When Will You Meet "The One"?

You have more choices than ever before. That's not necessarily a good thing.

In their book Modern Romance, Aziz Ansari and Eric Klinenberg focus on how people search for a partner, a date, or a mate in a hyper-connected era when we have a seemingly endless number of options. Modern Romance is not for everyone—neither the book nor the reality it reflects. The book is written from the perspective of people who are smack in the middle of this new, unhooked, unscripted maelstrom of love, sex, and disillusionment. It captures how things are for a great number of people, which is not what many would say is ideal. The book is insightful and irreverent: Ansari is, after all, a comedian with the blunt style of those who work the clubs.

Questions around how people search for and find partners are part of an entire field of study about matching problems. There is a need to match people to jobs, schools, and mates. On a societal level, there is a benefit in maximizing the number of people who match with their best option. Individuals, of course, desire to make the best matches they can in order to increase their odds of personal happiness, fulfillment, and meaning.

You are likely familiar with a myriad of services that solve matching problems of less importance than the search for a mate. Uber, for example, matches drivers and riders. The algorithm to do this is simpler than any algorithm that would increase people’s odds of lifetime love and commitment in marriage. A 15-minute car ride is different from 60 years of riding together through life.

Ansari and Klinenberg describe the massive changes that have occurred in the past decades in how people search for mates—or dates, or just sex. In mate selection, people have gone from choosing among two or three options in their neighborhood or apartment building, to trying to comb through and cope with the awareness of a myriad of options, thanks to advances in the digital realm.

When people search too little or too much, the search for a mate is likely to fall short of leading to a good match. What strategy is just right? It’s hard to know, but the dilemmas involved lead to insights on how to have a reasonable perspective throughout the process. 

The Train Station Problem

Samantha is searching. She wants to find her soul mate. I don’t mean that she wants a mate who shares the deeper beliefs of her soul1; Samantha believes there is one perfect partner out there for her—someone who would complete her in ways far beyond being merely good, reliable, and committed. This is not an unusual goal2, but it complicates things quite a bit.

Eli Finkel and colleagues describe the changing standards that guide our search for mates:

“Throughout American history, the fundamental purpose of marriage has shifted from (a) helping spouses meet their basic economic and political needs, to (b) helping them meet their intimacy and passion needs, to (c) helping them meet their autonomy and personal-growth needs.”3 

Finkel and his coauthors argue that this expectation leads to average marriages being less happy, while a small number of marriages that can satisfy the expectations for personal fulfillment may be happier than the “best marriages in earlier eras.”

Samantha wants that.  

She is acutely aware of her dilemma. She has no foolproof way of knowing where to find “the one” or how to know for sure who is “the one” when she meets him. Metaphorically, Samantha is in a train station trying to figure out which train to get on, and stay on, for the ride of her life.

Samantha has checked out five trains. Those “checks” range from having a brief coffee with one guy she met online, to being deeply involved with a guy she dated for 16 months before eventually deciding he was not the one. That’s a long train ride, and it left Samantha further down the tracks and at another station. Now she’s worried that she might have missed her best option during those 16 months. Serious involvement often has opportunity costs. Still, she is a believing person, and she takes comfort in a belief that God will not allow her to miss the right train. Still, this belief in destiny is balanced by her sense that the odds are decreasing as time marches on.

Samantha wonders if the perfect train has yet to appear at her station or if she’s missed it already. Her fear of missing the best train is palpable and even paralyzing: “What if I make the wrong choice?” “Am I even on the right rail line?” “How long do I stay on one train before I get off if I am not sure it’s the one?” “What if I leave one train and then, later, realize it was the best train for me?” A lot of the time Samantha feels like curling up on a bench and just letting all the trains roll through the station.  

Heuristics for Matching

Psychologists Peter Todd and Geoffrey Miller wrote about mate searching in a respected volume on simple heuristics for making the best decisions under various conditions of uncertainty4. A heuristic is a mental shortcut that simplifies decision-making in order to achieve what is often a good-enough solution when the costs of further time and effort are unlikely to be worth the gain.

Todd and Miller describe some of the history of attempts to come up with the best heuristic to solve searching and matching problems in mate selection. They get to the heart of Samantha’s anxiety—the “uncertainty that the next prospect that one encounters might be far superior to the best seen so far.”5 She fears that once she makes a choice, the next train into the station could be the best one for her.

Todd and Miller note that if you could know in advance the number of options you’d get to consider in choosing a mate, you could use a guideline that a number of studies suggest yields the highest likelihood of the best outcome. The rule is to select the best option that appears after you have considered 37 percent of the options. You can see why knowing the total number is important here, because otherwise, you’d have no way to even guess when you’ll hit that 37 percent point. Todd and Miller explain some of the arcane history of this decision rule, and they do a particularly nice job describing the necessary assumptions for such heuristics to work.

Suppose Sam is going to have 10 trains to consider in her life. By this rule, she should check out the first four—but not choose any of them. Those poor guys don’t even know that they have no chance: Sam is tough and she’s working the rule. But starting with Number 5, Sam is ready to pick the first one that is better than any of the four she’s seen so far. If the best option of all was in that first four, that’s pretty sad—this may be why people intuitively favor monitoring past partners through social media. It’s become easy to do, and some people clearly believe that it increases their odds of calling a train (if it’s not occupied) back to the station.  

Let’s suppose for a moment that the 37 percent rule is pretty good for selecting a mate. (I personally prefer a strategy that’s a bit broader.) As Ansari and Klinenberg state, part of the problem for today’s young adults is that they are trying to cope with an awareness of a truly countless number of potential partners. While that's not actually true, a young adult today might think that the 37 percent rule still means checking out hundreds or thousands of potential mates. That’s going to take some time, even in Grand Central Station.  

Let’s bring sex into the equation. If a person believes that he or she needs to check out a lot of partners, including testing for sexual compatibility, that’s going to add up to a lot of sexual partners before settling down in marriage. That strategy has numerous risks, which I will not enumerate here. Galena Rhoades and I find that the median number of sexual partners emerging adults have before settling on a mate is around five or six, and that having sex with others in addition to the person one marries is associated—although, modestly—with lower marital quality6

Todd and Miller don’t leave us at the 37 percent rule. They note that, even where all the assumptions are met, it only leads to the best solution 37 percent of the time. Their main focus is to make a mathematical case for satisficing, or accepting an option that meets a reasonable level of expectation7. For example, Todd and Miller argue that a 14 percent search rule (instead of 37 percent) gets 83 percent of people to the top 10 percent of their options. Contrast that with the people seeking absolute perfection, who may end up searching so long that they leave behind better options before finally settling on the last train to Clarksville.

The Misery of Searching for Perfection

As Todd and Miller describe, Frey and Eichenberger (1996) argue that people do not search adequately for a mate8. Distinguished sociologist Norval Glenn also made this point in a chapter published in 20029. There are many causes of poor searches. One of Glenn’s growing concerns was how “premature entanglement” was common and could foreclose an adequate search for good matches. Norval and I had a wonderful talk about these ideas over dinner in 2000. This was just after I had started thinking a lot about the inertia problem with cohabitation. We both thought that a lot of people were increasing their odds of taking the wrong train when they did not have to do so. Thus, while there is increased freedom of choice and a growing availability of tools for searching, these factors may be offset by the growing trend toward sliding through relationship transitions in ways that lead to giving up options before making a choice10.

You don’t have to stay on a train for miles and miles to get a good sense of it. Many people do, however, owing to the ease of entry into cohabitation. People slide into cohabiting11, which rapidly escalates inertia in the form of constraints; these constraints make it more likely one will stay in a relationship regardless of their level of dedication to it12. Of course, many other people forego serious romantic involvement altogether, being somewhat paralyzed by the fear of making the wrong choice. Why would that be? While there are more tools than ever before that could be employed to search for good matches, the expectations for marriage are also higher than ever. The increasing availability of tools for searching might increase fears of failing to find perfection; the quest may now appear both more possible and impossible as the same time.

Despite concerns in the late 1990s about inadequate search, I believe the changes Ansari and Klinenberg document are real, and that in just the past 15 years, people may have started to err in the direction of searching endlessly rather than searching too little. Of course, an endless search for the perfect mate is also, in a very real way, inadequate.

As noted in a prior, briefer post, Ansari and Klinenberg call attention to the work of psychologist Barry Schwartz (The Paradox of Choice), who has written about the dilemmas of having too many options. This argument by Schwartz recounted by Ansari and Klinenberg is brilliant:

By Schwartz’s logic, we are probably looking for “the best” and, in fact, we are looking for our soul mates too. Is this possible to find? “How many people do you need to see before you know you’ve found the best?” Schwartz asked. “The answer is every damn person there is. How else do you know it’s the best? If you’re looking for the best, this is a recipe for complete misery.”  

That’s a whole lot of train tickets. Schwartz points out that the very belief that you can find the perfect match at the end of a search sets you up to think there must always be something better—an option that you’d not seen or found yet—and this makes people less happy with what they eventually choose.

Commitment is making a choice to give up other choices. That’s the deal. Believing that you might have found perfection elsewhere—if you’d only searched a little more—will make it harder to commit to, invest in, and be happy with the person you married.
