Once you’ve filled out a profile, online dating sites will provide a list of matches -- people they think you are compatible with. The more matching attributes that two profiles have, the higher “match percentage” the site will assign to it. Each profile has a list of attributes or interests that members check off.
Neil Clark Warren, who studied thousands of marriages to develop his “predictive model of compatibility.” Do such scientific methods work? However, scientific personality tests completed with the guidance of a trained researcher do not have 100 percent accuracy (it’s closer to 75 percent).
And when you’re sitting alone in your living room filling out a personality profile on a Web site, there is an even greater chance that the resulting matches will not be perfect.
When you multiply the chance for inaccuracy by the number of users on a given dating site, complicated matching systems are probably not working much better than basic attribute-and-interest matching.
Fortunately, the main advantage of online dating is that it gives each user control over who they contact and with whom they subsequently communicate.
It might take more work than relying on the site's matching system, but browsing through profiles yourself may ultimately be the best way to find the right person.
Specific facts and figures for online dating are hard to come by.
