Summary
Biological essentialism beliefs correlate with social biases like stereotyping and prejudice. However, experimental evidence did not support biological essentialism causing these biases in a large-scale study.
Area of Science:
- Social Psychology
- Belief Systems
- Group Dynamics
Background:
- Biological essentialism, the belief that groups have inherent, fixed natures, is linked to social biases.
- Prior research suggested a causal link where biological essentialism promotes bias, including group emphasis, stereotypes, and prejudice.
- Existing experimental studies supported this causal direction, prompting further investigation.
Purpose of the Study:
- To experimentally investigate whether biological essentialism causally leads to increased social bias.
- To extend previous findings by examining "value-based" essentialism.
- To re-examine the correlational relationship between essentialism and various forms of bias.
Main Methods:
- A large-scale study (N=1,903) involving experimental manipulation to influence biological essentialist beliefs.
- Correlational analyses examining the relationship between essentialist beliefs and measures of group emphasis, stereotyping, and prejudice.
- Comparison of bias levels between an experimental condition and a control condition.
Main Results:
- The manipulation successfully altered essentialist beliefs.
- Essentialist beliefs showed significant correlations with group emphasis (Study 1), stereotyping (Studies 2, 3a-3c), and prejudice (Study 3a).
- No experimental evidence was found to support biological essentialism causally leading to increased bias.
Conclusions:
- While essentialist beliefs are strongly correlated with social biases, the experimental findings do not support a causal link from biological essentialism to these biases.
- The study highlights the complex relationship between essentialism and bias, suggesting that correlation does not imply causation in this context.
- Further research is needed to understand the nuanced interplay between essentialist beliefs and the endorsement of social biases.

In- 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.

Fundamental 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...

Stereotypes, 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...

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Evolutionary Psychology
331
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Introduction to Biological Bases of Psychology

Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
