With Lost Boys, James Garbarino became our foremost explicator of violent behavior in boys. Now he turns his attention to its increasing incidence in girls. Twenty-five years ago, ten boys were arrested for assault for every one girl. Now that ratio is four-to-one and dropping. Combining clinical experience with incisive analyses of social trends, Garbarino traces the factors—many of them essentially positive—behind the epidemic: girls’ increased participation in sports and greater comfort with their physicality, but also their lack of training in handling aggression. See Jane Hit goes beyond diagnosing the problem to outline a clear-eyed, compassionate solution.
