Men explain things to me, and to other women, whether or not they know what they’re talking about. Some men. Every woman knows what I mean. It’s the presumption that makes it hard, at times, for any woman in any field; that keeps women from speaking up and from being heard when they dare; that crushes young women into silence by indicating, the way harassment on the street does, that this is not their world. It trains us in self-doubt and self-limitation just as it exercises men’s unsupported overconfidence.
