Performativity in Social Identity
Quick fact
Judith Butler, in her 1990 book Gender Trouble, argued that gender is not a fixed essence but a 'stylized repetition of acts' that produce the very identity they appear to express. This radical claim became one of the most influential ideas in modern social theory.
Why this is interesting
We usually think of ourselves as having an inner identity that we then express outwardly—our gender, for instance, seems like a natural fact. But what if performing that identity actually creates it, rather than reflects it? This idea, called performativity, flips our understanding of social identity upside down.
