They studied 7,000 photos and determined that men who didn't look directly at the camera in their profile pictures received more messages on average than men who did. About 50 percent more, in fact, if said picture combined the looking away with an expression of disinterest (smiling drove down the effect some, but still not as much as eye contact)."
and this:
"We really hate to say it but women are scientifically proven to like "bad boys." Apparently there is something called the "dark triad" (dibs on the band name) of personality traits that still exist and even flourish in humans despite the fact that, evolutionarily, they are bad for the continuation of the species.
They include exploitation, thrill-seeking/callous behavior and self-obsession. Since people like this are assholes, science dictates that they should have been bred out of the gene pool a long time ago. Of course, they weren't. And it's because the ladies love bad boys."
aaand this:
"In a recent study, men chatted with attractive women and then were subjected to basic tests. They failed miserably. And when we say "basic tests" we don't mean fourth grade math, either. We're talking not being able to remember your own address"
