> I would postulate that academia and journalism are still pretty sexist
Two industries I have not had the pleasure of engaging with. My coaching experience has been around healthcare, insurance, banking, transportation, energy, construction, software, audit, and a few other random things.
I would postulate that academia and journalism are still pretty sexist compared to the 'tens of businesses' you observed.
Potentially in support of your perspective: I see the overspeaking roles inverted in the context of reality TV shows, though that could potentially be seen as a counter-action to normal social roles which develops as structure of society is removed... which would imply the sexist paradigm is the prevalent one.
