Singapore govt dating app uses Gale-Shapley stable marriage algorithm (twitter.com)
purplepatrick 36 minutes ago
This is a common problem with all dating apps. Specifically, interests, hobbies, daily routines, objectives, etc. have nothing to do with compatibility.
“We like the same things!” is the compatibility signal of a naive 22-yr old…

On the other hand, actually applying a 'stable marriage algorithm' to people makes a bunch of assumptions which are worth interrogating:
- Do people actually know what they want even in the short term?
- Do people's preference change meaningfully over longer periods of time?
- Does your preference _upon reading people's profiles_ have any strong relationship to your preference after spending any amount of time with them?
The property that right after being matched, no one could have matched with someone whose profile they preferred more does not mean that this will create stable relationships.

The thought experiment I usually pose is to ask what you think a free, open source, and community supported dating app would change. The answer is "not much".

I would like to create a service that opperated like OkCupid used to before they sold out. Visible compatibility percentages and being able to search profiles. No curation/algorithms or swiping.
I'm interested in helping people, not taking their money.

While that certainly sounds difficult, it sounds feasible for e.g. Facebook.

That sounds more like a framing problem. If the ultimate goal is promoting long-lasting new romantic relationships, and it's developed without any profit motive, I'd imagine a general social network that primarily organizes in-person social gatherings.

Yes, the FOMOism in dating app user psychology is extremely real, but this isn't a product problem, it's a human psychology problem. In theory, you could make an app with, say, a lifetime number of swipes to prevent infinite FOMOism, but it would fail to be a viable product model because the #1 thing that I found users wanted -- more than everything else -- was optionality. And if you don't offer it, they'll go to someone who does.
Hinge actually already uses Gale-Shapley and it doesn't seem to be producing meaningfully improved outcomes.

Model a world where everybody's self-perception of their mating value is just a little bit higher than their actual value - in other words, one not too far off from reality. Some segment of this population will drop their standards in the face of repeated rejection, and then eventually find a partner because of this. Their "lowered standards" become an accurate self-perception of reality. But some segment of the population will be unwilling to do this. They have a problem - they cannot find a partner no matter how hard they look.
A problem creates a market. People who can't find a partner turn to dating apps to find a partner - some may pay, and a lot more will click on ads. There's a decent chance that dating app management isn't consciously optimizing for failure in dating and success in clicking on ads. However, all the apps that are good at finding partners for their customers find that their customers disappear, while the apps that are good at getting people to click on ads generate huge amounts of revenue and take over the market. Which is entirely composed of people who don't actually want to find a partner, anyway, because those people who care more about the outcome of finding a partner will usually drop their standards enough to find one.
The same dynamic applies in many other markets. Evolution and selection bias > intent and intelligent design. The market ends up composed of people who can't achieve the ostensible purpose of the market, largely through their own actions, because people who can drop out of the market. Happy people often go through life with very few transactions: they might change jobs a couple times early in their career before finding a boss and job they're happy with and staying there until retirement, or they date around a little and then find a partner they marry for life, or they might rent a couple apartments before buying a house, renovating once, and then staying in it for 40 years. The transactions are overwhelmingly composed of people who are dissatisfied, because that's why they're buying things.

Which apps were these? What were your user metrics?
Seems somewhat suspect to extrapolate from your personal experience to what the large dating apps are allegedly doing if you are not approaching their scale. You've mentioned your personal experience as some kind of authority a few times now in this discussion, why not name the two apps directly? Apologies if I missed it but I don't see where you gave any indication that this appeal to authority is credible.

You’re never going to match with people who aren’t actively looking.
You’re only ever going to match with the people who are looking at the same time as you.
Your criticisms are true of real life without apps. That’s why we have this thing called “divorce”.
Comments like these always seem to miss the point. They aren’t trying to solve marriage. They are trying to create social lubricants to get young people more interested in dating. This algorithm tries to ensure that at the very least your core values at the time match up.

The productive question would be to figure out how far outside someone's preferences they can go while still settling happily.
miki123211 2 hours ago
At least, you should have some algorithm estimating marriage length / likelihood of divorce based on your (non-app) statistics, and then use that as one factor for your in-app calculations.

Imagine A ranks X,Y,Z in that order B ranks Y,X,Z in that order C ranks X,Y,Z
X, Y, Z rank A,B,C in that order.
A will propose to X and match. B will propose to Y and match. C will propose to X and get rejected. C will propose to Y and get rejected. C will propose to Z and match.
Y will never get a proposal from A. Z will never get a proposal from A or B.

Maybe 4 participants is too few to clearly see what happens.
computably an hour ago
The minimal example with 4 participants is if each person P has unique preferences and P's 1st choice has P as 2nd choice. So in this case just flip X:
A:XY B:YX X:BA Y:AB
If A,B propose you get AX,BY. If X,Y propose you get BX,AY. Both are stable because the proposers are getting their first choice.

- proposers descend from their 1st choice, while recipients ascend according to their offers; the outcome can't be recipient-biased, because recipients ascend only when proposers are forced to descend
- a matching is stable if each pair contains at least one party that cannot find a strictly better match
- in particular there are multiple distinct matchings, and if proposer-biased, recipients have no recourse to break the proposer-favored pairs

The dating market is similarly full of people who would like to clear transactions (economist speak for form a relationship), yet cannot because they do not meet the reserve price of those they want to date.
I hope my Ferrari analogy helps to illustrate the core concept, but you have realize that dating markets are even tougher than car markets, because dating is a barter market. For a transaction to clear, there needs to be a double coincidence of wants -- you can't simply use a medium of exchange like dollars to cut the transaction in half. Imagine if to buy a Ferrari you had to find a seller who also happened to need $350k worth of Linux sysadmin work done.

More specifically, they would rather be single than pair with any of the options that are realistically available to them. Hence, the market fails to clear.

In past the motive for marriage was sex and companionship which was frowned in society if out of wedlock. Now it is not frowned upon. The old constraint is gone and we need to add new constraints if we want to solve the problem.

As a secondary problem, people (traditionally women, but with a two-income household it could be either party) often already can't leave a relationship because they can't support themselves and their child(ren) without the other half and so they're stuck in relationships that might either not work for them or that are downright abusive. With a big tax on leaving your partner... oof, why in the world would you want more lock-in?! Is this a manosphere thing that I'm not aware of?

It certainly doesn't help that the app conveniently targets those between 21 to 35 years of age, which is just before advanced maternal age (also the age where single Singaporeans qualify for public housing).

China is a cultural and diaspora behemoth. Completely apples to oranges comparison.
What about countries similar to Singapore's size and wealth? An interesting thing to look at: how many US electeds are Singapore, Israel, Hong Kong or Taiwan 1st-generation heritage or born? I like this number because you cannot fake it (unlike so many things, like statistics reported by countries that are not free), you cannot buy an election or run a PR campaign to pretend you had a successful election, and it measures a real notion of power (something the CCP aspires to have): Singapore 0, China 9, Taiwan 11, Hong Kong 4, Israel 7.
Anyway I don't really buy into this line of thinking but it is interesting to me to look at a place that isn't really free, like Singapore, and figure out how it affects me.

While many countries in the west have a two or multi party system due to historical reasons, on certain issues they often just function as controlled opposition, making your vote worthless anyway, with political battles between parties now being mostly and ideological circus to keep the unwashed masses distracted and divided while they get robbed blind, rather than focused on actually fixing things for the working class.
If Singapore can skip this expensive time consuming circus and just get shit done, then good for them, but I don't want our western leaders to take the wrong lesson and move us to a dictatorship as the promised solution to fix things, which is what I feel they're trying.

Private ones will always prioritize profit which means they want you to keep using the app which means they don’t want you to find a partner.
Modern dating apps makes it so that an average woman will have unlimited choices but the average man will have next to none. Before dating apps, they could have been a good match. But with dating apps, the woman has unlimited higher value men. How could these average women marry an average man if she’s being taken on dates constantly by top 5% men?
The problem is that these higher value men will not commit because they also have unlimited options.
Even if she marries an average man later in life, she will feel resentment towards him. Therefore, these women just choose to stay single. This is especially viable now because women often are more educated and have good income.
Now we can see why young men are increasingly becoming far right and longing for far more conservative world.
Modern dating apps are just manifesting natural instincts on steroids. I don’t blame either party. Just an observation.

Further, customer psychology doesn't tend to reward paying to improve a bad experience. Users are more like to pay to upgrade an already good experience.
There is a very common idea that there is some conspiracy on dating apps to prevent coupling up as some strategy to reduce subscription churn, but it really just isn't true. The market is plenty large enough. Millions of relationships end every day. Millions of people turn 18 every day and enter the (online) dating world. The cold hard truth is that almost every complaint about the online dating experience is a complaint about human behavior, not about something remediable with better product design.

Because most countries aren't actually trying anything nor can the government do much in that regard when the issues are cultural and emotional.
The low-birthrate couples who can't/don't want kids aren't suddenly gonna want them if you give them 3 months of paid maternity leave and a monthly stipend or other such welfare perks.
And those who do have kids because of government welfare perks, were having kids anyway, they're now incentivized to have even more.

The countries that do try seem to fall short of actually replacing even a few years of serious career work and offer no way to go back to that career after taking care of children for a while, so you just need to do that.

Unironically Mao/Nixon and Henry Kissenger almost put us into a hilarious world where we (the USA) would have "imported" ~10 million Chinese women. Mao unironically proposed this and his argument about why it would have hurt us is that they "have too many children!":
"Chairman Mao: (Laughing) Those are honest words.
Dr. Kissinger: This is our position.
Chairman Mao: Do you want our Chinese women? We can give you ten million. (Laughter, particularly among the women.)
Dr. Kissinger: The Chairman is improving his offer.
Chairman Mao: By doing so we can let them flood your country with disaster and therefore impair your interests. In our country we have too many women, and they have a way of doing things. They give birth to children and our children are too many. (Laughter)
[Page 132] Dr. Kissinger: It is such a novel proposition, we will have to study it."
