If you show someone a map and say ‘this is how people get from Point A to Point B,’ the statement is performative when it creates the behavior it describes. In this case, a path gets worn in the ground between Point A and Point B.So, gender performativity:
Thus, performative statements don’t reflect reality (as in the declarative statement ‘this is a pen’), but intervene in it. Performative language is an engine, not a camera.
A model becomes performative when its use increases its predictive capabilities.
—David Stark, Paris, 17.07.2009 Quoted by Brooke Harrington
...I will draw from theatrical, anthropological, and philosophical discourses, but mainly phenomenology, to show that what is called gender identity is a performative accomplishment compelled by social sanction and taboo. [...]
Gender reality is performative which means, quite simply, that it is real only to the extent that it is performed.
Judith Butler, “Performative Acts and Gender Constitution: An Essay in Phenomenology and Feminist Theory” (1988)
