As a former hep-th guy from a very reputable institution I was ready to at least skim and briefly evaluate 36 particle physics papers. Turns out most of them have nothing to do with physics. It takes a special kind of personality to have the hubris to publish in so many domains at once, and most Harvard/Princeton/etc. physicists I know would probably be critical of this. Not that the disapproval would mean much.

(I did learn much of my QFT from Schwartz’s QFT textbook though, so I hold him in higher regard than <insert random Harvard Physics prof here>.)
