Common sense - aka the ability to reason and act appropriately to a situation - is one of the many markers of IQ. Societies with the highest IQ are best prepared to survive hard times. One study makes much of the fact that IQ is only partly acquired through education and environment. It is also tied to genes and race, but not gender. This would not be seen as "politically correct" here. Inhibited we certainly are, but I agree that we are better off here than almost anywhere else in the world right now. Just so long as we don't f@#k it up.
