"It is very very difficult, if not impossible, to predict initial chemistry using variables assessed before two people meet each other," said study co-author Paul Eastwick, an assistant professor at the University of Texas at Austin."The algorithms are not scientifically valid and are extremely unlikely to generate compatible matches." In other words, matchmaking sites simply can't account for how two people will get along in person — chemistry, if you will.In order to do so, they both engaged in researching just what made someone desirable online through a combination of coding, A/B testing and statistical probability.Part of OKCupid’s appeal is in the compatibility matching.The lower your compatibility with an individual, the less likely you were to show up in their searches.Mc Kinlay, frustrated that he had such low compatibility with women in the Los Angeles area, used bots to gather information on how women answered questions and sorted them into discrete groups based on their interests.
"If you're at the point where you think, 'I want to share my innermost secrets with this person,' you should meet the person within three days."However, upon a face-to-face meeting, most of this list goes out the window — people instead rely on their gut-level reaction to another person." The other problem, according to the research, is the emphasis placed on clients' similarities.
