The title is this book's worst feature - Klein re-branded the book and in so doing went from a strong if dry original title ("Intuition at Work") to the more sensationalistic one that drops him through the very trap door he seeks to avoid: making it sound as if "intuition" is just some kind of macho-mystical "gut feeling", rather than a mental process that runs parallel to conscious rational thought and that, if harnessed appropriately, can add enormous value to decision-making.
The book itself is a moderately well-designed program for applying the insights Klein shared in Sources of Power. Although it's full of problems (see below), I've never read anything like it, and the valuable bits are exceptionally valuable: strong, pragmatic, grounded advice on how to make the wispy world of intuition and "hunches" clear, concrete and useful.
Among the book's problems is that it doesn't know whether it wants to be a truly hands-on how-to manual - in which case it would have needed to be simplified and more action-oriented - or a research-driven exposition on how intuition can be used in the workplace - in which case the occasional how-to content is a jarring departure from the more illuminating case studies and research findings.
If you want to better understand and harness a whole hidden world of deeply insightful thinking - your and your colleagues' intuitions - there probably isn't a better book out there.
I just wish there was.
