In 2017 Tonja Jacobi and Dylan Schweers of Northwestern University published a study of interruptions at oral arguments of the Supreme Court. They found that male justices interrupted female justices “approximately three times as often as they interrupt each other.”
Over the last 12 years they studied, “32% of interruptions were of the female justices,” but “only 4% were by the female justices.” In the 2015 term, “65.9% of all interruptions on the court were directed at the three female justices.”
