On the asymmetry in the cognitive construal of ingroup and outgroup: A model of egocentric social categorization

A model of egocentric social categorization (ESC-model) is presented. It predicts an asymmetry in the cognitive construal of ingroups and outgroups which is traced back to an egocentrism in the cognitive differentiation of the social world. The more specific assumptions are: (1) At the most basic level of cognitive differentiation, the perceiver distinguishes between the categories ME and NOT-ME. (2) This basic level categorization predicates an asymmetry in the cognitive construal of ingroup and out-group as social categories: The ingroup is construed as a heterogeneous aggregate of separate entities and the outgroup as a homogeneous social category. (3) Egocentric social categorization thus facilitates self-definition in terms of personal identity relative to self-definition in terms of social identity. The ESC-model is highly relevant to research on perceived ingroup and outgroup homogeneity. Moreover, it alerts researchers to the possibility of ‘quasi-intergroup’ situations in which the outgroup, but not the ingroup, is a salient entity. This article also discusses the relationship between the ESC-model and self-categorization theory and points out some prospects for future research.     

Crossed categorization versus simple categorization and intergroup evaluations: a meta‐analysis

Crossed categorization typically refers to the crossing of two dichotomous social dimensions, resulting in four groups (double‐ingroup, two mixed groups, and double‐outgroup). This paper reports the results of a meta‐analysis comparing the effects of crossed categorization on intergroup evaluations with the effects of simple categorization on intergroup evaluations. The crossed categorization paradigm is shown to increase or decrease ingroup bias, depending on how ingroup bias is defined in the crossed categorization paradigm. Moreover, just as in simple categorization, ingroup bias in crossed categorization is shown to be greater when the proportionate size of the ingroup is smaller. However, contrary to the patterns established in simple categorization, the reality of the group categorizations does not increase ingroup bias in crossed categorization. We discuss the implications of these results for future research on intergroup evaluations. Copyright © 2001 John Wiley & Sons, Ltd.     

Uncovering the diverse cultural bases of social identity: Ingroup ties predict self‐stereotyping among individualists but not among collectivists

On what basis do people form their social identities? To investigate this issue, the present research investigates cross‐cultural differences in self‐stereotyping, a key outcome of social identification. In particular, the research tests the hypothesis that ingroup ties are a stronger predictor of self‐stereotyping among people from individualist cultures than among people from collectivist cultures. In Study 1, university students (N = 117) completed measures of ingroup ties and self‐stereotyping with respect to an intimacy group (family and friends). Consistent with predictions, ingroup ties significantly predicted self‐stereotyping among individualists but not among collectivists. Study 2 (N = 104) found a similar pattern of results among members of the global internet community who considered either an intimacy group (their friends), a task group (their work group) or a social category (their gender). These results indicate that people in individualist cultures are more likely than those in collectivist cultures to base their social identities on ingroup ties. The implications of these results are discussed in relation to self‐categorization theory's depersonalization account of social identification.     

Ingroup bias in the minimal group paradigm shown by three‐person groups with high or low state self‐esteem

From social identity theory a negative relation between self‐esteem and ingroup bias can be deducted. Much research has been done to test this proposition and largely failed to confirm this relation. Unlike many existing studies, we conducted an experiment in which (a) self‐esteem is not conceived as a trait entity but much more situation‐specific, (b) the self‐esteem manipulation is not relative to the outgroup, and (c) the measure of intergroup differentiation is unrelated to the self‐esteem manipulation. We categorised our participants into two arbitrary minimal groups (Klee or Kandinsky fans) and afterwards formed homogeneous three‐person groups (all persons were either Klee or Kandinsky fans). We manipulated the state self‐esteem of these real groups by giving them positive or negative feedback concerning their performance in a problem‐solving task. Afterwards, all groups distributed money to ingroup and outgroup members via Tajfel distribution matrices. Low state self‐esteem groups were found to exhibit stronger ingroup bias than high state self‐esteem groups overall, although the variability of intergroup discrimination was larger in the low state self‐esteem groups, pointing to more heterogeneous reactions to low state self‐esteem.

A Self‐Categorization Explanation for Opinion Consensus Perceptions

The public expression of opinions (and related communicative activities) hinges upon the perception of opinion consensus. Current explanations for opinion consensus perceptions typically focus on egocentric and other biases, rather than functional cognitions. Using self‐categorization theory we showed that opinion consensus perceptions flow from cognitions regarding the fit between issues and group prototypes. Strong normative fit enhanced perceptions of ingroup opinion consensus (Experiments 1 and 2), and consensus perceptions varied as a function of comparison outgroups (Experiment 3), ingroup prototype salience (Experiment 4), and levels of identity threat (Experiment 5). Self‐categorization theory has the potential to integrate a variety of cognitive and motivational processes to provide a comprehensive explanation for opinion consensus perceptions.     

Categorization and intergroup anxiety in contact between British and Japanese nationals

Two studies examined the relationship between categorization, intergroup anxiety and intergroup attitudes (intergroup bias and negative affect). Study 1 consisted of a survey of 236 British and Japanese nationals. Study 2 was a longitudinal study of 54 Japanese students studying in the UK. Of the three categorization variables (interpersonal, superordinate and intergroup), only intergroup categorization was shown to have a relationship to generalized intergroup attitudes. In addition, intergroup anxiety and quality of contact were associated with ingroup bias and negative affect to the outgroup. Study 2 revealed an interaction between intergroup categorization and quality of contact in predicting negative affect. Intergroup anxiety was also associated with increased intergroup categorization. It is concluded that the effects of categorization during contact are still poorly understood, and that intergroup anxiety is a far more powerful variable in contact than the current literature acknowledges.

Friend or foe? Ingroup identification moderates reactions to outgroup members' allocation behavior

In the present article we build on previous work suggesting that people react more strongly to the favorability of outgroup authority allocations than ingroup authority allocations. Based on theorizing and research on intergroup perception and self‐categorization, we refine this argument by suggesting that responses to outgroup authorities depend on people's level of ingroup identification. We present data from an experiment showing that the favorability of treatment by an outgroup member primarily influences decision acceptance among high (vs. low) ingroup identifiers. In line with theory and research based on the relational model of authority, findings of the present study also suggest that ingroup identification has a reversed effect on acceptance of an ingroup authority's decisions. Specifically, the favorability of treatment by an ingroup member primarily influences decision acceptance among low (vs. high) ingroup identifiers. Copyright © 2006 John Wiley & Sons, Ltd.     

Ingroup bias,self-enhancement and group identification

These two studies integrate self-enhancement and ingroup bias and analyse the phenomena from the social identity theory and self-categorization theory. In Study 1, the subjects (N=181) evaluated supporters of two presidential candidates on a rating scale. In Study 2, the subjects (N=302) evaluated either Finnish women's and men's positive characteristics (success condition) or negative characteristics (failure condition) which might play a role in achieving equality between the sexes in Finland. Self-evaluations were conducted on the same scale as those of ingroup and outgroup evaluations. The results showed that ingroup was evaluated more positively than outgroup (hypothesis 1) and that self was evaluated more positively than ingroup (in Study 2, however, this main effect was qualified by gender). As expected, group identification did not dilute self-enhancement (hypothesis 2) in either of the studies but strengthened self-enhancement in Study 1. Hypothesis 3 stated that self-enhancement is inversely related to ingroup favouritism but the hypothesis was only partially confirmed in that the correlation was predictably negative in Study 1 but near zero in both conditions of Study 2. Finally, contrary to hypothesis 4, it turned out that high identified group members evaluated self and ingroup more independently than lows which contradicts the idea of depersonalization. Together the results would be plausible if we rejected the unidimensional conception of interpersonal–intergroup behaviour and assumed instead that interpersonal and intergroup behaviour constitute two bipolar continua. © 1997 by John Wiley & Sons, Ltd.     

Social Categorization in Intergroup Contexts: Three Kinds of Self‐Categorization

In reviewing self‐categorization theory and the literature upon which it is based, we conclude that individuals' attempts to form social categories could lead to three kinds of self‐categorization. We label them intergroup categorization, ingroup categorization, and outgroup categorization. We review literature supporting these three types and argue that they can help to explain and organize the existing evidence. Moreover, we conclude that distinguishing these three kinds of self‐categorization lead to novel predictions regarding social identity, social cognition, and groups. We offer some of those predictions by discussing their potential causes (building from optimal distinctiveness and security seeking literatures) and implications (on topics including prototype complexity, self‐stereotyping, stereotype formation, intergroup behavior, dual identity, conformity, and the psychological implications of perceiving uncategorized collections of people). This paper offers a platform from which to build theoretical and empirical advances in social identity, social cognition, and intergroup relations.     

Sources of respect: the effects of being liked by ingroups and outgroups

We investigated the effects of ingroup and outgroup sources of respect, defined as positive social evaluations of self, on group members' emotional reactions and collective self‐esteem. We used both natural group memberships (Studies 1 and 2) and laboratory groups (Study 3). We expected that the positive effects of respect derived from an ingroup would not hold when derived from an outgroup source. In Study 1 (N = 294) respect was manipulated as deriving either from ingroup or outgroup. Although respect produced a positive emotional reaction irrespective of source, collective self‐esteem was only enhanced by an ingroup source. In Study 2 (N = 248), we investigated the concurrent effects of ingroup respect and outgroup respect. As in Study 1, ingroup and outgroup respect both produced positive emotional reactions, but collective self‐esteem was only affected by ingroup respect. Additionally, outgroup respect intensified the shame people experienced due to lack of ingroup respect. In Study 3 (N = 66), participants were immersed in experimental groups and ingroup and outgroup respect were manipulated orthogonally. Interactive effects of the two sources of respect indicated that high outgroup respect could not compensate for low ingroup respect, and if anything had an adverse effect.

The importance of social structure and social interaction in stereotype consensus and content: is the whole greater than the sum of its parts?

This paper addresses the hypothesis derived from self‐categorization theory (SCT) that the relationship between groups and stereotyping will be affected by the social structural conditions within which group interaction occurs. A mixed design experiment (n=56) measured low‐status groups' stereotypes and preferences for conflict with a high‐status outgroup prior to and after within‐group discussion across varying social structural conditions. Over time, participants in [open] conditions consensualized around positive conceptions of the outgroup and endorsed acceptance of their own [low status] position. However, in [closed] conditions participants consensualized around positive conceptions of the ingroup, negative conceptions of the outgroup, and tended towards preferences for collective protest. It is argued that the data support S‐CT's contention that stereotyping and group processes are fundamentally interlinked and that neither can be properly understood in isolation from the dynamics of the surrounding intergroup context.

Cognitive differentiation between self,ingroup, and outgroup: The roles of identification and perceived intergroup conflict

Several models predict that persons ascribe opposite characteristics to self and ingroups on the one hand and outgroups on the other (outgroup contrast). However, only few studies have found this effect. This study explored its boundary conditions. Sixty‐two students rated (a) characteristics of themselves, an ingroup (own study major), and an outgroup (other study major), (b) ingroup identification, and (c) perceived intergroup conflict. Participants who were relatively high in ingroup identification and who perceived relatively high levels of intergroup conflict displayed outgroup contrast, as indicated by negative correlations between trait ratings for self and ingroup and between trait ratings for ingroup and outgroup. The other participants showed weaker or no outgroup contrast. Thus, this study is one of the few empirical demonstrations of outgroup contrast and points to moderators that should be considered in future research on this effect.

How intergroup friendship works: A longitudinal study of friendship effects on outgroup attitudes

Cross‐sectional research has shown that frequency of self‐disclosure to outgroup members mediates the positive relationship between intergroup friendship and outgroup attitudes. The current research investigated the relationship between self‐disclosure and attitudes in more depth. New undergraduate students were asked to nominate an ingroup or outgroup friend and then report the intimacy of their disclosures to them, their anxiety and attitudes towards a series of social groups, in the first week of the semester and 6 weeks later. Intimacy of disclosure predicted more positive attitudes towards outgroups over time, but this association was only found among participants who nominated an outgroup friend. In the ingroup friend condition, a negative association was found. These associations were mediated by general intergroup anxiety. These relationships highlight the importance of integrating theories of interpersonal and intergroup relations when investigating intergroup contact. Copyright © 2011 John Wiley & Sons, Ltd.     

Accessibility and fit as determinants of the salience of social categorizations

The present article proposes a theoretical model of factors affecting the salience of social categorizations. The model is strongly related to the accessibility×fit formulation by Bruner (1957) and to Oakes' (1987) functional perspective on category salience. The results of an experimental series using the ‘Who said what?’ paradigm are presented, which examined several hypotheses derived from the model. In Study I it was shown that the salience of a social categorization with high chronic accessibility (sex categorization) was related to perceptions of issue relevance (normative fit) and intercategory differences (meta‐contrast ratio). Furthermore, in line with the salience model measures to increase the situational accessibility, (i.e. a priming procedure) of categorizations with low chronic accessibility (educational group and home town categorizations) failed to affect category salience as long as participants perceived no comparative and normative fit of these categorizations (Study II). Under conditions where comparative fit of these categorizations was perceived, however, the priming procedure successfully enhanced category salience (Studies II and III). Results are largely consistent with the hypotheses derived from the salience model and support Oakes' functional approach to category salience. Finally, the complex interrelation between situational accessibility and perceived fit will be discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

Perceptions of social influence when messages favour ‘us’ versus ‘them’: A closer look at the social distance effect

The third‐person effect (TPE) is the tendency for individuals to assume that persuasive communications have a stronger effect on other people than on themselves. In turn the social distance effect (SDE) is the tendency for this TPE to increase with the psychological distance between self and comparator. Two experiments showed that the SDE is moderated by whether the message favours the ingroup or the outgroup, holding all other content constant. In Study 1, male and female participants read a message arguing that either women were better drivers than men or vice versa, and then indicated how much they thought themselves, ingroup members, outgroup members and society would be influenced. The results indicate that for the pro‐outgroup message the SDE was found. However, for the pro‐ingroup message the SDE was reversed with ingroup members perceived as more influenced than all other targets, including the self. Study 2 replicated this finding using minimal groups, which eliminated the effects of prior stereotypes about male and female drivers. Across both studies the self was perceived as relatively invulnerable to influence regardless of message bias. Copyright © 2006 John Wiley & Sons, Ltd.     

Inter‐category versus intra‐category fit: when social categories match social context

The goal of the research reported in this article was to examine whether social categorization, commonly thought to be a function of accessibility and intra‐category fit, is also sensitive to changes in inter‐category fit. Intra‐category fit refers to the match between a target person's features and stored categorical knowledge, inter‐category fit to the extent to which category memberships and targets' features covary across perceived group members. In Experiments 1, 2, and 3, members of social categories of low, medium, and high accessibility, respectively, were shown in a group discussion. Inter‐category fit was manipulated in three steps. Category salience in memory increased as an additive function of accessibility and inter‐category fit. Experiment 4 replicated the effects of inter‐category fit while intra‐category fit and the information presented for individual discussants were held constant. The present studies are the first to demonstrate an effect of inter‐category fit on a relatively direct measure of spontaneous social categorization. Copyright © 2004 John Wiley & Sons, Ltd.     

Group polarization and choice‐dilemmas: how important is self‐categorization?

Self‐categorization proponents (e.g., Turner, 1991 ) assume that group polarization occurs because discussants wish to differentiate themselves from outgroup positions and implicitly think of such groups even when they are not specifically mentioned. Ingroup/outgroup salience is thought to heighten such effects. To examine this view, we had participants discuss Choice Dilemma items either with or without explicit knowledge of outgroup positions. Contrary to a self‐categorization account, this manipulation of outgroup salience did not affect the degree of group polarization. In addition, rating measures revealed little spontaneous consideration of outgroup positions on the part of participants, nor was consideration of outgroup positions related to degree of polarization. Group members did show evidence of ingroup identification, but this identification was unrelated to participants' post‐discussion conformity to the group consensus. Taken as a whole, these results suggest distinct limits to the self‐categorization interpretation of group polarization involving Choice Dilemmas. Copyright © 2006 John Wiley & Sons, Ltd.     

Minority influence and social categorization

In this article, a theoretical distinction is proposed between representative outgroup minorities (representative of a minority category in the society, e.g. gays) and dissident outgroup minorities (defined as a minority subgroup within a larger outgroup category). Two studies are reported comparing the social influence of dissident outgroup minorities with that of ingroup minorities (belonging to the subject's own social category). It was predicted that a position advocated by a dissident outgroup minority would be more readily accepted than that of an ingroup minority, but that the ingroup minority would be more likely to elicit the generation of new, alternative solutions. A first experiment in which subjects were either exposed to an ingroup minority, an outgroup minority, or no influence source confirmed these predictions. In a second experiment, subjects were either exposed to a majority or to a minority source either belonging to the subject's own social category or to the outgroup. The results indicate that the position of an ingroup majority was readily accepted whereas the otherwise identical message of an outgroup majority was rejected; neither ingroup nor outgroup majority stimulated the development of alternative proposals. Again, in line with Nemeth' (1986a) theory, the position of an ingroup minority was rejected but stimulated the generation of new, alternative proposals. The differential role of social category membership in minority and majority influence and the applicability of Nemeth' (1986a) theory to the attitude change area are discussed.
