In an increasingly interconnected society, we often face a seemingly contradictory psychological phenomenon called the "black sheep effect." This effect reveals biases in how people evaluate members of their own group, regardless of whether they share a common background, culture, or other attributes. Through a series of psychological studies, we can understand the causes and effects of this phenomenon.
In English, the term black sheep is used to describe a person who is different from the rest of the group or family members, especially those family members who do not fit in. The term comes from the occasional black sheep born among the common white sheep. The coat color of black sheep was considered commercially undesirable because it could not be dyed, creating a negative social impression.
The black sheep effect means that when group members evaluate their peers, they have a more positive view of lovable internal members (Congruent Members) and a more negative view of deviant internal members (Deviant Members).
In 1988, Marques and colleagues conducted a study in which Belgian students rated a group of members: lovable Belgian students, unlovable Belgian students, lovable North African students, and unlovable Belgian students. Cute North African students. The results showed that likable members of the in-group received the highest ratings, while unlovable in-group members received the lowest ratings.
This extreme evaluation of lovable and unlovable internal members shapes the existence of the black sheep effect.
According to social identity theory, group members want to maintain a positive and unique social identity. Therefore, they tend to rate likable ingroup members more highly, which reinforces the positive image of the ingroup. And when a member deviates from group norms, group members will belittle this member more severely to protect the overall image of the group.
This phenomenon not only affects the evaluation of members within the group, but also extends to the protection of personal identity.
Although the black sheep effect is widely supported in the psychology community, some opposite phenomena have also been found. For example, white people usually evaluate unqualified black individuals more negatively than white people. Research shows that the influencing factors of the black sheep effect include the degree of identification with the internal group and the cohesion of the group. At the same time, situational factors that explain behavioral deviations will also affect the emergence of the black sheep effect.
The concept of the "black sheep" is also reflected in many cultures. For example, similar usage exists in French and German, emphasizing that idiosyncratic behavior in a group is unacceptable. This makes the black sheep effect a global social phenomenon. It not only exists in daily life, but also triggered many psychological experiments and research.
The evaluation of deviant individuals in different cultures can help us better understand the complexity of social identity.
The black sheep effect has always affected our social interactions, reminding people that personal stereotypes or prejudices often obscure objective facts when evaluating their peers. Could reflecting on how we view peers who are different from us promote greater tolerance and understanding?
