Mysteries of Mate Choice

[exams]

HOW DO WE CHOOSE romantic partners? The question has long interested sociologists, who traditionally looked to marriage records for answers. These widely available records generally offer useful demographic information on those who tie the knot, including their racial background and education level. But in an era of rising divorce rates and increased cohabitation, when people typically wait longer to marry and same-sex couples canÃÕ marry in most states, marriage records donÃÕ give a complete picture. After all, marriage is only one possible outcome in the complicated process of choosing a mate, and marriage data canÃÕ capture the forces that draw people together in the first place, such as shared passions for the Red Sox and Downton Abbey. Fortunately for researchers, the increasingly popular world of online dating offers a largely untapped gold mine of information on how people pair up, says Kevin Lewis, a doctoral candidate in sociology who reviewed data from the 1.8 million people actively using a popular Internet dating site, OKCupid, during the fall of 2010. The site provides not only basic demographics like race and religion, ÅÃut also body type and height and whether or not you have or like pets or children, Lewis says. ŵhese things are obviously very important for mate choice, but we donÃÕ usually have data about them. The database includes details of which users contacted others to express interest, and who responded to those messages. Online dating is worthy of study, Lewis says, because it provides sociologists with new ways to observe ÅÕhe extent to which individuals of different backgrounds accept each other as equals. These data offer one of the first opportunities to analyze the earliest stages of mate selection, when users decide which groups they will and wonÃÕ consider in the vast pool of potential partners, revealing much about current social boundaries. The data also allowed Lewis to test two long-standing theories about mate selection. One body of research suggests that we prefer similarity in a partnerÃÔomeone who mirrors our racial background, education, or religion. Other researchers contend that we usually seek partners with higher status, including those with more education or income. Lewis focused on a baseline population of 165,000 U.S. residents who were single, heterosexual, seeking to date, and using the site for the first time, and then zeroed in on the subset of 7,671 individuals with New York City zip codes. Using multivariate modeling techniques, he found that both similarity and status play a role, but Ã…Ã…ifferentially so, depending on whether youÃÓe male or female. Most users in his sample did prefer partners from a similar social background, but Lewis also observed some ÅÉighly gendered status hierarchies? for example, women tend to seek men with more education and more income, while men prefer women with a college education, Ã…Ão more and no less. White men, he adds, maintain a privileged position, receiving the most initial messages, while black women receive the fewest. The model revealed that people with traits that are uncommon on OKCupidÃÕhose who have several children, for example, or admit to being overweightÃÂre especially likely to flock together. One of LewisÃÔ favorite examples: people who describe their body type as ÅËacked or muscular. Ÿe donÃÕ know if this is just because people prefer similarity in body type, he says, Ã…Ãr if this is a proxy for people who clearly spend a lot of time in the gym and want a partner who shares that passion. But this is another group that self-segregates. His most surprising finding involved differences in the way people initiate contact with potential partners and respond to interest from others. In initial contacts, similarity rules, he says. ŪÃÎ very, very statistically unlikely to contact someone of a different racial background, he explains. Å£ut in the unlikely event that someone from a different racial background contacts me first, IÃÎ actually significantly more likely to reply than I would to someone from the same background. Lewis believes that when someone steps over social boundaries to connect with us, weÃÓe particularly interestedÃÂnd that can cause even sturdy boundaries to ÅÕotally disappear. The currently unattached scholar says his own experiences on dating sites have aided his research. For example, some critics have said itÃÔ wrong to assume that people like each other based on the mere fact that theyÃ×e traded messages. Lewis disagrees. Å¢nyone whoÃÔ been on a site for more than a day or two knows that polite rejections donÃÕ really happen, he says. Ūf youÃÓe not interested, you just donÃÕ reply. But useful as his own online foray has been, he admits that initially it wasnÃÕ Ã…ÃŽotivated by research concerns. It was motivated by a distaste for being single. http://harvardmagazine.com/2012/05/mysteries-of-mate-choice
