What the thing is
Consumer identity is a consumption pattern used for self-description.
Where it came from
It emerged from Social Identity Theory (Tajfel and Turner, 1979), then entered public relations practice via Edward Bernays in the 20th century.
What it gets right
It correctly identifies consumption as active identity work—not passive display. Brands do serve as signifiers. People do align purchases with self-image. Group membership does feed self-esteem.
What it gets wrong
It treats commercial branding as the primary site of identity formation—not family, language, labour, or law. It presumes congruence between brand and self-image is conscious and stable, ignoring coercion, scarcity, and mimicry.
Why it matters now
Because algorithmic targeting now scales Bernays’ tactics: not just selling cigarettes to feminists, but selling identities—‘eco-conscious’, ‘disruptive’, ‘authentic’—as ready-made packages.
Is it worth your time
Yes—if you want to understand how brands weaponise self-image. It is not a theory of taste. It is a theory of leverage.
