I’d want a source on this because an algorithm matching people does not seem to be the most effective. yes there are special occasions where lifetime partners have met online but I don’t think online dating is the sole purpose behind the decline of marriage.
Currently waiting for class to start so I can’t search for a link right now but iirc, the economy health is one of the main driving force behind marriage numbers dropping. In a healthy economy, more people are willing to marry, start a family, purchase land, etc. When economy is bad, all of these extra costs become more of a risk than before.
A system which showed people to each other in a totally randomized way would still drastically increases the number of people you can superficially evaluate, and even a tinder style photos + blurb profile is rich in personality/cultural clues to base evaluation on.
Is this really the ultimate goal for online dating? To expose us to a plethora of options in order to choose which one is best fit. It reminds of how Hot or Not could be seen as an early type of online dating that exposed us to randomized people, although without the option of being able to communicate with them beyond.
(Anecdotally, having used multiple apps, there is one that seemed to effectively "learn" my preferences and was successful in showing me women I was interested in meeting at seeming better than chance. But that's a single data point, and it's possible I'm "oddly predictable" from their model's perspective)
Instead, I have what appears to be never ending choices which makes it very unlikely I'll ever feel confident committing because 'the next one could be better', leaving me contently or unhappily single.
So, it seems like a wash now that I frame it in my own life...
I never presented this as scientific fact, nor based on the algorithms. I agree with akavi comment on your post. That has been my experience.
