Children correlate infrequent behaviors with minority groups: a case of illusory correlation

Adults perceive an illusory correlation between negative social behaviors and membership in the smaller of two groups — the minority group (Hamilton & Gifford, 1976). Two experiments investigated the development of this illusory correlation. We created pictorial stimuli showing children performing good or bad behaviors. In Experiment 1 we told participants (children in grades 1, 3, 5, and 7 and adults) that each picture depicted a child from one of two groups. Group membership and behavior were uncorrelated, but, like adults, children perceived a correlation between the smaller group and negative behaviors. Children’s attributions of good and bad behaviors to the two groups showed a weak but significant bias. Their estimations of the number of children in each group who behaved badly showed a stronger bias. Children also rated the smaller group more negatively on many dimensions. Experiment 2 showed that the illusory correlation is not dependent on social stimuli. Children performed essentially the same tasks, but good and bad behaviors were replaced by the colors red and green, and the group members were represented as squares and triangles. The results were strikingly similar to those obtained with social stimuli. In both experiments, the strength of the illusory correlation did not vary significantly with age. The results are discussed from the perspective of theories that have been proposed to account for adult behavior and the implications of no developmental trend.     

Children's Illusory Correlations: The Role of Attentional Bias in Group Impression Formation

Two experiments examined 2nd and 5th graders' tendency to perceive illusory correlations between a minority group and infrequent behaviors. Experiment 1 examined perceptions of fictitious majority and minority groups in which 67% of each group's behaviors were positive and 33% were negative. Second and 5th graders formed illusory correlations between the minority group and negative behaviors on group attribution and frequency estimation tasks, and frequency estimations predicted differential evaluations of the majority and minority groups. Experiment 2 replicated findings from Experiment 1 under conditions in which 67% of the target groups' behaviors were negative and 33% were positive. In this case, children perceived an illusory correlation between the minority group and positive behaviors, and frequency estimations again predicted differential group evaluations. The results are discussed in terms of their implications for understanding judgment biases and stereotype formation and for stereotyping and prejudice interventions.     

Perceptions of and by minority groups: The case of women in academia

Thirty seven academics participated in a field study in which perceptions of the size and attributes of a majority and minority group were obtained. (The groups concerned were male and female academics at a British university). These observations were used to examine the phenomenon of illusory correlation, and to test hypotheses concerning the perceived homogeneity and competence of ingroup and outgroup in majority-minority contexts. To test for the illusory correlation effect estimates of the numbers of male and female senior staff were elicited. These estimates were consistently inaccurate, producing a lower perceived correlation between gender and seniority than actually existed. Measures of intragroup homogeneity revealed that, as predicted from previous research, members of the minority group saw their own group as more homogeneous than the outgroup. For majorty group members the reverse was true. The intergroup evaluations generally favoured the minority group; this was especially evident in the evaluations from the minority group members themselves. Possible explanations of these findings and their correspondence with those obtained from laboratory research are discussed.     

Crossed categorization effects on the formation of illusory correlations

This study investigates how stereotypes are formed and whether stereotype formation is reduced by the prevalence of multiple categorizations. Illusory correlations between the desirability of behaviours and two dimensions of social categorization, both containing a majority and a minority category, were assessed in single categorization and crossed categorization conditions. In the single categorization conditions, the usual illusory correlation in favour of the majority category was obtained. In the crossed condition, the combination of the two majority categories was positively discriminated from the remaining three combinations, while no differences were found among the latter. A source‐monitoring analysis of assignment frequencies replicated earlier findings that illusory correlations are due to an evaluative guessing bias, rather than to enhanced memory for individual instances of behaviour. The results show inconsistencies with a distinctiveness‐based and a social categorization account of illusory correlations, but they can be explained in terms of information loss.

Affect and stereotyping: the effect of induced mood on distinctiveness-based illusory correlations.

In 2 studies, the effects of mood on the formation of distinctiveness-based illusory correlations were examined. After exposure to stimuli inducing positive, neutral, or negative mood, Ss read information about behaviors performed by members of 2 groups in an illusory correlation paradigm. In both experiments, only Ss in a neutral mood formed illusory correlations. In addition, Experiment 2 assessed Ss' processing latencies as a means of investigating differential attention to distinctive behaviors. Only Ss in a neutral mood differentially attended to the minority group's infrequent behaviors. Induced mood apparently interfered with the processing necessary to differentially encode distinctive stimuli, undermining the illusory correlation effect.     

Examining differences in minority versus majority preschoolers on social categorization and perceived intergroup distance

We examined the differences between majority and minority children (i.e., group membership) on racial categorization and perceived cultural distance, among 4‐ to 6‐year‐old children, in low diversified schools. We used a spontaneous social categorization task using pictures of children from three different racial groups broadly represented in France (Europeans, Black‐, and North‐Africans), and an evaluation of the perceived cultural distance between participants' in‐group and the racial group represented in the picture, adapted to children and based on three factors (language, eating habits, and music). Results revealed an effect of age on racial categorization: the older the children, the more successful they are in this task. They showed a significant effect of the racial group represented in the photos on perceived cultural distance: members of minority groups (i.e., Black‐ and North‐Africans) were evaluated as more different compared to those of the majority group on each of the factors. Finally, we got an interaction between participants' in‐group and the racial group represented in the pictures, for the language factor: members of the majority group perceived as more different photographs representing minorities peers than those representing majority peers, while participants belonging to minority groups perceived no differences between photographs, according to the racial criteria.     

One-shot illusory correlations and stereotype formation

In four studies, the authors explored the emergence of one-shot illusory correlations--in which a single instance of unusual behavior by a member of a rare group is sufficient to create an association between group and behavior. In Studies 1, 2, and 3, unusual behaviors committed by members of rare groups were processed differently than other types of behaviors. They received more processing time, prompted more attributional thinking, and were more memorable. In Study 4, the authors obtained evidence from two implicit measures of association that one-shot illusory correlations are generalized to other members of a rare group. The authors contend that one-shot illusory correlations arise because unusual pairings of behaviors and groups uniquely prompt people to entertain group membership as an explanation of the unusual behavior.     

Ideology is related to basic cognitive processes involved in attitude formation

Ideological orientation shapes the perception of the social world and conservatism is associated to an increased weighting of negative over positive information. In the present work we explored how this ideology-based difference is also related to basic cognitive processes involved in attitude formation. In particular, we hypothesized that conservatives, as compared to liberals, would show stronger illusory correlation effects when negative information is relatively infrequent. In Study 1 we employed the typical illusory correlation paradigm (Hamilton & Gifford, 1976) and results confirmed the hypothesis: conservatives developed more negative impressions toward the minority group and showed consistent memory biases. In Study 2, positive information represented the infrequent dimension and in this case no ideology-based difference was observed. Overall, findings indicate that when exposed to numerically different novel groups and negative behaviors are infrequent, illusory correlation effects are accentuated among individuals embracing conservative rather than liberal views of the world. This result may help to understand why conservatives tend to form more negative attitudes toward social minorities.     

Intergroup relations in a changing political context: the case of veiled and unveiled university students in Turkey

The present study investigated (a) the underlying dimensions of different measures related to identification, categorization, ingroup bias and contact conditions; and (b) relations between two groups related to an important social controversy over time. Questionnaires were administered to veiled (minority) and unveiled (majority) Turkish female university students during the fall of 1996 and the spring of 1998. Results of factor analysis revealed three factors, namely: tolerance, including perceived outgroup homogeneity, ingroup bias, and individuation; identification, including identification and perceived ingroup homogeneity; and contact conditions, including ratings of pleasantness, frequency and feelings of anxiety. Comparison of groups over time revealed that although the minority group reported lower tolerance for outgroups than the majority the pattern was reversed in 1998. In addition, the majority reported greater negative contact conditions of contact in 1998 than in 1996. No time‐related differences were revealed for the minority with respect to reports of contact conditions. Results were discussed with respect to sensitivity of group relations to social context and to Social Identity Theory. Copyright © 2000 John Wiley & Sons, Ltd.     

Evidence for hypodescent and racial hierarchy in the categorization and perception of biracial individuals

Individuals who qualify equally for membership in two racial groups provide a rare window into social categorization and perception. In 5 experiments, we tested the extent to which a rule of hypodescent, whereby biracial individuals are assigned the status of their socially subordinate parent group, would govern perceptions of Asian-White and Black-White targets. In Experiment 1, in spite of posing explicit questions concerning Asian-White and Black-White targets, hypodescent was observed in both cases and more strongly in Black-White social categorization. Experiments 2A and 2B used a speeded response task and again revealed evidence of hypodescent in both cases, as well as a stronger effect in the Black-White target condition. In Experiments 3A and 3B, social perception was studied with a face-morphing task. Participants required a face to be lower in proportion minority to be perceived as minority than in proportion White to be perceived as White. Again, the threshold for being perceived as White was higher for Black-White than for Asian-White targets. An independent categorization task in Experiment 3B further confirmed the rule of hypodescent and variation in it that reflected the current racial hierarchy in the United States. These results documenting biases in the social categorization and perception of biracials have implications for resistance to change in the American racial hierarchy.     

Modifying perceived variability: four laboratory and field experiments show the effectiveness of a ready‐to‐be‐used prejudice intervention

We examined whether increasing individuals' perceived variability of an out‐group reduces prejudice and discrimination toward members of this group. In a series of four laboratory and field experiments, we attracted participants' attention to the heterogeneity of members of an out‐group (or not), and then measured their attitudes or behaviors. Perceived variability was manipulated by portraying the out‐group members as having diverse socio‐demographic characteristics and different personality traits and preferences. Prejudice and discrimination were measured in terms of self‐reported prejudice, stereotyping, in‐group bias, social distance, and willingness to do something for the minority group under consideration. In all experiments, perceived variability decreased prejudice and discrimination.     

IN-GROUP IDENTIFICATION AS A FUNCTION OF DEPERSONALIZATION, DISTINCTIVENESS, AND STATUS

Abstract— Artificial social categories were created in a laboratory context in order to test predictions regarding the relative importance of group size and status as determinants of in-group favoritism. Subjects were assigned to categories of "overestimator" or "underestimator" and were told that one category included a majority of college students while the other represented a minority. Prior to category assignment, half of the subjects had been given confidentiality instructions designed to make them feel highly depersonalized. Based on feedback about test performance, status differentials between the two estimation categories were introduced.
Consistent with predictions, there was a three-way interaction between depersonalization, in-group size, and in-group status as determinants of evaluative in-group bias on social trait ratings. Under control conditions (no depersonalization), group status and majority size both contributed to positive valuations of the in-group. Under the depersonalization condition, however, subjects valued minority group membership more than majority categorization, and the effect of status was eliminated.     

Dual identities in intergroup contact: Group status and size moderate the generalization of positive attitude change

To explore the effects of various categorization strategies on intergroup bias within and beyond a contact situation, two experiments were conducted involving groups of different size and/or status that worked together on a cooperative task. Three categorization strategies (decategorization, recategorization, and dual identity) were compared, and bias was measured through symbolic reward allocations to people who were and were not actually encountered. In Experiment 1 (N = 129), we varied group size (minority or majority) and found that it affected bias within the contact situation—minority groups were more biased than majority groups. All of the categorization strategies limited bias and they did so equally well. Outside the contact situation, however, only the recategorization and dual identity strategies limited bias. In Experiment 2 (N = 156), we varied both group status (low or high) and group size. Both of these variables affected bias within the contact situation—high status groups were more biased than low status groups, and minority groups were again more biased than majority groups. Once again, all three categorization strategies limited bias and they did so equally well. Outside the contact situation, however, an interaction among the independent variables was observed. For minority groups, only the dual identity strategy limited bias, but none of the categorization strategies limited bias for majority groups.     

Biased processing of stereotype-incongruency is greater for low than high status groups

Two studies assessed whether a stereotypic explanatory bias emerges primarily when members of low (compared to high) social status groups engage in behaviors inconsistent with group stereotypes. A preliminary study showed that male and female participants spontaneously showed more stereotypically biased explanatory processing of female stereotype-inconsistency (i.e., explanation of male-stereotypic behaviors performed by female compared to male actors) than male stereotype-inconsistency (i.e., explanation of female-stereotypic behaviors performed by male compared to female actors). The main experiment provided a manipulation of social status of target groups, and both external (i.e., situational) and internal (i.e., dispositional) explanations for stereotype-inconsistent behaviors were assessed. Results showed that external explanations for female stereotype-inconsistency were greater for targets described as low, not high in socioeconomic status. This research suggests that information processing is biased when members of a low status group engage in stereotype-inconsistent behaviors, whereas members of high status groups can engage in either stereotypic or counter-stereotypic behaviors without instigating biases in information processing.     

Representing ‘Us’ and ‘Them’: Building Blocks of Intergroup Cognition

Three experiments explored whether group membership affects the acquisition of richer information about social groups. Employing a minimal-groups paradigm, 6- to 8-year-olds were randomly assigned to 1 of 2 novel social groups. Experiment 1 demonstrated that immediately following random assignment to a novel group, children were more likely to generalize negative behaviors to outgroup members and positive behaviors to ingroup members and to report a preference for ingroup members. Experiments 2 and 3 showed that this initial ingroup-favoring bias interacts with subsequent learning, thereby attenuating the effect of negative information about the ingroup and enhancing the effect of negative information about the outgroup. These effects were more powerful with respect to preferences than induction: After hearing that some ingroup members behaved badly, children predicted that ingroup members would behave more negatively than outgroup members, but they did not express preferences for the outgroup over the ingroup. Together these data shed light on the construction of social category knowledge as well as the processes underlying the absence of own-group positivity among children from lower-status social groups.     

Creating distinct implicit and explicit attitudes with an illusory correlation paradigm

Two studies used an illusory correlation procedure to test whether distinct implicit and explicit evaluations can result from the same learning episode. All participants learned twice as much about the qualities of one group (majority) than another (minority). In one condition, the ratio of positive to negative information was equal between groups. In other conditions, the majority group showed proportionally more positive qualities than the minority group, or vice versa. Participants in the pro-majority and pro-minority conditions formed both implicit and explicit attitudes consistent with the attitude induction. Participants in the illusory correlation condition showed the expected preference for the majority group (the illusory bias), but showed no implicit preference, suggesting distinct influences on implicit and explicit attitude formation. The effects are consistent with dual-process models in which implicit attitudes reflect accounting of covariation and explicit attitudes reflect interpretative judgments of that covariation.     

On the immediate consequences of intergroup categorization: activation of approach and avoidance motor behavior toward ingroup and outgroup members

The present research argues that intergroup categorization has immediate behavioral consequences. Specifically, intergroup categorization is hypothesized to prepare the organism to respond differently to ingroup and outgroup members so that approach-like motor movements should be faster toward ingroup- versus outgroup-related stimuli. In contrast, avoidance-like behavior should be facilitated when reacting to outgroup versus ingroup members. Studies 1 and 2 test the basic hypothesis in relation to ethnic, national, age, and political categorization. Study 3 uses a minimal group paradigm to test the hypothesis in relation to newly formed groups. Across these experiments, participants were generally faster in performing approach-like motor movements toward ingroup members or avoidance behaviors toward outgroup members. The evolutionary function and the cognitive underpinnings of this state of "physical readiness" to approach ingroup and avoid outgroup members are discussed.     

Illusory correlation in the perception of performance by self or a salient other

Past research has shown that judges overestimate the degree of relative association between a salient group target and an infrequent behavior. However, judges also overestimate the degree of relative association between a salient individual target and a frequent behavior. The present study investigated judgments when either the self or a salient individual was one of the targets. Subjects either performed a knowledge task along with three other participants or they observed the performance of four participants, one of whom was made salient. The knowledge task was presented as either important or unimportant. In addition, in one condition, all the participants succeeded on 70% of the trials. In the other condition, all the participants failed 70% of the time. Results in the salient individual target condition replicated previous results, in that the salient target was perceived as more strongly associated with the frequent behavior than were the nonsalient targets. This pattern of illusory correlation was also obtained for the self, with one exception: When the self and the other participants predominantly failed and the outcome was important, no such illusory correlation was shown. The results are interpreted in terms of motivational processes that are engaged by threats to the self. These motivational processes counteract or supplant the cognitive biases that typically lead to the illusory correlation based on the perception of relatively greater association between a salient individual target and the frequent behavior. Results are discussed in terms of their relevance to self-perception processes, social comparison, and research on attributional biases.     

Group socialization and prejudice: the social transmission of intergroup attitudes and beliefs

In order to examine the social transmission of prejudice in the military, attitudes and beliefs of Francophone (minority) and Anglophone (majority) prospective military officers toward their own and other groups were assessed at the beginning and at the end of a four‐year officer‐training program. Consistent with social dominance theory and system justification theory, majority group members become significantly more negative toward outgroups (e.g. Francophones, civilians and immigrants) and more likely to internalize beliefs that legitimize the economic gap between Francophones and Anglophones in Canada. Moreover, as predicted on the basis of self‐categorization theory, the results show that identification with the category ‘Canadian Forces Officers’ assessed at the midpoint in the program, moderates the change in intergroup attitudes and beliefs. Finally, minority group members did not internalize negative stereotypes of their own group. These results provide important evidence for the role of group socialization in the explanation of intergroup attitudes and beliefs and suggest that social identification is a key factor in group socialization, consistent with self‐categorization theory.

Illusory Correlations in Perceptions of Obese and Hypertensive Patients’ Noncooperative Behaviors1

This research investigated perceived medical noncompliance between obese and hypertensive patients. An illusory correlation formed between obese patients and their noncooperative behaviors. Participants overestimated the frequency with which obese patients did not cooperate with their physician's advice when these patients appeared infrequently. When hypertensive patients appeared infrequently, however, participants were accurate in their estimates of noncooperation for these patients. These findings suggest that stigmatized patients suffer more from an illusory correlation bias than do nonstigmatized patients, and this effect is exacerbated when people have infrequent contact with stigmatized patients.
