PHILADELPHIA It seems that the heart wants what the heart wants and it can figure it out fairly quickly, according to evolutionary psychologists at the University of Pennsylvania.

"Some people say they're looking for one kind of person, then choose another. Other people say that don't even know what they're looking for.

"People generally understand their own worth on the dating market, so they are able to judge each others' potential compatibility within moments of meeting."

At each HurryDate party, roughly 25 men and 25 women interact with each other for three minutes at a time. At the end of the session, each participant indicates which of the people he or she met would be of interest for the future. HurryDate also collects survey data from participants, including age, height, education, income, drinking behavior, smoking behavior, race and religion. For this study, HurryDate also collected answers to optional questions about such things as how participants rate their own attractiveness and sexuality.

"Although they had three minutes, most participants made their decision based on the information that they probably got in the first three seconds," Kurzban said. "Somewhat surprisingly, factors that you might think would be really important to people, like religion, education and income, played very little role in their choices."

Psychology has often viewed relationships as transactions where people select mates based on substantial qualities a mate has to offer, such as power and money. According to Kurzban, the data show that, when people meet face-t
