Oh, could you blooming stop with that end of the world thing, I can't see it anymore that everyone has to tell the world how they think it's true/all crap.. guess what THE WORLD DOESN'T CARE. Either way.
I can however contribute with a small titbit, being something I heard about an experience some researchers made with mice (or rats, doesn't matter). They placed them in an environment where they had all they needed, and after some time, the animals started to become more and more psychotic. I don't want to make any interpretation of that, but maybe we should just keep in mind that a perfect society isn't necessarily something we can cope with yet, nor is it the inevitable end of the world.
Lastly, the average IQ has been on the rise for the past century due to the widespread usage of education.
That doesn't mean that people back then were totally dumb; they weren't. Of course education helps developing your thinking skills, but there have always been intelligent people around, in all civilizations and classes. They weren't much dumber in average than we are, in fact some American researcher is convinced we've become much less crafty at certain things than, for example, the Greeks. Not that I think it's true; I'm convinced the potential IQ has stayed stable all the time during, and education only helps to develop in cases where it's needed. Much more important than IQ is the contribution of education to the general knowledge and rationality of people.
