By what standards do you rank us? Half of us are stupider than average. We're all of very limited intelligence - the best we can do is to team together to function as one gigantic brain of humanity, drawing from the strongest qualities of all of us. That way the world can be brought forward by brilliant scientists who are completely stupid in their own way, and who would never survive a week on their own.

Politics are tricky, but I think it's more fruitful to think of people as brainwashed than stupid. The amount of propaganda we're subject to these days is unprecedented.

As for general stupidity, be charitable; judge people by what they're best at. Most people have over thing or another they are great at, and our differences is what makes humanity occasionally great.
