The ingroup overexclusion effect: Identity concerns in decisions about group membership

There are circumstances in which one is reluctant to express a judgment on the basis of the available information. This is for instance the case when the decision may jeopardize the integrity of the group one is a member of. In particular, ingroup members are considered less judgeable than outgroup members. This phenomenon corresponds to the ingroup overexclusion effect (Leyens and Yzerbyt, 1992). An experimental situation was designed in order to rule out an explanation of this phenomenon in terms of confirmation of hypothesis. French- or Dutch-speaking subjects heard recordings of 40 sentences and, depending on the specific wording of the question, decided whether the speakers belonged to the group of French-speaking (i.e. Walloon) versus Dutch-speaking (i.e. Flemish) Belgians or not. The 40 sentences enabled to cross three factors with five sentences in each cell: Walloon versus Flemish speakers, French versus Dutch sentences, and short versus long sentences. As predicted, subjects made most errors when ingroup members read short outgroup sentences. Most importantly, the specific wording of the question did not lead to a reversal of the pattern of errors of group identification. Subjects also took longer to make a decision about an ingroup member reading an outgroup sentence than about an outgroup member reading an ingroup sentence. Such a pattern clearly supports a motivational explanation and undermines a confirmation of hypothesis explanation of the ingroup overexclusion effect. Older accounts of ethnic identification phenomena are addressed and it is suggested that identity concerns greatly affect impression formation processes.     

The effect of exemplar activation on mental representations of the ingroup: the moderating role of relative ingroup size

The current research explores the effects of exemplars on the stereotype representation of one's ingroup. Previous research demonstrated that exposure to an ingroup exemplar affects the stereotype one holds of one's ingroup (Coats & Smith, 1999). The primary purpose of the present study was to examine whether this effect is moderated by relative ingroup size. Participants were placed into either a minority or majority group situation and exposed to 1 of 2 dissimilar exemplars of their ingroup. Later, they rated their ingroup. Ratings of the ingroup differed between exemplar conditions in unexpected ways, indicating that the exemplar affected participants' stereotype of their ingroup. Furthermore, exemplars had a stronger effect on participants in the minority group than those in the majority group. Finally, relative ingroup size and, to a marginal extent, exemplars were found to affect ratings of ingroup variability.     

The loyal member effect: on the preference for ingroup members who engage in exclusive relations with the ingroup

The goal of this article was to investigate an indirect form of intergroup differentiation in children in the context of racial attitudes: the preference for ingroup members who interact positively with other ingroup members rather than with outgroup members. Study 1 confirmed this general hypothesis with preschool and 1st-grade children, demonstrating that respondents preferred the ingroup member who played only with other ingroup members, evaluated this child more positively, and felt more similar to him or her. Studies 2 and 3 tested the boundary conditions of the phenomenon. Study 4 analyzed developmental changes demonstrating that the effect is no longer observed among 9- to 11-year-old children. Overall, these studies suggest that engaging in positive interactions with the outgroup might have its costs in terms of a relative devaluation and rejection by one's peers. Results are discussed by stressing the importance of intragroup processes for the regulation of intergroup relations among very young children.     

Leader-focused search: The impact of an emerging preference on information search

This article examines the influence an emerging preference (i.e., a leader) has on predecisional information search. We explore two possibilities. First, decision makers may seek information they expect will support their leader (leader-supporting search). Second, decision makers may seek information about their leader, irrespective of the expected valence of the information (leader-focused search). Across various studies, product domains and experimental designs, we consistently find that decision makers engage in leader-focused search, not leader-supporting search. We also find that leader-focused search can steer decision makers towards information sources that are less important, less credible, and objectively suboptimal.     

The effects of ingroup and outgroup homogeneity on ingroup favouritism,stereotyping and overestimation of relative ingroup size

An experiment (n = 61) investigated the effects of ingroup and outgroup homogeneity on ingroup favouritism, stereotyping and the overestimation of relative ingroup size. As predicted, outgroup homogeneity was conducive to ingroup favouritism. Ingroup homogeneity, however, failed to influence ingroup favouritism. Also unexpectedly, asymmetry in group homogeneity — irrespective of whether the ingroup or the outgroup was the more homogeneous group — led to pronounced stereotyping of both groups and to the overestimation of relative ingroup size.     

We are one and I like it: The impact of ingroup entitativity on ingroup identification

It is argued that the entitativity of the ingroup moderates the level of identification with the ingroup. Specifically, that high levels of entitativity are conducive to strong identification, whereas low levels of entitativity reduce identification with the ingroup. These hypotheses were tested across four studies using the European Union (EU) as the reference group. The four studies manipulated four different factors that, according to Campbell (1958), impact on group entitativity: common fate (Study 1), similarity (Study 2), salience (Study 3), and boundedness (Study 4). Across the four studies, we found evidence for the impact of these factors on the level of identification with the EU among European citizens holding moderate attitudes toward the EU but not (or much less) for citizens holding more extreme attitudes towards the EU. Mediational analyses further confirmed the viability of an entitativity‐based interpretation of the impact of the manipulations on the level of identification. The findings are discussed in light of the current debate on the concept of entitativity, the motives for social identification, and the reduction of ingroup bias.

Remembering things that never occurred: the effects of to-be-forgotten stereotypical information

Participants, 68 female and male nonpsychology university students, studied stereotypical and nonstereotypical words either with an initially activated social category (immigrant prime) or with no social category (neutral prime). They were then instructed to either forget or remember the studied words. This was followed by a recognition test. Based on the Deese-Roediger-McDermott (DRM) paradigm and stereotype-accessibility research, we anticipated that the participants in the immigrant, but not in the neutral, prime condition would falsely recognize more nonstudied stereotypic attributes under a forget than a remember instruction. The results supported our hypothesis. Implications of the outcome for eyewitness testimony, juridical decision-making, and stereotype maintenance are discussed.     

The influence of social consensus information on intergroup attitudes: the moderating effects of ingroup identification

Two studies examined the role of ingroup identification in the influence of social consensus information (information about others' beliefs) on intergroup attitudes. Research demonstrates that consensus information influences individuals' intergroup attitudes. However, the extent to which individuals identify with the group providing consensus information seems important to understanding consensus effects. In Study 1, 100 high or low ingroup identifiers received information that other ingroup members held favorable or unfavorable attitudes toward African Americans and then provided their own attitudes. In Study 2, 250 participants completed an ingroup identification manipulation (high, low, or control) before receiving favorable or no consensus information. Results of both studies demonstrated that ingroup identification moderated consensus effects, such that high identifiers were more susceptible to others' beliefs than individuals in the low identification and control conditions. In determining critical factors involved in consensus effects, we hope to create a useful method to promote favorable intergroup attitudes and behaviors.     

Mood and the impact of individuating information on the evaluation of ingroup and outgroup members: The role of mood-based expectancies

This research investigates the role of mood-based expectancies regarding a target's group membership for the impact of individuating information on target judgments. We argue that target judgments in both positive and negative mood may be more or less affected by individuating information depending on whether the target is an ingroup member or an outgroup member. Specifically, in a competitive intergroup setting it should be less congruent with mood-based expectancies when individuals in positive (negative) mood learn that an outgroup (ingroup) member rather than an ingroup (outgroup) member has succeeded. Hence, unexpected (i.e., mood-incongruent) category information should elicit more attention than expected (mood-congruent) category information. More importantly, subsequent individuating information (high vs. low target competence) should be processed more effortful and influence target judgments more strongly given mood-incongruent (vs. mood-congruent) category membership. Findings of an experiment support these predictions. Results are discussed in regard to implications for different research domains.     

The effect of comparative context upon stereotype content: children's judgments of ingroup behavior

This study addresses self-categorization theory's contention that stereotype content varies as a function of the comparative context within which a given group is considered. A sample of 5-, 7- and 10-year-old children (n = 192) made judgments about gender ingroup behavior in one of two comparative contexts: either adults of the same sex as self or children of the opposite sex. Specifically, judgments were either of the perceived stereotypicality or central tendency of 12 types of behavior. Both types of judgment were found to differ as a function of comparative context in ways predicted by self-categorization theory. However, contrary to prediction, there was no effect of age on the extent of stereotype variability.     

The impact of risk and affect on information search efficiency

We develop and test a theoretical framework of the joint influence of risk and affect on information search efficiency. Our framework proposes that information search is less efficient (i.e., less strategic) when risk is high, versus low. It further proposes that the influences of positive and negative affect on search efficiency are asymmetric and depend on the level of risk. Negative affect improves search efficiency when risk is high, but not when it is low. Positive affect degrades search efficiency when risk is low, but not when it is high. We find results consistent with our framework in two experiments. We discuss implications for affect research and for decision making in risky contexts, including financial statement auditing.     

The two faces of dominance: The differential effect of ingroup superiority and outgroup inferiority on dominant-group identity and group esteem

The present paper provides evidence that dominant-group members distinguish dominance framed as ingroup superiority from dominance framed as outgroup inferiority, and that ingroup superiority enhances esteem for, and thus identification with, the group more than outgroup inferiority. In Experiment 1, Democrats report higher levels of party identification after being told that Democrats won an election than after being told that Republicans lost the election. These effects are attenuated among dominant group members whose values are in conflict with how dominance was achieved. In Experiments 2a and 2b, unearned dominance framed as ingroup superiority resulted in higher levels of White identification than unearned dominance framed as outgroup inferiority among Whites who did not value meritocracy. In contrast, Whites who valued meritocracy did not increase their levels of identification with the group. In Experiment 2b, this interactive effect on racial identification was mediated by esteem for the group.     

The debiasing effect of counterfactual mind-sets: Increasing the search for disconfirmatory information in group decisions

We hypothesized that the activation of a counterfactual mind-set minimizes decision errors resulting from the failure of groups to seek disconfirming information to test an initial hypothesis. To test this hypothesis, we conducted two experiments examining the decision making processes of groups. The task for both experiments was modeled after the Space Shuttle Challenger disaster, and groups had to actively seek disconfirmatory information to make a correct decision. Prior to beginning the group decision making task, groups were exposed to one of two pre-task scenarios in which the salience of counterfactual thoughts was manipulated. In Experiment 1, groups in the counterfactual prime condition were significantly more likely to make the correct decision than groups in the non-counterfactual prime condition. In Experiment 2, we replicated the effect of counterfactual primes on decision accuracy and demonstrated that groups in the counterfactual prime condition were more likely to seek disconfirmatory information than groups in the non-counterfactual prime condition. We also conducted mediation analyses that clarify the decision making process. Implications for group decision making are discussed.     

Information search and decision making: The effects of information displays

Information display boards may be used to test assumptions about underlying cognitive processes in decision situations. However, the question may be raised whether information processing in a complex decision situation is indepemdent of the structure of the information display board used. In a study employing 96 subjects, the design of the information display board, the number of alternatives, and the number of attributes were varied. Twelve groups of eight subjects were presented with one hypothetical choice among riskless multiattribute decision alternatives (apartments). Results showed that information search patterns were not influenced by the design of the information display board, but that the relative number of attributes included in the decision process was. The number of available attributes appeared to be the strongest determinant of information search patterns. A higher number of attributes induced information search patterns consistent with the noncompensatory conjunctive decision rule. It is suggested that the decision situation employed, which forced the decision maker to remember each piece of information acquired, underlies the difference between the results in the present study and previous findings.     

The excess choice effect: The role of outcome valence and counterfactual thinking

Contrary to economic theory, psychological research has demonstrated increased choice can undermine satisfaction. When and why this ‘excess choice effect’ (ECE) occurs remains unclear. Building on theories of counterfactual thinking we argue the ECE is more likely to occur when people experience counterfactual thought or emotion and that a key trigger is a negative versus positive task outcome. Participants either selected a drink (Experiment 1) or chocolate (Experiment 2) from a limited (6) versus extensive (24) selection (Experiment 1) or were given no choice versus extensive (24) choice (Experiment 2). In both experiments, however, the choice was illusory: Half the participants tasted a ‘good’ flavour, half a ‘bad’ flavour. As predicted, extensive choice was only detrimental to satisfaction when participants tasted the ‘bad’ drink or chocolate, and this was mediated by the experience of counterfactual thought (Experiment 1) or emotion (Experiment 2). When outcomes were positive, participants were similarly satisfied with limited versus extensive and no choice versus extensive choice. Implications for our theoretical understanding of the ECE and for the construction of choice architectures aimed at promoting individual satisfaction and well‐being are discussed.     

The black sheep effect: Judgmental extremity towards ingroup members in inter-and intra-group situations

Two experiments yielded further evidence for the black sheep effect (Marques, Yzerbyt and by ens, 1988). In the first experiment, 66 subjects were presented with two good or two poor speeches, one supposedly made by an ingroup member and the other supposedly made by an outgroup member. In the second experiment, 37 subjects were presented with one good and one poor speech supposedly made either by two ingroup members or by two outgroup members. The black sheep effect was predicted and found in both experiments: subjects over-evaluated likeable ingroup members and under-evaluated unlikeable ingroup members as compared to equally likeable and unlikeable outgroup members. Collapsing the data of the two experiments suggests that social comparison may be performed, in purely symbolic terms, against a cognitive standard of positivity rather than an outgroup present in the judgmental situation. The emergence of the predicted effect when strongly individualized information was presented in inter- as well as in intra-group situations supports the robustness of the black sheep effect.
