As somebody who has spent a bit of time in academia, I have often been slightly alarmed by some of the research (and opinon) that comes out of business schools. One thing is that it is often unsubstantiated and just plain wrong, another is that it often seems like the authors kind of know it, almost as if they are intentionally pandering to a lowbrow/midwit audience, and they expect everybody else to be in on the game. Its mystifying.
Business school writing frequently smells like Post hoc rationalisation to me (with some confirmation bias mixed in).
Not at all limited to business schools
I had the privilege last night of attending a lecture given by Prof Sir John Kay (Obliquity, Radical Uncertainty, etc). He was scathing on two points: 1) the way the world changed in the 1970s from management as responsibility to leadership as prize, and 2) the abject failure of business schools to develop a serious body of knowledge. Taken together, business schools have become cash cows for universities while still being held in disdain by academia. This from the first dean of Oxford's Said Business School.
