Interesting book but seems to be lacking something but I cannot say what.

Some of the examples seemed far fetched.

Yet one of those examples I thought far fetched, opened up a new way of thinging for me in a related situation...

This book seems like one to influence more on an unconscious level than on a conscious level.

I would have loved to see where the boundaries are when discussion causes group think and when it does not.

Model: wisdom = aggregated local knowledge

Main concept to keep in mind is that of local knowledge with bias and information.

Where the right aggregation.

With a diverse crowd averages out the bias and keeps the information. While a not-diverse crowd with the same bias, extrapolates the bias.
