What is the tendency to favor our own group called?

The tendency to favor our own group is referred to as ingroup bias. This phenomenon occurs when individuals exhibit preferential treatment or positive feelings towards members of their own social group, while often harboring negative feelings or biases against those outside of their group (the outgroup). Ingroup bias is rooted in social identity theory, which suggests that individuals derive part of their self-esteem from the groups to which they belong. This leads to a natural inclination to view one's own group as superior and to support it more than others.

Ingroup bias can manifest in various formats, such as favoring members in decision-making processes, exhibiting loyalty to group interests, and perceiving members of one's own group as more relatable and trustworthy. The practice can reinforce group cohesion and solidarity but may also contribute to prejudice and discrimination against outgroup members. Understanding ingroup bias is crucial in social psychology, as it highlights how group dynamics can shape interpersonal relationships and societal structures.
