions that address major societal challenges from a collective psychology perspective. In particular, we stress that the corona crisis may affect how people appraise - and potentially respond to - the looming climate crisis. By consistently pointing out systemic links and their human factor, environmental psychology can become central to a scientific agenda of a sustainable 'post-corona society'. In order to provide a framework for future research towards a sustainable societal transformation, we build on the Social Identity Model of Pro-Environmental Action (SIMPEA) and extend its scope to understand people's responses following the corona crisis. The model allows predictions of previously not explicitly included concepts of place attachment, nature connectedness, basic psychological needs, and systems thinking. It may serve as a guiding framework for a better understanding of the transformation towards a sustainable future.

From marches to movements: building and sustaining a social movement following collective action

Collective action has the potential to have large-scale implications for a society. We review the processes that are key to understanding the path from collective action to the continuation and success of a social movement. First, we consider how the experience of participating in collective action can foster continued commitment to a cause. Next, since gaining broader support from society is key to the success of social movements, we discuss how the very nature of collective action employed can mobilize support or elicit backlash from members of the general public. Finally, we describe the role of movement leaders whose task is to unite movement participants while also mobilizing the broader society to rally behind the cause for social change. Emergent research on the consequences of collective action contributes to our understanding of the dynamic processes involved in maintaining a movement.

The psychology of online activism and social movements: relations between online and offline collective action

We review online activism and its relations with offline collective action. Social media facilitate online activism, particularly by documenting and collating individual experiences, community building, norm formation, and development of shared realities. In theory, online activism could hinder offline protests, but empirical evidence for slacktivism is mixed. In some contexts, online and offline action could be unrelated because people act differently online versus offline, or because people restrict their actions to one domain. However, most empirical evidence suggests that online and offline activism are positively related and intertwined (no digital dualism), because social media posts can mobilise others for offline protest. Notwithstanding this positive relationship, the internet also enhances the visibility of activism and therefore facilitates repression in repressive contexts.

Political solidarity: A theory and a measure

Political solidarity is often key to addressing societal injustice. Yet social and political psychology are without a common definition or comprehensive measure of this construct, complicating advancements in this burgeoning field. To address these gaps, we advance a novel understanding and measure of this construct. We conceptualized political solidarity as a construct consisting of three factors—allyship with a minority outgroup, a connection to their cause, and a commitment to working with them to achieve social change—that can emerge within and across social groups. Five studies empirically supported our conceptualization and measure; all participants were Canadian university students. In Study 1, 1,594 participants completed the initial 30-item pool. A series of exploratory factor analyses, along with indices of factor retention, supported the three-factor model. We retained three items per factor to create the 9-item Political Solidarity Measure (PSM). This three-factor model adequately fit Study 2 data (N = 275). In Study 3 (N = 268), we found evidence of the PSM’s convergent and discriminant validity. Studies 3 and 4 assessed the PSM’s retest stability in the medium-term (three to six months; Study 3) and short-term (a three-week period; Study 4; N = 126). Finally, we demonstrate the PSM’s predictive validity in Study 5 (N = 221). Controlling for modern racism, political orientation, and gender, PSM scores predicted collective action intentions and behavior benefitting the outgroup: Participants who reported higher political solidarity donated more to the outgroup’s cause and were more likely to agree to create a message of support.

#Globalcitizen: An Explorative Twitter Analysis of Global Identity and Sustainability Communication

(1) Background: global citizenship is often associated with pro-social and pro-environmental attitudes, beliefs and behaviors. Much of this research relies on questionnaire studies, whereas studies drawing on naturally occurring daily communications are under-used. In this paper, we analyse the content that users publish on Twitter related to the issue of global identity and citizenship. (2) Methods: we assessed word frequencies and associated hashtags of 35,237 tweets marked with the hashtag #globalcitizen. A sentiment analysis was conducted to investigate the moods and emotions of the tweets. (3) Results: in line with expectations derived from social identity theory, we found that associated words and hashtags were more often linked to themes of common good/disadvantaged groups than they were to the topic of nature and environment. Providing evidence for an empowerment function of global citizenship, the sentiment analysis suggests that global citizenship is related to rather positive emotions. (4) Conclusion: these findings reveal how identity constructions in social media predict associated contents and possibly pathways to social change.

Collective Emotions and Social Resilience in the Digital Traces After a Terrorist Attack

After collective traumas such as natural disasters and terrorist attacks, members of concerned communities experience intense emotions and talk profusely about them. Although these exchanges resemble simple emotional venting, Durkheim’s theory of collective effervescence postulates that these collective emotions lead to higher levels of solidarity in the affected community. We present the first large-scale test of this theory through the analysis of digital traces of 62,114 Twitter users after the Paris terrorist attacks of November 2015. We found a collective negative emotional response followed by a marked long-term increase in the use of lexical indicators related to solidarity. Expressions of social processes, prosocial behavior, and positive affect were higher in the months after the attacks for the individuals who participated to a higher degree in the collective emotion. Our findings support the conclusion that collective emotions after a disaster are associated with higher solidarity, revealing the social resilience of a community.

Whose tweets? The rhetorical functions of social media use in developing the Black Lives Matter movement

Research on collective action frequently characterizes social media as a tool for mobilization. However, social media activity can fulfil a variety of different functions for social change. In particular, the rhetorical functions of social media use by social movements are not well understood. We address this shortfall by analysing the rhetorical functions of Twitter use during an early stage of the Black Lives Matter social movement. We examine how activists used Twitter to balance competing aims for social change, such as growing the movement beyond disadvantaged-group members, while preventing appropriation or dilution of their message by advantaged-group 'allies'. We find that although Twitter users promote different, and often competing, definitions of the issues that the movement represents, rhetorical strategies are used to advance inclusive definitions that focus on racism. When activists address alternative definitions of movement actors and issues, representations of Otherness are used to characterize the proponents of these definitions as in opposition to the movement. Finally, we find that one way of resolving the tension between growing the movement and promoting disadvantaged-group control is by using identity and technology resources to explicitly define (1) how different groups can be movement advocates, and (2) action strategies for social change.

Celebrity suicide on Twitter: Activity, content and network analysis related to the death of Swedish DJ Tim Bergling alias Avicii

BACKGROUND

Media recommendations for suicide reporting are recommended to prevent imitative suicide but little is known about social media reactions to different revelations about celebrity suicide.

METHODS

Using the Twitter Application Programming Interface (API), we recorded public tweets mentioning Avicii from the day when his death was reported (N = 2,865,292). We compared that data with a dataset of random tweets. Furthermore, we recorded tweets including suicide in 124 languages before Avicii's death (N = 5,939,107). We processed English tweets mentioning Avicii with the Linguistic Inquiry and Word Count (LIWC) to quantify the frequency of affects and related linguistic signals. We also processed the text of tweets to detect tweets mentioning the suicide method, and we retrieved the list of followers of users who tweeted about the method. We constructed reply networks from the dataset, analysing three networks corresponding to the major news events about Avicii's death.

RESULTS

Avicii's suicide sparked immediate strong interest with both positive (χ² = 781.06, p < 10^-6) and negative emotional expressions (χ² = 1518.5, p < 10^-6) in comparison to baseline levels. Subsequent revelations were associated with smaller peaks with mainly negative emotional content after Avicii's death was revealed as a suicide (χ² = 33.2, p < 10^-6 and after news about the suicide method (χ² = 274.93, p < 10^-6). Tweeting about the suicide method was infrequent, but twitter users who covered the method had more followers that users who did not (D = 0.1675, p < 10^-6; t = 19.87, p < 10^-6), and a noteworthy number of users had considerable exposure to the suicide method.

LIMITATIONS

This was a descriptive analysis.

CONCLUSIONS

Twitter users showed strong interest in news about Avicii's death and Avicii's suicide, but less so in the suicide method, and showed distinct tweeting behaviours based on the different revelations.
