Stanford actually has a reputation for forcing students to get Ph.D. rather quickly. Good point about the teaching thing. As far as I know, grad students don't teach in British colleges. They also don't have to take classes for ~2 years, which they do in most American colleges.
Students aren't divided into undergraduate/graduate in the UK but undergraduate/postgraduate students but that's just a question of terminology.

As for this whole debate on intelligence, it's widely accepted these days that intelligence isn't described in binary terms. You can't evaluate someone and come up with a result: intelligent/less intelligent. There are so many areas of intelligence that you can't come up with a simple result and as for IQ tests and associations like Mensa, they haven't been taken seriously since the 70s/80s. They were just a fad after WW2 but were quickly refuted by most experts for evaluating a tiny area of human intelligence.

Taking examples of films is never a good idea but Rainman (well since it's based on an actual person) is proof that you can have analytical abilities but totally lack any other intellectual abilities.
