The Harvard Educated In Their Own Words

Sissy Willis presents the words of some Harvard elites explaining why they are elite.

"I think it is fair to assume that most Harvard graduates are of above average intelligence and education and tend to believe in such things as evolution and global warming.

I'm not sure which proves which, whether belief in global warming is proof of above average intelligence in Harvard grads, or belief by Harvard grads is proof of global warming.  I think maybe option two.
