Tajfel’s social identity tradition is about group membership; names are one badge that can trigger that membership in strangers.
Psycholinguistics adds how a name is stored in memory. Neither field treats a name as a soul serial number.
Findings
- Tajfel & Turner — Groups need labels
Social identity theory: people derive esteem from group categories — names can flag those categories instantly.
- Lieberson — Names as taste identity
Choosing a fashionable or antique name is a class and cohort signal, not a private essence.
- Bertrand & Mullainathan — Assigned identity
Employers assigned racialised identity from names and changed callbacks.
- Fryer & Levitt — Names as group markers
Rising distinctiveness of some U.S. Black given names changed the signal’s information content.
- Pilcher — Names and gender identity
Sociological work on how first names do gender in everyday interaction.
- Vandiver / onomastic reviews — Multiple name selves
Surveys of immigrants and trans people document stacked names as ordinary identity technology.
Mechanisms
- Category activation — A name can fire a group schema before conversation starts.
- Self-verification — People prefer others to use the name that matches the self they are trying to be.
- File anchoring — Legal strings persist in credit and criminal databases even after social identity moves.
- Code-switching names — Bilingual families use different names as different identity keys for different rooms.
Debates
- Must legal and lived names match? — Security arguments collide with dignity arguments; many institutions now store both.
- Is renaming inauthentic? — Authenticity talk often ignores that most hereditary surnames were once new.
- Do generation characters fix identity? — They fix a kin position. They do not fix personality or luck.
The science is about recognition and categorisation. Keep “true name magic” in folklore, where it belongs.
