So why wouldn't a dating site just put its users through trusted high-power psychological screening instruments, to determine that sort of stuff? They're just questionnaires, mostly; they can be done entirely through a web/mobile UI, and scored without any humans in the loop.
Do the developers of dating sites think that people will consider it too much of a bother to fill out such things, or consider such questions too invasive? I don't know why; people love personality quizzes.
(IMHO you could make the whole site just a BuzzFeed "what kind of person are you? take this quiz to find out!" site at its core, except through all the quizzes you're doing, it's building up a very thorough psychological profile of you; and when it's got enough, it opens up the ability for you to date through it.)
