I disagree.

Being social has to do with empathy which has to do with emotions and feeling what other people are feeling. Without empathy there is not too much cooperation. That's what I think anyway.
But I do think this might be a gender diffenrece, a bit at least. I mean, long ago, the female had to be more empathical because they were doing the stuff at the home cave in cooperation with other females (raising kids etc.) and the men were hunters. Quite different skills and needs for these different "jobs". A hunter with empahty doesn't kill anything.
Oh well, this is all my own speculation and, thus, shouldn't be taken too seriously.
