Use Your Web Browser's History to Identify Your Gender
Believe it or not, your browser might know more about you than even your spouse. Whether you use Firefox, Internet Explorer, or any of the several alternative browsers, a peek in your browsing history reveals what games you're playing, where you shop, what you shop for, where you booked your upcoming vacation, and it even knows what turns you on. But up until now, your browser had no way of knowing whether you're a male for female. Not anymore.
Mike Nolet, CTO and co-founder of AppNexus, has devised a nifty little algorthm that analyzes your browser's history and then predicts your gender probability. The code comes from a modified version of Paul Cook's Social History javascript, and with a little bit of tweaking, Nolet has made it capable of predicting whether you're a male or female. But just how accurate is it? After quickly analyzing the sites I had recently visited (it works much faster on Firefox than IE), the likelihood of my being male came back 100 percent. Save for this one Halloween party in college, that's pretty damn accurate. And eerie. Are there really no women who dig shopping at Newegg, throwing down cards at Pokerstars, and drooling over Kawasaki's 2008 sport bike lineup?
Try it out for yourself and post your results below.

Likelihood of you being FEMALE is 13%
Likelihood of you being MALE is 87%
Site Male-Female Ratio cnet.com 1.56 reuters.com 1.99 pandora.com 0.9 tomshardware.com 2.33 Well, not exactly accurate when you consider that I'm a female gamer who is currently looking into rebuilding her PC. Plus I was on other sites today that this algorithm did not pick up, like newegg.
Oh well, I'm secure in my feminimity. :-)

I wonder if it guesses your a chick when you know that your a man if that means that you have a predisposition to homosexuality or if it's just plain wrong?
Likelihood of you being FEMALE is 33%
Likelihood of you being MALE is 67%
Site Male-Female Ratio divx.com 1.99 I ran Ccleaner befor running this and this is the result.
I wonder what it would come up with if I visited porn and liberal websites. Perhaps visit Obama's site and then run the Algorithm. I'll be back

No difference. It says that it uses the male/female ratios from the top 10k websites. I guess my top 10k porn sites are not counted as the numbers did'nt change and neither did they change after visiting liberal websites and Obamas website.

I don't need to run the script, the picture Paul put with this article sums up the gender divide in this household perfectly lol. My wife laughed as hard as I did when I showed it to her.
Our computer room is often filled with the lilting melodies of Diner Dash 27, peppered with cries of "Tango down!" ;)

it's just that at lot more women then men like to cook. Although to be fair most famous chefs are male (at least in the books that I read, don't know about the real world since i don't eat at restaurants. That is because i'm 15 and my mom makes very good food).

Had your cache/history been cleared recently, or perhaps automatically at work whenever you close the browser? If there's no history, it will spit out a 50/50 probabilty, which I suppose one could argue is inaccurate if factoring in the number of male vs female computer users.

Spot on, though I'm not sure how it works. The list of sites and the ratio numbers are just gibberish to me.
