One of the main attempts at solutions to the lack of women on Wikipedia is to encourage more women to come to Wikipedia and edit. The idea is that greater numbers of women on Wikipedia will result in greater equality on the platform; that there will be more information about women and women's issues, and a hoped for "civilizing influence" on the brutish culture.
This argument is so obviously specious that it is hard for me to imagine that it is being put forth by educated and intelligent people. Women are not a minority - we are around 52% of the world's population and, with a few pockets of exception, we are culturally, politically, sexually, and financially oppressed throughout the planet. If numbers created more equality, where is that equality for women?
The "woman problem" is not numerical and it cannot solved with numbers. The problem is cultural; we know this because attacks against women can be traced to culture, not numbers: the brutal rapes in India, the harassment of German women by recent-arrived immigrant men at the Hamburg railway station on New Year's eve, the racist and sexist attacks on Leslie Jones on Twitter -- none of these can be explained by numbers. In fact, the stats show that over 60% of Twitter users are female, and yet Jones was horribly attacked. Gamergate arose at a time when the number of women in gaming is quite high, with data varying from 40% to over 50% of gamers being women. Women gamers are attacked not because there are too few of them, and there does not appear to be any safety in numbers.
The numbers argument is not only provably false, it is dangerous if mis-applied. Would women be safer walking home alone at night if we encouraged more women to do it? Would having more women at frat parties reduce the rape culture on campus? Would women on Wikipedia be safer if there were more of them? (The statistics from 2011 showed that 13% of editors were female. The Wikimedia Foundation had a goal to increase the number to 25% by 2015, but Jimmy Wales actually stated in 2015 that the number of women was closer to 10% than 25%.) I think that gamergate and Twitter show us that the numbers are not the issue.
In fact, Wikipedia's efforts may have exacerbated the problem. The very public efforts to bring more women editors into Wikipedia (there have been and are organized campaigns both for women and about women) and the addition of more articles by and about women is going to be threatening to some members of the Wikipedia culture. In a recent example, an edit-a-thon produced twelve new articles about women artists. They were immediately marked for deletion, and yet, after analysis, ten of the articles were determined to be suitable, and only two were lost. It is quite likely that twelve new articles about male scientists (Wikipedia greatly values science over art, another bias) would not have produced this reaction; in fact, they might have sailed into the encyclopedia space without a hitch. Some editors are rebelling against the addition of information about women on Wikipedia, seeing it as a kind of reverse sexism (something that came up frequently in the attack on me).
Wikipedia's culture is a "self-run" society. So was the society in the Lord of the Flies. If you are one of the people who believe that we don't need government, that individuals should just battle it out and see who wins, then Wikipedia might be for you. If, instead, you believe that we have a social obligation to provide a safe environment for people, then this self-run society is not going to be appealing. I've felt what it's like to be "Piggy" and I can tell you that it's not something I would want anyone else to go through.
I'm not saying that we do not want more women editing Wikipedia. I am saying that more women does not equate to more safety for women. The safety problem is a cultural problem, not a numbers problem. One of the big challenges is how we can define safety in an actionable way. Title IX, the US statute mandating equality of the sexes in education, revolutionized education and education-related sports. Importantly, it comes under the civil rights area of the Department of Justice. We need a Title IX for the Internet; one that requires those providing public services to make sure that there is no discrimination based on sex. Before we can have such a solution, we need to determine how to define "non-discrimination" in that context. It's not going to be easy, but it is a pre-requisite to solving the problem.
