The social identity theory of leadership: Theoretical origins,research findings,and conceptual developments

Over the past decade the social identity theory of leadership (Hogg, 2001a; Hogg & van Knippenberg, 2003) has reinvigorated social psychological research on leadership by reconnecting leadership to the social psychology of influence, and by explicitly elaborating on the (social) identity function, and associated social cognitive and social interactive processes, associated with leadership. The main tenet is that group prototypical leaders are better supported and more trusted, and are perceived as more effective by members than are less prototypical leaders; particularly when group membership is a central and salient aspect of members’ identity and members identify strongly with the group. This hypothesis has attracted unequivocal support across numerous studies, research teams, and research paradigms. In this article we describe the social identity theory of leadership and its conceptual origins, and overview the state of evidence. The main focus of the article is on new conceptual developments and associated empirical advances; including the moderating roles of uncertainty, group innovation and creativity, deviance, “norm talk”, charisma, fairness, as well as the extension of the social identity theory of leadership to an intergroup context. Throughout we identify directions for future empirical and conceptual advances.     

Uncertainty, entitativity, and group identification

Two studies examined the effects of self-uncertainty and ingroup entitativity on group identification. From uncertainty reduction theory (Hogg, 2000), it was hypothesized that people would identify most strongly with their group if they felt self-conceptually uncertain and the group was highly entitative. Study 1 was a field experiment (N = 114) in which the perceived entitativity of participants’ political party was measured, and self-uncertainty was primed (high vs. low). Study 2 was a laboratory experiment (N = 89) with ad hoc non-interactive groups. Uncertainty was primed as in Study 1, but perceived entitativity was manipulated. In both cases the dependent variable was a multi-item measure of group identification. The hypothesis was fully supported in both studies—participants identified more strongly when they were uncertain and the group was highly entitative. Implications of this research for the role of uncertainty and social identity in extremism, orthodoxy, and ideological belief systems are discussed.     

Interpersonal attraction,social identification and psychological group formation

Two perspectives on the nature of the social group and psychological group formation are discussed. The traditional social cohesion approach traces group formation to processes of interpersonal attraction, while the social identity approach defines the group in cognitive terms and considers identification, or self-categorization, to be the mechanism of psychological group formation. On the basis of an experiment by Turner, Sachdev and Hogg (1983) it is hypothesized that interpersonal attraction (positive or negative) is related to group formation only in so far as it enhances intergroup distinctiveness. This hypothesis is experimentally tested in a 2 × 3 (interpersonal liking/disliking per se versus no explicit categorization/random categorization/criterial categorization on the basis of affect) factorial design employing the ‘minimal group’ paradigm. People who like each other and were not explicitly categorized formed a group. This effect was enhanced by criterial categorization but disappeared when categorization was random. Although the results do not support the hypothesis, they are not explicable in social cohesion terms. A social identity explanation is furnished—attraction influences group formation by acting, under certain specifiable conditions, as a cognitive criterion for common category membership. This explanation is located in current theorizing and is proposed as part of a reconceptualization of the relationship between interpersonal attraction and group formation.     

Group Membership,Status, and Social Power Preference1

The power literature supports the notion that power‐base preferences can serve as a means for gaining advantage over others, thereby satisfying the personal self. Here, we inquired whether the use of power bases also serves as a means for gaining in‐group advantage, thereby satisfying the social self. A 2 × 3 × 2 design, including group membership (in‐group/out‐group), influencing agent's status (low, same, high), and gender as independent variables was employed. After reading scenarios describing work‐situation conflicts that differed by the relative status of the influencing agent and group membership of the target person, students and workers completed the Interpersonal Power Inventory for assessing power usage. In general, participants attributed greater use of harsh bases toward the out‐group. Status effects were obtained for in‐group targets and were less clear for out‐group targets. The discussion addresses theoretical implications for both the power interaction model and social identity theory, as well as practical ones for intergroup relations in organizations.     

Social Identity Theory and the Crisis of Confidence in Social Psychology: A Commentary, and Some Research on Uncertainty Reduction

The role played by social identity theory in responding to the crisis of confidence in social psychology is described. It is a theory that addresses group processes and intergroup relations by separating and articulating different levels of explanation. Social categorization depersonalizes perception, cognition, affect and conduct in terms of relevant ingroup or outgroup prototypes, and social categorization of self, in conjunction with beliefs about the nature of intergroup relations, is responsible for specific manifestations of group behavior. Social identity theory continues to develop. In this article we focus on the motivational role of subjective uncertainty reduction in social identification – a model is outlined (Hogg & Mullin, 1999), and data from a 2 × 2 minimal group experiment in which categorization and uncertainty were orthogonally manipulated ( N = 151) are presented. As predicted, categorization produced discrimination, elevated identification, and reduced uncertainty, but only, or more markedly, under conditions where subjective uncertainty was relatively high.     

Prototypical similarity,self-categorization,and depersonalized attraction: A perspective on group cohesiveness

In contrast to traditional approaches that widely equate group cohesiveness with interpersonal attraction, self-categorization theoryargues that self-categorization depersonalizes perception in terms of the group prototype, and transforms the basis of interindividual attitude (liking) from idiosyncracy into prototypicality. An implication is that while attraction in interpersonal relationships relates to overall similarity, attraction among group members is based on prototypical similarity. To test this idea, subjects (N = 219) participated in an experiment in which they reported their attitude towards an individual who would be their partner, or a fellow group member (of either group ‘Visual’ or group ‘Tactile’) for a subsequent task. Subject-target similarity varied on each of two dimensions: dimension ‘A’ was more prototypical of group ‘Visual’, and dimension ‘F’ of group ‘Tactile’. The independent variables of social orientation (interpersonal, group ‘Visual’, group ‘Tactile’), similarity on dimension A (A ±), and dimension F(F±) were manipulated in a 3 × 2 × 2 design. The three hypotheses tested in this experiment were generally supported. Subjects preferred prototypically similar group members to interpersonal partners, and downgraded prototypically dissisimilar group members (HI). Identification was positively related to target evaluation (H2), more strongly for prototypically similar than dissimilar targets (H3), and the identification-attraction relationship was mediated by perceived prototypical similarity. Group-based effects were independent of perceptions of overall similarity.     

Reaching Across the DMZ: Identity Uncertainty and Reunification on the Korean Peninsula

Drawing on uncertainty‐identity theory (Hogg, 2012), we explore the effects of uncertainty concerning a specific social identity on group identification and attitudes toward subgroup integration and separation in South Koreans' nested identity context (N = 148). All variables were measured. Path analysis revealed, as predicted, that superordinate identity uncertainty weakened superordinate identification and subgroup identity uncertainty weakened subgroup identification. We also found that subgroup identity uncertainty strengthened superordinate identification. This effect was stronger for those who perceived their superordinate group prototype and subgroup prototype to be distinct and nonoverlapping. Furthermore, superordinate identity uncertainty decreased reunification intentions by weakening superordinate identification. Subgroup identity uncertainty increased reunification intentions by strengthening superordinate identification only for those who perceived their superordinate group prototype and subgroup prototype to be distinct and nonoverlapping. Implications for uncertainty identity theory and intergroup relations are discussed.     

Individual versus collective responses to membership in a low-status group: the effects of stability and individual ability

To test predictions of social identity theory (SIT; M. A. Hogg & D. Abrams, 1988; H. Tajfel & J. C. Turner, 1979) and the 5-stage model (FSM; D. M. Taylor & D. J. McKirnan, 1984) concerning reactions to membership in a low-status group, the authors led 112 pupils to believe that another (anonymous) class outperformed their class. In an overall permeable and legitimate intergroup context, the authors manipulated the stability of the low group status and the individual ability of the group members. Contrary to SIT and FSM, the pupils generally favored collective normative action. Individual mobility was preferred only by group members, especially boys, with high individual ability who thought that the low status of their group was stable. The results support FSM assumptions (a) that individual ability is a powerful determinant of intergroup behavior but (b) that one should consider its impact in combination with perceived stability.     

Social Categorization and Stereotyping In vivo: The VUCA Challenge

A substantial literature has examined the nature of social categorization, a fundamental process having important implications for a wide variety of social phenomena. The great majority of this research has focused on the role of particular, clearly identified social categories (e.g. race, nationality, etc.) while ignoring or holding constant other identity dimensions. This approach has afforded considerable leverage for understanding how salient social identities influence perception, judgment, and behavior. However, it leaves unaddressed many questions about how particular social identities become salient and how (and whether) identities might be inferred when category membership is ambiguous or unknown. Everyday social perception often occurs under conditions of volatility (dynamic contexts), uncertainty (missing information), complexity (multiple bases for categorization), and ambiguity (unclear meaning of available cues). As a consequence, research must address how these factors might qualify basic processes of social categorization. Available evidence is reviewed, and directions for future research are discussed.     

The Relationship between Hoarding Symptoms,Intolerance of Uncertainty,and Error-Related Negativity

Individuals who hoard report poor tolerance for uncertainty. They also exhibit error-monitoring abnormalities and increased activation of the anterior cingulate during possession-relevant decision-making, potentially reflecting a context-dependent error sensitivity. Together, these underlying vulnerabilities may lead individuals who hoard to avoid uncertain acquiring and discarding decisions. The current study explored electrophysiological indices of error-monitoring (error-related negativity; ERN) in possession-related and possession-unrelated contexts, and how this related to self-reported intolerance of uncertainty (IU). Undergraduate students (N = 29) completed self-report measures of hoarding symptoms and intolerance of uncertainty, and then engaged in a Go/NoGo task and a novel Discard/NoDiscard task with concurrent EEG measurement. Regression analyses revealed that hoarding symptoms predicted ERN amplitude for possession-related errors but not possession-unrelated errors, and that this relationship was influenced by IU in possession-related contexts. These findings have theoretical implications for understanding vulnerability in hoarding.     

Explanations for racial discrimination: The effect of group discussion on intergroup attributions

Studied the effect of group discussion and racial group membership on attributions concerning the causes of racial discrimination. Twenty- four Black (mostly West Indian) and 24 White adolescents (age 16-19) were assigned in pairs to each cell of a 2 (Race of subject: Black/White) × 2 (Discussion/No Discussion) ‘mixed’ design. Each subject read four items exemplifying types of racial discrimination and attributed each to negative dispositions of Black people and/or discrimination by White authority figures (‘the system’). Subjects in the Discussion condition spent two minutes discussing each item prior to making their judgements. Ratings of ingroup and outgroup on eight attitudinal dimensions were also elicited, followed by a social distance measure. Multivariate analyses of variance revealed effects for racial group membership (p < 0.05) and group discussion (p < 0.05) on attributions. Further examination of the data by means of discriminant analyses indicated which items differentiate between the groups. Data based on the attitudinal ratings were also subjected to multivariate analyses and point to the positive group-image of the Black respondents and a lack of intergroup discrimination by the White subjects; the social distance scores of the latter subjects are, however, higher. Results are discussed in terms of the literature on group polarization and intergroup differentiation.     

Islamist terrorism as identity threat: the case of ambivalent identification and self‐stereotyping among Turkish Muslims

Terrorist attacks committed in 2003 by Turkish Islamist extremists threatened the social identity of Turkish Muslims by associating them with terrorism. Using a 2 × 3 experimental design, we categorized Turkish respondents and terrorists as members of a shared superordinate group (“Muslims”) or as members of separate subgroups. When sharing superordinate group membership with terrorists, less identified Turkish respondents experienced ambivalent identification, i.e., they sought to maintain attachment to their group while simultaneously seeking distance from it. Ambivalent identification was reduced when respondents emphasized their typicality as members of a Muslim subgroup that did not include terrorists. The discussion focuses on ambivalent identification as a response to identity threat, and the implications for Islamist terrorism for the social identity of Muslims.     

Employees’ work effort as a function of leader group prototypicality: the moderating role of team identification

The social identity model of organizational leadership (SIMOL; Hogg and van Knippenberg, 2003 was extended analyzing the degree of employees’ effort as individual outcome of leadership effectiveness. Two studies were conducted with Italian participants. Study 1 was a survey conducted with 68 employees of a medium size company. Results showed the significant two-way interaction effect of team identification × leader group prototypicality in predicting employees’ work effort. Study 2, including 124 students, was a 2 × 2 within subject design (team identification high vs. low × leader group prototypicality high vs. low) using scenarios. Results confirmed experimentally the causal relationship between such variables: subjects in condition of high team identification and high leader group prototypicality perceive leaders as more effective than the subjects in the other three conditions.     

Individual Versus Collective Responses to Membership in a Low-Status Group: The Effects of Stability and Individual Ability

Abstract

To test predictions of social identity theory (SIT; M. A. Hogg & D. Abrams, 1988; H. Tajfel & J. C. Turner, 1979) and the 5-stage model (FSM; D. M. Taylor & D. J. McKirnan, 1984) concerning reactions to membership in a low-status group, the authors led 112 pupils to believe that another (anonymous) class outperformed their class. In an overall permeable and legitimate intergroup context, the authors manipulated the stability of the low group status and the individual ability of the group members. Contrary to SIT and FSM, the pupils generally favored collective normative action. Individual mobility was preferred only by group members, especially boys, with high individual ability who thought that the low status of their group was stable. The results support FSM assumptions (a) that individual ability is a powerful determinant of intergroup behavior but (b) that one should consider its impact in combination with perceived stability.     

Can men do better if they try harder: Sex and motivational effects on emotional awareness

Research indicates that women are more emotionally aware than men. Motivation was investigated as a possible source of this sex difference. A total of 242 women and 74 men completed the first half of an emotional awareness test, the Level of Emotional Awareness Scale (LEAS; Lane & Schwarz, 1987), received either motivational or control instructions, and then completed the second half of the awareness scale. Participants' LEAS scores were compared via a 2 (sex) × 2 (condition) × 2 (time) General Linear Model Analyses of Variance. The motivational intervention was successful in significantly increasing both male and female participants LEAS scores, although women generally demonstrated greater emotional awareness than men. Furthermore, the LEAS scores of motivated men equalled those of women in the control condition, but the motivated men had to work significantly longer on the task to achieve this equality. Additional covar-iance analysis revealed that there were significant sex differences even after controlling for self-report and behavioural measures of motivation. We discuss the implications of these findings for understanding sex differences in emotional awareness.     

Complicating race: the relationship between prejudice, race, and social class categorizations

Although racial stereotyping and prejudice research have received considerable attention, the important element of social class has been largely excluded from social psychological research. Using the Statement Recognition Procedure, two experiments investigated social categorization along race and social class dimensions, the influence of racial and social class prejudice on these categorizations, and differences between White and Black perceivers. Analyses conducted at the subtype of race and social class memberships demonstrated differing patterns of categorization based on subtype membership. For example, lowerclass Black targets were primarily categorized by race, whereas middle-class Black targets were primarily categorized by social class. The results demonstrate the importance of considering social class membership independent of and in conjunction with race. Theoretical and methodological implications regarding the study for race and social class categorizations are discussed.     

Multiple categorization and implicit intergroup bias: differential category dominance and the positive–negative asymmetry effect

Two experiments explored the differential information processing that occurs when perceivers encounter multiple categorizable individuals. Participants were required to recall specific information from previously encountered bogus newspaper stories. Across two experiments it emerged that participants differentially recalled target attributes as a function of positive versus negative story context and multiple dimensions of group membership. Specifically, different dimensions of categorization were dominant for positive and negative evaluative domains. These findings provide an important qualification to the positive–negative asymmetry effect in intergroup discrimination when multiple dimensions of categorization are available. In addition, comparison of the observed effects in different cultural settings suggests the need to consider contextual influences when considering intergroup phenomena with real social group memberships. Finally, in line with previous work, a dissociation was observed between explicit and implicit measures of intergroup bias. The findings are considered within the wider context of work into social categorization and intergroup relations.. Copyright © 2001 John Wiley & Sons, Ltd.     

A Multi‐Method,Multi‐Hazard Approach to Explore the Uniqueness of Terrorism Risk Perceptions and Worry1

Developing ways to manage terrorism effectively requires a better understanding of how the public perceives this threat. In the present study, Canadians' perceptions of terrorism risk and 4 other hazards were assessed using a word‐association technique and rating scales reflecting key cognitive dimensions of risk (threat, uncertainty, control) and worry reactions. Data were collected in a national telephone survey. Canadians perceived terrorism as posing a lower threat, as more uncertain, and as less controllable, compared to the other hazards. Positive associations of perceived threat and of perceived uncertainty with worry about terrorism were observed. However, perceived control was unexpectedly positively associated with worry about terrorism. The findings also suggest that additional social contextual factors should be examined in future research.     

Validation,Persuasion and Recycling: Capitalizing on the Social Ecology of Newspaper Use

Two experiments used clinical validation to increase scrutiny of messages posted in public settings. The first experiment used a 2 (validation: no/yes) × 2 (persuasion: none/"it is important") factorial design to develop messages about newspaper recycling. The prompt (no validation/no persuasion) had little impact on newspaper recycling, but the other 3 signs all resulted in increased recycling while the signs were in place. After signs were removed, recycling remained significantly higher than baseline (marginally significant for validation/persuasion). At the end of the study, number of cognitions favoring recycling was significantly higher in the validation-only condition and was lower in the validation/persuasion condition. Experiment 2 tested whether signs would have more impact if they were sensitive to the social ecology of newspaper recycling; that is, readers' tendency to leave newspapers behind so others may read them. Messages based on a 2 (message: validation-only/validation plus persuasion) × 2 (ecology: no social ecology/social ecology) factorial design supported social ecology's importance. Furthermore, because of the increased sharing in the social ecology conditions, total numbers of newspapers used was significantly lower in those buildings. Validation only yielded sustained behavior change in both Experiments 1 and 2, supporting additional research on the question of whether validation can, by itself, lead to cognitive elaboration and self-persuasion.
