All in all it was a pretty good TED talk.  He kept me interested in the beginning with some of the jokes and powerpoint slides but started losing me when was trying to make his point at the end.  One thing I found very interesting though was when he quoted Sent-ts'an.  Sent-ts'an said, "The struggle between 'for' and 'against' is the mind's worst disease". That is so true and sadly there is no escape from this "disease". But by thinking that way for a second, Haidt says that we can "step out of the moral matrix" and change the world for the better by giving others opinions a chance at being right.

Not only would it not satisfy anybody but it would also require a lot of transaction costs.  It would simply be a waste of time.
