Prejudice, Stereotypes, and Bias (8B) - Psych & Soc

SECTION 1

Historical Context & Motivation

The scientific study of prejudice, stereotypes, and bias arose from urgent social questions about intergroup conflict, discrimination, and the psychological underpinnings of systemic inequality. Early psychological inquiry into these phenomena was catalyzed by the devastating consequences of World War II, the Holocaust, and the civil rights movements that followed, prompting researchers to ask why ordinary individuals could harbor or act upon hostile attitudes toward entire groups of people. Over the following decades, the field evolved from viewing prejudice as a pathological trait of deviant individuals to recognizing it as a pervasive feature of normal cognitive and social processing, shaped by categorization mechanisms that all humans share.

1954 • Allport's 'The Nature of Prejudice'

Gordon Allport published his foundational text arguing that prejudice emerges from normal categorization processes and proposed the Contact Hypothesis — that intergroup contact under specific conditions can reduce prejudice.

1971 • Tajfel's Minimal Group Paradigm

Henri Tajfel demonstrated that mere categorization into arbitrary groups was sufficient to produce in-group favoritism and out-group derogation, even without meaningful intergroup competition or prior history.

1995 • Fiske's Stereotype Content Model

Susan Fiske and colleagues proposed that stereotypes are organized along two fundamental dimensions — warmth and competence — producing distinct emotional and behavioral responses toward different social groups.

1998 • Implicit Association Test (IAT)

Greenwald, McGhee, and Schwartz introduced the IAT, a reaction-time paradigm measuring implicit bias — automatic associations between social categories and evaluative attributes that operate outside conscious awareness.

2006 • Neuroscience of Prejudice

Neuroimaging studies by Amodio, Phelps, and others revealed that amygdala activation to out-group faces is modulated by both implicit attitudes and prefrontal regulatory processes, linking social cognition to neural substrates.

This trajectory raises the central question that motivates the MCAT's treatment of this topic: if prejudice and stereotyping reflect normal cognitive operations — processes of categorization, schema application, and affective evaluation — then how can we distinguish between adaptive social cognition and harmful intergroup bias, and what mechanisms drive the behavioral expression of these attitudes as discrimination? Understanding this continuum from cognition to behavior is essential for future physicians, who must navigate clinical encounters where implicit biases can influence diagnostic reasoning, treatment decisions, and patient-provider rapport.

SECTION 2

Core Principles & Definitions

The MCAT draws clear distinctions among three interrelated but conceptually distinct constructs — prejudice, stereotypes, and discrimination — which correspond respectively to the affective, cognitive, and behavioral components of intergroup attitudes. Appreciating these distinctions is critical, as each construct operates through partially independent psychological mechanisms and is amenable to different forms of intervention. Additionally, modern social psychology recognizes that these processes can function at both explicit (conscious, deliberate) and implicit (automatic, unconscious) levels, requiring dual-process models to explain the full scope of intergroup phenomena.

Prejudice (Affect)

A preconceived negative attitude or emotional response directed toward members of a group based solely on their group membership. Prejudice is the feeling component — contempt, fear, disgust, or resentment — and can be explicit (endorsed overtly) or implicit (measured through indirect paradigms like the IAT).

Stereotypes (Cognition)

Generalized cognitive schemas or beliefs about the attributes, behaviors, or characteristics of members of a particular group. Stereotypes function as heuristics that simplify social information processing but can lead to biased perception, judgment, and expectation — even when the stereotyper does not endorse prejudicial attitudes.

Discrimination (Behavior)

The behavioral manifestation of prejudice or stereotyping: unjustified differential treatment of individuals based on group membership. Discrimination can be individual (personal acts) or institutional (embedded in policies, laws, or organizational structures), and it may occur without conscious prejudicial intent.

Implicit vs. Explicit Processing

Dual-process models distinguish between automatic (System 1) and controlled (System 2) contributions to bias. Individuals may consciously reject prejudice yet show implicit biases in reaction-time tasks, suggesting that automatic associations formed through cultural exposure can persist independently of endorsed beliefs.

In-Group / Out-Group Dynamics

Social categorization produces in-group favoritism and out-group homogeneity effects. People tend to view members of their own group as diverse and nuanced while perceiving out-group members as more similar to one another — the out-group homogeneity effect — which facilitates stereotyping and dehumanization.

✦

KEY TAKEAWAY

Think of prejudice, stereotypes, and discrimination as three layers of an operating system running in the background. Stereotypes are the stored data files — cognitive representations of social groups. Prejudice is the emotional subroutine triggered when those files are accessed — the affective evaluation attached to the category. Discrimination is the output — the behavioral action executed by the system. Just as a computer can have a stored virus (stereotype) that triggers a malicious process (prejudice) and produces corrupted output (discrimination), each layer can be targeted independently: you can update the data, interrupt the process, or filter the output. For clinicians, awareness of all three layers is essential to delivering equitable care.

SECTION 3

The Tricomponent Model of Intergroup Bias

The following diagram illustrates the tricomponent model of intergroup bias — mapping the cognitive (stereotypes), affective (prejudice), and behavioral (discrimination) components and showing how each can operate through explicit or implicit pathways. The diagram also highlights key moderating variables that strengthen or weaken the translation from cognition and affect to behavior.

The tricomponent model shows how stereotypes (cognitive), prejudice (affective), and discrimination (behavioral) interrelate while remaining partially dissociable. Both explicit and implicit pathways feed into each component, and moderating variables determine when bias translates into discriminatory action.

The key insight conveyed by this model is that the three components, while often correlated, are dissociable. An individual may endorse a stereotype (e.g., 'Group X is aggressive') without harboring negative affect (no prejudice) and without engaging in discriminatory behavior. Conversely, institutional discrimination can persist even when individuals within the institution explicitly reject prejudice. For the MCAT, recognizing this dissociability is essential: questions frequently test whether students can identify which component — cognitive, affective, or behavioral — is operative in a given scenario, and whether it functions at the explicit or implicit level.

SECTION 4

Psychological Mechanisms of Bias Formation

The formation and maintenance of prejudice and stereotypes can be explained through several overlapping theoretical frameworks, each emphasizing different mechanisms. Understanding these mechanisms is crucial because the MCAT tests not only definitional knowledge but also the ability to apply theories to novel scenarios — identifying which mechanism best explains a particular pattern of intergroup behavior.

Social Identity Theory (Tajfel & Turner)

Social Identity Theory (SIT) posits that individuals derive a significant portion of their self-concept from their membership in social groups. The theory identifies three processes: social categorization (classifying people into groups), social identification (adopting the identity of the in-group), and social comparison (evaluating the in-group favorably relative to out-groups). Because self-esteem is partly derived from group membership, individuals are motivated to maintain positive distinctiveness for their in-group, which can fuel prejudice against out-groups as a means of self-enhancement.

Realistic Conflict Theory

Realistic Conflict Theory (RCT), demonstrated in Sherif's classic Robbers Cave experiment (1954), argues that intergroup prejudice arises when groups compete for limited resources. Competition generates hostility, while the introduction of superordinate goals — objectives requiring intergroup cooperation — can reduce it. RCT is particularly useful for understanding prejudice rooted in economic or territorial competition, though it is less effective at explaining prejudice between groups that have no direct resource conflict.

Illusory Correlation & Confirmation Bias

Illusory correlation occurs when individuals perceive a relationship between two variables (e.g., group membership and a negative behavior) that does not exist or is greatly exaggerated, often because both the group and the behavior are statistically distinctive. Once a stereotype is formed, confirmation bias ensures its persistence: information consistent with the stereotype is attended to and remembered, while disconfirming information is discounted or reinterpreted. These cognitive biases create a self-perpetuating cycle where stereotypes become resistant to disconfirmation even when contradictory evidence is encountered.

Self-Fulfilling Prophecy & Stereotype Threat

Stereotypes can become behaviorally confirmed through the mechanism of self-fulfilling prophecy: when a perceiver's expectations about a target person lead the perceiver to behave in ways that elicit expectation-consistent behavior from the target. Relatedly, stereotype threat, first described by Steele and Aronson (1995), occurs when awareness of a negative stereotype about one's group creates performance anxiety that impairs functioning in the stereotyped domain, paradoxically confirming the stereotype at the aggregate level. This is a high-yield MCAT concept: stereotype threat affects performance through working memory depletion, increased arousal, and self-monitoring processes.

Neurobiological Substrates

Functional neuroimaging research has identified the amygdala as a key structure in the rapid, automatic evaluation of out-group faces, with greater activation observed for faces of racial out-group members relative to in-group members in early processing stages. Critically, this activation is modulated by prefrontal cortex (PFC) engagement, particularly the dorsolateral and ventromedial PFC, which exert top-down regulatory control over automatic biases. The anterior cingulate cortex (ACC) has also been implicated in detecting conflicts between egalitarian goals and automatic biased responses, reflecting the neural basis of the explicit-implicit dissociation.

SECTION 5

Classification of Biases & Their Manifestations

Bias manifests in numerous forms that the MCAT expects students to differentiate. The following classification organizes the major types of bias and their characteristic features, providing a framework for recognizing how each operates in social, institutional, and clinical contexts.

The Stereotype Content Model maps social groups into four quadrants defined by perceived warmth and competence. Each quadrant elicits a distinct emotional response: admiration (high warmth/high competence), paternalistic pity (high warmth/low competence), envious prejudice (low warmth/high competence), or contemptuous disgust (low warmth/low competence). The BEHAVIORS, Intergroup Affect and Stereotypes (BIAS) map predicts corresponding behavioral tendencies from active/passive × facilitation/harm.

Type of Bias	Definition	Example
Ethnocentrism	Evaluating other cultures or groups by the standards and norms of one's own culture, typically with the assumption that the in-group's way is superior.	A clinician dismissing a patient's use of traditional healing practices as irrational without understanding the cultural context.
In-group bias	Preferential treatment of in-group members, not necessarily accompanied by hostility toward out-groups. Can operate at implicit levels.	A hiring committee unconsciously favoring candidates who attended their own alma mater.
Out-group homogeneity effect	Perceiving members of out-groups as more similar to one another than members of in-groups ('they all look alike').	A study participant rating faces of other-race individuals as more similar to each other than same-race faces.
Scapegoat theory	Displaced aggression toward a relatively powerless out-group when the true source of frustration is unavailable or too powerful to confront.	Increased hate crimes against immigrant communities during economic recessions.
Just-world hypothesis	The belief that people get what they deserve, leading to victim-blaming attributions that justify existing social inequalities.	Attributing poverty to laziness rather than structural barriers, thus perpetuating discriminatory attitudes.

Key bias types tested on the MCAT with definitions and clinical or social examples.

SECTION 6

Worked Example: Analyzing a Prejudice Scenario

The following worked example demonstrates how to apply the concepts from this lesson to the type of passage-based question commonly encountered on the MCAT. The scenario integrates multiple constructs — stereotype threat, implicit bias, and the tricomponent model — requiring the systematic analysis expected at the graduate-admission level.

MCAT-Style Passage Analysis

1
Step 1 — Read the Scenario

A researcher conducts a study in which female and male participants complete a challenging math test. In the experimental condition, participants are told that the test 'has been shown to produce gender differences in performance.' In the control condition, participants are told that 'the test is gender-fair.' Results show that women in the experimental condition perform significantly worse than women in the control condition, while men's performance does not differ between conditions. Question: Which concept best explains the performance decrement observed in women in the experimental condition?
2
Step 2 — Identify the Key Construct

The scenario describes a classic stereotype threat paradigm. The critical features are: (a) activation of a negative stereotype about an in-group ('women are poor at math'), (b) a domain-relevant task (math test), (c) performance decrement in the stereotyped group under threat conditions only, and (d) no effect on the non-stereotyped group. The mere mention of 'gender differences' activates the relevant stereotype and creates evaluative pressure.

Construct: Stereotype Threat (Steele & Aronson, 1995)
3
Step 3 — Eliminate Alternative Explanations

Could this be simple prejudice? No — prejudice is an attitude held by a perceiver toward a target; here, the performance effect operates within the stereotyped group itself, not between groups evaluating each other. Could it be self-fulfilling prophecy? While related, self-fulfilling prophecy involves a perceiver's behavior toward a target eliciting expectation-consistent behavior. In this scenario, no perceiver-target interaction occurs; the effect is mediated entirely by the individual's own awareness of the stereotype. Could it be confirmation bias? No — confirmation bias refers to selective attention to stereotype-consistent information, not performance impairment.

Self-fulfilling prophecy, prejudice, and confirmation bias are ruled out based on the specific features of the scenario.
4
Step 4 — Explain the Mechanism

Stereotype threat impairs performance through several pathways: (1) working memory depletion — cognitive resources are consumed by anxiety, self-monitoring, and attempts to suppress stereotype-related thoughts; (2) increased physiological arousal — cortisol and sympathetic nervous system activation impair executive functioning; and (3) prevention focus — individuals shift from approach-oriented (trying to succeed) to avoidance-oriented (trying not to fail) processing, which is suboptimal for complex problem-solving.

Answer: Stereotype threat — the awareness of a negative in-group stereotype creates performance anxiety that consumes cognitive resources and impairs task performance.
5
Step 5 — Connect to Broader Concepts

Note that stereotype threat demonstrates how stereotypes (the cognitive component) can produce real-world behavioral consequences even in the absence of a prejudiced perceiver. This is a powerful illustration of the tricomponent model's dissociability principle. Clinically, stereotype threat research has implications for healthcare disparities: patients from stigmatized groups may underperform on cognitive assessments or fail to communicate symptoms effectively when the clinical setting activates relevant stereotypes about their group.

SECTION 7

Prejudice Reduction: Strategies & Limitations

A thorough understanding of prejudice requires not only identifying its causes and manifestations but also evaluating the evidence for various reduction strategies. The MCAT tests knowledge of these interventions and their boundary conditions, expecting students to distinguish between approaches that target cognition, affect, or behavior.

Strategy	Mechanism & Evidence	Limitations
Intergroup Contact (Allport)	Requires equal status, common goals, intergroup cooperation, and institutional support. Meta-analyses show robust effects (r ≈ −0.21) across diverse group categories. Extended and imagined contact variants also show promise.	Conditions often difficult to achieve in naturalistic settings. Effects may not generalize beyond the specific out-group members encountered. Can produce anxiety if poorly structured.
Recategorization (Common In-group Identity)	Gaertner & Dovidio's model: reframing two groups as members of a single superordinate category reduces intergroup bias by transforming 'them' into 'us.' Effective in laboratory and organizational settings.	May threaten subgroup identity. Groups with strong ethnic or cultural identities may resist recategorization, leading to reactance.
Perspective-Taking	Imagining the psychological experience of an out-group member increases empathy and reduces stereotypical judgments. Engages affective component directly.	Can be superficial or lead to inaccurate assumptions if not informed by actual out-group experiences. May increase perceived overlap with the out-group without changing structural conditions.
Stereotype Suppression	Deliberate efforts to suppress stereotypical thoughts. Paradoxically, suppression can produce a rebound effect (Macrae et al., 1994): after suppression, stereotype activation increases relative to baseline.	Rebound effect makes this strategy counterproductive. Requires sustained cognitive effort and is vulnerable to cognitive load.
Individuation	Focusing on individual attributes rather than group membership reduces reliance on categorical thinking. Supported by research on the effects of personal information availability.	Cognitively effortful; under time pressure or cognitive load, people revert to category-based processing. Does not address structural or institutional discrimination.

Major prejudice reduction strategies with their theoretical bases, supporting evidence, and known limitations.

✦

KEY TAKEAWAY

Prejudice reduction is analogous to treating a multi-system disease in medicine: no single intervention addresses all pathways simultaneously. Contact targets the affective component (reducing anxiety and building empathy through exposure), individuation targets the cognitive component (disrupting categorical processing), and institutional policy changes target the behavioral component (constraining discriminatory actions regardless of attitudes). The most effective approaches are multimodal — just as combination therapy outperforms monotherapy in many clinical contexts.

SECTION 8

Connections to Healthcare Disparities & Advanced Theory

The MCAT's inclusion of prejudice, stereotypes, and bias within Foundational Concept 8 reflects the growing recognition that these phenomena directly impact health outcomes and clinical practice. Research consistently demonstrates that implicit biases among healthcare providers predict disparities in treatment recommendations, pain management, referral patterns, and patient-provider communication, making this material not merely theoretical but clinically actionable.

Concept	Basic Social Psychology	Clinical / Healthcare Application
Implicit bias	Automatic associations between social groups and evaluative attributes, measured via IAT and other indirect tasks.	Physicians with higher pro-White implicit bias are less likely to recommend thrombolysis for Black patients presenting with chest pain (Green et al., 2007).
Stereotype threat	Performance impairment due to awareness of negative in-group stereotypes in a relevant domain.	Patients from stigmatized groups may underperform on cognitive screening tools (e.g., MMSE) in clinical settings that activate stereotypes, leading to misdiagnosis.
Institutional discrimination	Systematic policies and practices that disadvantage members of certain groups, regardless of individuals' attitudes.	Formulary restrictions, geographic distribution of healthcare facilities, and insurance structures that disproportionately limit access for minority populations.
Intersectionality	Crenshaw's framework: individuals hold multiple social identities that interact to produce unique experiences of privilege and oppression.	A Black woman's experience of bias in healthcare may differ qualitatively from that of a Black man or a White woman — compound stigma affects diagnosis, communication, and trust.

Connecting core social psychology constructs to their healthcare implications — a key MCAT integration point.

💡

MCAT Integration Note

The Psychological, Social, and Biological Foundations section frequently asks questions that bridge basic social psychology and healthcare contexts. Expect questions that require you to identify which specific bias mechanism (implicit bias, stereotype threat, institutional discrimination, or self-fulfilling prophecy) is operating in a clinical vignette, and to predict how it might affect patient outcomes. The distinction between individual-level versus structural-level explanations for health disparities is particularly high-yield.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

A researcher finds that participants who score low on explicit measures of racial prejudice (self-report scales) still show significant implicit racial bias on the IAT. How does dual-process theory explain this dissociation, and what does it imply about the relationship between explicit attitudes and implicit associations?

Show answer

Dual-process theory distinguishes between explicit attitudes (controlled, deliberate, accessible to introspection) and implicit associations (automatic, fast, formed through repeated cultural exposure). The dissociation occurs because explicit attitudes are processed by System 2 (reflective, effortful) and can be updated by egalitarian values, while implicit associations are processed by System 1 (automatic, habitual) and may reflect culturally absorbed associations that persist independently of consciously endorsed beliefs. This implies that self-report measures alone are insufficient to capture the full spectrum of an individual's intergroup attitudes, and that implicit biases can influence behavior — particularly under conditions of cognitive load, time pressure, or ambiguity — even when explicit prejudice is low.

Question 2: BASIC CALCULATION

In a study of the out-group homogeneity effect, participants rate the variability of personality traits in their in-group versus an out-group on a 1–10 scale. In-group variability ratings average 7.8 (SD = 1.2), while out-group variability ratings average 4.2 (SD = 1.5). Calculate Cohen's d for this difference. What does this effect size indicate about the magnitude of the out-group homogeneity effect in this sample?

Show answer

Cohen's d is calculated as the difference between means divided by the pooled standard deviation. The pooled SD = √[(1.2² + 1.5²)/2] = √[(1.44 + 2.25)/2] = √[1.845] ≈ 1.358. Therefore, d = (7.8 − 4.2)/1.358 ≈ 3.6/1.358 ≈ 2.65. This represents a very large effect size by conventional standards (Cohen's benchmarks: small = 0.2, medium = 0.5, large = 0.8). A d of 2.65 indicates that participants perceive dramatically more homogeneity in the out-group relative to the in-group, consistent with strong out-group homogeneity bias. In real research, effect sizes this large are uncommon and may suggest the rating scale captured the effect with minimal noise.

Question 3: INTERMEDIATE

A passage describes a study where White participants are randomly assigned to either a high-cognitive-load condition (counting backward by 7s while evaluating job applications) or a low-cognitive-load condition. In the low-load condition, participants show no difference in hiring recommendations for Black vs. White applicants with identical qualifications. In the high-load condition, participants recommend Black applicants at significantly lower rates. Which psychological mechanism best explains this interaction, and how does it relate to the MODE model of attitude-behavior relations?

Show answer

The interaction is best explained by the Motivation and Opportunity as Determinants (MODE) model proposed by Fazio. According to this model, the expression of implicit attitudes in behavior depends on both motivation (desire to control bias) and opportunity (availability of cognitive resources). In the low-load condition, participants have the cognitive capacity to override automatic biased associations and apply egalitarian standards, producing equitable recommendations. In the high-load condition, the dual task depletes executive resources needed for bias regulation, allowing implicit racial bias to influence decisions. This demonstrates that implicit biases are not invariably expressed in behavior — they emerge when controlled processing is compromised. The key moderators are cognitive load (reducing opportunity) and internal/external motivation to respond without prejudice. For the MCAT, this scenario illustrates the critical principle that implicit bias operates below the threshold of awareness but becomes behaviorally consequential when self-regulatory resources are taxed.

Question 4: APPLIED

A hospital implements a mandatory implicit bias training program for all clinical staff. Six months later, staff IAT scores show a small but statistically significant reduction in implicit racial bias. However, audit data reveal no change in racial disparities in pain management prescriptions. Using concepts from this lesson, provide at least three explanations for why reduced implicit bias scores did not translate into reduced disparities, and suggest one evidence-based modification to the training program.

Show answer

Several explanations account for this dissociation. First, the IAT measures associations at the individual level, but pain management disparities may be driven by institutional/structural factors (formulary policies, triage algorithms, staffing patterns) that operate independently of individual attitudes — addressing implicit bias alone cannot resolve institutional discrimination. Second, the reduction in IAT scores may reflect demand characteristics or strategic responding on the retest rather than genuine attitude change; the IAT is susceptible to faking, particularly when participants know they are being evaluated. Third, even genuine reductions in implicit associations may be too small to produce detectable changes in complex clinical behaviors, which are multiply determined by time pressure, patient communication style, clinical uncertainty, and systemic protocols. Fourth, the training may have improved awareness without providing concrete behavioral strategies (implementation intentions, checklists, standardized protocols) to interrupt the bias-behavior link in real-time clinical encounters. An evidence-based modification would be to supplement attitudinal training with structural interventions — such as standardized pain assessment tools that require documented justification for prescribing decisions — effectively constraining the opportunity for bias to influence behavior regardless of the clinician's implicit attitudes.

Question 5: CRITICAL THINKING

Critically evaluate the following claim: 'Because all humans possess cognitive categorization mechanisms that produce stereotypes, and because stereotypes can operate implicitly outside of awareness, it follows that all prejudice is inevitable and universal, and that moral responsibility for discriminatory behavior is diminished.' Drawing on the theoretical frameworks covered in this lesson, construct an argument that acknowledges the cognitive basis of stereotyping while preserving a meaningful account of individual and institutional responsibility for bias reduction.

Show answer

The claim conflates three levels that must be distinguished. First, while social categorization is indeed a universal cognitive process (Allport, 1954; Tajfel, 1971), categorization does not deterministically produce prejudice — it is a necessary but not sufficient condition. The content of stereotypes is culturally transmitted, not innate, meaning that what is categorized and how categories are evaluated are products of socialization, media exposure, and institutional structures that are modifiable. Second, the implicit/explicit distinction does not eliminate agency. The MODE model demonstrates that implicit biases are most likely to influence behavior when motivation or opportunity for controlled processing is lacking. Individuals can develop regulatory strategies (implementation intentions, perspective-taking habits, self-monitoring) that reduce the behavioral expression of bias, much as a physician can recognize an automatic diagnostic heuristic as potentially erroneous and engage in deliberate analytic reasoning. The existence of an automatic process does not preclude the exercise of top-down control — indeed, this is precisely the function of the prefrontal cortex. Third, institutional responsibility is entirely independent of individual-level implicit bias: organizations can design structures, protocols, and accountability systems that reduce disparities regardless of whether individual actors harbor implicit biases. The strongest argument thus holds that recognizing the cognitive naturalness of categorization should motivate — not excuse — proactive efforts at multiple levels (individual, interpersonal, institutional, and cultural) to mitigate its harmful consequences.

SUMMARY

Lesson Summary

Summary

This lesson examined the three components of intergroup bias: stereotypes (cognitive schemas about group attributes), prejudice (negative affective responses toward groups), and discrimination (behavioral differential treatment). These constructs are partially dissociable and operate through both explicit (controlled) and implicit (automatic) pathways. Key theoretical frameworks include Social Identity Theory (self-esteem from group membership drives in-group favoritism), Realistic Conflict Theory (competition for resources generates intergroup hostility), and the Stereotype Content Model (warmth × competence dimensions predict distinct emotional and behavioral responses). Stereotype threat demonstrates how awareness of in-group stereotypes impairs performance through working memory depletion and arousal, and the IAT provides an indirect measure of implicit associations that can dissociate from self-reported attitudes.

Prejudice reduction strategies include intergroup contact (under Allport's conditions), recategorization (common in-group identity), perspective-taking, and individuation — each targeting different components of the tricomponent model. Clinically, implicit bias in healthcare contributes to disparities in diagnosis, treatment, and patient-provider communication. The most effective interventions are multimodal, addressing individual attitudes alongside institutional and structural determinants of discrimination. For the MCAT, focus on distinguishing between cognitive, affective, and behavioral components; recognizing explicit vs. implicit processes; identifying specific bias mechanisms in passage-based scenarios; and connecting social psychological theory to healthcare equity.
