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.
The points made are interesting but the author makes them time and time again and labours the point too often.
I don't know if he is trying to flesh out what should have been a briefer book or doesn't have confidence in his ability to explain the subject matter in a manner that the audience can understand.
I ended up becoming frustrated and thinking 'I know, you've said so five times already' when listening to this audiobook and is the only one I?ve not listened to all the way though. I think an abridged version would have been better!
There are far better science books out there about Emergence in my opinion - even though few are on audiobook yet.
