Online dating has become the most common way for couples to meet in the United States Rosenfeld et al. Fifty-two percent of Americans who have never been married say they have tried their luck with online dating Anderson et al. There is also evidence that online dating may be changing the composition of real-world relationships. According to a study by Cacioppo et al.
Outside of the United States, millions of people use online dating services Maybin et al. Online dating generally progresses through a series of stages that involve filling out a profile, matching, messaging, and, if all goes well, meeting in person. Although success can mean different things depending on the person, meeting face-to-face be it for casual sex or for a committed relationship is generally a good indicator that a platform has done its job Ellison et al.
The problem for data science is finding the best way to filter and sort at the matching stage in order to make recommendations that will lead to successful outcomes. Most online dating platforms do this by relying on algorithms and artificial intelligence AI to introduce users to partners with whom they might be compatible. But can matching algorithms learn to predict what has long eluded their human creators: the secret to romantic compatibility? The following sections explore this question by tracing the history of online dating from desktop computers to smartphones and the emergence of modern methods for finding romance with data.
One of the first commercial forays into computerized dating took place at Harvard University in Mathews, , but it would be decades before online dating would go mainstream with the arrival of Match in the mids. Early online dating sites bore a strong resemblance to newspaper personal ads and were designed for users to click through profiles until they found someone who piqued their interest.
The appeal of these sites was that they afforded greater access to potential partners, yet too many options can be overwhelming and leave people feeling dissatisfied with their decisions Finkel et al. In a classic example of choice overload, Iyengar and Lepper presented grocery store shoppers with a tasting booth containing either six or 24 flavors of gourmet jam. Despite being drawn to the booth with more options, shoppers were the most likely to make a purchase when given fewer choices.
Online dating sites began to experiment with compatibility matching in the early s as a way to address the issue of choice overload by narrowing the dating pool. Matching algorithms also allowed sites to accomplish other goals, such as being able to charge higher fees for their services and enhancing user engagement and satisfaction Jung et al.
Some sites even went so far as to eliminate the ability to search entirely, which meant that users had fewer options but also less competition since there were not as many profiles to choose from Halaburda et al. In , eHarmony was among the first online dating sites to develop and patent a matching algorithm for pairing users with compatible partners. Neil Clark Warren, and guided by research they conducted with 5, married couples Tierney, As part of the sign-up process, users completed a compatibility test that included as many as questions about themselves and their preferences for an ideal partner eHarmony, Of course, this does not eliminate the possibility that, algorithm aside, the eHarmony couples may have been more motivated for their relationships to succeed in the first place Houran et al.
Not long after, in , OkCupid began offering algorithmic matching alongside the basic search functionality that users had come to expect from earlier sites. The combination of searching and matching on OkCupid meant the algorithm functioned as more of a decision aid by empowering users to seek out potential partners for themselves while also offering suggestions to narrow the field Tong et al.
The data came from an assortment of questions e. The problem with these early matching systems is that they assumed users knew precisely what they desired in a partner. This is further complicated by the fact that online dating often encourages users to prioritize qualities e. The release of the iPhone in and subsequent launch of Grindr in marked a seismic shift in the industry from online dating sites to mobile dating apps. Collaborative filtering algorithms work by delivering recommendations based on the behaviors of users who appear to have similar tastes Krzywicki et al.
For example, imagine a hypothetical scenario where Tyrone is attracted to Carlos. If others who like Carlos also show an interest in Zach, then Zach will be presented to Tyrone as a possible match. This strategy is used to suggest products on Amazon and movies on Netflix, but on dating apps, recommendations must be reciprocal to minimize rejection Pizzato et al.
In other words, matching algorithms must consider not only whether one person is likely to find another attractive but also whether that interest will be well received. Like other games of skill, Tinder uses the Elo system Elo, to rate the desirability of users and match them with others who are in roughly the same league Carr, Tinder claims to have retired Elo scores but provides few details about its new system Tinder, Also in , Hinge was founded as a dating app geared toward long-term relationships.
The Gale-Shapley algorithm solves the problem of creating stable matches between two groups when both sides prefer some partners over others e. For instance, by matching Ravi with Ava, one can be confident that there is no one else in the dating pool they would prefer who would also be interested in them in return. Lloyd Shapley and Alvin Roth won the Nobel Memorial Prize in Economic Science for their work with the Gale-Shapley algorithm, which is in many ways a natural fit for online dating.
One concern about the use of collaborative filtering for matchmaking is the potential for gender and racial bias to creep into the algorithms Hutson et al. MonsterMatch is a dating app simulation that illustrates how this might happen and the ways collaborative filtering algorithms can exclude certain groups of users by privileging the behaviors of the majority.
Given these concerns, MonsterMatch co-creator Ben Berman has urged dating app developers to provide users with the option to reset the algorithm by deleting their swipe history or to opt out of algorithmic matching entirely Pardes, It can be difficult to say with any certainty since most matching algorithms are proprietary, but scientists are skeptical of their ability to predict long-term relationship success Finkel et al.
In a study, Joel et al. built a machine learning algorithm to attempt to predict romantic desire using constructs from relationship science. As Finkel et al. One thing that is becoming clear is that matching algorithms may not need to work for online dating to be effective. In a blog post for OkTrends, Rudder described a series of experiments where bad matches were led to believe that they were good and good matches were lied to and told that they were not compatible i.
Matching algorithms have come a long way from the online dating sites of the early s to the dating apps of today and continue to grow increasingly complex. Looking to the future, a report by eHarmony projects that the next few decades could see algorithms integrated with DNA data and the Internet of Things in order to deliver more personalized recommendations Deli et al.
Beyond matchmaking, algorithms will be key to creating safer and more equitable online dating experiences. For example, Bumble, which has been labeled a feminist dating app thanks to innovative design features that challenge pre-existing gender norms, has begun using AI to respond to harassment directed at women on the platform Bumble, These advances make it important to consider how algorithms could affect the long journey of evolution of online dating by bringing about major changes in the coming years.

This captured how choosy each person was. Did they click with a lot of people or did they find it hard to feel chemistry? By comparing daters to each other on choosiness the researchers could control for people who might make a lot of potential connections mostly because they were quite open-minded about who they would like to date.
Second is partner desire, or, how much did people like you compared to their other dates. The reverse of actor desire, this is a measure of average attractiveness. They are not saying they will filter your pool so you only have attractive people to choose from. Joel found that her algorithm could predict actor desire and partner desire, but not compatibility.
Not even a little bit. This might sound like a bit of a head scratcher, but, Joel says that her algorithm would have been better off using mean results for every dater rather than offering a tailored response.
My rating of whether I found you funny after meeting you will predict whether I like you, but my desire for a funny person and your measure of whether you are funny do not because we might not agree on a sense of humour. Another team of researchers seem to have successfully predicted romantic desire using an algorithm.
Picture a house filled with potential dates. The higher up in the house someone is, the kinder they are. The further towards the back, the funnier. The further to the right, the more physically attractive, and so on until you have collected data on 23 different preferences. Now, depending on your preferences, you can imagine your perfect partner is standing somewhere near the bathroom sink, for example. There might be other people nearby, who would be nearly as attractive.
There might be someone even funnier and more beautiful than them, but a little less kind, stood in another room downstairs. That is how Dr Daniel Conroy-Beam, an assistant professor from the University of California Santa Barbara, US, describes the algorithm. The distance between a potential partner and your idealised partner in your hypothetical house was the best predictor for attraction.
In this particular study the daters were presented with fake profiles of made-up people, not real potential dates. Although, Conroy-Beam points out, people judge online profiles before they have a chance to meet or even talk to their potential dates, so you could consider online profiles hypothetical, up to a point.
If physical attraction matters much more to you than kindness then perhaps that person waiting downstairs is a better candidate after all. Clearly, having a list of preferences makes things complicated. In what order do you rank them? Are your assessments of your qualities the same as mine? All of this makes predicting romantic interest difficult. Perhaps a more straightforward option is to look at deal-breakers — what would rule someone out for you?
After whittling their choices down to a favourite, the researchers offered to swap their contact details. However, at the same time they were shown a bit more information about their chosen partner, which included the fact that they had two deal-breaker qualities. They were prepared to overlook them. It turns out, when presented with an opportunity to meet someone who is supposed to be interested in us, we are much more flexible about who we are interested in.
We hardly broadcast our less desirable qualities at the first opportunity. Often deal-breakers only show up after the first date — so how are you supposed to know is someone is a turn-off unless you meet them? Why might we not strictly observe our deal-breakers? People feel like they need to be choosy because that is our culture.
But realistically people are pretty open to a broad range of partners. At one end of the online dating spectrum are sites like Match. com and eHarmony who, as part of the registration process, ask users to complete reasonably extensive questionnaires. These sites hope to reduce the amount of sorting the user needs to do by collecting data and filtering their best options.
We start with questions, although these have changed and been refined over time based on machine learning. Then, marriage was much more important. This shift has reflected the slight change in attitudes over the past two decades. As our algorithm demonstrates, kindness is still really important.
More than being highly sexualised — that tends to not work so well. The data also suggests that being very, very attractive as a man offers no advantages over being fairly average. Women like men who rate themselves as five out of 10 as much as men who think they are 10 out of 10s, whereas men would ideally date someone who self-rates their physical appearance as eight out of At the other end of the spectrum, apps like Tinder and Bumble ask for very little in the way of preferences before they start to show you profiles: usually, the gender of the person you are interested in, an age range and distance from where you live.
I might not have a lot of insight into what I find attractive and what I am actually like.
It's the middle of peak season for the online dating industry. As the calendar inches closer to Valentine's Day, I know that you have many choices with the thousands of online dating sites that have popped up in recent years. Perhaps you'll select one that you've viewed on television showing the happy success couples.
Maybe your cousin's engaged to a guy she met online and you select that site to dip a digital toe in. But do you ever wonder what happens behind the scenes at the online dating sites? Did you know you could find a date or a mate based on medical issues, pets or ethnicity?
Did you ever wonder why you were being asked so many questions while setting up your profile? These questions create the dating algorithms that some believe will increase your chances of finding a better match. At the recent Internet Dating Conference iDate in Las Vegas, I had the chance to speak with writer Dan Slater about his new book, Love in the Time of Algorithms. As an online dating executive, I've read the book from cover-to-cover before interviewing Slater.
Here's his insight to the online dating industry. A: It certainly wasn't one thing, and I wasn't dying to write this book my entire life. Around the time that I lost my job at the Wall Street Journal , I also become single at the age of I started using online dating sites for the first time and saw how different the process was. A year later, I found out my parents met through a computer dating service in the '60s.
I went to iDate in to learn about the business and wrote an article in GQ , which became a launching pad for the book idea. Q: In The Atlantic article, " A Million First Dates ," you take the position that online dating threatens monogamy. Do you believe that people don't want to connect long-term or that they just don't want to get married?
A: The Atlantic article was an excerpt of the book. The article framed monogamy in a way that made the meaning different from what the meaning was in the book itself.
As far as the demise of monogamy, that was not the point I was making. I think monogamy and commitment are two different terms. Monogamy is about loyalty; about fidelity to the person you are with. Commitment, in my mind, defines the level of engagement in a relationship and the speed that someone moves through relationships.
People who are in relationships, which aren't fantastic, might have stayed together before. I think the new availability of meeting new people though online dating makes it easier to leave a relationship and find someone better. Q: Do you think the dating algorithms help to create better matches and better relationships?
A: I'm somewhere in between where the academics of the world say [on one hand] and eHarmony [on the other hand]. I don't believe a computer can predict long-term compatibility or long-term relationship success.
If you interview online daters, you'll find many who are unhappy with the technology, but will find others who think it's kind of amazing. Online dating is getting better at predicting who would get along on a first date. As the technology evolves, it's a good chance that it will get even better.
Q: In your book, you referenced the U. census statistic that 39 percent believe marriage will become obsolete. Do you agree? A: No. I don't think that marriage will become obsolete. I think that's absurd. You don't stomp out a business model. People who are in successful marriages will tell you that marriage is one of the best things that has ever happened in their lives. A: It's hard to say. It would depend on what age I was and what period and time it would have happened.
I would be influenced by the media and influenced by what people I know are doing. Generally, I'd look for the size of the population and a site with a certain degree of searching capability. Q: With the announcement of Facebook's Graph Search, how do you think that will affect the traditional online dating sites? I don't think there's going to be an immediate impact on the online dating industry. In the long-term, it can be helpful, as it will further erode whatever reluctance people have to meet and date new people online.
Facebook is considered mainstream. Once people experience dating on Facebook, it sends society a huge message that any stigma attached to this is now gone.
That's how it could help the online dating industry. One of the ways that big sites make money is by having anonymous profiles. If people come to expect non-anonymity in dating, then what happens to those paid sites? To me, that's a pretty interesting question, but that's a way off. I think it's very challenging to be forming relationships these days, especially online with Facebook around. In the old days, you'd meet someone, whether online or offline, and you'd gradually meet during phone calls and face-to-face meetings.
Now you go home and friend each other on Facebook and you're suddenly exposed to all of this information on Google, Facebook and Linkedin. You don't know them, but you have all of this information.
It's hard to form the trust you need when you can see each other's lives play out online. There's a big disconnect between what you think you know and what you actually know.
Q: Do you believe that singles can find love with mobile dating apps or will they remain predominantly for hook-ups? I think mobile has a long way to go in terms of societal acceptance.
It's such a radical departure from what online daters are used to. If you look at the history of online dating over the first 10 to 15 years, it's developed in terms of more efficiency. What does mobile dating do? It's just one more step towards efficiency.
My hunch is one day it will be the norm, once people learn to use it in a way that's more satisfying to them and not threatening. A: I'm a journalist and was a lawyer for a brief period of time. I want to write. I loved immersing myself in this subject for the two-plus years that I did. It was a fascinating subject to explore. I don't think I have much more to say. I will now be a lifetime follower of the industry and who the players are as well.
