One of those women, one of the Edit-a-thon’s organizers Jacqueline Mabey, thinks most of the Wikipedia gender gap comes down to socialized gendering. “We don’t raise young women to consider themselves authorities on anything,” she said. “We raise them to doubt, constantly, their work and themselves.” Librarians are widely considered the only female-dominated group that reliably loves Wikipedia — but even they, said Mabey, tend to doubt their qualification to edit it. “These are women with double masters degrees,” she said. “I’m like, yes, you can edit it! The 18-year-old boy who doesn’t know anything is editing it, and he doesn’t even question it!”
