What if the whole dispute over Lawrence Summers’s remarks rests on a mistaken premise? Both Summers and his critics assume that if the differences between men and women are strictly cultural, we can somehow sweep them away. In my new piece for City Journal, “Can We Make Boys and Girls Alike?” I challenge that assumption. I argue that even if the differences between men and women are “merely” cultural, they are effectively ineradicable. To make this point, I look at a body of evidence Lawrence Summers invoked, but that every party to the dispute up to now has ignored–the Israeli Kibbutz movement’s failed utopian experiment in androgyny. There have been calls for male pundits to say more about why there are so few women opinion journalists. Consider this my contribution to the debate.
