May I also add a lot of good common sense is as big a plus as above average intelligence.
There are plenty of intelligent liberals with the common sense of a rock. The term educated fools might be the best term for them.
My son is extremely intelligent and so far it seems to be a reason for him to think he does not have to work. If any homework takes him more than 5 minutes he starts getting upset. A friend was complaining about his learning disabled son who works on his homework until 11 o clock at night but does not get much done. I told him his son had learned something very valuable, a work ethic. It will serve him well in life.
