People end up dating their opposite-gender clones, regardless of abstract criteria.
What I find ironic is the commercials make it sound like there's so much psyche matching going on, but then they show you Stepford couples.
And there seems to be one questionable goal: finding you someone who is exactly like you. Does that really work? Many relationships that last, the couple had nothing in common. If someone is the same as you, wouldn't you eventually get bored with that, and not develop in anyway? Maybe, maybe not.
