The bottom line is, we are all biased. We all tend to think of women’s work as somewhat smaller, derivative, inferior. We do so unconsciously and involuntarily. We are not aware of it, nor do we notice it in others. That’s what all these studies are saying. It’s as if everyone is wearing glasses with the same tint. You’re wearing them even if you’re “open-minded” or “against discrimination”, even if you start your sentences with “I’m not against women, but…”
It is not, and never has been, only about a few individuals who forgot to catch up with the times. It’s not about trolls who say horrible things about women on unmoderated blogs. It’s about you, and me, and everyone we know. It’s about the nice, polite, progressive people who just wish that their female colleague down the hall didn’t try to be more ambitious than is good for her. (She’s clearly good, but does she really think she’s equal to X and Y? And she doesn’t have the same leadership quality, either.) It’s about that paper by two female authors that’s just not quite as groundbreaking as this other paper written by two men. In other words, you need to start by examining your own bias.
Fantastic article, not just about sexism in maths and science, but structural sexism everywhere.
