Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

94.5K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Halo Effect01:27

Halo Effect

229
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...

Stereotype Threat and Self-fulfilling Prophecies

41.8K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

First Impression01:09

First Impression

105
First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

Stereotype Content Model02:16

Stereotype Content Model

15.2K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Motivational Bias01:25

Motivational Bias

246
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...

Area of Science:

  • Social Psychology
  • Intergroup Relations

Background:

  • Significant growth in research evaluating prejudice reduction methods over the past decade.
  • Need for systematic assessment of intervention effectiveness and underlying mechanisms.

Purpose of the Study:

  • To quantitatively and qualitatively assess the effectiveness of various prejudice reduction strategies.
  • To identify which approaches work best, why, and to evaluate the quality of existing research.

Main Methods:

  • Meta-analysis of 418 experiments from 309 manuscripts (2007-2019) for quantitative effect estimation.
  • Qualitative review of landmark studies focusing on intervention duration, measurement, and transparency.

Main Results:

  • Majority of studies (76%) employ "light touch" interventions with uncertain long-term impacts.
  • Mentalizing is a common intervention, but publication bias may inflate reported effects.
  • Landmark studies often report limited effects, indicating a need for theoretical and practical innovation.

Conclusions:

  • Current research efforts are often theoretically and empirically inadequate for generating actionable, evidence-based recommendations.
  • Further innovation in psychological and structural interventions is needed for effective prejudice reduction.
