Wikipedia is like little else in history. Relied on by students, scholars, journalists, and citizens, it’s one of the top 10 websites in the world and the not-so-hidden base of much of our informational infrastructure.

It’s also the product of ridiculous inequality. To wit: It’s estimated that 90 percent of the encyclopedia’s top editors are male.

We’ve known gender has been a problem for Wikipedia for a while. (Diversity generally causes problems for the encyclopedia, as well: Non-Western male editors seem to be rare, too.) The gender gap has been why organizations like Brown University have organized edit-a-thons to add entries on women in science.

But a new story in the MIT Technology Review, by Tom Simonite, reveals how deeply concerned the organization charged with overseeing the encyclopedia is with the lack of new, female editors—and how the community that runs Wikipedia doesn’t always have those concerns in mind.

“The biggest issue is editor diversity,” a founder of the site, Jimmy Wales, tells Simonite. A member of the Wikimedia Board of Trustees, he wants the encyclopedia to “grow the number of editors in topics that need work.”

Those topics, it seems, fall into two categories: articles written mostly by women, and articles about the global south. As Simonite reports:

In 2011, researchers from the University of Minnesota and three other schools showed that articles worked on mostly by female editors—which presumably were more likely to be of interest to women—were significantly shorter than those worked on mostly by male editors or by men and women equally. Another 2011 study, from the University of Oxford, found that 84 percent of entries tagged with a location were about Europe or North America. Antarctica had more entries than any nation in Africa or South America.

The site’s problem isn’t just attracting and retaining women—it’s attracting and retaining any type of new user. Earlier this year, four researchers examined 2,100 new editors over the history of the website, grouped them into various categories, and looked to see whether they stuck around after their first set of edits. Specifically, they wanted to know about “good-faith” new users—users who had the right goals but didn’t quite get their first sets of edits right—and “golden” users—users with both the skills and ideals to immediately improve the encyclopedia.
