In- and Out-Groups

在社交场合中，人们常常会基于某些类别（如性别）或特定兴趣而聚集成群。

这种分类可能引发对同群体成员的偏袒&nbsp;以及情感上的联结，从而将社会世界划分为“我们”与“他们”，即形成内群体——个体认同并归属的特定群体——与外群体——被视为本质不同的群体。

在这种情况下，每个人都在自己的群体内拥有强大的身份认同和自尊来源，而紧密的联系可能会产生内群体偏见——即更偏好自己所属的群体而非其他群体。

由于个体倾向于维持积极的自我认知，为了保护特定内群体的成员，可能会产生偏见和歧视。

因此，内群体可能会将自身遭遇的任何不幸归咎于外群体&nbsp;。这一现象被称为替罪羊机制——即当内群体在实现某一目标过程中遇到任何困扰或所谓威胁时，将责任归罪于外群体的行为。

好消息是，群体之间的社会不稳定可以通过协调得到解决。例如，通过有意识的沟通，内群体可以认识并理解外群体的经历&nbsp;，从而促进积极的改变。

内群与外群

每个人都有其性别、种族、年龄和社会经济群体归属。这些群体为我们提供了重要的身份认同和自尊来源（Tajfel &amp; Turner, 1979），并作为&nbsp;我们的内群体。所谓内群体，是指我们认同或将自己视为其中一员的群体。

我们所不属于的群体被称为外群体，即我们认为在根本上与我们不同的群体。例如，如果你是女性，那么你的性别内群体包括所有女性，而你的性别外群体则包括所有男性。人们通常认为性别群体在性格特征、特点、社会角色和兴趣方面彼此存在根本差异。

由于我们通常对自己所属的群体有强烈的归属感和情感联系，因此会形成内群体偏见：即更偏好自己的群体而非其他群体。这种内群体偏见可能导致偏见和歧视，因为外群体被视为不同，并且不如我们的内群体受欢迎。偏见的一个功能是帮助我们对自己产生良好的感觉，并维持积极的自我认知。这种希望自我感觉良好的需求也延伸到了我们的内群体：我们希望内群体受到肯定并加以保护。我们会在个体层面和内群体层面上努力应对威胁，而这种应对常常表现为将问题归咎于某个外群体。替罪羊机制是指当内群体遭遇挫折或在实现目标过程中受阻时，将责任归咎于外群体的行为（Allport, 1954）。

尽管群体动力学似乎只会促使群体走向冲突，但仍有一些力量能够促进群体之间的和解：表达共情、承认双方过去所遭受的痛苦，以及停止破坏性行为。

in-group bias and scapegoating

In-group bias and scapegoating help explain how people react to groups they belong to and groups they see as different. An in-group is a group a person identifies with or feels part of. An out-group is a group a person does not belong to and sees as fundamentally different.

People often use group membership as part of their identity and self-esteem. Gender, race, age, and social economic group can all serve as in-groups. For example, if a person is female, females are the in-group and males are the out-group. People may see gender groups as different in personality traits, social roles, characteristics, and interests.

Because people feel a strong sense of belonging to their in-groups, they can develop in-group bias. This is a preference for their own group over other groups. In-group bias can lead to prejudice and discrimination because the out-group is seen as different and is less preferred.

Prejudice can also help people maintain a positive self-concept. That need to feel good about oneself can extend to the in-group as well. When people feel threatened, they may try to protect their group. One response is scapegoating, which means blaming an out-group when the in-group is frustrated or blocked from reaching a goal.

Not all group conflict stays the same. Some forces can support reconciliation between groups. These include empathy, recognition of past suffering on both sides, and stopping destructive behavior. In this video, cats and rabbits act as a metaphor for the in-groups and out-groups people choose, such as one sports team and an opposing team.

stereotypes, prejudice, and discrimination

How Bias Shapes Social Group Behavior

Prejudice, stereotypes, and discrimination are ways bias can shape how people think and act toward social groups. Social groups help form identity, and people can belong to many groups at once, including gender, race, ethnicity, nationality, social class, religion, sexual orientation, and profession. Differences can be hard for some people to accept, but education, contact, and relationships with other cultural groups can reduce prejudice. Even imagining a positive interaction with someone from...

stereotype content model

Warmth and Competence in Stereotypes

The Stereotype Content Model explains how people judge social groups using two main ideas: warmth and competence. Warmth means a group’s perceived intent, or whether it seems likely to help or cause harm. Competence means the group’s ability to carry out that intent. Susan Fiske and colleagues first proposed this model, and it helps show why first impressions can shape behavior toward other people. The model places stereotypes into four main categories. A group can be low in warmth and low in...

Robbers Cave and Group Conflict

The Robbers Cave study shows how group conflict can grow when teams are forced to compete. In the 1950s, two boys’ groups at an Oklahoma summer camp, called the Rattlers and the Eagles, entered a week-long tournament. As the competition continued, their hostility grew into name-calling, fistfights, vandalism, and damage to property. The study also showed one way to reduce that tension. Researchers used superordinate goals, which are shared goals that groups can only reach by working together.

stereotype threat and self-fulfilling prophecies

How Stereotypes Shape Behavior

Stereotypes can shape behavior through self-fulfilling prophecy and confirmation bias. A self-fulfilling prophecy happens when an expectation changes how someone acts, and that behavior helps make the expectation come true. When people hold stereotypes about others, they may treat them in ways that match those expectations. That treatment can then push the other person to act in the same way, which seems to confirm the stereotype. A classic study by Rosenthal and Jacobson in 1968 showed this...
