Interesting look at the structure of institutions. I really enjoyed the opening chapters which describe the writers way to this book, a little mini-history of Pierre Bourdieu's life and turn from anthropology to sociology. Of course the book leans heavily on Bourdieu's work, bringing in recent-ish examples of how silo-ization of institutions really hurts risk assessment and progress. I skimmed some of the examples because it is a bit of more of the same, but the author clearly presents it as a series of examples one can read or not depending on one's interest. Sharing information, ideas, people, in the end, is a good. Secrecy and protectionism never ends well, kids.
