Not everything can be neatly quantified and sometimes we just have to deal with less than perfect information.

The point at the heart of this book is a good one, if a lot less radical than the authors imagine, and if the book had stopped after part 2, it would have been really good.

Unfortunately, it doesn't. What we get instead is a series of anecdotes, some of which manage to actually undermine the authors' core point, and which are repeated and restated to the point that I utterly lost the will to continue.
