Wikipedia: It's not for girls

Time-rich computer scientists in America say they have conclusive proof that online encyclopedia/graffiti archive Wikipedia is biased against women. Hardly any of the site's legions of volunteer editors are female, and the few who are get picked on by the male majority: as a result Wikipedia fails to provide quality in-depth …

[Anonymous Coward]

As well as a few guys pretending to be female...

A lot of women on the internet either pretend to be male or don't mention their gender at all.

[Anonymous Coward]

"Sex", please; ...

... not gender. Being male or female is >not< gender: it's sex - got that ?

Gender is a concept in grammar that describes (among other things) which articles and adjectival endings "agree" with the noun.

So, for instance, the German for "the little girl" is das Madchen *. The noun has neuter gender, even though the girl herself is female.

Similarly, "the spoon" (no sex at all) is "die Loeffel" (feminine gender) *.

* (Sorry about no double dot over the a or the o)

[Pete 2]

Sex? gender? What about the other two?

Yes, the *first* definition (according to my OED) of gender is a technical term used in grammar. However the next definition is the property of belonging to such a [gender] class and the colloquial third definition is "a person's sex".

Also, regarding your examples. I think a fair few people will agree that spoons (no sex at all) does often lead to sex. Which is really what I wanted to steer the post around to.

Don't really care what that means in german, language gender is a completely different thing.

Sorry to be so German, but...

... it's 'der Loeffel'. Stick that in your Wikipedia and smoke it!

[Anonymous Coward]

Well,

as we are wearing the four-cornered hat already:

"Löffel" is actually of masculine gender, and so the singular goes with "der".

"die Löffel" is _plural_, and the plural article is "die" for _any_ gender

sg. .................. pl.

der Löffel -- die Löffel

der Mann -- die Männer

das Haus -- die Häuser

die Frau -- die Frauen

Mark Twain on language and gender

To quote the very excellent writer Mr. Mark Twain, on the subject of "The Awful German Language":

"In German, a young lady has no sex, while a turnip has. Think what overwrought reverence that shows for the turnip, and what callous disrespect for the girl."

linguistic gender != sexual gender

It's all about the timing....

Sex......is what happens before you get your gender. Typically the gap is around 9 months

{{original research}}

If you edit for a while (or even just tagging articles as needing attention) you're bound to attract other editors' attention, some of whom are the stereotypical overzealous young male. You know the type, heck most of us here will have been such at one time or another: Freshly high on the awesomeness of their pet project and more capacity to find fault with others than in moderating their own actions.

I imagine that girls are less likely to pick up something like wikipedia for their pet project needs and are more easily put off by having their contributions be not so subtly "improved" away, or "helpfully" criticised into oblivion. And of course the fair sex automatically attracts fair amounts of attention and thus more scrutiny on their works.

Of course, the above is all speculation and even if true I wouldn't know what to do about it. Maybe ze big jimbo can come up with something original. Or not, as the case may be.

Wiki Circle Jerk

Wikipedia long ago became a clique so it wouldn't surprise me if it is as male dominated as most other institutions are with their 'I know best', other males tolerated but considered inferior, and women can just sod off back to the kitchen arrogant attitudes.

The question is; are women locked-out and discouraged or just disinterested in playing the Wikipedia game?

[Anonymous Coward]

re: Wiki Circle Jerk

Couldn't have described Wikipedia any better. Most articles being maintained by a bunch of immature males and the rest being corporate PR propaganda. Try and point out an obvious inexactitude and you immediately get shouted down and/or banned, mainly because you're not a member of the clique or the truth doesn't match some corporate propaganda line.

[Pete 2]

Doesn't exist

Well I checked Wikipedia for an article called "Male bias in articles" and got the response: "The page "Male bias in articles" does not exist"

Should we therefore assume that since Wiki doesn't have an article for it, it doesn't exist?

[Anonymous Coward]

Creating new articles isn't hard...

... but keeping them is something altogether. If you would sit down and do a wikipedia writeup of this research, you could expect jimbo's self-selected selective semantics sodomists to shoot it down because that's a "primary source", and not sufficiently hear-say to include in wikipedia.

[Anonymous Coward]

Or....

..women are just crap at providing detailed info on any subject..ask any married man.

[Ru]

Hrm

So, does wikipedia's little echo chamber, deliberately or otherwise, exclude known female editors? Can it tell an editor is female just from their writing? Or are its actions fundamentally offensive to the female psyche? That would be entertaining.

Maybe the fairer [citation needed] sex is simply less interested in contributing to what is largely a collection of technical articles with a scattering of noticably poorer quality nontechnical content, given the general trend of women to study and work in non-technical fields in the english speaking west, which is where most contributors seem likely to live.

[Jedit]

"Can Wiki tell if an editor is female from their writing?"

If they're writing about friendship bracelets and/or Sex in the City, then the answer is an unequivocal "yes".

(Paris, because more people have looked her up than have looked her up on Wiki.)

"friendship bracelets or Sex and the City"?

I didn't realise only teenage girls counted as women on the internet?

My idea of a more female-biased article would be either about female health or, being a little sexist perhaps, beauty products. OK, so that's almost as stereotypical -- but at least they're things common to at least some women in all age groups an cultures and not just Western teenagers.

[Anonymous Coward]

Re: I didn't realise only teenage girls counted as women on the internet

Are you kidding? Everyone (even guys) count as women on the internet!

Did SitC have a teenage demographic? If so, is the demographic STILL teenage? I'll be honest, I have no idea what it's demographic is. I think a more interesting question then "what percentage of SitC's audience is female?" is "What percentage of females are SitC fans?"

Girls bullied on nerd forum?

That would run contrary to experience, perhaps wiki editors are unlike any of the nerds on every other internet forum but I doubt it.

Could be the women don't want to argue, hide the fact they are women if they have any sense and aren't used to being corrected when wrong (it is the ones without sense who own up to being a woman remember).

Then the clincher, women just don't want to edit a wiki.

Lets face it, most guys have better things to be doing than editing a wiki, what kind of swamp monster must the women on their be?

[Galidron]

Girls bullied on nerd forum

It's not that uncommon for nerds to try to push women out of their groups. Some of them are very resentful against the opposite sex. Some believe that women shouldn't be allowed to participate in whatever particular nerdy activity they are involved in. Others just drool too much which isn't the same as bullying but I imagine is a bit of a turn off.

I think some of it is because some nerds blame women for not having any interest in them. After all it couldn't be related to their social skills because they get along with each other just fine.

Full Disclosure, I participate in several different activities that would likely put me in this category.

[Jim 59]

Staggering

Most silicon chips are designed by men too. I know, I can hardly believe it either. Anyone who wants to change that could start by encouraging girls to study engineering. Good luck with that.

[Ru]

Lack of female engineers

is a largely english-speaking western cultural issue. Russia and China do alright, for example. There's nothing fundamentally alien about women working in highly technical fields.

I know a british female Verilog coder; she observes that the lack of female engineers in the industry means she can pretty much walk into a company, say 'gizza job' and they'll fall over themselves to provide very competetive salaries and reward packages. She's not unhappy about the lack of competition, but doesn't quite understand why some many of her peers went into mediocre jobs in law, media, journalism and the like where they don't make big bucks and don't stand out from their peers.

Meh

There are a large number of clique-ish, angry nerds on there who will delete pages and revert information that goes against their political views, or is decided quite arbitrarily not to be notable enough.

I watched a friend's page get deleted because of notability concerns (he's had three novels published recently) while there's a page for every bit-part character in the most obscure anime/manga you can think of....

Yeah, it's populated by the absolute worst sorts of geeks and I can well imagine rampant sexism in the mix there too.

[Rovindi]

Notability Concerns

A friend of mine, a publisher, had his page modified to say he had died. Being upset about this, I rang him to ask him about his death and how it would affect his short-term plans and whether we were still on for a beer on Friday.

Despite not being dead, the numpties at Wikipedia initially refused to change it, citing "notability concerns". After a whole raft of emails, which have been become legendary in our circle, as well as pictures of him with that days Evening Standard etc., they relented.

You can´t make this shit up.

[Steen Hive]

8.3% of Encyclopaedia Britannica's

[Anonymous Coward]

Not sure if trolling or just very clever.

I'm not sure if 16% isn't pretty good, compared to the general background of male domination of the internet and technology firms and projects. I can't think of, e.g. any open source projects that have reached that degree of female participation, and in a long career as a programmer I've never worked anywhere that managed to recruit that many female programmers.

We fail pretty hard as an industry.

However as a bloke the three female bosses I've had have been ten times better than the five males bosses I've had. No it's not some lurid little workplace, domination trip, they just made working for a living slightly more pleasant than having to deal with all that alpha-male, bloke-shit.

Not all bias is a bad thing.

'As Wikipedia continues to be a critical information resource, it is important that all voices be heard.'

Err no. If Wikipedia is a critical information resource it is important that the most intelligent and knowledgable men and women on that subject are heard. Reading the comments thread of almost any video on YouTube shows what happens in the internet when all voices can be heard.

[Anonymous Coward]

[Loyal Commenter]

Maybe...

It's because any person who has spent enough time watching Sex in the City to be able to write a wikipedia article on it would either be confined to a small comfortable room without access to electricity, let alone the internet, or would already have taken their own life?

In my (perhaps limited) experience, women aren't particulalrly underrepresented on the internet, but they seem to spend most of their time alternating between facebook and ebay.

The fact that few technical articles on wikipedia have much female input is perhaps more a reflection of the general lack of women working in technical fields. For example, in my career as a software developer, which has stretched over more than a decade, I have met exactly two female programmers, one of whom was technically very adept, and one who wasn't. I'd be very surprised if the percentage of women in this field reaches double figures. This is not due to lack of ability, rather than lack of interest. This is a pattern that is reflected in many technical areas, and if you want to change it, you first have to change popular attitudes (including those amongst women specifically) towards what is considered appropriate work for women. Good luck with that.

It is also worth noting that gender bias works both ways, and there are very few males working in areas such as nursery nursing. This is in part due to the attitude society takes towards men working in such roles, viewing them with suspicion.

Hmm

The mayor of Washington, DC, is a confessed "Sex and the City" fan. This did not seem to hurt him in the primary, I suppose because a majority regarded his opponent, the incumbent, as a jerk.

... you can't edit anything on there for love nor money... whatever you write will removed and classed as vandalism even if its is nothing of the sort. The editors just have different opinion about the subject and use the editor rights to revert changes.

Also if the dude in the red chinese shirt (why is he always pictured like that, it makes him look like a twat) want anyone other than nerds and geeks to write wikipedia articles he should make the thing understandable to normal people... does anyone understand what they see when they try and undo something?

[Steven Roper]

I gave up trying

to contribute to Wikipedia years ago. I once spent days on there going through correcting spelling and grammatical errors, not even adding or altering the factual content. Nor did I "correct" American spelling - I was merely correcting genuinely misspelled words and grammatical errors.

After discovering that the vast majority of my edits were being reverted to the erroneous versions by snot-faced little elitist pricks with an editorial superiority complex, I told them to go fuck themselves, got banned for my pains, and haven't been back since.

The only thing I use Wikipedia for now is to get the source websites listed at the ends of the articles for information. I wouldn't take anything from Wikipedia itself as gospel.

[Anonymous Coward]

Well done Chris Jasper for finally mentioning that

The involvement of people in anything that doesn't result in personal gain is a type of sickness. What will they say when they die? "I spent 1/10 of my waking life working on some open-source project that is now totally obsolete, wow I feel really good about that". In return I got a few 'virtual' thanks, didn't make any friends (at least not the type that I could have a beer with), and totally f**ked up my eyes, neck and back in the process, when I really should have been making the most of my free time to play sport, spend time with the kids (perhaps even... *have* some kids). You get the idea? Women, quite simply, don't suffer from the sickness. They're self, self, self, unless it's some community-based thing, in which case their contribution is highly visible, resulting in more friends, more people to share gossip with and so on. I'm sure I'll get shot down for my stereotypical view, but we have plenty of women at work (programmers), but they do it as a job. They don't take it home. They have better things to do, so really there is no reason for them or anyone else to complain about a lack of representation.

I have long suspected..

..that's why women are under-represented in computer programming. They aren't as easily fooled by computers as us men. I think we get some kind of 'social interaction' kick from them. Women being more accomplished social animals means that they don't get that same kind of kick. To them a computer is just a bloody complicated machine and only an idiot would bother to spend all day 'communicating' with one.

I've known three female programmers during the 25 years I've been doing it and all of them were very good at programming. They seemed to take it more seriously though and were interested in the theory which is part of why I came up with my theory. Most male programmers prefer to leap in and start typing (experience gradually weans you off the habit). None of the three women I knew did that. They always planned things out thought and didn't start work until they had a clear idea of what they wanted.

[Anonymous Coward]

The reason women are under-represented in computer programming

.. is that women are under-represented in computer programming.

The 'Let's get more women into computing' campaigns completely miss the point and are doomed to failure, not that so-called industry 'experts' seem to have noticed any time during the last 30 years.

Still waiting for the 'Let's get more of a less pathetic type of man into computing, so that women will then follow naturally' campaign.

Faulty reasoning

"In general on the internet it's safe to assume that a fair number of people claiming to be female are actually men or teenage boys, so this would suggest that only a tiny proportion of Wikipedians are genuine ladies."

I'd argue that the opposite probably applies to Wikipedia. There's little to no advantage to be a male pretending to be female on Wikipedia, in fact, the popular perception that females have less input there would even work against it. There are probably a fair number of female masquerading as men there.

Instead of looking at what gender Wikipedia users identify at, it would be much more instructive to isolate ways women and men compose their language (yes, there are differences), and put some algorithms together to see how that runs across Wikipedia articles in general. I suspect the results would be a lot more even.

[Steven Roper]

"isolate ways women and men compose their language"

There is a site that does this:

http://www.hackerfactor.com/GenderGuesser.php

This site takes a block of text and uses statistical analysis to determine the probability of it being written by a male or a female. In my own tests it has proven to be remarkably accurate - on the order of around 85-90%. While this is still a significant margin of error, it is still far more accurate than determining the author by their stated gender identity. Consider that a lot of women would identify as men in order to avoid being hit on or discriminated against, and a significant number of men would identify as women in order to get free gifts and such. I know from running a female character in WoW that people are much more willing to give gold, gear and help to someone they perceive as female than they are to a male!

So the error factor resulting from false gender self-identification would be considerably greater than the 10-15% error exhibited by that analysis site.

If you've got the time, feed some wiki articles into it and let us know what you find.
