Authors of an ambitious survey of hazing in colleges and universities have turned their attention to high schools and discovered that many freshmen arrive on campus with experience — with 47 percent reporting getting hazed in high school.
As in college, high school hazing pervaded groups from sports teams to the yearbook staff and performing arts, according to professors Elizabeth Allan and Mary Madden of the University of Maine’s College of Education and Human Development.
The hazing included activities from silly stunts to drinking games, with 8 percent of the students drinking to the point of getting sick or passing out, they said.
Just like college students, high schoolers are susceptible to getting swept up in group activities and doing things they might not otherwise do, the authors said.
“That group dynamic can lead to the escalation where you have the hazing that’s been reported in the news, some horrendous incidents,” Madden said.
Among them: a “powder puff” event in which several seniors at a suburban Chicago high school were suspended or charged with roughing up junior girls, and junior varsity football players being sodomized by teammates at their New York high school.
