The Bias of Crowds: How Implicit Bias Bridges Personal and Systemic Prejudice

As public awareness of implicit bias has grown in recent years, studies have raised important new questions about the nature of implicit bias effects. First, implicit biases are widespread and robust on average, yet are unstable across a few weeks. Second, young children display implicit biases indistinguishable from those of adults, which suggests to many that implicit biases are learned early. Yet, if implicit biases are unstable over weeks, how can they be stable for decades? Third, meta-analyses suggest that individual differences in implicit bias are associated weakly, although significantly, with individual differences in behavioral outcomes. Yet, studies of aggregate levels of implicit bias (i.e., countries, states, counties) are strongly associated with aggregate levels of disparities and discrimination. These puzzles are difficult to reconcile with traditional views, which treat implicit bias as an early-learned attitude that drives discrimination among individuals who are high in bias. We propose an alternative view of implicit bias, rooted in concept accessibility. Concept accessibility can, in principle, vary both chronically and situationally. The empirical evidence, however, suggests that most of the systematic variance in implicit bias is situational. Akin to the “wisdom of crowds” effect, implicit bias may emerge as the aggregate effect of individual fluctuations in concept accessibility that are ephemeral and context-dependent. This bias of crowds theory treats implicit bias tests as measures of situations more than persons. We show how the theory can resolve the puzzles posed and generate new insights into how and why implicit bias propagates inequalities.     

Racial discrimination by low-prejudiced whites. Facial movements as implicit measures of attitudes related to behavior

We investigated the relationship of implicit racial prejudice to discriminatory behavior. White university students chose the best of three applicants (two were White and one was Black) for a prestigious teaching fellowship. They then completed the Implicit Association Test (IAT), a measure of implicit racial bias. Three weeks later, participants completed a second implicit measure of racial bias by viewing photos of Whites and Blacks while facial electromyography (EMG) was recorded from sites corresponding to the muscles used in smiling and frowning. Analyses revealed that bias in cheek EMG activity was related to the race of the chosen applicant, whereas bias on the IAT was not. Motivations to control prejudiced reactions were not related to EMG activity or the race of the applicant chosen, but were related to IAT bias. The findings indicate that facial EMG can be used as an implicit measure of prejudice related to discrimination.     

Recognizing faces across continents: The effect of within-race variations on the own-race bias in face recognition

People are better at recognizing faces of their own race than faces of other racial groups. This own-race bias (ORB) in face recognition manifests in some studies as a full crossover interaction between race of observer and race of face, but in others the interaction is accompanied by main effects or other complexities. We hypothesized that this may be due in part to unacknowledged within-race variation and the implicit assumption that the terms white and black describe perceptually homogeneous race categories. We therefore tested white and black South Africans on their recognition of black and white American faces and black and white South African faces. Our results showed the expected interaction, but only for South African faces. This finding supports explanations of the ORB that are premised on intergroup contact and perceptual experience and highlights the danger of assuming homogeneity of appearance within groups.

The influence of social factors and implicit racial bias on a generalized own‐race effect

The current study sought to determine whether the experimentally reported ‘own‐race effect’ is other‐race specific, or whether it is a generalized effect. The perceptual processing of own‐ versus two groups of other‐race faces was therefore explored in White and South Asian individuals. Participants completed a computer‐based discrimination task of White, South Asian and Black face‐morphs. Results showed a generalized own‐race effect for White and South Asian participants discriminating own‐ versus other‐race (White/South Asian and Black) faces, such that individuals demonstrated a perceptual discrimination advantage for own‐ versus other‐race faces in general. These findings were linked to implicit racial bias and other‐race individuating experience, demonstrating that social variables play an important role in the magnitude of the own‐race effect.

The regulation of explicit and implicit race bias: the role of motivations to respond without prejudice

Three studies examined the moderating role of motivations to respond without prejudice (e.g., internal and external) in expressions of explicit and implicit race bias. In all studies, participants reported their explicit attitudes toward Blacks. Implicit measures consisted of a sequential priming task (Study 1) and the Implicit Association Test (Studies 2 and 3). Study 3 used a cognitive busyness manipulation to preclude effects of controlled processing on implicit responses. In each study, explicit race bias was moderated by internal motivation to respond without prejudice, whereas implicit race bias was moderated by the interaction of internal and external motivation to respond without prejudice. Specifically, high internal, low external participants exhibited lower levels of implicit race bias than did all other participants. Implications for the development of effective self-regulation of race bias are discussed.     

The development of implicit attitudes. Evidence of race evaluations from ages 6 and 10 and adulthood

To understand the origin and development of implicit attitudes, we measured race attitudes in White American 6-year-olds, 10-year-olds, and adults by first developing a child-oriented version of the Implicit Association Test (Child IAT). Remarkably, implicit pro-White/anti-Black bias was evident even in the youngest group, with self-reported attitudes revealing bias in the same direction. In 10-year-olds and adults, the same magnitude of implicit race bias was observed, although self-reported race attitudes became substantially less biased in older children and vanished entirely in adults, who self-reported equally favorable attitudes toward Whites and Blacks. These data are the first to show an asymmetry in the development of implicit and explicit race attitudes, with explicit attitudes becoming more egalitarian and implicit attitudes remaining stable and favoring the in-group across development. We offer a tentative suggestion that mean levels of implicit and explicit attitudes diverge around age 10.     

Awareness is awareness is awareness? Decomposing different aspects of awareness and their role in operant learning of pain sensitivity

Regarding awareness as a consistent concept has contributed to the controversy about implicit learning. The present study emphasized the importance of distinguishing aspects of awareness in order to determine whether learning is implicit. By decomposing awareness into awareness of contingencies, of the procedure being a learning task, and of the reinforcing stimuli, it was demonstrated that implicit operant learning modulated pain sensitivity. All of these aspects of awareness were demonstrated to not be necessary for learning. Additionally, discrimination of contingencies was not necessary on different levels of processing as demonstrated by a verbal and a behavioral method. It was demonstrated that explicit cognitive processes about one's own behavior, impaired learning, even though these cognitions were not immediately related to the learning process. The results of this study are of special interest in the context of pain, since implicit operant learning can explain the gradual development of hypersensitivity in chronic pain.     

Internal motivation to respond without prejudice and automatic egalitarian goal activation

Past research has shown that people who are motivated primarily by their internalized beliefs to respond without prejudice are less likely to show implicit forms of racial bias (e.g., Devine, P. G., Plant, E. A., Amodio, D. M., Harmon-Jones, E., & Vance, S. L. (2002). The regulation of explicit and implicit race bias: The role of motivations to respond without prejudice. Journal of Personality and Social Psychology, 82, 835-848). We tested the idea that such individuals inhibit implicit race bias by automatically activating egalitarian goals. Study 1 showed that participants high in internal motivation but low in external motivation (i.e., primary internal) displayed more egalitarianism, but only after they had been subliminally exposed to African American faces. Study 2 showed that primary internal motivation was associated with lower levels of automatic stereotype activation and this effect was mediated by egalitarian goal activation. These results provide converging evidence that the relationship between primary internal motivation and low levels of implicit bias stems from the activation of egalitarian goals. We discuss the implications of these findings for efforts to reduce cognitive and affective forms of implicit racial bias.     

Individuation training with other‐race faces reduces preschoolers’ implicit racial bias: a link between perceptual and social representation of faces in children

The present study examined whether perceptual individuation training with other‐race faces could reduce preschool children's implicit racial bias. We used an ‘angry = outgroup’ paradigm to measure Chinese children's implicit racial bias against African individuals before and after training. In Experiment 1, children between 4 and 6 years were presented with angry or happy racially ambiguous faces that were morphed between Chinese and African faces. Initially, Chinese children demonstrated implicit racial bias: they categorized happy racially ambiguous faces as own‐race (Chinese) and angry racially ambiguous faces as other‐race (African). Then, the children participated in a training session where they learned to individuate African faces. Children's implicit racial bias was significantly reduced after training relative to that before training. Experiment 2 used the same procedure as Experiment 1, except that Chinese children were trained with own‐race Chinese faces. These children did not display a significant reduction in implicit racial bias. Our results demonstrate that early implicit racial bias can be reduced by presenting children with other‐race face individuation training, and support a linkage between perceptual and social representations of face information in children.     

Intentional control over prejudice: when the choice of the measure matters

We tested the idea that the correlation between implicit and explicit measures of prejudice depends on whether or not groups are normatively protected against discrimination. A pilot study (N=31) showed that 13 categories varied widely in the degree to which it is acceptable to express negative opinions about them. The main study involving 89 Catholic subjects found that explicit (reward allocation, liking ratings) and implicit measures (linguistic intergroup bias) of prejudice were correlated for the outgroup that is not normatively protected against discrimination (Islamic Fundamentalists) but uncorrelated for the outgroup that is protected (Jews).

Family Physicians’ Awareness and Knowledge of the Genetic Information Non-Discrimination Act (GINA)

Historically, physicians have expressed concern about their patients’ risk of genetic discrimination, which has acted as a barrier to uptake of genetic services. The Genetic Information Nondiscrimination Act of 2008 (GINA) is intended to protect patients against employer and health insurance discrimination. Physicians’ awareness and knowledge of GINA has yet to be evaluated. In 2009, we mailed surveys to 1500 randomly selected members of the American Academy of Family Physicians. Questions measured physicians’ current knowledge of GINA and their level of concern for genetic discrimination. In total, 401 physicians completed the survey (response rate 26.9%). Approximately half (54.5%) of physicians had no awareness of GINA. Of physicians who reported basic knowledge of GINA, the majority were aware of the protections offered for group health insurance (92.7%), private health insurance (82.9%), and employment (70.7%). Fewer physicians were aware of GINA’s limitations regarding life insurance (53.7%) and long-term care insurance (58.8%). Physicians demonstrated highest levels of concern for health insurance, life insurance, and long-term care insurance discrimination, with less concern for employer and family/social discrimination. Level of concern for the risk of genetic discrimination did not correlate significantly with awareness of GINA. Approximately 17 months after GINA was signed into federal law, physicians’ knowledge remained limited regarding the existence of this legislation and relevant details. Physicians who are aware of GINA continue to have significant concerns regarding the risk of genetic discrimination. This study reveals the need to further educate physicians about the existence of GINA and the protections offered.     

Seeing others through rose-colored glasses: An affiliation goal and positivity bias in implicit trait impressions

People infer traits from other people's behaviors without intention, awareness, or effort, and this spontaneous trait inference (STI) effect has been shown to be robust. The purpose of the present research was to demonstrate the flexibility of STIs despite the ubiquity. Specifically, we examined the effect of an affiliation goal on STI formation and found a positivity bias. In Experiment 1, perceivers with an affiliation goal formed more positive (versus negative) spontaneous trait inferences compared to those without this goal and those who had been primed with semantically positive, affiliation-unrelated words. Experiment 2 provided evidence that this effect was driven by a motivational state by showing that the positivity bias occurs only when a perceiver's goal to affiliate remains unfulfilled. The goal's interaction with trait valence showed focused, goal-relevant bias. These studies are the first to show that STIs form flexibly in response to perceivers' primed social goals supporting the functionality account of STIs in implicit impression formation.     

Reconnecting to Internal Sensation and Experiences: A Pilot Feasibility Study of an Online Intervention to Improve Interoception and Reduce Suicidal Ideation

Risk factors that are strongly associated with suicide and are amenable to intervention are in need of discovery. This three-study investigation demonstrates that an intervention designed to improve interoception—one potential suicide risk factor—may reduce suicide-related outcomes. Study 1 included 136 undergraduate participants and found that relative to a control condition, participating in a progressive muscle relaxation exercise was associated with reduced implicit identification with suicide through greater body trust, which is one domain of interoception that is consistently linked to suicide-related outcomes. Study 2 included 97 MTurk participants and found that relative to a control condition, participating in a body functionality writing exercise was associated with greater awareness of the body as a whole. Study 3 was a pilot study of a four-session online intervention designed to increase interoception. Study 3 included a sample of 22 clinical participants who completed pre- and postintervention assessments. Participants rated the intervention as highly acceptable and moderately effective. Moreover, the intervention was associated with improvements in interoception and reductions in suicidal ideation, general psychological symptoms, and disordered-eating symptoms. Overall, these findings indicate that our online interoceptive awareness training is acceptable and may be associated with improvements in clinical outcomes. Randomized controlled trials are needed to explore whether the intervention’s purported mechanism—improved interoception—leads to changes in clinical outcomes.     

A neural network model of implicit memory for object recognition

People name well-known objects shown in pictures more quickly if they have studied them previously. The most common interpretation of this priming effect is that processing is facilitated by an implicit memory trace in a perceptual representation system. We show that object priming can be explained instead as a bias in information processing, without recourse to an implicit memory system. Assumptions about psychological decision-making processes and bias were added to a neural network model for object identification, and the model accounted for performance both qualitatively and quantitatively in four object identification experiments.     

Implicit race bias revisited: On the utility of task context in assessing implicit attitude strength

Decades of research have shown that many people harbor implicit attitudes that are positive toward Whites relative to Blacks. With some notable exceptions, these findings are almost always obtained using implicit attitude tasks that assess attitudes toward Whites and Black simultaneously. This makes it difficult to determine whether implicit race bias effects are the result of strong liking for Whites, dislike for Blacks, or both. The present article reports results from a study in which participants' automatic bias towards Blacks and Whites is assessed across multiple evaluative contexts. Results show consistent negative automatic attitudes towards Blacks, but there was considerable variability in participants' attitudes toward Whites. Consistent with the idea that strong attitudes are less contextually sensitive than weaker attitudes (e.g. Krosnick, 1988), it is concluded that participants harbor strong automatic bias against Blacks, but not strong favoritism for Whites. Implications for a context-centered approach to implicit attitude measurement are discussed.     

Understanding Implicit Bias: Putting the Criticism into Perspective

What is the status of research on implicit bias? In light of meta-analyses revealing ostensibly low average correlations between implicit measures and behavior, as well as various other psychometric concerns, criticism has become ubiquitous. We argue that while there are significant challenges and ample room for improvement, research on the causes, psychological properties, and behavioral effects of implicit bias continues to deserve a role in the sciences of the mind as well as in efforts to understand, and ultimately combat, discrimination and inequality.     

Enhanced Cardiac Perception Is Associated With Increased Susceptibility to Framing Effects

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task‐irrelevant emotional stimuli on decision‐making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky‐choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results show a positive association between cardiac awareness and the framing effect, accounting for 24% of the variance in the framing effect. These findings demonstrate that good interoceptive skills are linked to poorer performance in risky choices based on ambivalent information when implicit bias is induced by task‐irrelevant emotional information. These findings support a dual process perspective on decision‐making and suggest that interoceptive skills mediate effects of implicit bias on decisions.     

EFFECTS OF LEARNING ABOUT GENDER DISCRIMINATION ON ADOLESCENT GIRLS' ATTITUDES TOWARD AND INTEREST IN SCIENCE

Gender discrimination has contributed to the gender imbalance in scientific fields. However, research on the effects of informing adolescent girls about gender discrimination in these fields is rare and controversial. To examine the consequences of learning about gender-based occupational discrimination, adolescent girls ( n = 158, ages 11 to 14) were randomly assigned to either (a) a standard intervention program aimed at increasing girls' interest in science or (b) a nearly identical program that included information about gender discrimination. Girls' interest in, and attitudes toward, science were assessed using a pre/post design. Only girls who learned about gender discrimination showed increases in science self-efficacy and belief in the value of science; interest in scientific fields was unaffected by the intervention programs. Theoretical and educational implications are discussed.     

Employment discrimination: the role of implicit attitudes, motivation, and a climate for racial bias

This study is an attempt to replicate and extend research on employment discrimination by A. P. Brief and colleagues (A. P. Brief, J. Dietz, R. R. Cohen, S. D. Pugh, & J. B. Vaslow, 2000). More specifically, the authors attempted (a) to constructively replicate the prior finding that an explicit measure of modern racism would interact with a corporate climate for racial bias to predict discrimination in a hiring context and (b) to extend this finding through the measurement of implicit racist attitudes and motivation to control prejudice. Although the authors were unable to replicate the earlier interaction, they did illustrate that implicit racist attitudes interacted with a climate for racial bias to predict discrimination. Further, results partially illustrate that motivation to control prejudice moderates the relationship between explicit and implicit attitudes. Taken together, the findings illustrate the differences between implicit and explicit racial attitudes in predicting discriminatory behavior.     

Reducing HIV risk-associated sexual behavior among african american adolescents: Testing the generality of intervention effects

This randomized controlled trial tested the effects of a theory-based culture-sensitive HIV risk-reduction intervention among 496 inner-city African American adolescents (mean age = 13 years) and examined the generality of its effects as a function of the facilitator's race and gender and the gender composition of the intervention group. Adolescents who received the HIV risk-reduction intervention expressed more favorable behavioral beliefs about condoms, greater self-efficacy, and stronger condom-use intentions postintervention than did those who received a control intervention on other health issues. Six-month follow-up data collected on 93% of the adolescents revealed that those who received the HIV risk-reduction intervention reported less HIV risk-associated sexual behavior, including unprotected coitus, than did their counterparts in the control condition. Self-reported sexual behavior and changes in self-reported behavior were unrelated to scores on a standard measure of social desirability response bias. There was strong evidence for the generality of intervention effects. Moderator analyses testing eight specific interaction hypotheses and correlational analyses indicated that the effects of the HIV risk-reduction intervention did not vary as a function of the facilitator's race or gender, participant's gender, or the gender composition of the intervention group.
