I'm not sure that's true. The traits "known" are more subversive. Did you meet at a country/city club? At a gym? An upscale restaurant or bar? Do you have an accent? What are you wearing? What are you drinking? What do your friends look like? How do you carry a conversation? What unconscious body language and facial cues do you communicate?
I'm willing to bet that I could reliably predict 80%+ of whatever profile attributes you fill out online, with a 2 minute conversation and good look at you.
Aha! But that's the point. A 2 minute conversation can convey a lot about the person which a glance at a profile (or algorithmic filter) never could. That can produce the interest or chemistry.

Hahaha—I have a pretty good track record at the game, "spot the software industry dude" on hiking trails. We have a certain look and demeanor. Our preference for conspicuously-expensive outdoor gear from the right brands (not "hick" or "red" brands) does make it relatively easy as such games go, though.
