A great resource for any of us who need to understand negotiation and the psychology of decision making (which you could argue is all of us). This is packed with interest, well researched examples of theories in practice and tips about how these can be put to work
Some readers seem to feel that Surowiecki stretches this idea further than it really deserves thus leading to some repetition or padding. It didn't feel that way to me. Using genuinely interesting examples the author makes a case for how and why the wisdom of crowds works before going on to clarify the conditions that differentiate this approach from a simple matter of asking a bunch of people what they think and averaging the results. In addition to being just long enough it's also well narrated although the production standards are poor; hence the dropped star. Ten minutes in I no longer noticed the slightly muffled delivery.
There are some excellent books out there that explain how the current economic slump came about. The Big Short is a great example of that approach. This Time Is Different is great on how things are likely to unfold from here. Not very cheery but extremely solid in its evidence base. Paul Krugman manages to do something different in as much as he gets off the fence and tells us how to fix it. You might not agree with him but he's got an engaging style, the ability to explain complex concepts in a clear and entartaining way and a Nobel prize on his side.
