Yes it's almost a truism that the more schooling a person has, the stupider they get.
The amount of learning about the universe a person can pursue it limitless so in a university situation the field of study is necessarily narrow, and narrower the further you go. Condoleezza went far in skool but those who know her field of study have found she really didn't know much.
It has been said that Economics is an example of a discipline that has very little academic rigour and is more or less a faith. I suspect that the same forces that made it that way also took over the pharmaceutical thought operation a century ago as well.
Specialization out of relevance is what happens. It's commonplace for advanced adademics and scientists to have no idea of the world around them, especially the political dimension of their specialty.
Yes, I've also noticed that the Condoleezza-type use that beautiful extended vocabulary to say absolutely nothing. Too much fluff words when addressing all peoples. No answers, just fluff.
