總的來說：名校產生的終生教授比較多。

這是去年發表在nature 一篇文章。

伯克利，哈佛，優米，UW madison, Stanford 產生出來的tenure tracked professor 最多。

在學術界有很大的影響力。

One in eight US-trained tenure-track faculty members got their PhDs from just five elite universities: the University of California, Berkeley; Harvard University in Cambridge, Massachusetts; the University of Michigan in Ann Arbor; Stanford University in California; and the University of Wisconsin–Madison.
