All she has to do is sit there and judge her date. The study concedes the result might be different if the woman takes the offensive and the male awaits each supplicant.
Researchers at Northwestern University reversed the roles and found when the females went from male to male, thus putting the guys in a position of power, there was no gender difference in pickiness.
"The mere act of physically approaching a potential partner, versus being approached, seemed to increase desire for that partner," psychologist Eli Finkel said in releasing that study in 2009.
The ideal result of speed dating, of course, is to have both participants decide they would like to take the next step.
Then an email address or phone number could lead to a real date.
But it doesn't happen all that often.
McFarland said only about 20 percent of the Stanford dates resulted in a "match," but of those only about 9 percent actually contacted each other. And a month later, only nine "pairs" were actually dating. That's after nearly 1,000 speed dates.
So the odds may not be all that great, at least among sophisticated, well educated, and probably wealthy and beautiful grad students. McFarland had this bit of advice:
"Females are more selective than males, and if you really want to hit it off with a female, you make her engaged, you support what she says."
And remember, in the long run, "it's more than just what you look like."
So watch your language.
