In this paper, we examine how social identity, moral obligation and the relationship between the two shaped support for the 2016 Academics for Peace petition in Turkey. We examine the pre-trial statements of nine defendants charged for signing the petition and appearing in court on the same day in December 2018. We first conduct an inductive thematic analysis on one statement, and then, using the themes from this analysis, we conducted a deductive thematic analysis on the remaining eight statements. In line with the existing studies, we find considerable evidence that social identity and moral obligation are invoked as key reasons for signing in this highly repressive context. However, rather than these being separate factors, the two are reciprocally constitutive. That is, social identities define moral obligations and, at the same time, enacting moral obligations defines identity (both the position of the individual in the group and the nature of the group in the world). In discussion, we consider the broader implications of a moralized view of social identities for our understanding of both collective action and social identity processes more generally., (© 2024 The Author(s).

In this paper, we conceptualize the days of mourning that followed the passing of Queen Elizabeth II. as constituting a liminal occasion, a moment of in-betweenness through which we can explore sense-making in times of transition. How do people navigate through liminal occasions, and are they always transformative? Through a rapid response ethnography (N interviews  = 64, N participants  = 122), we were able to capture the raw moments within which a collective comes together, as part of a national ritual, to transition from 'here' to 'there'. In our data, liminality prompted participants to strategically define British national identity and its future by positioning the Queen as representative of Britishness, her loss as a national identity loss. No longer taken for granted, participants reasserted the value of the monarchy as an apolitical and unifying feature in an otherwise divided society, characterizing the continuity of the institution as an essential part of British identity and society. The analysis illustrates how liminality offers a useful conceptual tool for addressing how temporality and change are negotiated in relation to a shared identity, and how navigating transitional moments brings with it political implications for the future., (© 2024 The Author(s).

This paper presents an analysis of identity leadership (Haslam et al., The new psychology of leadership: Identity, influence and power, Routledge, 2020) in the 1988 'Candlelight Demonstration' in Bratislava which was a precursor to the 1989 Velvet Revolution. The analysis is based on interviews with the five remaining leaders of the demonstration and addresses three core issues. First, how leaders use performative means (identity impresarioship) as well as limited rhetorical means (identity entrepreneurship) to assemble protestors and create a sense of shared identity amongst them. Second, how these strategies of mobilization are linked to the highly repressive context in which the demonstration took place. Third, we analyse the extent to which these strategies are rooted in a psychological understanding of the processes of mobilization. We conclude by addressing the implications for our general understanding of leadership and the mobilization of collective action and the need for more research into these processes under conditions of repression., (© 2023 The Authors.

On January 6th, 2021, Donald Trump's speech during a 'Save America' rally was followed by mass violence, with Trump's supporters storming the U.S. Capitol to prevent the certification of Joe Biden's victory in the presidential election. In its wake, there was a great deal of debate around whether the speech contained direct instructions for the subsequent violence. In this paper, we use a social identity perspective on leadership (and more specifically, on toxic leadership) to analyse the speech and see how its overall argument relates to violence. We show that Trump's argument rests on the populist distinction between the American people and elites. He moralises these groups as good and evil respectively and proposes that the very existence of America is under threat if the election result stands. On this basis he proposes that all true Americans are obligated to act in order prevent Biden's certification and to ensure that the good prevails over evil. While Trump does not explicitly say what such action entails, he also removes normative and moral impediments to extreme action. In this way, taken as a whole, Trump's speech enables rather than demands violence and ultimately it provides a warrant for the violence that ensued., (© 2023 The Authors.

The comprehensive analysis of social identity cannot simply focus on individuals' cognitive self-definition. Rather it should also theorize the social conditions that affect individuals' opportunities to act in terms of those self-definitions. We argue that the social distancing interventions associated with Covid-19 provide an opportunity to explore the significance of otherwise taken-for-granted social factors which routinely support and sustain individuals' identity enactments. Using qualitative data gathered with 20 members of the Scottish Muslim community (19 diary entries and 20 post-diary interviews), we explore their experiences of restricted access to community-relevant social spaces (e.g., mosques and prayer rooms). Our analysis shows that while these regulations could result in new opportunities for Muslims' religious identity enactments, they also impeded their abilities to act in terms of their religious identification. Addressing such impediments, we develop our understanding of the contextual factors that shape individuals' abilities to enact identity-defining norms and values., (© 2023 The Authors.

Much research addresses the proposition that identifying with a group shapes individuals' behaviour. Typically, such research employs experimental or survey methods, measuring or manipulating social identification and relating this to various outcome variables. Although shedding much light on the processes involved in the identity-behaviour relationship, such research tends to overlook the various constraints that limit individuals' abilities to act in accordance with their identities. Using interview data gathered in north India, we explore the factors affecting the enactment of a religious identity. More specifically, using data gathered at a religious mass gathering, we compare and contrast participants' reports of identity enactment when they are at the event and when they are in their home villages. These two contexts differ in terms of their social organization, especially the degree to which they are marked by the presence of a shared identity. Exploring participants' accounts of such differences in social organization, we consider the social processes that constrain or facilitate identity enactment. In so doing, our analysis contributes to a richer analysis of the identity-behaviour relationship., (© 2020 The Authors.

In crowds, to the degree one identifies with other crowd members one likely experiences a sense of common purpose, social connection and mutual support. Such is the psychological significance of these correlates of a shared identity that even others' close physical proximity can be pleasurable. However, such pleasure in others' proximity cannot be assumed: physical crowding can bring practical challenges and so potentially disturb the positive experience of crowd membership. In the research reported here, we explore crowd members' reports of such challenges and the ways in which these were interpreted and managed through reference to the beliefs and values associated with crowd members' shared identity. Our data arise from semi‐structured interviews (N = 33) with British Muslims after participating in the Hajj pilgrimage in Saudi Arabia. Exploring these data sheds light on the ways in which identity‐related beliefs and values can contribute to the maintenance of order and harmony even in situations where crowding could undermine the positive experience of others' proximity. Accordingly, our analysis advances our understanding of the self‐organization and self‐policing of crowds. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has triggered health-related anxiety in ways that undermine peoples' mental and physical health. Contextual factors such as living in a high-risk area might further increase the risk of health deterioration. Based on the Social Identity Approach, we argue that social identities can not only be local that are characterized by social interactions, but also be global that are characterized by a symbolic sense of togetherness and that both of these can be a basis for health. In line with these ideas, we tested how identification with one's family and with humankind relates to stress and physical symptoms while experiencing health-related anxiety and being exposed to contextual risk factors. We tested our assumptions in a representative sample (N = 974) two-wave survey study with a 4-week time lag. The results show that anxiety at Time 1 was positively related to stress and physical symptoms at Time 2. Feeling exposed to risk factors related to lower physical health, but was unrelated to stress. Family identification and identification with humankind were both negatively associated with subsequent stress and family identification was negatively associated with subsequent physical symptoms. These findings suggest that for social identities to be beneficial for mental health, they can be embodied as well as symbolic., (© 2021 The Authors.

Objectives: The Scientific Pandemic Insights group on Behaviours (SPI-B) as part of England's Scientific Advisory Group on Emergencies (SAGE), were commissioned by the UK Cabinet Office to identify strategies to embed infection control behaviours to minimize Covid-19 transmission in the long term., Methods: With minimal direct evidence available, three sources of information were used to develop a set of proposals: (1) a scoping review of literature on sustaining behaviour change, (2) a review of key principles used in risk and safety management, and (3) prior reports and reviews on behaviour change from SPI-B. The information was collated and refined through discussion with SPI-B and SAGE colleagues to finalize the proposals., Results: Embedding infection control behaviours in the long-term will require changes to the financial, social, and physical infrastructure so that people in all sections of society have the capability, opportunity, and motivation needed to underpin those behaviours. This will involve building Covid-safe educational programmes, regulating to ensure minimum standards of safety in public spaces and workspaces, using communications and social marketing to develop a Covid-safe culture and identity, and providing resources so that all sections of society can build Covid-safe behaviours into their daily lives., Conclusions: Embedding 'Covid-safe' behaviours into people's everyday routines will require a co-ordinated programme to shape the financial, physical, and social infrastructure in the United Kingdom. Education, regulation, communications, and social marketing, and provision of resources will be required to ensure that all sections of society have the capability, opportunity, and motivation to enact the behaviours long term., (© 2021 The Authors.

In this paper, we analyse the conditions under which the COVID-19 pandemic will lead either to social order (adherence to measures put in place by authorities to control the pandemic) or to social disorder (resistance to such measures and the emergence of open conflict). Using examples from different countries (principally the United Kingdom, the United States, and France), we first isolate three factors which determine whether people accept or reject control measures. These are the historical context of state-public relations, the nature of leadership during the pandemic and procedural justice in the development and operation of these measures. Second, we analyse the way the crisis is policed and how forms of policing determine whether dissent will escalate into open conflict. We conclude by considering the prospects for order/disorder as the pandemic unfolds., (© 2020 The Authors.

Notions of psychological frailty have been at the forefront of debates around the public response to the COVID-19 pandemic. In particular, there is the argument that collective selfishness, thoughtless behaviour, and over-reaction would make the effects of COVID-19 much worse. The same kinds of claims have been made in relation to other kinds of emergencies, such as fires, earthquakes, and sinking ships. We argue that in these cases as well as in the case of the COVID-19 pandemic, other factors are better explanations for fatalities - namely under-reaction to threat, systemic or structural factors, and mismanagement. Psychologizing disasters serves to distract from the real causes and thus from who might be held responsible. Far from being the problem, collective behaviour in emergencies - including the solidarity and cooperation so commonly witnessed among survivors - is the solution, one that should be harnessed more effectively in policy and practice., (© 2020 The British Psychological Society.)

Being alone is a basic and prevalent human experience, yet little is known about its effects on social identity. When alone, social identity may weaken because individuals feel their groups are less valuable or less salient. Conversely, it may strengthen because craving for bonding increases in-group perceived value. We tested these ideas with five experiments (N = 1312). Study 1, using existing groups, and Study 2, using minimal groups, showed that aloneness (vs. being with others) reduced in-group identity through its effect on in-group esteem. In Study 3, this effect was equivalent to the effect observed following social exclusion. Study 4 showed that individuals alone were indifferent in allocating money between in-group and out-group members. Last, Study 5 indicated that these effects do not stem from reduced salience of in-group members when alone. In conclusion, an alone mindset affects social identity by decreasing in-group esteem, signalling broad social implications for this basic social condition., (© 2025 The Author(s).

A common guideline for self-disclosure is that therapists should only share recovered personal experiences with clients (i.e., no longer distressing). However, theoretical rationale and empirical support for this claim is limited. Drawing on identity leadership theorizing, we investigated whether recovery disclosures are beneficial to the extent that they signal a therapist's aspirational prototypicality (i.e., embodiment of an aspirational identity for clients). Across two experimental studies (N = 545), we recruited clients, therapists and general population adults. Participants read a group therapy for depression vignette in which the therapist disclosed: nothing, professional experience with depression, current depression, recovered depression or recovered anxiety. Participants rated the prototypicality of the therapist, the extent to which they perceived the therapist positively, the therapist's expertness and the expected prognosis for therapy. Contrary to our hypotheses, the type of disclosure did not significantly affect positive perceptions, expertness or expected prognosis ratings. However, the therapist disclosing a recovered and relevant condition (recovered depression) was rated as significantly more aspirationally prototypical than the other therapists. Given prior evidence that group therapists are more effective when viewed as aspirationally prototypical, our findings suggest that recovery disclosures may represent one way therapists can signal their prototypicality and enhance their effectiveness., (© 2025 The Author(s).

In Eastern Europe, collective victim beliefs have become integral elements of national ideologies, especially amid rising geopolitical polarization. In this study, we investigated how exclusive victimhood was related to geopolitical attitudes in Hungary and Serbia. The study involved Serbian (N = 630) and Hungarian (N = 471) adult national samples stratified by gender, age, political orientation, and place of residence. As expected, exclusive victimhood predicted higher support for a geopolitical shift from the West (i.e., EU and US) to the East (i.e., Russia and China) via Euroscepticism in both samples. In Serbia, the strongest indirect effect was observed among participants with neutral attitudes towards the war in Ukraine. In Hungary, there was no expected moderated mediation while the direct effect of exclusive victimhood on the West-to-East geopolitical shift was largest for pro-Russian participants and non-significant for pro-Ukrainian participants. Different measures of ethnic identity showed no expected moderation effect, but an exploratory analysis revealed that exclusive victimhood partially mediated the relationship between identity measures (superiority and attachment) and support for a pro-Eastern (vs. pro-Western) geopolitical orientation. We discuss how the construals of the past based on exclusive victimhood shape future geopolitical preferences of the public in Hungary and Serbia., (© 2024 British Psychological Society.)

In two cross-sectional and two experimental studies across both advantaged and disadvantaged group members (N total  = 1980 from two national contexts, UK and Italy), we explored if perceptions of group relative prototypicality may explain the association of positive and negative contact with collective action. Specifically, across studies, we investigated subgroup relative prototypicality with respect to four different common identities (national, supranational, based on humanity, humanity values). In Studies 1-2, among advantaged group members, positive contact was positively associated with collective action intentions via greater relative prototypicality of disadvantaged groups; in Study 2, we also found that negative contact was negatively associated with collective action intentions via decreased relative prototypicality of disadvantaged groups. By contrast, among disadvantaged group members, relative prototypicality did not exert any mediation effects. Experimental Studies 3-4 using advantaged group member participants generally provided causal evidence that positive (imagined) contact increases relative prototypicality of the disadvantaged group (Study 3), and that relative prototypicality increases collective action (Study 4)., (© 2025 British Psychological Society.)

Cruelty and its link to injustice in contexts of humiliation have not received to date due attention from experimental psychosocial research. Aiming at filling this gap, this paper presents three studies with increasing degrees of experimental control (N total  = 1098) that show a dual opponent-process response to being targeted by potentially humiliating actions: while targets appraising more injustice internalize less the devaluation underlying the humiliation experience (thus partially dissolving the so-called "paradox of humiliation", Fernández et al., 2015, Personality and Social Psychology Bulletin, 41, 976), targets appraising more cruelty internalize more a devalued self-view and feel more humiliated. The fine balance between these two closely connected but distinct appraisals is key to understand the internal/subjective experience of targets: seeing themselves mainly as victims of injustice or cruelty will prevent or favour, respectively, their internalization of the devaluation and their feeling humiliated. This opposite pattern also impacts victims' reaction: Both appraisals relate to aggressive responses via anger but while appraising cruelty also paradoxically leads to powerless inertia, appraising injustice (including importantly the injustice of cruelty itself) leads to less powerlessness and more assertive agency. The theoretical and applied implications of approaching the victims of humiliation as victims of both an injustice and a cruelty are discussed., (© 2024 The Author(s).

Objectives: Characterization of psychotherapy as the "talking cure" de-emphasizes the importance of an active listener on the curative effect of talking. We test whether the working alliance and its benefits emerge from expression of voice, per se, or whether active listening is needed. We examine the role of listening in a social identity model of working alliance., Methods: University student participants in a laboratory experiment spoke about stress management to another person (a confederate student) who either did or did not engage in active listening. Participants reported their perceptions of alliance, key social-psychological variables, and well-being., Results: Active listening led to significantly higher ratings of alliance, procedural justice, social identification, and identity leadership, compared to no active listening. Active listening also led to greater positive affect and satisfaction. Ultimately, an explanatory path model was supported in which active listening predicted working alliance through social identification, identity leadership, and procedural justice., Conclusions: Listening quality enhances alliance and well-being in a manner consistent with a social identity model of working alliance, and is a strategy for facilitating alliance in therapy., (© 2024 The Author(s).

Introduction: Interventions to support behaviour change in people living with chronic health conditions increasingly use patient groups as the mode of delivery, but these are often designed without consideration of the group processes that can shape intervention outcomes. This article outlines a new approach to designing group-based behaviour change interventions that prioritizes recipients' shared social identity as group members in facilitating the adoption of established behaviour change techniques (BCTs). The approach is illustrated through an example drawn from research focused on people living with severe obesity., Methods: A prioritization process was undertaken in collaboration with stakeholders, including behaviour change experts, clinicians, and a former patient to develop an evidence-based, group intervention informed by the social identity approach to health. Three phases of development are reported: (1) identification of the health problem; (2) delineation of intervention mechanisms and operationalization of BCTs for group delivery and (3) intervention manualization. The fourth phase, intervention testing and optimization, is reported elsewhere., Results: A group-based behaviour change intervention was developed, consisting of 12 group sessions and 3 one-to-one consultations. The intervention aimed to support the development of shared social identity among recipients, alongside the delivery of evidence-based BCTs, to improve the likelihood of successful intervention and health outcomes among people living with severe obesity., Conclusions: A manualized intervention, informed by the social identity approach to health, was systematically designed with input from stakeholders. The development approach employed can inform the design of behavioural interventions in other health contexts where group-based delivery is planned., (© 2024 The Author(s).

While social psychology has contributed much to our understanding of collective action, other forms of resistance are understudied. However, in contexts of long-standing oppression-such as ongoing colonialism-and past repression of liberation struggles, other resistance strategies are important considering the constraints on overt, collective action in such contexts. This paper reports findings from an interview study in Puerto Rico (N = 22) exploring anti-colonial resistance. We analysed participants' own resistance, future preferred strategies, and descriptive norms of other ingroup members' resistance. Through thematic analysis, we identified six distinct forms of anti-colonial resistance. Notably, none of the participants reported participating in collective action. Instead, participants engaged in different forms of symbolic everyday resistance to preserve a positive, distinct cultural identity, and raise critical consciousness of the group's oppression. Additionally, more tangible resistance strategies included staying on the land and building independent economies. Overall, this study illustrates the importance of considering a more comprehensive set of resistance strategies in contexts of long-standing colonial oppression to recognize oppressed groups' agency and provide a better understanding of how people undermine destructive power., (© 2024 The Author(s).

Based on the Elaborated Social Identity Model of Crowd Behaviour, we tested in two experiments whether a forceful display of police power increases perceptions of illegitimacy of the police and the formation of resistance among protestors. In the high power condition, the police were dressed in riot gear (with helmets, armed with shields and batons). In the low power condition, the police were dressed in regular uniforms. In both studies, people participated in a demonstration against right-wing populism using a virtual reality setting and were either stopped by the police in riot gear or by the police in regular uniforms. The results of Study 1 (N = 155) show that the police in riot gear were evaluated as more illegitimate compared to the police in normal clothing. The results of Study 2 (N = 97) replicated this finding and illustrated that police in riot gear (compared to regular uniforms) increased protestors' intentions to engage in direct resistance against the police. This effect was mediated by perceptions of illegitimacy and anger directed at the police. Furthermore, weakly identified protestors were particularly affected by the display of power and were more likely to engage in anti-police resistance and collective action. Implications are discussed., (© 2024 The Author(s). British Journal of Social Psychology published by John Wiley & Sons Ltd on behalf of British Psychological Society.)

In the present research, we introduce and validate a single-item measure of identity leadership-the visual identity leadership scale (VILS). The VILS uses Venn diagrams of sets of overlapping circles to denote different degrees of alignment between a leader's characteristics and behaviours and a group's values and goals. Key advantages of the VILS over other existing multi-item scales are that it provides a holistic assessment of identity leadership, is short, and can be adapted to address novel research questions that are impractical to address with existing scales (e.g. in diary studies, assessing multiple comparisons of many leaders or groups). Data from three studies (conducted in India, the United States and Germany) provide evidence of the VILS' construct reliability and validity. Results also showcase the instrument's capacity to be adapted to assess variations of identity leadership-for example, by assessing a leader's convergence with descriptive and ideal notions of collective self (i.e. with 'who we are' and 'who we want to be'). We discuss the value of including the VILS in the toolbox that researchers and practitioners can utilize to expand our understanding of identity processes in leadership and group behaviour., (© 2024 The Authors.

In-between groups encompass individuals who simultaneously belong to social categories that are often seen as mutually exclusive in addition to maintaining their distinct group identity. The current paper sheds light on how members of in-between groups manage their relations within intergroup conflicts. Three studies were conducted among the Druze minority in Israel, a group that is ethnically Arab and shares the Arab identity with the Arab-Palestinian minority in Israel and simultaneously identifies as Israeli. In Study 1 (N = 300), we found that identification as Druze was positively associated with the identification as Arab and Israeli. In Study 2, we examined Druze's endorsement of conflict narratives compared to Jewish-Israeli and Palestinian citizens (N = 271). While the latter participants endorsed their ingroup narrative more than the outgroup narrative, Druze participants endorsed both narratives equally. In Study 3, we tested Druze's solidarity with the Palestinian minority against the 2018 Nation-State Law. We found that overall, Druze participants (N = 568) endorsed more inclusive amendments that benefited the Druze and Palestinians than exclusive amendments that benefited the Druze only. In all studies, we tested the role of identification with the rival groups. We discuss these findings and suggest possible underlying mechanisms., (© 2024 The Authors.

Emerging evidence suggests that social identities are an important determinant of adaptation following traumatic life experiences. In this paper, we analyse accounts of people who experienced child sexual abuse. Using publicly available talk of people who waived their right to anonymity following successful conviction of perpetrators, we conducted a thematic analysis focusing on trauma-related changes in their social identities. Analysis of these accounts highlighted two themes. The first highlights the acquisition in these accounts of unwanted and damaging identity labels. The second presents child sexual abuse as a key destructive force in terms of important identity work during childhood. Discussion of this analysis centres on the pathological consequences of social identity change. Both the loss of valued identities and the acquisition of aberrant and isolating identities are experienced and constructed as devastating by those affected by child sexual abuse. This has important implications, not only for those impacted by child sexual abuse but for how abuse is discussed in society, and how it is approached by policy makers, educators and individuals working with survivors and their families., (© 2024 The Authors.

We study a transcript of discourse recorded on an open mic during the mass suicide/murder of 909 members of a religious community in Jonestown in 1978. The 'Jonestown massacre' is often cited in psychology textbooks as a warning example of how powerful situations and charismatic leaders can lead ordinary people to extreme and destructive behaviours. These accounts suggest that individuals lose control of reason and will such that their behaviour becomes subject to outside control. We develop an alternative explanation of the mass killing as identity-based collective action. Our analysis shows how a shared understanding of the community's situation and the options available to them were constructed and contested in discourse. We demonstrate how Jim Jones served as impresario, entrepreneur and champion of identity, recognizing his followers' agency, initiating collective meaning-making and mobilizing action. Jones engaged his followers in jointly constructing the situation as hopeless, developing a shared view of their situated social identity and collectively formulating the identity-congruent solution of collective suicide as a hopeful act of collective agency. Our analysis points to the importance of addressing the conditions that sustain narratives of collective hopelessness and helping groups successfully choose non-extremist pathways out of hopelessness., (© 2024 The Author(s).

Shared social identity and social norms are often un(der)recognized within mass gatherings health literature, yet they can increase infectious disease transmission by motivating people to engage in risk-taking behaviours. Across three experiments (N total  = 1551), we investigated how shared social identities, perceived norms of resource-sharing, and perceived riskiness of sharing interact to shape decisions that can lead to disease transmission. In Experiment 1 (N = 528), we examined how shared social identity and perceived descriptive norms affect the likelihood of crowd members sharing resources that may contribute to disease spread. We then replicated this in Experiment 2 (N = 511) using perceived injunctive norms. In Experiment 3 (N = 512), we explored how high shared social identity, perceived norms, and perceived health risks of resource-sharing impact the likelihood of sharing that may, in turn, increase infectious disease transmission at mass gatherings. We found that high shared social identity interacts with perceived descriptive and injunctive norms, and low health risk perceptions, to increase the likelihood of accepting resources and giving resources at mass gatherings. We discuss the theoretical and practical implications for researchers, practitioners, and policymakers to build effective strategies to mitigate infectious disease transmission at mass gatherings., (© 2024 The Author(s).

The effectiveness of mutual help groups (MHGs) in promoting addiction recovery has been widely acknowledged. However, the psychological mechanisms underlying the impact of MHGs remain somewhat uncertain. Drawing on a social identity perspective, this study investigated a sequential mediation model in which social support is posited as a driving factor that enhances abstinence maintenance through group identification, recovery identity, and self-efficacy. A sample of 820 smokers, participating in a 6-month collective smoking cessation programme which included access to an online help group, completed measures of social support, group identification, smoker/ex-smoker identity, and self-efficacy at the programme's outset. Smoking abstinence was assessed 6 and 9 months later. The findings supported the proposed model, indicating that social support was positively associated with MHG identification, which, in turn, was related to a stronger recovery identity. Subsequently, recovery identity was associated with increased self-efficacy, and indirectly, with smoking abstinence at both measurement times. Additional analyses testing alternative mediation models further supported the validity of the proposed model. These findings suggest that social identity factors play significant roles in accounting for the effectiveness of MHGs for addiction recovery., (© 2024 The Author(s).

Although there have been numerous studies on the relations between group identification and ethnic prejudice, it is less clear whether their associations reflect stable individual tendencies or rather situational or temporal fluctuations. This longitudinal multilevel study aimed to fill this gap by examining the between- and within-person associations of identification with the national and superordinate human groups and levels of prejudice against multiple ethnic minorities. A total of 883 Italian majority adolescents (M age  = 15.66, SD = 1.15 at T1, 49.7% females) completed questionnaires at four time points over the course of 1 year. Results showed that national identification was related to more prejudice at the between-person level but to decreases in prejudice at the within-person level. Additionally, human identification contributed to lower levels of and steeper decreases in prejudice at both the between- and within-person levels. Common and unique associations also emerged across different ethnic minority targets, but only for between-person effects. Overall, this study highlights the importance of distinguishing stable individual levels and momentary fluctuations of both ingroup identifications and ethnic prejudice in order to orient future interventions aimed at improving the quality of intergroup relationships., (© 2024 The Author(s).

This paper discusses the importance of a social identity approach to crisis leadership in the context of global crises such as the Covid-19 pandemic and emphasizes the interconnected relationships between leaders and followers. I highlight the role of leaders in fostering unity and shaping citizens' responses especially during crises. I discuss the nature of crises and the significant role of political leaders in guiding societal responses and suggest that crisis leadership extends beyond individual competencies and behaviours and involves a shift from individual to collective responses. With this, I introduce the social identity approach to leadership that views leadership as a social influence process and emphasizes the importance of creating a sense of 'we-ness' among followers. Following from that, crisis leadership involves leaders constructing defining features of collective identity and efficacy to address crises appropriately. However, the value of this approach depends on the careful definition of shared identity boundaries, consideration of diverse experiences within society, the evolving nature of crisis leadership over time and potential consequences of crisis leadership. The sustainability of identity leadership, the dynamics of intergroup and subgroup processes, and the complexities of various crises are identified as areas requiring further research., (© 2024 The Author(s).

Experimental and survey research shows that a common group membership can result in increased levels of social support. Here we complement such research with qualitative data concerning the forms and function of such support. Specifically, we explore the mutual support reported by pilgrims undertaking the Hajj. This requires participants enact a series of identity-related beliefs and values (including specific rituals) in conditions that are practically and psychologically challenging. Using data obtained through semi-structured interviews (N = 33), we investigate how participants' shared identity facilitated their behavioural enactment of these identity-defining beliefs and values. We focus on how their shared understanding of their beliefs and values as Hajj pilgrims allowed various forms of support (psychological, material, informational, and behavioural) which helped participants translate their identity-related ideals into behaviour. Our analysis implies that a shared identity provides a frame of reference with which group members can recognize each other's identity-related concerns and what they need in order to enact their identity. In turn, it implies that in situations where there are practical and psychological constraints on behaviour, action in terms of one's social identity can be conceptualized as a joint accomplishment in which the mutual support of group members is key., (© 2024 The Author(s).

Building on the seminal studies of Solomon Asch and Muzafer Sherif, recent research has advanced our understanding of the mechanisms underlying social influence by applying a diffusion model analysis. Here, we combined the social identity approach to social influence with a diffusion model analysis to unravel the mechanisms underlying social influence. In particular, we aimed to disentangle whether the difference between in-group and out-group influence on perceptual decision-making is driven by a judgmental bias (i.e., changes in decision criteria) or a perceptual bias (i.e., changes in the uptake of sensory information). Preregistered analyses indicated that in-groups exerted stronger social influence than out-groups because in-groups induced a stronger perceptual bias than out-groups. This finding is in line with the single process assumption of the social identity approach because it implicates that the single process driving social influence (i.e., self-categorisation) translates into a change in a single subprocess of decision-making (i.e., biased information uptake). In conclusion, our results highlight that our theoretical understanding of social influence can be expanded by integrating the social identity approach with a diffusion model analysis., (© 2024 The Authors.

Identity fusion is a visceral feeling of oneness with a group, known to strongly motivate extreme pro-group behaviour. However, the evidence on its causes is currently limited, primarily due to the prevalence of cross-sectional research. To address this gap, this study analysed the evolution of fusion in response to a massive collective ritual, Korrika-a race in support of the Basque language-, over three time periods: before (n = 748) and immediately following participation (n = 402), and 7 weeks thereafter (n = 273). Furthermore, we explored the potential mediating roles of two key factors: perceived emotional synchrony, a sense of emotional unity among participants that emerges during collective rituals, and kama muta (moved by love), an unexplored emotion in relation to fusion, which arises from feelings of shared essence. The proportion of fused participants increased significantly after participation and remained stable for at least 7 weeks. Perceived emotional synchrony and kama muta apparently explained the effect of participants' behavioural involvement in the ritual on subsequent fusion, but only among those who were not previously fused with Korrika participants. We conclude that emotional processes during collective rituals play a fundamental role in the construction of identity fusion., (© 2024 The Authors.

This paper critically examines the normative versus non-normative distinction commonly used in collective action research. To explore the similarities and differences between antecedents of normative versus non-normative actions, we conducted a systematic review on diverse predictors of non-normative, radical and violent collective actions. We examined 37 social and political psychology studies published after 2010 and identified five recurring themes: identity, efficacy, injustice, emotions and norms. Findings exhibited significant overlaps with those predictors associated with normative collective action. Thus, a reconceptualization is needed to undermine the rigid boundaries between these action types, highlighting the intricate interplay of factors that transcend the conventional binary. Aiming to avoid conceptual ambiguity and challenge the perspective that associating particular collective actions with unwarranted violence using social norms as fixed and a priori, we propose the term 'confrontational collective action' to separate out form of action from societal approval. Through this reconceptualization, we discussed the main limitations in the literature, focusing on how studies approach normativity and efficacy and addressing the issue of decontextualization in the literature. This paper calls for a contextually informed understanding of confrontational collective action that recognizes what is seen as 'normative' can change over time through intra- and intergroup interactions., (© 2024 The Authors.

This article presents comments made by criminal justice personnel on the field experiment "Police Intervention Riots: The Role of Accountability and Group Norms. A Field Experiment." by Marceline B. R. Kroon. It notes that practitioners involved in this very difficult area of riot policing, tend not to have much contact with the academic community in helping to evaluate their training. The significance of this study may lie, not so much in what was done, but that it was done at all. The other personnel, on the other hand, found much of this research somewhat confusing and is difficult to read.

The studies reported in this paper address the predictions of the social identity model of deindividuation phenomena, or SIDE (Reicher, Spears & Postmes, 1995), concerning the strategic effects of visibility to the in-group: increasing the visibility of in-group members to each other increases their ability to support each other against the out-group and hence increases the expression of those aspects of in-group identity which would attract sanctions from this out-group. In a first study, where anti-fox hunting participants were rendered accountable to pro-fox hunters, the results were the opposite of those expected: participants actually decreased their endorsement of anti-hunt disruption (which had been defined as normative for the in-group but unacceptable to the out-group) when made more visible to the in-group. These results were explained by arguing that participants perceived the intergroup relationship as participants versus experimenters rather than as anti-versus pro-fox hunters and that in-group visibility was being used to resist an experimentally imposed definition of themselves as favouring disruptive activity. This interpretation was supported in a second study where participants' accountability to the pro-fox hunters was removed, leaving them solely accountable to the experimenters, and similar results were obtained. In the final study, the relationship between student participants and staff experimenters was made the explicit topic of study. As expected students increased their endorsement of activities that are normative to students but unacceptable to staff when visible to fellow in-group members. Together these results provide further support for the SIDE model. [ABSTRACT FROM AUTHOR]

A central theme in both medical sociology and health psychology is how people make sense of their symptoms. Both literatures, despite their stress on different aspects of the health evaluation process, see illness in terms of matching present symptoms to an underlying understanding of illness. In this paper we argue that such accounts have difficulty in explaining the impact of contextual factors on how symptoms are evaluated. We therefore propose a model based on self-categorization theory (Turner, Hogg, Oakes, Reicher & Wetherell, 1987). It is proposed that symptoms are evaluated, not against pre-existing illness representations, but by reference to their impact on situationally salient identities. In support of this an experiment is described which involves students who are training to be physical education (PE) teachers. They are defined either in terms of a 'PE student' identity or in terms of a 'gender' identity and asked to evaluate a number of scenarios which describe different illnesses and injuries. Overall, the results provide clear evidence that the significance ascribed to scenarios depends on which identity is salient and hence indicate the viability of a self-categorization theory approach to symptom evaluation.

This paper builds upon Reicher's (1984 a) model of deindividuation by arguing that manipulations of identifiability do not only affect the salience of social identity but also have strategic consequences for the expression of in-group stereotypes. Increasing the visibility of group members to a powerful out-group should decrease the ability of those members to express any aspects of their identity which would meet resistance from the out-group. A preliminary study found that making supporters of the Campaign for Nuclear Disarmament individually identifiable to a powerful out-group only affects the incidence of stereotypic behaviours which would be punishable by that out-group. In the main study, science students taking a psychology course are either defined as 'scientists' or as 'students'. They are then asked to complete a questionnaire about the psychology course consisting of items where difference from a staff norm would either be unpunishable or punishable. On the punishable items, the 'science' stereotype is compatible with the staff position, while the 'student' stereotype is incompatible. As expected, increased visibility of subjects to academic staff decreases conformity to the in-group stereotype for those defined as students but does not affect the behaviour of those defined as scientists. What is more, this pattern of results only holds for the punishable items. However, contrary to expectations, on the unpunishable items, increased visibility increases conformity to the in-group stereotype for both groups. Taken together, the two experiments confirm that immersing individuals in a group where they are anonymous to outsiders not only predisposes them to act in terms of social identity but also blunts out-group power in such a way as to allow full expression of that identity.

The study described here uses the social identity framework suggested by Tajfel and Turner to argue that de-individuation works by altering the salience of personal vs. social identity. Seventy students from science and 38 students from social science faculties were shown a film presenting arguments for and against vivisection, at the end of which they were told that science students had a pro- and social science students an anti-vivisection norm. Subjects were then told that they were being examined either as members of their faculty group or as individual students. They were either de-individuated or individuated. They were required to fill in an attitude questionnaire and to complete three quasi-behavioural measures. It was predicted that the group condition should increase salience of social identity and adherence to the group norm. It was also predicted that de-individuation in the group condition would further increase salience and hence normative behaviour, while in the individual condition de-individuation would decrease salience and hence normative behaviour. The first prediction was upheld on all the measures, and the second was partially confirmed. [ABSTRACT FROM AUTHOR]

This paper aims to extend the social identity approach to crowd behaviour (Reicher, 1984, 1987) in order to understand how crowd events, and crowd conflict in particular, develop over time. The analysis derives from a detailed account of a violent confrontation between students and police during a demonstration held in November 1988- the so-called `Bank of Westminster'. It focuses on how students came to be involved in the conflict, how the conflict spread and upon the psychological consequences of involvement. This analysis is used to develop general hypotheses concerning the initiation and development of collective conflict, it is concluded that, while the social identity model is of use in understanding these phenomena, it is necessary to recognize how social categories are constructed and reconstructed in the dynamics its of intergroup interaction.

According to traditional models of deindividuation, lowered personal identifiability leads to a loss of identity and a loss of internalized control over behaviour. This account has been challenged by arguing that manipulations of identifiability affect the relative salience of personal or social identity and hence she choice of standards to control behaviour. The present study contributes to an extension of this argument according to which identifiability manipulations do not only affect the salience of social identity but also the strategic communication of social identity. Reicher and Levine (1993) have shown that subjects who are more identifiable to a powerful outgroup will moderate the expression of those aspects of ingroup identity which differ from the outgroup position and which would be punished by the outgroup. Here we seek to show that, in addition, subjects who are more identifiable to a powerful outgroup will accentuate the expression of those aspects of ingroup identity which differ from the outgroup position but which would not be punished by the outgroup. This is because, when identifiable, subjects may use such responses as a means of publicly presenting their adherence to group norms and hence as a means of establishing their right to group membership. A study is reported in which 102 physical education students are either identifiable (I) or not identifiable (NI) to their academic tutors. They are asked to respond on a number of dimensions where pilot interviews show the ingroup stereotype to differ from outgroup norms. Expressions of difference from the outgroup position would lead to punishment on some of these dimensions (P items) but would no, lead to punishment for others (NP items). The predicted interaction between identifiability and item type is highly significant. [ABSTRACT FROM AUTHOR]

In this response, I welcome Pratto's wide ranging and innovative contribution on the social psychology of power. It fulfils an important role in opening up debate around an issue of key importance for our discipline. At the same time (and to further that debate), I take issue with both of her core arguments: First, that power should not be seen as relational but rather about one's ability to reach one's desired ends and, second, that these ends are ultimately about survival. More fundamentally, though, I argue that Pratto's analysis is limited by the fact that she takes the subject of power for granted. This ignores a wealth of research which shows, on the one hand, how power constitutes the nature of subjects and, on the other, how subjects (especially collective subjects - groups) constitute power. It is through exploring these dynamics that we can understand power and its relevance to social life., (© 2015 The British Psychological Society.)

Positive experiences of groups (e.g., the extent to which groups are important and supportive) tend to be associated with better retirement adjustment outcomes. However, group experiences are not always positive, and we know little about their varied contribution to adjustment outcomes. We addressed this gap by exploring the nature of social group memberships - in terms of varying positive and negative experiences of groups - to better understand how social group memberships shape retirement adjustment, life satisfaction and mental health. A latent profile analysis (using data from 489 retirees and their membership of 1887 groups) identified four profiles of social group memberships: optimal (63%), slightly straining (13%), low-supportive (18%) and ambivalent (6%). Subsequent regression analysis showed that these different profiles of group membership were differentially associated with retirement adjustment outcomes: belonging to more optimal groups was associated with better perceived adjustment, higher life satisfaction and better mental health, while belonging to slightly straining and ambivalent groups contributed to poorer adjustment, lower life satisfaction and greater depression. These findings have implications for theory and practice, not least because they advance our understanding of the diversity of people's group memberships and their contribution to retirement and health outcomes., (© 2023 The Authors.

Across a range of recent terrorist attacks in the United Kingdom, the question of how crowds behave in confined public space is an important concern. Classical theoretical assumptions are that human behaviour in such contexts is relatively uniform, self-interested and pathological. We contest these assumptions by reporting on a study of public response to a marauding knife attack that occurred on London's underground rail network in 2015. The analysis draws primarily upon footage from 27 CCTV cameras positioned across the station footprint supplemented by social media, news footage, radio logs and incident reports. Using an innovative methodology, we topographically and chronologically mapped behaviours during the incident. The analysis demonstrates that while rapid egressions occurred as the threat escalated, at every phase of the incident members of the public intervened spontaneously with coordinated, purposeful, socially oriented actions. This behavioural pattern contrasts with classical assumptions of a chaotic and apathetic crowd in emergencies. We highlight eight complementary categories of actions in the public response that appeared functional for the collective safety of the crowd during the short period before the police arrived. The policy implications for emergency planning, and the methodological innovations involving the use of video data are discussed., (© 2023 The Authors.

We analysed tweets from five English-speaking Canadian political parties in the year leading up to the 2019 federal election to explore both prejudicial and inclusive rhetoric in relation to Muslim identities on social media. We used structural topic modelling to understand what topics were discussed before moving to a rhetorical approach to analyse how topics were discussed. We identified 10 topics. Seven talked about Muslim groups in primarily inclusive ways, including depicting the positive contributions to Canadian society, creating ideological space for Muslim religious practices and invoking superordinate identities with victims of hate crimes to cultivate solidarity. However, the effectiveness of inclusive rhetoric was sometimes questioned due to omitting the subgroup-specific prejudice faced by Muslims. Prejudicial rhetoric occurred in three of the topics due to the nativist populist PPC party depicting Muslims as a threat to Canadian values, as hostile to people from other religious faiths, and depicting 'elites' in society as concealing the 'true' information concerning Muslims. The study contributes to understanding how politicians attempt to cultivate minority inclusion/exclusion in multicultural contexts through social media, as well as understanding the rhetoric of nativist populism in Canada and its similarities to other Global North contexts., (© 2023 The Authors.

This paper fits into the SIDE perspective (Reicher, Spears, & Postmes, 1995; Postmes, Spears, Lea, & Reicher, 2000), which emphasises the importance of integrating the cognitive and strategic dimensions of group processes. Our study examines the decisions made by senior police officers during a simulation exercise of a crowd event. The analysis shows, firstly, that officers are deeply concerned about their accountability to a variety of audiences, both internal and external to the police force. Second, these different audiences pressure them to act in different, and sometimes contradictory, ways. What counts, then, is the overall balance between accountability concerns. Third, this balance - and, with it, police perceptions and decisions - alters in the course of an event. More specifically, with escalating conflict, the balance of accountability concerns moves increasingly in the direction of undifferentiated intervention against crowd members. In discussion, we consider both the theoretical implications of this analysis for research on group processes (in particular the importance of accountability issues once one moves beyond the laboratory and deals with groups that have a past and future and in which membership is more than simply an act of choice) and the practical implications in terms of crowd policing.

This paper presents findings from the British Broadcasting Corporation (BBC) prison study - an experimental case study that examined the consequences of randomly dividing men into groups of prisoners and guards within a specially constructed institution over a period of 8 days. Unlike the prisoners, the guards failed to identify with their role. This made the guards reluctant to impose their authority and they were eventually overcome by the prisoners. Participants then established an egalitarian social system. When this proved unsustainable, moves to impose a tyrannical regime met with weakening resistance. Empirical and theoretical analysis addresses the conditions under which people identify with the groups to which they are assigned and the social, organizational, and clinical consequences of either doing so or failing to do so. On the basis of these findings, a new framework for understanding tyranny is outlined. This suggests that it is powerlessness and the failure of groups that makes tyranny psychologically acceptable. [ABSTRACT FROM AUTHOR]

In our rejoinder, we concentrate on responding to Zimbardo's criticisms. These criticisms involve three broad strategies. The first is to turn broad discussion about the psychology of tyranny into narrow questions about the replication of prison conditions. The second is to confuse our scientific analysis with the television programmes of 'The Experiment'. The third is to make unsupported and unwarranted attacks on our integrity. All three lines of attack are flawed and distract from the important theoretical challenge of understanding when people act to reproduce social inequalities and when they act to challenge them. This is the challenge that Turner identifies and engages with in his commentary. [ABSTRACT FROM AUTHOR]

This paper presents a discursive analysis of 172 suicide notes left by 120 suicide victims. Instead of searching for the underlying psychological reasons for suicide in the content of notes, we argue that such notes should be viewed as acts of communication which serve to manage the blame accorded to both author and recipients of the suicide note. Consequently notes may provide evidence of socially shared beliefs as to when suicide is more or less acceptable. The analysis largely confirms this approach. It is found that matters relating to blame are referred to more frequently than any other issue (87% of notes). The precise arguments which are used to justify the actions of both self and others are then described in detail and some evidence is provided that the nature of these arguments may vary as a function of the social position of the author and also the identity of the recipient. The implications of these findings, and for a general use of a discursive approach to suicide, are then discussed. Copyright © 2000 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
