Facebook's Gaydar: is it accurate?
Several news sources have started reporting on a 2007 research project by a group of MIT students who found they could accurately predict Facebook users' sexual preferences based on the people they were friends with. The project, referred to as "Gaydar," sampled data from 1,600 men (only 33 of whom were out as gay on Facebook) to create an algorithm that supposedly predicts whether a user is gay or not. However, the research methodology behind this unpublished study seems a bit dubious to me.
The initial test of Gaydar correctly predicted that 10 of the researchers' friends - who weren't "out" on Facebook - were gay. That's a pretty decent success rate, but a tiny, tiny sample size. Only 33 gay men out 1600 total can't possibly be reflective of the entire population. According to Wikipedia, 4% of voters in the last US election self-identified as gay, lesbian, or bisexual. Assuming that those numbers are pretty conservative, only 2% of the people in Gaydar's initial sample were gay. I'm not convinced it's really time to start panicking that you could be inadvertently outed based on your Facebook friend list.

This study is pretty stupid. The "Gaydar" basically checks if the majority of your friends are gay. Well that seems kinda obvious.
In my case, I'm a computer engineer. Someone could easily look at facebook and see that a lot of my friends are also computer engineers and come to the conclusion that I am one. Simply put, people tend to be friends with people who have similar viewpoints.

Oh, totally. Being a closeted gay man is *exactly* like being a computer engineer. Well, except for that whole same-sex attraction thing. Oh, and the can't get married thing. And, the no equal protection under the law thing. Aside from that it's *precisely* like being a computer engineer.
Wait, what?
RocketboySep 22nd 2009 2:01PM
Wow, Grant misses the point again.
Maybe this will help...
If you like Anime, there's a good chance that on your social network sites, you'll befriend a lot of Anime fans.
If you like Death Metal, there's a good chance that on your social network sites, you'll befriend a lot of Death Metal fans.
If you like douchbag, there's a good chance that on your social network sites, you'll befriend a lot of douchbags.
And where is this law that says that only straight people can be married? Or that that they don't get 'equal protection under the law'? Do young people get the same type of age discrimination protection that old people do? Or do men with European ancestry get the same gov't grant opportunities that women, or people who do not have a European ancestry?
Please define how 'equal' you are expecting the protection of the law?

The more you troll our comments, the more I just feel sorry for you.
Seriously, good luck with whatever it is that's so deeply and disturbingly wrong with you.
AnthonySep 22nd 2009 5:35PM
Funny, Grant, I was just about to say the same thing to you. Go back to the bridge from whence you came, troll. Someone correct me if I'm wrong, but, isn't a troll someone who reads articles just to comment on other people's comments? Somewhat like you are doing? (See "TMI comment of the year award" comment made at 1:44pm)
Jay HathawaySep 22nd 2009 5:58PM
Hey Anthony, I think Grant reads these articles because he's Download Squad's lead blogger. Reading our stuff and caring what we post is part of his job. You could be absolutely right that he's trying to instigate something, but he's not a troll under your definition.
RocketboySep 22nd 2009 6:50PM
Grant... A troll is defined as (or at least, grouply defined in Wikipedia as), "a troll is someone who posts controversial, inflammatory, irrelevant or off-topic messages in an online community, such as an online discussion forum, chat room or blog, with the primary intent of provoking other users into an emotional response[1] or of otherwise disrupting normal on-topic discussion.[2]"
So let's see...
controversial? No, but I think your post is defined by that.
inflammatory? Maybe to you, but in response to an inflammatory comment made to someone just pointing out something.
irrelevant? It was you who was trying to make the OP sound like he was saying.. wait, let me use your words "Being a closeted gay man is *exactly* like being a computer engineer."
off-topic? Wow, totally. Fully and completely off topic. OP posted that it's common sense that people with the same belief systems, likes, dislikes, political stances, careers, etc. tend to migrate toward each other.
emotional response? I'm sure I got one out of you, but that was not the intent. I'm sure it received a lot less of an emotional response than your post. I didn't go out of my way to try to make someone look like an idiot. I just pointed out when someone did.
otherwise disrupting normal on-topic discussion? You better believe that's what your post was. And, strangely enough, my post was very on topic.
So who was the troll again?
It's not like I set out every morning to reply to something you wrote Grant. But you just make it so easy for me to find something dumb you wrote.
All I know is, that if I was the OP, I'd be quite pissed at your accusation. Instead, I'm delightfully amused.
And of the 1000+ comments I've made on the weblogs sites (I've been reading for a long time, what can I say... the count is not due to frequency of posting...) this is probably maybe only the 2nd time someone accused me of being a troll. So I think my track record is rather clean.

This is pretty stupid. These algorithms are also used for advertising site and cookies. My wife and I are kinky and often on FetLife and fetish sites and the advertising engines think we are gay. Also in the fetish community we tend to have more gay and lesbian friends than in the vanilla world. Of course our TiVO thinks we're gay too, LOL.

Wow. TMI comment of the year award?
Thanks for sharing, Enigma!

I could have made it worse, but I won't!!!

Do you believe the facebook community's makeup directly correlates that of registered voters?
Jay HathawaySep 22nd 2009 5:53PM
I don't think Facebook users and voters correlate strongly at all. I just think voters, surveyed as they're leaving the polls, are even less likely to accurate report their sexual preferences than FB users are.

@Rocketboy: "And where is this law that says that only straight people can be married? "
It's called the Defense of Marriage Act (DOMA). It was signed into law in 1996 and states that the federal government defines marriage as a legal union exclusively between one man and one woman.
As for equal protection under the law you can be fired from your job for being gay in 27 states, and denied housing for being gay in 36 states. So yes, I would say that there is not equal protection under the law for gay people in this country.

"It's called the Defense of Marriage Act (DOMA). It was signed into law in 1996 and states that the federal government defines marriage as a legal union exclusively between one man and one woman."
Ok, and where does it say that it states that it's a legal union between one straight man and one straight woman?
If you want to make the argument that two men or two women cannot get married, that's a valid argument to make. To say that homosexuals are not allowed to marry is a lie.
RocketboySep 22nd 2009 6:54PM
Oh, and sorry for the double-post... but where is the law that says that you cannot be denied housing, or fired from a job if you are straight?
If I tried to move into an apartment in a gay section of town and I was denied an apartment because I wasn't gay, do you think that anyone would come to my defense?
That's all I'm saying about equal protection of the law. Of course I don't think that you should be fired if you are gay. Of course I don't think you should be denied housing because you are gay. It's just that equal protection means just that. Equal. Not special.
Grant RobertsonSep 23rd 2009 10:57AM
Seriously, you could just Google this stuff.
The law that prevents you from being denied housing is The Fair Housing Act of 1968.
http://www.hud.gov/offices/fheo/FHLaws/index.cfm
For work related issues, there's the Civil Rights Act of 1964. And the issue isn't whether you can be "fired from a job *if* you are straight." The issue is that you can't be fired just *because* you're straight. As in, I can't fire you with the justification being "He's a heterosexual".
In just about every state, I *can* legally fire you with the reason "He's a homosexual". Not, "He's a lousy worker" or "He shows up late" but, "He's a homosexual, who otherwise is a good employee. I just don't want his kind around here". No other group can be treated that way legally. If I discover you're Jewish, or Christian, or Buddhist after I hire you, I can't fire you for that. If I discover you're a member of the KKK or, The Sons of Confederate Veterans, I can't fire you for that.
http://www.eeoc.gov/policy/vii.html
In fact, to tie this back to the original post, there is likely nothing stopping your employer from running this "Gaydar" algorithm against your list of Facebook friends, establishing that you're possibly gay, and firing you on the basis that they *believe* you to be a homosexual.
Beyond that, I'll just say again, I feel really sorry for you. It's quite obvious that your mouth is far more open than your mind.
RocketboySep 23rd 2009 12:13PM
*sigh*
Did I not just post above that I don't believe that being gay is cause to deny a job or housing?
All I'm saying, that there should be no such thing as a 'protected class'. If it's wrong to deny someone something for one reason, it's just as wrong to deny the same person the same thing for the inverse of that reason.
But that would require reading comprehension, and I cannot expect that from you Grant.
For every hate crime committed, there's another one that's not considered a hate crime, because it's only applied when A does something to B, but not when B does something to A.
Many times, someone is arguing for special rights under the call of equal rights.
Is it close minded to expect equal to actually mean equal? To you, it must be.
LarfSep 22nd 2009 5:17PM
The fun thing is.. that as a gay person.. I use the same type of concept.. to figure out who has HIV or not.. A lot of times people with HIV only hang out with other people with HIV.

This story is totally ghey.

Rocketboy, you are just not listening. I suppose you believe the earth is flat and the sun revolves around it and the moon is made of cheese. I could tell you that is not true, but you wouldn't listen anyway.
