From a google I find these definitions:
- relating to or of the nature of dramatic or artistic performance.
- "films which push past the limits of current performative trends"
- characterized by the performance of a social or cultural role
- "many feminist theorists have come to stress the contextual and performative aspects of gender"
- relating to or denoting an utterance by means of which the speaker performs a particular act
- "I bet, I apologize, I promise"
Also, possibly more relevantly, there is:
Performative activism is activism done to increase one's social capital rather than because of one's devotion to a cause.
If we look at how this is used in the news:
The week that summed up the performative and inept nature of Brexit
The performative aspects took the shape of a breathless press release from the Home Office on Wednesday announcing: “Detentions under way as government prepares for first flight in nine to eleven weeks”.
Suella Braverman’s small boats crackdown is performative cruelty at its worst
The public want action to reduce dangerous Channel crossings. It also wants Britain to demonstrate competence, compassion and fairness in its response. Instead, the government has chosen a draconian form of performative cruelty that will lead only to yet more chaos, cost and human misery.
Biden’s Israel trip displays ‘performative’ approach to Gaza war
As the war in Gaza nears the end of its second week, analysts say United States President Joe Biden is increasingly acting like a wartime leader, offering a “performative” show of strength and support for Israel.
Performative airstrikes against the Houthis will achieve nothing
After more than a decade of performative sanctions, the public is slowly cottoning onto the fact that they don’t seem to offer much. Amidst this scrutiny, policymakers are increasingly drawn to what might be called the performative airstrike.
It is not at all clear what sense performative is being used here. The Performative activism definition is closest, but I do not think anyone is criticising the devotion to the cause, or that anyone is after "social capital" rather than simply votes. It kind of reads like a synonym of "ineffective" would fit most of them, but not really the Biden story.
When performative is used in the news, what do they mean?
