The active group shifts with the comparison
Self-Categorization Theory explains how comparison, accessibility, and fit determine which group identity organizes self-perception and influence in a given moment
Premise
The psychologically relevant group in a meeting is not always the one printed on the organization chart. Self-Categorization Theory (SCT) explains how self-perception can shift among levels: individual expert, function member, executive, company employee, or member of a wider profession. The active category changes with the field of comparison.
A leader can therefore address a formally correct audience that does not exist psychologically in that moment. Functional identities may fade when headquarters and country units become the meaningful comparison. The model turns audience identity from a static demographic input into a context-sensitive question about which similarities and differences currently organize perception.
