The Scientific Flaws of Online Dating Sites
Indeed, the people who are most likely to benefit from online dating are precisely those who would find it difficult to meet others through more conventional methods, such as at work, through a hobby, or through a friend.
Singles browse profiles when considering whether to join a given site, when considering whom to contact on the site, when turning back to the site after a bad date, and so forth.
The answer is simple: A series of studies spearheaded by our co-author Paul Eastwick has shown that people lack insight regarding which characteristics in a potential partner will inspire or undermine their attraction to him or her see herehereand here.
The straightforward solution to this problem is for online dating sites to provide singles with the profiles of only a handful of potential partners rather than the hundreds or thousands of profiles that many sites provide. But how should dating sites limit the pool?
Here we arrive at the second major weakness of online dating: These claims are not supported by any credible evidence. The first is that those very sites that tout their scientific bona fides have failed to provide a shred of evidence that would convince anybody with scientific training.
The second is that the weight of the scientific evidence suggests that the principles underlying current mathematical matching algorithms—similarity and complementarity—cannot achieve any notable level of success in fostering long-term romantic compatibility. It is not difficult to convince people unfamiliar with the scientific literature that a given person will, all else equal, be happier in a long-term relationship with a partner who is similar rather than dissimilar to them in terms of personality and values.
Nor is it difficult to convince such people that opposites attract in certain crucial ways. Indeed, a major meta-analytic review of the literature by Matthew Montoya and colleagues in demonstrates that the principles have virtually no impact on relationship quality. Similarly, a 23,person study by Portia Dyrenforth and colleagues in demonstrates that such principles account for approximately 0.
To be sure, relationship scientists have discovered a great deal about what makes some relationships more successful than others. For example, such scholars frequently videotape couples while the two partners discuss certain topics in their marriage, such as a recent conflict or important personal goals.
Such scholars also frequently examine the impact of life circumstances, such as unemployment stress, infertility problems, a cancer diagnosis, or an attractive co-worker. But algorithmic-matching sites exclude all such information from the algorithm because the only information those sites collect is based on individuals who have never encountered their potential partners making it impossible to know how two possible partners interact and who provide very little information relevant to their future life stresses employment stability, drug abuse history, and the like.
So the question is this: Can online dating sites predict long-term relationship success based exclusively on information provided by individuals—without accounting for how two people interact or what their likely future life stressors will be?
Well, if the question is whether such sites can determine which people are likely to be poor partners for almost anybody, then the answer is probably yes. Indeed, it appears that eHarmony excludes certain people from their dating pool, leaving money on the table in the process, presumably because the algorithm concludes that such individuals are poor relationship material.
The Scientific Flaws of Online Dating Sites - Scientific American
Identifying problems and deciding how to fix them is crucial for users looking for love, but now it's good for business, too. Match alone has 2. Even Tinder, heralded as more of a game than an actual dating service by many Millennials, will soon start charging for a premium edition to get a bigger piece of the online market.
People once looked down on online dating, but now it is widely accepted and continues to grow in popularity as new mobile devices provide additional platforms.
One in 10 Americans has used an online dating site or app, according to a report from the Pew Research Center, and 59 percent think they're a good way to meet people. So how do these companies keep their products running to find you love? Mike Maxim, chief technology officer at OkCupidsays the company is always making minor improvements to its algorithm to make the service better.
In their algorithm that matches users with one another they use match percentageswhich basically quantifies how much users have in common, along with their popularity and in-box messages.
On any dating site, he says, a small subset of users will receive the majority of the messages. The popularity metric which isn't displayed on people's profiles helps them match people with similar status on the site.
Misbehaving users are a continuous battle, Maxim says, especially on a free site like OkCupid.
