Great invention, or greatest invention.
Too homogeneous
Surowiecki stresses the need for diversity within a crowd to ensure enough variance in approach, thought process, and private information.
Too centralized
The Columbia shuttle disaster, which he blames on a hierarchical NASA management bureaucracy that was totally closed to the wisdom of low-level engineers.
Too divided
The US Intelligence community failed to prevent the 11 September 2001 attacks partly because information held by one subdivision was not accessible by another. Surowiecki's argument is that crowds (of intelligence analysts in this case) work best when they choose for themselves what to work on and what information they need. (He cites the SARS-virus isolation as an example in which the free flow of data enabled laboratories around the world to coordinate research without a central point of control.)
The Office of the Director of National Intelligence and the CIA have created a Wikipedia style information sharing network called Intellipedia that will help the free flow of information to prevent such failures again.
Too imitative
Where choices are visible and made in sequence, an "information cascade"[2] can form in which only the first few decision makers gain anything by contemplating the choices available: once past decisions have become sufficiently informative, it pays for later decision makers to simply copy those around them. This can lead to fragile social outcomes.
Too emotional
Emotional factors, such as a feeling of belonging, can lead to peer pressure, herd instinct, and in extreme cases collective hysteria.
This is what happens when you have a game that counts, and managers are forced to do things that they would never do otherwise.
But let us be generous. We will not shoot them. We will not pour salt water into them, nor bury them in bedbugs, nor bridle them up into a "swan dive," nor keep them on sleepless "stand-up" for a week, nor kick them with jackboots, nor beat them with rubber truncheons, nor squeeze their skulls with iron rings, nor push them into a cell so that they lie atop one another like pieces of baggage - we will not do any of the things they did! But for the sake of our country and our children we have the duty to seek them all out and bring them all to trial! Not to put them on trial so much as their crimes. And to compel each one of them to announce loudly:
"Yes, I was an executioner and a murderer."
