Patagonia say it's owned by the Earth now. However, I wanted to do a deep dive into the science of the algorithm — what drives this fast-growing matchmaking process?
Online dating is algorithmic matchmaking. Most apps ask you a series of questions or require you to list preferences, the answers of which are assessed by an algorithm and used to pair you to potential partners. There are a host of issues that can accompany use such as safety, objectification, superficiality, etc.
but there are also benefits. Love has patterns, and these algorithms take advantage of those patterns to recommend compatible partners across the network. The number of users is expected to grow by 5M, up to Match Group, the online dating conglomerate, owns Hinge, Tinder, Match. com, OkCupid, PlentyofFish, and many more. The apps seem to be doing well. Most of them rely on a freemium model, in which the core features of the app are free, but premium features are offered on either a subscription or a one-time purchase basis.
The pandemic has driven a lot of users to the apps, as the more traditional way of meeting someone the bars, the gyms, etc. are closed down. Hinge was launched in and has grown to be a popular app for the relationship-minded, particularly among the millennial and younger generation… Hinge is a mobile-only experience and employs a freemium model.
Hinge focuses on users with a higher level of intent to enter into a relationship and its product is designed to reinforce that approach. From a user perspective, Hinge is kind of like Tinder, but less aggressive.
You answer 3 questions of your choice that others see, and upload 6 pictures of yourself, like above. It measures this based off your engagement and who engages with you, as well as matches you to people with similar preferences. The dating market is two-sided: one person seeks out another, with the platform serving to enable interaction. It broadly relies on network effects: the larger the pool the app the pulls from, the higher probability of finding a person that meets preferences.
More specifically:. Given n men and n women, where each person has ranked all members of the opposite sex in order of preference, marry the men and women together such that there are no two people of opposite sex who would both rather have each other than their current partners. When there are no such pairs of people, the set of marriages is deemed stable.
Source: Wiki. The Gale-Shapley algorithm solves this through a series of iterations in which element A proposes to their highest ranked element B. The matching is considered stable when there is no match A, B that prefer each other over their current partners.
We need to match the bug to a tree, through stable pairings. So we have four bugs: a bumblebee, a ladybug, a caterpillar, and a butterfly. We also have four trees: a pinetree, a cactus, a tulip, and an oak tree.
The bumblebee prefers the pinetree, the ladybug prefers the oak tree, caterpillar likes the cactus the most, and the butterfly likes the tulip. The butterfly would be happier with the tulip, but because the tulip is with the caterpillar which it prefers over the butterfly the matching is stable.
As human communications expert Liesel Sharabi explains, the algorithms underlying the matchmaking have evolved enormously in complexity over recent years, and our relationship with online dating apps have become a long-term prospect. Keywords: algorithms, machine learning, matchmaking, online dating, recommender systems.
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.
