Syllabus: How Do Groups Shape Identity and Collective Action?
Trace how the comparison being made changes who counts as ‘us.’
Why you’re reading it. Introduce identity as something to explain, not a fixed property of every category.
A question to consider. How might two rival student clubs become one group when negotiating access to a shared building?
Why this reading
The same person can understand a situation as an individual, a team member, or part of a wider community. Self-categorization theory explains how the comparison being made can change which identity matters.
Before you read
Personal and social identity are levels of self-definition. Salience means becoming relevant in a situation. Depersonalization here means seeing oneself through a group identity; it is neither a clinical diagnosis nor a loss of thought or agency.
Read for
- Separate a category's accessibility from its fit with the situation.
- Compare perceived differences within and between groups, and the expectations that make those differences meaningful.
- Distinguish changes in identity's salience from changes in its content.
Consider afterwards
- Two departments become one team during a dispute with another organization. What changed in the frame of comparison, and what evidence would challenge that explanation?
Editorial context
This theoretical account uses selected studies to develop its argument. It does not demonstrate that every category becomes meaningful or that identification inevitably causes hostility. The authors allow competing identities and emphasize the interaction of context, expectations, and readiness. Explanatory flexibility also makes precise, discriminating predictions important.
