Good video, and yes, it's too bad the audio quality was poor for the interviewer.
I will very likely buy the book when it's released - the author is credible, and if his writing is similar to his speaking, he'll be easy to read. I'm not really interested in converting anyone, but I'm always interested in the thinking process. I may be giving undue credit without the book being released yet, but it certainly sounds like the method could be applied to pretty much any unquestioned beliefs. That would be useful, we've all been guilty of holding on to unsupported beliefs somewhere along the way; I still discover new treasure troves in my own head all too often.
