It is a touch of a generalization, however there rings truth to it. If you think about it, they growing up are expected to be more social than men. I can't give a complete breakdown of this as I am not a sociologist. I am merely drawing from experiences. I have met men that are amazingly socially aware. However I find most men aren't. Whereas I find more women to pick up on subtle social cues.
I'm not aware of the expectation of women to be more social than men. I actually don't think it's true. However, I do believe that they socialize differently.
From a pickup perspective, women tend to be more social because they are normally the ones being approached as opposed to approaching. They have the option to accept or reject an approach. Since they don't have much to lose in a social setting they get to operate with the mentality of having nothing to lose. Men on the other hand don't have that same luxury because we approach. Most guys are self conscious about approaching so it may seem like they are socially inferior to a woman but put the man in an environment where he is in the position to demand respect, that guy becomes the most socially accepted person in the room.
Where I'm going with this is that "women are far more socially intelligent than men" type of thinking gives guys more reason to be afraid of women when the entire premise isn't really true because even the hot ones can be awkward once you peel them away from their group. If you carry yourself well, can be charming, and get your intent out there, you'll get women to follow your lead. Just don't be one of those guys that put on fronts of what they think the girl wants because they'll see through that and then you'll look like a social idiot.
Other than that...great post.
