Secondly, I don’t make any judgement about the validity of the ‘dating rule’ – you might find it a useful rule of thumb or a ludicrous restriction; I find it a nice thing to do some algebra on. There is a so-called rule about dating: the youngest age you are supposed to date is half your age plus seven.

Why would we want to do this? Well, it means we can work out some other implications of the rule.

There’s a reason why this is also called the 37 Percent Rule. The best strategy for dating, according to math, is to reject the first 37 percent of.

The Half Plus Seven Rule is an unwritten rule that asserts that it is creepy to date anyone who is younger than half your age plus 7 years.

As the graph shows, there is a lower limit and an upper limit. As age increases, the age range of potential non-creepy partners widens. At 26, the range of non-creepy partners is 18 years to year-olds.

A common rule of thumb, at least on the internet, is that it’s okay to be interested in someone “half your age plus seven” years. According to this.

In this era of the Internet, meeting new people is much easier than before, but paradoxically, finding the proper partner is still a challenge.

I am trying to prove the theoretical “percent rule” for dating. The setup, if I remember correctly, is this. The potential mates rank from best to worst in a total ordering , and you want to maximize the probability that you end up with the best one.

However, you can only tell how good the mates are relative to each other , so while you can fully rank the people you’ve already met, you can’t say anything about the ones you have yet to meet. Also, for each potential mate, you can either stay with them forever or leave forever, i. The decision to marry or not need only be made when the current result is better than all previous results otherwise the current choice is definitely suboptimal. Sign up to join this community.

When it comes to love, making long-term decisions is a risky business. Sooner or later, most of us decide to leave our carefree bachelor or bachelorette days behind us and settle down. Just ask anyone who has found themselves stung by the eligible bachelor paradox. If you decided never to settle down, you could sit back at the end of your life and list everyone you ever dated, with the luxury of being able to score each one on how good they could have been as your life partner.

Such a list would be pretty pointless by then, but if only you could have it earlier, it would make choosing a life partner a fair sight easier. But the big question is, how can you select the best person on your imaginary list to settle down with, without knowing any of the information that lies ahead of you?

As they say, there are plenty of fish in the sea. And as mathematicians will tell you, the more fish you kiss, the better your chances of finding a catch. Sea life analogies aside, Dominik Czernia, a physics Ph. Although the underlying principle isn’t quite as romantic—the ” Optimal Stopping Problem ,” as it’s called, basically asks you to reject your first two of every five dates—Czernia has managed to make the art of love as close to a science as possible, with some spaghetti dinners required.

You don’t know the value of the offers before they come. With each offer, you must decide whether you accept or reject it. How long should you wait for the best deal? Such is the case in the hunt for the perfect partner, he says. If you go on dates with different people—and Czernia is careful to note that, of course, the actual number of dates will vary by person—it’s difficult to know which of the people you should choose to date.

## A mathematical theory says the perfect age to get married is 26 — here’s why

More recently, a plethora of market-minded dating books are coaching singles on how to seal a romantic deal, and dating apps, which have rapidly become the mode du jour for single people to meet each other, make sex and romance even more like shopping. The idea that a population of single people can be analyzed like a market might be useful to some extent to sociologists or economists, but the widespread adoption of it by single people themselves can result in a warped outlook on love.

M oira Weigel , the author of Labor of Love: The Invention of Dating , argues that dating as we know it—single people going out together to restaurants, bars, movies, and other commercial or semicommercial spaces—came about in the late 19th century. What dating does is it takes that process out of the home, out of supervised and mostly noncommercial spaces, to movie theaters and dance halls. The application of the supply-and-demand concept, Weigel said, may have come into the picture in the late 19th century, when American cities were exploding in population.

According to this rule, the age of the younger person should not be less than half the age of the older person plus seven years, so that for example no one older than 65 should be in a relationship with anyone younger than 39 and a half, no one older than 22 should be in a relationship with anyone younger than 18, and no one under 14 years of age should be in a relationship at all From another point of view, the chart can be interpreted as saying that there should not be an age disparity of as much as five years unless the younger person has an age of 19 or more, a ten-year disparity should exist only if the younger person has an age of 24 or more, and a twenty-year disparity should occur only if the younger person has an age of 34 or more.

And people only slightly older than 14 should only be involved with those almost exactly the same age as themselves. To read the chart, go to the position along the x-axis which corresponds to your age, and the green range between the black and red lines directly above that position corresponds to the range of your partner’s ages which is deemed acceptable by the rule. The area between the blue and red lines shows where you are the older partner in the half-age-plus-seven calculation, while the area between the black and blue lines shows where you are the younger partner.
