Prejudice is a term with many connotations. The most common definition of prejudice in the social sciences is an attitude toward members of a given social group that rests on the fact that they are members of that group (e.g., members of a particular race, ethnicity, religion, or gender; individuals of a particular age, economic class, sexual orientation, or disability status). Generally, most researchers consider prejudice to be the emotional component of reactions toward others based on their social category membership. It is also associated with stereotypes—specific ideas about the members of the group—and with discrimination—behavior toward the members of that group. Discrimination can be either overt (e.g., refusing housing or seating on a bus based on race) or subtle (e.g., administering job qualification tests that favor some ethnic groups based on criteria that are not job related). The notion of groups is central to the concept of prejudice; although prejudice can be felt for specific individuals, it is specifically based on their group membership.
The finding that prejudice often leads to discriminatory behaviors makes the study of prejudice a major focus in the social sciences. Indeed, classic research demonstrates that prejudice and behavior are related, although not always reciprocally. Contemporary researchers therefore seek to understand when prejudice influences behavior and when the situation or the personal characteristics of the perceiver override prejudice’s influence.
