My take is that it isn't about serving non-committal matches and withholding promising matches or whatever, it has more to do with whether you feel like there are better matches on the app if you just keep lookin or waiting. I can see how and app using the stable matching algorithm could really make you feel like you're getting the best match you're going to get, which I think could have a real impact on commitment.

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.
