I've been wanting to write about this, and this is as good a time as any: We have evolved this far, not in spite-of, but with the help of stupidity. You cannot have a successful company where everyone is exactly the same intellectual type.<p>What you call "stupidity" is often just a lack of curiousity - such people are the workers of society, the ones who don't get bored. Just because you belong to the "curious" caste does not mean you are better than the others, it just means you have a different role. If you had to do what the uncurious do you would have problems coping, because you would constantly get distracted.<p>Stupidity is not an insult. It's an attribute - and a large part of our evolutionary success is built on this specialisation of humans into the different intellectual roles.
