Wow...Taleb seems to be going off base a little. Kakutani may be simply commenting on Taleb's link between mammograms ans a doctor's actions, which seems like a factual logical error on Taleb's part re: causation. The second link -- Taleb's own words -- are so confusing as to be meaningless. I still think Taleb has done great work but he is guilty in Antifragile of doing what he accuses the world of doing; building a system based on scant and contradictory evidence. He's becoming the the tipping point guy. As to Kakutani's review, it seems fair and respectful, but she has been accused of being a bully: http://www.huffingtonpost.com/2012/08/28/worst-book-reviews_n_1834631.html
Yeah, Julie, Taleb seems to be turning into a one-man band of overweening self-righteousness. Maybe his next theme should be Antiboring.
