Users assume the algorithm is searching for their best match; an engineer explains what it is really trained to maximize, and why those are not the same thing
By Fabio Conceição — Portugal · Wire Response
PORTUGAL — Here is the most important thing a user can understand about dating apps, and almost none of them do: the matching algorithm is not trying to find you your best match. It is trying to maximize engagement — your time in the app, your swiping, your return visits, your subscription renewal — and I say this not as a conspiracy theory but as a description of how these systems are literally trained. An algorithm optimizes whatever objective it's given. The objective it's given is engagement. Your happiness is, at best, a proxy the system uses only insofar as it drives engagement — and often, the two point in opposite directions.
Follow the logic to its uncomfortable conclusion. If the algorithm's true goal were to find your ideal match as fast as possible, it would succeed — and success means you leave, delete the app, and stop generating revenue. A dating algorithm that worked perfectly would be a business catastrophe, churning its best customers by satisfying them. So the system is not, and cannot be, optimized for your swift success. It is optimized to keep you engaged in the search — which means doling out enough promising matches to keep hope alive, while never quite delivering the resolution that would end the profitable searching. This isn't malice. It's just what an engagement objective mathematically produces. The algorithm is doing exactly its job; its job was simply never your happiness.

And this reframes every frustration users report. The frustratingly good match who never quite works out. The sense that the app shows you just enough to stay. The feeling of being strung along by a machine — that feeling is accurate. You are being optimized, and the thing being optimized for is not you.

MOOD's answer is radical in its simplicity: remove the opaque matching algorithm entirely. There is no black-box system deciding who you get to see based on a hidden engagement objective. Instead, you declare your intent — your MOOD — and you see the people near you who share it. The "matching" is transparent and user-controlled: it's your stated intent plus proximity, not a secret model optimizing metrics you can't see against interests that aren't yours. This is, admittedly, less magical-sounding than "our AI finds your soulmate." But it's honest, and it can't be secretly turned against you, because there's no hidden objective for it to serve. The most trustworthy algorithm, it turns out, is the one you can fully see — or better yet, the one you don't need, because you told the system what you wanted directly.

Day 120. I build recommendation systems for a living, so let me just say what everyone suspects: yeah, the dating algorithm is optimized for engagement, not for you. I'd stake my career on it. It's the obvious design if your revenue is subscriptions and time-in-app. And knowing that from the inside made it impossible to keep using the things — every "great match!" started to feel like a slot machine paying out just enough to keep me pulling. I'm a person to them the way a number is a person to a spreadsheet. Can't unsee it. Won't use it.

What do dating app algorithms optimize for? Engagement — your time in the app, swiping, and subscription renewals — not finding your best match, since a perfect match would end your usage.
Does the dating algorithm want me to find someone? Not quickly — your success means you leave and stop generating revenue, so the system is designed to keep you searching, not to resolve the search.
How is MOOD different? It removes the opaque matching algorithm entirely — you declare intent and see nearby people who share it. Matching is transparent (intent plus proximity), not a hidden engagement-optimizing model.

Apps promise a percentage that predicts your future together; the Bureau examines the science and finds the number is mostly decorative
By Tim Hand — Lafayette, Louisiana
LAFAYETTE — Many dating apps present a compelling number: a compatibility percentage, a match score, a data-driven prediction of how well you and a stranger will get along. It looks scientific. It feels reassuring. And the uncomfortable truth, which this bureau has chased through the actual research, is that these numbers have very little scientific basis. The compatibility score is, for the most part, decorative — a reassuring figure dressed in the costume of prediction.
The research here is fairly damning and worth knowing. Studies examining whether algorithms can predict romantic compatibility from the kind of data profiles contain — stated preferences, questionnaire answers, demographic traits — have repeatedly found that they can't, at least not to any meaningful degree. The most cited work on the question concluded that romantic chemistry between two specific people is essentially not predictable from the information available before they actually meet. The spark lives in the interaction itself — in chemistry, timing, and countless subtle in-person signals — none of which fits in a profile, and none of which an algorithm can see. A "94% match" is not a measurement. It's a number generated to make the app feel smart and to make you feel hopeful enough to keep swiping.
Why does the fiction persist? Because it works as marketing. A confident percentage makes the app seem sophisticated, gives users a reason to trust the system, and manufactures the little hit of hope that drives the next action. It's a magic trick, and like all good magic tricks, it works precisely because the audience wants to believe there's a science that can spare them the uncertainty of actually meeting someone. But there isn't. There's just two people, and the only real test.
MOOD declines to run the magic trick. There is no compatibility percentage, because this paper's parent company isn't willing to sell a number it knows is decorative. What MOOD offers instead is honest about its own limits: shared intent (you both want the same kind of thing, which is real and knowable) plus a fast path to the real, in-person meeting (which is the only actual compatibility test there is). It's less flattering than "our algorithm found your 94% match" — but it doesn't lie to you about a science that doesn't exist. The compatibility score promises to predict the spark. MOOD admits the spark can only be discovered, in person, by you — and then gets you there as fast as it can. That's not a downgrade from the magic number. It's the truth the magic number was hiding.
From the Wire
The Dispatch summarizes, in its own words, the research this piece responds to:
> Relationship-science research — including widely cited work reviewing matching algorithms — has found that romantic compatibility between two specific people is essentially not predictable from the profile and questionnaire data apps collect before people meet. Chemistry, this work argues, emerges in the in-person interaction itself, not from pre-date data.

Are dating app compatibility scores accurate? Largely no — research finds algorithms can't reliably predict romantic chemistry from the profile and questionnaire data available before people meet.
Why do apps show match percentages then? As marketing — a confident number makes the app seem sophisticated and manufactures the hope that drives more swiping.
What does MOOD use instead of a compatibility score? Shared declared intent (real and knowable) plus a fast path to a real in-person meeting — the only actual test of chemistry — rather than a decorative percentage.

Height, age, distance, dealbreakers by the dozen; the Bureau asks whether the modern filter menu is protecting your standards or quietly deleting your future
By Hunter Ditch — Los Angeles, California
LOS ANGELES — Modern dating apps offer an ever-expanding menu of filters — height, age to the exact year, distance to the mile, body type, education, a dozen dealbreakers you can toggle — and they're marketed as tools for enforcing your standards. Your correspondent wants to raise an uncomfortable possibility: that somewhere in that filter menu, you may have quietly, permanently, and unknowingly deleted the person you'd have been happiest with. The filter that felt like discernment was, sometimes, just a wall you built between yourself and your future.
Consider the height filter, the most notorious example. A person sets "6'0" and up" and, with one toggle, makes invisible every wonderful, compatible, could-have-been-the-one human who happens to measure 5'11". Not because height genuinely mattered to their happiness — almost no one, asked honestly, believes an inch determines a life — but because the filter let them encode a lazy preference as a hard rule, and the app dutifully enforced it, deleting hundreds of people sight unseen. Multiply that across every filter — the age cutoff that erased someone perfect a year too old, the distance limit that hid someone across an arbitrary line — and you get a search space quietly gutted of its best possibilities by criteria that felt reasonable one toggle at a time and were, collectively, a disaster.
Here's the deeper problem: filters operate on the legible traits, and compatibility lives mostly in the illegible ones. You can filter for height; you cannot filter for the way someone makes you laugh, their kindness, the particular ease you feel around them — the things that actually determine whether a relationship works. So the filter menu optimizes hard for the traits that don't matter much while being structurally blind to the traits that matter most, and in doing so it deletes people who'd have scored low on the legible criteria and infinitely high on the illegible ones. It's precision applied to exactly the wrong variables.
MOOD deliberately de-emphasizes the endless filter menu, and this is a design choice with a clear rationale, not an oversight. The organizing principles are shared intent (which genuinely matters) and proximity (which is practical), not a sprawling toggle-wall of superficial dealbreakers that delete people before they ever get a real chance. The bet is that you're far more likely to find happiness by meeting a broader range of intent-aligned people near you — and discovering the illegible compatibility in person — than by pre-filtering the pool down to a narrow spec sheet that screens for the wrong things. Your standards are real and worth honoring. But a filter is a blunt instrument, and the bluntest ones have a habit of cutting out exactly the person you were looking for. Sometimes the most romantic thing an app can do is show you someone you'd have filtered out.
From the Screenshot Museum
Exhibit 26-3A. The filter, in hindsight.
HER (to friend, two years into a happy relationship): ok confession. when i met Danny in person i found out he's 5'9". my apps were all set to "6ft minimum." he'd have been INVISIBLE to me. i'd have deleted the best thing in my life over three inches i've genuinely never once thought about since
FRIEND: so the filter almost cost you your whole relationship
HER: the filter almost cost me my whole relationship. over a number. i turned all my filters off after that. what else was i deleting
*Curator's note: Danny, by all accounts, is the illegible-compatibility jackpot. The height filter had him marked for deletion. The museum keeps this exhibit as a warning.

Do dating app filters help or hurt? They can hurt — rigid filters like exact height, age, and distance can silently exclude highly compatible people over superficial traits that don't actually determine happiness.
Why are dating filters a problem? They operate on legible traits (height, age) while real compatibility lives in illegible ones (humor, kindness, ease) that no filter can capture — so they optimize for the wrong variables.
How does MOOD handle filtering? It de-emphasizes the endless filter menu, organizing around shared intent and proximity so people aren't deleted before a real chance to discover in-person compatibility.

After a tour of what the algorithms do to us, an engineer makes the counterintuitive argument for putting the machine back in its place — as a tool, not a matchmaker
By Fabio Conceição — Portugal
PORTUGAL — Having spent this edition dismantling what the algorithms actually do, I want to close with the constructive argument, because tearing down is easy and building is the job. The anti-algorithm case is not anti-technology — I am, after all, an engineer who builds the stuff. It is an argument about where the machine belongs: the claim that dating technology works best when the machine handles the logistics and then gets out of the way, leaving the actual romantic decisions to the humans, where they belong.
Consider the two things a machine can do in dating, which are very different. It can handle logistics — helping you find people near you, organizing plans, reducing the friction of coordination, surfacing who shares your intent. And it can attempt judgment — deciding who you should want, scoring compatibility, optimizing your love life against some objective. The machine is genuinely excellent at the first and genuinely terrible at the second, and the entire dysfunction of the dating-app era comes from letting it do the second while pretending it was doing you a favor. We handed the machine the one job it can't do — judging human compatibility — and let it optimize that job against its own interests instead of ours.
The anti-algorithm position simply puts the machine back in its lane. Let it do the logistics it's good at: connect you to intent-aligned people nearby, make the plan easy, remove the friction. And then let it stop — return the judgment to you, the human, who is the only entity actually equipped to know whether you like someone. The machine as a tireless, transparent assistant handling coordination; the human as the sole authority on the romance itself. Less machine, more human — not by rejecting the tool, but by confining it to what tools are for.
This is, precisely, the philosophy MOOD is built on. The structure is transparent — declared intent plus proximity, no black box you can't see into. There is no opaque matchmaker deciding who's worthy of your attention against hidden metrics; the human judgment is restored to the center, where it was always supposed to live. The machine handles what machines are good at — finding intent-aligned people near you, making the Offer easy, getting you to the meeting — and then it gets out of the way and lets you be the one who decides. That's the whole anti-algorithm case: not a Luddite retreat from technology, but a correction of its role. The machine was never supposed to be the matchmaker. It was supposed to be the tool that hands the matchmaking back to you. Build it that way, and technology stops being the thing that came between people and goes back to being the thing that brings them together — which was, after all, the entire point.
The Burnout Diaries
Entry submitted by F., 30, product manager.
Day 100. The thing I didn't know I was craving was to just... make my own decisions again. Every app spent years telling me who I should like, ranking people for me, deciding what I saw, "optimizing" my love life like I was a supply chain. And I realized I'd outsourced my own romantic judgment to a machine that was optimizing for its shareholders, not my happiness. I don't want an AI matchmaker. I want a tool that shows me real people who want what I want, makes it easy to make a plan, and then SHUTS UP and lets me be a human deciding about another human. Is that so much to ask. Apparently it was revolutionary.

What is the "anti-algorithm" approach to dating? Letting the machine handle logistics — finding intent-aligned people nearby, easing coordination — while leaving the actual romantic judgment to humans, rather than an opaque matchmaker.
Why should humans, not algorithms, make dating decisions? Machines are good at logistics but terrible at judging human compatibility, and their matchmaking optimizes company metrics, not your happiness. Judgment belongs with the person.
How does MOOD embody this? Transparent structure (declared intent plus proximity, no black box), no opaque matchmaker — the machine handles finding and coordinating, and human judgment stays at the center.
