Social classification often leads to the emphasis on the similarities of people in the same group and the differences between people in different groups. A person can belong to various social categories, but depending on the social environment, different categories are more or less important. For example, a person can define himself as a business executive, an animal lover, and a loyal aunt, but these identities only appear when they are related to social situations. The second process, social identity, is the process of identifying members of a group. Social identification with a group can lead individuals to show how they think members of the group should behave. For example, if a person defines himself as an environmentalist, she may try to save water, recycle as much as possible, and march in a climate-conscious gathering. Through this process, people are emotionally involved in their group members. Therefore, their self-esteem is influenced by their group status.
