From NBC San Diego, via Drudge Report:
Scientists Find 'Liberal Gene'.
So...Social Butterfly = Shallow Thinker? Wow! Never saw that one coming! (Oops! Did I say that out loud?)
This reminds me of a quote I read by the science fiction writer Robert A. Heinlein:
"Political tags - such as royalist, communist, democrat, populist, fascist, liberal, conservative, and so forth - are never basic criteria. The human race divides politically into those who want people to be controlled and those who have no such desire."
Of course, all of these guys could be completely wrong...
