Really. They don't. You're astonished, right? I mean, you were lying awake at night, wondering about that, weren't you?
I feel so proud of the dear old place.
In case you were wondering how they figured this out, here is the summary:
[Dr. Provost] analysed the gait of female volunteers, showed video clips to 40 men, asking them to rate the attractiveness of the way the women walked, and then matched the results to the hormone tests.This being a university, of course the test subjects were no doubt all undergrads recruited to make a few bucks in the cause of science. Think about that one for a minute: you're a 20yo male, and someone asks you to spend a few hours watching videos of campus babes strutting their stuff, and rating them on it.
And for this they're actually going to pay you?
There is of course a postulated explanation:
She now thinks the findings tally with other research suggesting that women want to conceal their ovulation from males other than their chosen partner. A sexy walk would be too obvious, so women are thought to use changes in smell and facial expressions that can be experienced only at close range.
Hmmm...smacks a bit of Evolutionary Psychology to me. I ain't opening that can of worms. Besides, what I really want to know is: why weren't they doing that kind of research when I was an undergrad?
