I would like to confirm that I've been highly influenced by Tetlock, and I appreciate his work. It was an integral part of a strategy in a business group I was running.

With that stated, if you can see beyond his vitriol, Nassim Taleb has some valid comments toward Tetlock's methodologies. I love Taleb, but hate his tendency to try and shock people. However, he does raise valid concerns about fat tails.
