Brief introduction of social identity theory

Social identity theory is the main process of studying social identity. This theory has been developed since it was first put forward by Teffer in the early 1970s. It represents the separation of European social psychology and North American individualistic social psychology. This theory is a typical intergroup theory.

Social identity theory combines the perspectives of psychology and sociology, focusing on both the control of individual psychological variables and the classification model of group process. This theory originated in the 1970s, and it has increasingly shown its important position through Teffer's "social identity theory" and the subsequent development of self-classification theory, best salience theory and group motivation theory.

Social identity theory emphasizes that individuals identify with their own groups through social classification, thus promoting preference within groups and hostility outside groups. Individuals identify the environment through social classification, identify and classify themselves at the same time, and then establish corresponding social identity through social-classification, social comparison and positive differentiation.

For more than 40 years, social identity theory has been regarded as the most typical theory to explain intragroup conflict. Then, how does the social identity theory explain and promote the internal group phenomenon? Social identity theory is the most influential theory in group identity and inter-group behavior, which holds that individuals identify with their own groups through social classification, resulting in internal group preference and external group discrimination. As Brown pointed out, the contribution of social identity comes from its four concerns. In other words, we should pay attention to inner-group prejudice, reaction to status inequality, homogeneity and stereotype within groups, and change attitudes between groups through contact.

Dynamic is due to its process. Social identity structure is a dynamic social result based on the interaction and influence of memory, consciousness, biological organic characteristics, social structure and social situation. Social identity is rooted in certain psychological processes, such as thinking, behavior and emotion.

Complexity is based on the representation of individual subjectivity in multiple group identities in interpersonal communication.
