What process involves modifying one’s beliefs, attitudes, and behavior to align with those of a group?

The process of modifying one's beliefs, attitudes, and behavior to align with those of a group is known as social identification. This occurs when individuals see themselves as part of a group and start to adopt the group's norms, values, and behaviors as their own. Social identification often leads to a sense of belonging and community, as individuals connect their identity with that of the group, thereby influencing how they think and act.

In contrast, social categorization involves sorting people into groups based on characteristics, which does not inherently change one's behavior or beliefs. Social comparison, on the other hand, focuses on evaluating oneself in relation to others, potentially leading to changes in self-perception but not necessarily aligning one's beliefs with those of a group. The fundamental attribution error refers to the tendency to overemphasize personal characteristics in explaining others' behavior while downplaying situational factors, which is unrelated to the process of aligning one's beliefs or behaviors with a group.
