Steubenville. The Naval Academy. Vanderbilt University. The stories of young men sexually assaulting young women seem never to stop, despite all the education we’ve had and all the progress we’ve supposedly made, and there are times when I find myself darkly wondering if there’s some ineradicable predatory streak in the male subset of our species.

Wrong, Chris Kilmartin told me. It’s not DNA we’re up against; it’s movies, manners and a set of mores, magnified in the worlds of the military and sports, that assign different roles and different worth to men and women. Fix that culture and we can keep women a whole lot safer.

I reached out to Kilmartin, a psychology professor and the author of the textbook “The Masculine Self,” after learning that the military is repeatedly reaching out to him. Right now he’s in Colorado, at the Air Force Academy, which imported him for a year to teach in the behavioral sciences department and advise the school on preventing sexual violence.

He previously worked on a Naval Academy curriculum with that aim, and helped to write a training film for the Army. At a time of heightened concern about rape and related crimes in the armed services, he’s being welcomed as someone with insights into the problem.
