Okay, here's something totally weird: I ran across a site that analyzes your browser history and uses a mathematical algorithm to identify your gender. According to this algorithm, I am male;
Likelihood of you being FEMALE is 6%
Likelihood of you being MALE is 94%
Hrm. Do you suppose this is the reason my email boxes are all jammed with ads to increase my penis size? How about you? Does your browser history predict that you are male or female?

GrrlScientist is an evolutionary biologist, ornithologist, aviculturist, birder and freelance science and nature writer. A native of the Pacific Northwest, she relocated from Seattle to NYC with her parrots after earning a BS in Microbiology (emphasis in Virology) and PhD in Zoology (Ornithology) from the University of Washington. In NYC, she was the Chapman Postdoctoral Fellow at the American Museum of Natural History for two years, pursuing part of her "dream" research project by reconstructing a molecular phylogeny of the parrots of the South Pacific islands. GrrlScientist and her five parrots are currently relocating to Germany, where she will continue writing her blog while also writing a book and learning German. (Meanwhile, her parrots will continue to nibble on her extensive personal library.)

I've no idea I was at the Torygraph recently - it's not a site I frequent very often.

I have a 67% likelihood of being female, having recently visited the female-dominated Myspace, Livejournal, Facebook, Current.com and Southwest Airlines.
I can kind of get why social networking sites have more female than male visitors, but it seems odd that the male-female ratio for southwest.com is 0.77.

It guessed my gender correctly, which didn't really surprise me, as I spend a lot of time at knitting/crocheting websites (although none of them turned up on my "list"). I've fooled other gender-guessing internet thingies before, but apparently my browsing habits are girly. :D
On the whole, though, I find myself deeply unimpressed with this system, since the websites that turned up on my list are not at all representative of where I spend my time:
Likelihood of you being FEMALE is 78%
Likelihood of you being MALE is 22%

ebaumsworld.com
1
michaels.com
0.47
netzero.net
0.89
I've been to netzero and ebaumsworld exactly ONE time each, and none of the other sites are ones I visit regularly, except Amazon. Well, and Webkinz, because my son goes there a lot. But none of the sites where I spend most of my time turned up here.
I will also say that I'm laughing about Mapquest being considered a girly website (unless I'm misreading the ratio thingy) . . . is it really true that men still won't ask for directions, even from the internet? ;)

I have 73% chance of being male which a 71 year old retired lady is kind of uplifting.

GS - Why on Earth did you subject yourself to this in the first place?!! I flat refuse to encourage dumb (and in this case sexist) surveys as a matter of principle.
Bob OH - "it's not a site I frequent very often"
Do you want to rephrase that? It's too early in the morning for my mind to be played with so cruelly!
