Pretty reasonable generalizations.
I'd just like to add one more. Conservatives are highly independent and aren't adverse to risk. They are more willing to climb the ladder instead of traipsing off to college in pursuit of education [grants]. They search for business opportunities through employment experiences.
As far as liberals having a higher IQ? I have to laugh. I hear all the time on NPR that IQ tests mean nothing. They're not a true measure of cognitive ability. "There is no reliable average".
