I think there is a false equivalence in your intial post, flob. Your examples of intelligence are reserved for the truly outstanding or amazing feats. That does not seem a fair distinction to me. I would suggest that virtually all forms of human endevour require the application of intelligence, problem solving, tool use, adaptation etc.
Throughout history there have been a small band of stand out genius types that help propel humanity forward - but thats the exception, not the norm.For every Einstein, there are millions of normal types beavering away in all fields of thought, who refine and improve existing knowledge and/or technology by very small increments, improving life for everyone whilst paving the way for the next flash of inspiration.
Your dismissal of the majority of humanity as unintelligent seems a bit harsh to me ;)
