Summary
Social categorization is biased, with people more likely to assign faces to groups based on stereotypical traits, especially if prejudiced. This bias is stronger when traits align with group stereotypes, influencing how individuals perceive social groups.
Area of Science:
- Social Psychology
- Cognitive Science
- Stereotype Research
Background:
- Social categorization is fundamental to human cognition.
- Prejudice can influence social categorization processes.
- The concept of 'normative fit' suggests that category membership is easier when features align with category expectations.
Purpose of the Study:
- To investigate whether social categorization is biased by stereotype-relevant facial features.
- To examine the role of prejudice in the overallocation of faces to social categories.
- To test the normative fit hypothesis regarding stereotype-relevant traits and category allocation.
Main Methods:
- Participants categorized faces presented with various features (e.g., criminal, stupid, feminine).
- Studies involved stigmatized categories like Moroccan and homosexual groups.
- Individual differences in implicit prejudice were measured and correlated with categorization patterns.
Main Results:
- Faces with stereotype-relevant traits were overallocated to target categories, regardless of trait valence (positive or negative).
- Prejudice levels influenced overallocation: negatively prejudiced individuals showed more overallocation for negative stereotype-relevant traits and less for positive ones.
- Stereotype-irrelevant traits did not consistently lead to overallocation.
Conclusions:
- Social categorization is inherently biased, favoring stereotype-relevant features.
- Normative fit, the alignment between features and category stereotypes, drives this bias.
- Prejudice modulates the impact of stereotype-relevant traits, enhancing fit when evaluatively congruent.

01:31In- and Out-Groups
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.
02:16Stereotype Content Model
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 categorization, a person will feel...
02:55Stereotypes, Prejudice, and Discrimination
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 are...
02:13The Representativeness Heuristic
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.
01:29Self-Serving Bias
Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...
01:14Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
