I think that there's a correlation between intelligence and unhappiness, but it's not a direct cause-and-effect thing. Like Doopa said, there are retarded folk who are depressed, and there are really smart people who are happy.

I think, however, that intelligent people are smart enough to realize how much they DON'T know, or spend time wondering about all the possibilities that could potentially have allowed for a better position in life.

Stupid people tend to only see what's in front of them. One guy I know smashed up his truck in an accident and was happy about it because now he had an excuse to buy a new one. This guy works in a factory for $8.00/hr putting screws in boards on an assembly line.
