Out-Group Homogeneity Bias is a cognitive bias that refers to the tendency of individuals to perceive members of out-groups as being more similar to each other than they actually are. This bias can be seen in a variety of contexts, such as race, ethnicity, religion, nationality, and political affiliation. People tend to see members of their own group as being more diverse and unique, while viewing members of other groups as being more similar and interchangeable. One reason for this bias is that people often have limited exposure to members of out-groups, which can lead to overgeneralization and stereotyping. Additionally, people may be more motivated to perceive members of out-groups as being similar in order to justify their negative attitudes or behaviors towards them. For example, a person who holds prejudiced beliefs about a particular group may be more likely to see members of that group as being interchangeable and lacking individuality. Out-Group Homogeneity Bias can have negative consequences, such as perpetuating stereotypes and discrimination. It can also lead to misunderstandings and miscommunications between different groups. However, awareness of this bias can help individuals to recognize and challenge their own assumptions and stereotypes about out-groups.

Out-Group Homogeneity Bias is a way of thinking that assumes people who are different from us all think the same way. This means that we might think that because one person from a different group believes one thing, that everyone in that group believes the same thing. This is not true, as everyone in any group is likely to have different opinions. This type of thinking can lead to us making assumptions about people who are different from us that aren’t true.
