But there's several ways to dissect this data. For example, the number of unsolicited messages that a man gets and the number of followups (and perhaps, how fast those followup messages occur) is probably a good insight to how "attractive" he is.
Now if you think its harder to determine this for females because the amount of noise that they get...then the computer can factor in the number of "attractive" men (as judged above) who fawn over you, either by messaging or stalky profile views.
And of course, number of profile views (over time) and by repeat viewers (indicating the number of obsessed secret fans you have) is probably a good baseline to start from.
Okay but obviously we know that's not a real picture, but instead a hyperbole of a photo. Still proves your point, I suppose. It's fun meeting people in real life then finding them on Facebook and seeing their complete lie of a profile picture that makes them look 3-4 points higher on a 10 point scale than they really are.
