WHAT THE MATCHING ALGORITHM ACTUALLY OPTIMIZES FOR

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.
