That's missing the point of this question, which is "if I read all the academic books on CFAR's list, are there blog posts that contain things I will not have seen in the books?"
That's not how I read it. It seems to me that it was only talking about the popular books, not the academic books.
I've read a few of the Sequences (probably about 50-100 individual posts), but I've only occasionally come away with insights and perspectives that I hadn't already thought of or read elsewhere. I've read a bunch of the popular books on cognitive science and decision theory, including everything on the CFAR popular books list. I'm also about to start an undergrad in statistics with a minor (or possibly a second major) in philosophy.
My question is: Are there specific LW posts / Sequences / other rationalist blog posts that I should read that won't be covered by standard statistics and philosophy courses, or by the books on CFAR's popular reading lists?
