The brainiacs over at OKCupid — a dating site incubated by a bunch of Harvard math geeks in ’04; also where I met my music-nerd future-hub in ’09 after being a member for all of a 48 hours — recently crunched a few numbers to analyze the effectiveness of users’ profile pics. (Effectiveness = how many contacts were received monthly.)

What they found, which they’ve published in a lengthy, graph-dense screed, blew them away: “In looking closely at the astonishingly wide variety of ways our users have chosen to represent themselves, we discovered much of the collective wisdom about profile pictures was wrong.”

Specifically:

* It is not better to flash a pearly grin; instead, keep lips sealed and upturn your mouth corners coyly-yet-half-assedly. Females should do this while making “flirty eyes” at the lens; males should do this while gazing off-camera.

* By all means, do use a self-shot pic taken on a cell or webcam; what you forsake in high-pixel polish you’ll recoup with “an approachable, casual vibe that makes you feel already close to the subject.”

* Chicks especially can cash in big-time with the cell/webcam pic’s stylized subset: the  “MySpace shot,” which even OKC can only put into words as “taken by holding your camera above your head and being just so darn coy.” Like porn — which, c’mon, that’s what the MySpace shot is, right? First cousin to an American Apparel ad? — it’s hard to define a MySpace shot, but you know it when you see it. And when dudes see it, “the MySpace shot is the single most effective photo type for women,” annihilating the second most effective (in bed) by about 3-to-2. (And it’s not just because of the shot’s down-the-shirt angle, according to OKC’s stats.)

* Males fare better not wearing a shirt than wearing one… gah, hard to read much past this without short-circuiting my keyboard with the tears I weep for the future. The second half of the article talks about how old dogs (i.e., me, 35yo) should not learn these new tricks, as the backfire ratio swoops skyward the older you get.

AKA, OKCupid is not OK for “cougars.” Unless (and yes, I unfortunately do speak from experience here*) you do not mind being bombarded with IM requests from Fordham sophomores (and UPenn juniors and NJIT frosh…) to come see their dorm rooms tonight, because they’ve slept with tons of older women and they know just how to push your buttons and maybe they can show you how to use a webcam since when you were born phones actually had dial tones.

* Actually, it was pretty entertaining chatting with them.
