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.

Start the conversation and keep the conversation going. Furthermore, it incorporates elements of their former Elo rating system, where your ranking increased based on how many people swiped right on you, and the more right swipes that person had, the more it meant for your score.

This website is produced by BBC Global News, a commercial company owned by the BBC and just the BBC. No money from the licence fee was used to create this website. In one night, Matt Taylor finished Tinder. He ran a script on his computer that automatically swiped right on every profile that fell within his preferences. Nine of those people matched with him, and one of those matches, Cherie, agreed to go on a date.
Fortunately Cherie found this story endearing and now they are both happily married. If there is a more efficient use of a dating app, I do not know it. Taylor clearly did not want to leave anything to chance. Why trust the algorithm to present the right profiles when you can swipe right on everyone? No one will be able to repeat this feat, though, as the app is more secure than it was several years ago and the algorithm has been updated to penalise those who swipe right on everyone.
Or so people believe. For those who might struggle with "packet sniffing" — the means by which Matt gamed Tinder — the tantalising promise that maybe, by putting our faith in an algorithm, an app or website might be able to find the right person is thoroughly appealing. Like most things that we wish we had, I think it deserves particular scepticism when someone claims they can do it.
Lots of apps and websites claim to be able to use data to sort through profiles for better matches. By completing their personality tests, they say they can save your thumb the effort of swiping.
The issue for scientists who might want to investigate their data, and journalists who want to fact-check their claims, is that the algorithms are the intellectual property of these companies, so they are not publicly available. Their entire business is based on developing smart match-making algorithms and keeping their formulas private.
So what do scientists do if they want to investigate predictors of attraction? They make their own. Lots of apps and websites claim to be able to use data to sort through profiles for better matches, do they work? In one example, Joel and colleagues asked people to complete a questionnaire about themselves and what they were looking for in a partner. Some of the questions were very similar to what you might expect on any dating website, and many more went way beyond.
In all, they completed more than traits and preferences. Then, after a series of four-minute-long speed dates, they were asked if they had romantic interest in any of the other daters. Now, the researchers had all three things they needed to be able to predict romantic desire. The first is actor desire, or, on average how much people liked their dates compared to others. 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. We have different sets of preferences depending on whether we are looking for something long-term or short-term, Conroy-Beam says.
Generally speaking, when were are only interested in short-term relationships we prioritise physical attraction, whereas for long-term relationships kindness and other signals that someone would be caring are a greater priority.
But, Conroy-Beam says that other preferences also imply whether we are looking for the one, and these preferences can be grouped into sets. Online dating has given us so many benefits. But it has also created a sense that we are all superficial and shallow. The important thing to stress is that this takes time. Perhaps, then, romantic desire cannot be accurately predicted before you have a chance to speak to or meet your potential partners.
We are still reliant on being able to pick up on intangible cues from talking to each other, but at least there is some evidence that good guesses can be made about who we might generally be suited to.

Racial, physical, and other types of biases sneak their way into dating apps because of that pesky collaborative filtering, as it makes assumptions based on what other people with similar interests like. 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.
