A Decade of System Justification Theory: Accumulated Evidence of Conscious and Unconscious Bolstering of the Status Quo

Most theories in social and political psychology stress self-interest, intergroup conflict, ethnocentrism, homophily, ingroup bias, outgroup antipathy, dominance, and resistance. System justification theory is influenced by these perspectives—including social identity and social dominance theories—but it departs from them in several respects. Advocates of system justification theory argue that (a) there is a general ideological motive to justify the existing social order, (b) this motive is at least partially responsible for the internalization of inferiority among members of disadvantaged groups, (c) it is observed most readily at an implicit, nonconscious level of awareness and (d) paradoxically, it is sometimes strongest among those who are most harmed by the status quo. This article reviews and integrates 10 years of research on 20 hypotheses derived from a system justification perspective, focusing on the phenomenon of implicit outgroup favoritism among members of disadvantaged groups (including African Americans, the elderly, and gays/lesbians) and its relation to political ideology (especially liberalism-conservatism).     

I am against us? Unpacking cultural differences in ingroup favoritism via dialecticism

The authors proposed a novel explanation for cultural differences in ingroup favoritism (dialecticism) and tested this hypothesis across cultures/ethnicities, domains, and levels of analysis (explicit vs. implicit, cognitive vs. affective). Dialecticism refers to the cognitive tendency to tolerate contradiction and is more frequently found among East Asian than North American cultures. In Study 1, Chinese were significantly less positive, compared to European Americans, in their explicit judgments of family members. Study 2 investigated ingroup attitudes among Chinese, Latinos, and European Americans. Only Chinese participants showed significant in-group derogation, relative to the other groups, and dialecticism (Dialectical Self Scale) was associated with participants' in group attitudes. Study 3 manipulated dialectical versus linear lay beliefs; participants primed with dialecticism showed more negative, explicit ingroup attitudes. Although ingroup disfavoring tendencies were more prevalent among Chinese across studies, they may be a reflection of one's culturally based lay beliefs rather than deep-rooted negative feelings toward one's ingroup.     

Evidence for the underestimation of implicit in-group favoritism among low-status groups

We question the evidence and the reasoning underlying recent research suggesting that members of low-status groups often fail to show in-group favoritism at the implicit level. Specifically, we argue the predominant measure revealing this pattern of group attitudes (the IAT) is influenced by extrapersonal associations, just the sort of information that would lead low-status groups to appear not to prefer their in-group. In the research reported here, respondents from low-status groups (African-Americans in Study 1 and homosexual males in Study 2) exhibited no in-group favoritism on the standard IAT, replicating previous research. However, reliable in-group favoritism by members of both groups was revealed on a personalized IAT [Olson, M. A., & Fazio, R. H. (2004). Reducing the influence of extrapersonal associations on the Implicit Association Test: Personalizing the IAT. Journal of Personality and Social Psychology, 86, 653-667] that reduces extrapersonal influences. We also rule out the possibility that differential error rates can account for the different patterns observed on the two versions of the IAT.     

Why men (and women) do and don't rebel: effects of system justification on willingness to protest

Three studies examined the hypothesis that system justification is negatively associated with collective protest against ingroup disadvantage. Effects of uncertainty salience, ingroup identification, and disruptive versus nondisruptive protest were also investigated. In Study 1, college students who were exposed to an uncertainty salience manipulation and who scored higher on system justification were less likely to protest against the governmental bailout of Wall Street. In Study 2, May Day protesters in Greece who were primed with a system-justifying stereotype exhibited less group-based anger and willingness to protest. In Study 3, members of a British teachers union who were primed with a "system-rejecting" mind-set exhibited decreased system justification and increased willingness to protest. The effect of system justification on nondisruptive protest was mediated by group-based anger. Across very different contexts, measures, and methods, the results reveal that, even among political activists, system justification plays a significant role in undermining willingness to protest.     

The other side of we: when outgroup members express common identity

Previous research on the common ingroup identity model has focused on how one's representations of members of the ingroup and outgroup influence intergroup attitudes. Two studies reported here investigated how learning how others, ingroup or outgroup members, conceive of the groups within a superordinate category affects intergroup bias and willingness to engage in intergroup contact. Across both studies, high school students who learned that other ingroup members categorized students at both schools within the common identity of "students" showed less intergroup bias in evaluations and greater willingness for contact. However, consistent with the hypothesized effects of identity threat, when participants read that outgroup members saw the groups within the superordinate category, they exhibited a relatively negative orientation, except when ingroup members also endorsed a superordinate identity (Study 1). This result occurred even when the relative status of the groups was manipulated (Study 2).     

Advantaged group's emotional reactions to intergroup inequality: the dynamics of pride, guilt, and sympathy

Three studies establish intergroup inequality to investigate how it is emotionally experienced by the advantaged. Studies 1 and 2 examine psychology students' emotional experience of their unequal job situation with worse-off pedagogy students. When inequality is ingroup focused and legitimate, participants experience more pride. However, when inequality is ingroup focused and illegitimate, participants experience more guilt. Sympathy is increased when inequality is outgroup focused and illegitimate. These emotions have particular effects on behavioral tendencies. In Study 2 group-based pride predicts greater ingroup favoritism in a resource distribution task, whereas group-based sympathy predicts less ingroup favoritism. Study 3 replicates these findings in the context of students' willingness to let young immigrants take part in a university sport. Pride predicts less willingness to let immigrants take part whereas sympathy predicts greater willingness. Guilt is a weak predictor of behavioral tendencies in all studies. This shows the specificity of emotions experienced about intergroup inequality.     

Group status, perceptions of threat, and support for social inequality

Members of high-status groups have been shown to favor social inequality, but little research has investigated the boundary conditions of this phenomenon. In the present article we suggest that perceived intergroup threat moderates the relationship between group status and support for social inequality (i.e., social dominance orientation), especially among highly identified group members. In Study 1, Democrats and Republicans rated their party’s relative status and were later exposed to a leading US. Presidential candidate from the opposing party (high threat) or their own party (low threat). In Study 2, university students were made to believe that their school had high or low status and were then presented with threatening or non-threatening information about a rival institution. The results of both studies supported the prediction that status only increases preferences for group-based inequality under conditions of high threat and high ingroup identification.     

Striving for difference: On the spontaneous preference for ingroup members who maximize ingroup positive distinctiveness

Previous research demonstrated that individuals spontaneously prefer ingroup members who display ingroup favoritism rather than egalitarian behaviors (Castelli, Tomelleri, & Zogmaister, 2008). In the current work, we explored what specific strategies toward ingroup favoritism are spontaneously preferred. Results from four studies showed that ingroup members who made it possible for the ingroup to achieve a positive intergroup differentiation were preferred as compared to ingroup members who maximized the absolute gain for the ingroup. Study 5 further demonstrated that in the search for positive distinctiveness people are sensitive to the ratio between the gains of the ingroup and outgroup. Study 6 ruled out a possible alternative explanation. Overall, the current findings indicate that group members who set the difference from an outgroup elicit the most positive spontaneous responses demonstrating that the search for a positive intergroup distinctiveness automatically affects intragroup perception.

内部竞争环境下内群体偏好的维持:群体认同和心理距离的影响

内群体偏好对群体及个人的生存发展都有重要价值。研究通过三个实验揭示了个体在内部竞争下维持内群体偏好的机制。实验一操纵内部竞争(有,无)和群体认同(高,低),发现内部竞争破坏了内群体偏好,而群体认同无法改变此破坏作用。实验二操纵内部竞争(有,无)和内群体心理距离(远、近),发现内部竞争破坏内群体偏好时,心理距离能够调节二者的关系,近心理距离有益于个体在内部竞争下维持内群体偏好。实验三进一步分析了心理距离维持内群体偏好的作用机制,发现心理距离通过个体知觉到的内部竞争感而影响内群体偏好。据此可认为,在内部竞争中维持内群体偏好需更多地关注成员间的关系(缩短心理距离),而非单纯地强调个体和群体间的联结(群体认同)。     

What children remember about ingroup and outgroup peers: effects of stereotypes on children's processing of information about group members

Three studies are reported about children's memory for stereotypic behaviors attributed to ingroup and outgroup members. According to research and theory in social cognition, cues present in the situation make cultural representations about group members accessible, and once primed, influence all phases of the information processing sequence. In Study 1, Euro Canadian and Native Canadian children (N=98) recalled stereotypic behaviors attributed to ingroup and outgroup members. In Study 2 (N=87), the influence of individual difference variables was explored. In Study 3 (N=32), the memory of Native Canadian children living on a First Nation reserve for behaviors attributed to ingroup and outgroup members was studied. Biases in recall were found in Studies 1 and 2, but in Study 3, outgroup favoritism, typically found among low status group members, was reversed among children attending a heritage school. Among the individual difference measures examined, age and level of cognitive development predicted what was remembered about group members. Older Euro Canadian children recalled more negative behaviors about outgroup members than did younger children, and more cognitively mature children recognized more information about ingroup than outgroup members. Results were discussed in terms of cognitive and situational factors influencing children's processing of group-relevant information and the challenges children in low status groups face in maintaining a sense of cultural identity.     

使用加工分离程序对低地位群体内\外群体偏爱的研究

使用加工分离程序（PDP）,以50名农村籍大学生为被试, 采用2（群体：外群体、内群体）×2（特质词效价：积极、消极）×2（加工：意识加工、无意识加工）混合设计,研究了低地位群体对内群体以及高地位外群体偏爱的内隐特征。在本研究情境中发现：农村大学生在提取城市群体积极特质词比消极特质词时的无意识加工更显著;而提取农村群体的积极和消极特质词时,无意识加工的贡献没有显著差异。说明低地位群体成员对外群体有内隐偏爱,对内群体却不存在内隐偏爱。     

New Zealand = bicultural? Implicit and explicit associations between ethnicity and nationhood in the New Zealand context

Four studies examined explicit and implicit perceptions of ethnicity and nationhood in New Zealand (NZ). NZ Europeans/Pakeha (the majority group) endorsed a bicultural perspective and explicitly rated both their own ingroup and Maori (the indigenous peoples of NZ) as contributing equally to NZ national identity and culture (Study 1). Contrary to the divergence between explicit and implicit ethnic-national associations observed in the USA, implicit associations in NZ were generally consistent with explicitly stated values. Pakeha and Maori, but not Asian New Zealanders, were both strongly implicitly associated with the national category ‘NZ’ (Studies 1–3), although this general tendency was qualified by weak levels of ingroup favoritism from all three ethnic groups (Study 2). Finally, the small tendency for Pakeha to implicitly associate their ingroup more strongly with NZ was erased by using moderately well-known Pakeha and Maori rugby players as targets (Study 4). These findings contrast with the American = White implicit associations described by Devos and Banaji ( 2005 ), and provide insight into the ways in which socio-cultural realities foster convergence or divergence between explicit and implicit beliefs about equality and the function of ethnicity in nationhood.

When shared group membership signifies shared subjective experience: I-sharing and the minimal group paradigm

Ingroup favoritism is pervasive. It emerges even in the minimal group paradigm, where participants are assigned to novel groups based on seemingly insignificant characteristics. Yet many of the grouping schemes used in minimal group research may imply something significant: namely, that ingroup members will share in-the-moment subjective experience, or I-share. Two studies examine the role of inferred I-sharing in the minimal group paradigm. We found that (1) people inferred that they would I-share with ingroup members more than outgroup members; (2) inferred I-sharing increased ingroup favoritism; and (3) inferred I-sharing accounted for this ingroup favoritism. Moreover, expecting to I-share with the outgroup improved participants’ attitudes toward the outgroup. These results converge with other research suggesting that people favor ingroup members, in part, because they expect to I-share with them.     

Demonstrating knowledge: The effects of group status on outgroup helping

We examined, in two experiments, the notion that members of low status groups, more than members of high status groups, use outgroup helping as a strategic tool to demonstrate their group's knowledge and boost its reputation. In Study 1 (N = 103), we compared outgroup helping in response to requests for help with offering help. As predicted, participants' knowledge was positively related to outgroup helping in response to requests, but only among members of low status groups. Knowledge also predicted the offering of help among members of high status groups. The second study (N = 75) replicated the findings from the requested help condition and showed that the effect disappeared in a condition in which help could not reflect ingroup knowledge. Additional data support a conclusion in terms of a collective strategy to boost the ingroup's reputation by demonstrating ingroup knowledge to the outgroup. The implications for promoting outgroup helping in a salient intergroup context are discussed.     

Disdain for anxious individuals as a function of mortality salience

Terror management theory research has shown that reminders of mortality tend to decrease liking for people who threaten one's worldview. In research, these worldview threats typically come from outgroup members, but they may also come from ingroup members who are negatively characterized. Presumably the negative characteristics of ingroup members threaten to diminish or undermine the worldview by their association with it. In this research we examine anxious individuals as potentially threatening ingroup members. We hypothesized that a brief contemplation of mortality would lead people to decrease their liking for anxious individuals associated with their ingroup. Study 1 showed that a mortality reminder led people to react more negatively to an anxious police liaison from their community, but not to a calm police liaison. Study 2 showed that a mortality reminder led people who strongly identified with university students to react more negatively to a fellow university student who was anxious, but not to a student who did not display anxiety.

Hiring you makes me look bad: Social-identity based reversals of the ingroup favoritism effect

The current research attempts to explain reversals of ingroup favoritism in terms of one of the prevalent mechanisms generally used to account for positive ingroup bias: Tajfel’s social identity theory. We propose that individuals strategically evaluate ingroup targets in order to maximize their own self-esteem and to avoid costly errors. This strategic evaluation typically results in ingroup favoritism toward an ingroup target member. However, if a positive evaluation of the target poses a significant self-esteem threat, denigration of the target will result. Two studies examined how ingroup and outgroup targets were evaluated when applicants were qualified versus unqualified (Study 1), or when the ingroup target might confirm a negative ingroup stereotype (Study 2). Study 1 results indicated that participants showed ingroup favoritism only toward qualified applicants. Study 2 demonstrated that, when a marginally qualified ingroup applicant has the potential to confirm a negative stereotype, bias against the ingroup is observed. Results of both studies both confirm and provide explanations for ingroup denigration.

Individual-collective primacy and ingroup favoritism: enhancement and protection effects

Individual-collective primacy refers to the extent to which people emphasize their individual interests (individual-primacy) vs. the interests of their ingroup (collective-primacy). This study examined the interactive effects of individual-collective primacy, ingroup performance, and outgroup performance on ingroup favoritism. Participants from two cultures completed a measure of their individual vs. collective-primacy orientation. Performance feedback (favorable or unfavorable) for themselves, their ingroup, and the outgroup were manipulated orthogonally. As predicted, greater collective-primacy led to more ingroup favoritism when the ingroup performed better or worse than the outgroup. However, when the ingroup and outgroup both performed well or both performed poorly, the relationship between collective-primacy and ingroup favoritism was not significant. Implications for analyses of ingroup favoritism and cross-cultural differences are discussed.     

Group evaluations as self-group distancing: Ingroup typicality moderates evaluative intergroup bias in stigmatized groups

Outgroup favoritism among members of stigmatized groups can be seen as a form of self-group distancing. We examined how intergroup evaluations in stigmatized groups vary as a function of ingroup typicality. In Studies 1 and 2, Black participants (N = 125,915; N = 766) more strongly preferred light-skinned or White relative to dark-skinned or Black individuals the lighter their own skin tone. In Study 3, overweight participants (N = 147,540) more strongly preferred normal-weight relative to overweight individuals the lower their own body weight. In Study 4, participants with disabilities (N = 35,058) more strongly preferred non-disabled relative to disabled individuals the less visible they judged their own disability. Relationships between ingroup typicality and intergroup evaluations were at least partially mediated by ingroup identification (Studies 2 and 3). A meta-analysis across studies yielded an average effect size of r = .12. Furthermore, higher ingroup typicality was related to both ingroup and outgroup evaluations. We discuss ingroup typicality as an individual constraint to self-group distancing among stigmatized group members and its relation to intergroup evaluations.
