Online dating secrets as revealed by math majors

"I happened to know a senior guy at an online dating site," Ramaprasad explains."Since he knew that I studied online behavior, he suggested, 'Why don't you study this?They were also more likely to check out potential same-sex and interracial matches.

This was especially true for female users: those with anonymous browsing wound up with an average of 14% fewer matches. Women don't like to send personal messages to initiate contact, explains Jui Ramaprasad, an assistant professor of information systems at Mc Gill University's Desautels Faculty of Management.

In other words, she says, "We still see that women don't make the first move." Instead, they tend to send what the researchers call a "weak signal." "Weak signaling is the ability to visit, or 'check out,' a potential mate's profile so the potential mate knows the focal user visited," according to the study.

The researchers expected the anonymity feature to lower social inhibitions—and apparently it did.

Compared to the control group, users with anonymous browsing viewed more profiles.

"The offline 'flirting' equivalents, at best, would be a suggestive look or a preening bodily gesture such as a hair toss to one side or an over-the-shoulder glance, each subject to myriad interpretations and possible misinterpretations contingent on the perceptiveness of the players involved.

Much less ambiguity exists in the online environment if the focal user views another user's profile and leaves a visible train in his 'Recent Visitors' list." Men often take the cue.

(Backus based his formula, for instance, on the assumption that he’d find only 10% of the women he meets agreeable and only 5% attractive.) In fact, this “price of admission” problem is also at the heart of a chapter probing the question of how you know your partner is “The One.” Fry writes: Indeed, some such mathematically minded people have applied an area of mathematics known as “optimal stopping theory” to derive an actual equation that tells you precisely how many potential mates to reject before finding the perfect partner and helps you discern when it’s time to actually stop your looking and settle down with that person (P): Fry explains: It tells you that if you are destined to date ten people in your lifetime, you have the highest probability of finding The One when you reject your first four lovers (where you’d find them 39.87 percent of the time).

If you are destined to date twenty people, you should reject the first eight (where Mister or Miz Right would be waiting for you 38.42 percent of the time).

"Men send four times the number of messages that women do," says co-author Akhmed Umyarov, an assistant professor at the University of Minnesota's Carlson School of Management.

"So the anonymity feature doesn't change things so much for men." Implications beyond online dating Experiments of this sort could be used in a range of online-matching platforms to help understand how to improve the consumer experience - though it's important that the experiments be done ethically, the researchers say.

Scientists’ current estimate is that our galaxy contains around 10,000 intelligent alien civilizations — something we owe in large part to astronomer Jill Tarter’s decades-long dedication.
