Brilliant little chart program here where you can type in a trait or word and see (based on major) whether men or women professors in those fields are described as such.  It is based on RateMyProfessor.com and the data is just too funny and telling.

I've tried the follow search terms:

Entertaining
Funny
Pointless
Rambles
Fell Asleep

the best one, however is

hates men/hates women.

Also, do not just look at the sex ratio, also look at the difference between STEM and non-STEM.
