I like the idea of scientist-run dating apps, although it does create its own potential conflicts of interest: the purity of the experiment and publishibility of experiments vs the needs of the participants.
I do think overall part of the reason dating experiences are so bad is that people aren't that good at identifying what traits are actually important in a partner for them, nor determining whether an individual has those traits.
Definitely seems like a space ripe for disruption in any case.
